1 Installation1.1 Ducting for DehumidificationThe DRYCOOL HD Dehumidifier uses a uniquearrangement of two air streams to accomplish the taskof providing cool dry air at high efficiencies. These area supply air stream and a reactivation air stream. Thesupply air stream is meant to dehumidify air for thespace being controlled. The reactivation air streamexpels the water vapor collected by the desiccantdehumidification wheel.Supply Air DuctGENERAL WARNINGS & CAUTIONSAll electrical work should only be performed by qualified electrical personnel. Repair to electricalcomponents by non-certified technician may result in personal injury and/or damage to the unit.Installation should be conducted by a qualified technician only and Munters and Munters affiliate are not responsiblefor injuries and /or damages caused by improper installation.CAUTIONMAKE SURE THE UNIT IS LEVEL.A 11.5" W x 12" H square inlet located on the same side asan 8” round outlet is the supply air intake for the unit. Thesquare inlet can be connected directly to the return air ductcoming from the central part of the structure.This duct should draw air from the central part of the structureand supply it to the isolated areas of the structure like smallerrooms. The ductwork of the existing heating system can beused to supply air to the structure. If the existing supplygoes to isolated areas of the structure, discharge the supplyof the DRYCOOL HD unit into the supply of the existingcentral system. DO NOT draw air directly from the kitchen,laundry, or basement. You may draw air from a basementthat is open to the structure. All flexible ductingconnected to the DRYCOOL HD unit should be UL listed.The supply outlet of the DRYCOOL HD is located onthe same side as the square supply inlet. A length of6 feet or more of acoustical flex ducting on the outletof the unit will reduce air noise from the blower. Alength of flexible ducting on all DRYCOOL HD ductconnections is recommended to reduce noise andvibration transmitted to rigid ductwork in the structure.Ducting the DRYCOOL HD as mentioned in sections 1.1requires consideration of the following points:Duct Sizing: For total duct lengths up to 25', use aminimum 8" diameter round or equivalent rectangular.For longer lengths, use a minimum 8" diameter or equivalent.Grills or diffusers on the duct ends must not excessivelyrestrict air flow.Isolated Areas: Effective dehumidification may requireducting be branched to isolated, stagnant areas.Use 8" or larger diameter branch ducting to each oftwo or three areas; use 4" or larger to each of four ormore areas.Connecting to existing HVAC systems: An optional 8"check damper can be installed to prevent reverse flowthrough the unit. If the DRYCOOL HD is ducted to thesupply of a high static air handler the check damper maybe placed in the unit supply duct.Ducting Reactivation AirA separate set of duct connections are provided for theDRYCOOL HD dehumidifier for the reactivation air. Thereactivation air is meant to convey the water vapor capturedby the desiccant wheel away from the unit and outsidethe structure.The reactivation outlet connection is an 8" round connectionlocated on the opposite side of the 12" W x 13.5" H squaresupply air inlet. For total duct lengths up to 25’, use aminimum 8” diameter round or equivalent rectangular. Theduct should be brought to an outside wall or louver so that“wet” reactivation air is expelled from the space and to theoutdoors. Use a conventional dryer vent with back draftdamper for penetrating the wall if infiltration is a concern.Ducting for Fresh AirFresh air can be brought into the structure by connectinga duct from outside to the DRYCOOL HD unit inlet and byturning on the fan switch or activating the humidity control.The fresh air duct must be connected to the return air ductof the central air system upstream of the DRYCOOL HDDehumidifier.1

Additional considerations are as follows:1.2.3.4.Outside air is filtered before entering the building.Outside air will be dehumidified before entering if theunit is running in dehumidification mode.Drawing air from outside and blowing inside aids inslightly pressurizing the structure. This helps preventdirty and humid air from entering elsewhere.Adequate exhaust fans are recommended in the bathrooms and kitchen.In cold climates or areas where the outdoor dew point is lowat times, ventilation can be used to dehumidify the structure.This is accomplished by bringing the dry, low dew pointair into the structure during these times. This approach isoften more economical than running the dehumidifier toremove excess moisture from the structure.In cold climates, it is critical to adequately ventilate toreduce the inside moisture content to avoid moistureaccumulating in the wall cavities. For example; in a housethat experiences condensation on the interior surface ofthe windows during the winter, increasing the amount ofventilation will often cure the problem.The DRYCOOL HD is designed to move 250 cfm. Aninsulated 8"diameter duct is generally sufficient to provideup to 75 cfm of outside air. Remaining 175 cfm of return aircan be mixed with this fresh air and ducted into the supplyintake of the DRYCOOL HD.1.1.4 Installation in Basement or Crawl Space with Existing Forced Air HVACAHUAHUConditioned Unventilated Basement InstallationVentilated Unconditioned Basement InstallationIf the existing system has multiple returns, select one todisconnect from the existing forced air system and use itfor the dedicated DRYCOOL HD return. Always select areturn from a central location in the structure in an area thatis always open to the rest of the structure.Do not use a return from a room that often may have itsdoor closed. If the structure in which the DRYCOOL HDis to be installed has an existing forced air HVAC system,utilize the HVAC system to make the DRYCOOL HD unitinstallation easier.Basement Installation: Install a separate 8" return duct forthe DRYCOOL HD in a central area of the structure. Ductthe supply of the DRYCOOL HD to an 8" x 8" x 8" tee/damper that is 20% open to the basement. Duct the otherside of the tee to the air supply of the existing HVAC system.Connect a 8" reactivation duct to the reactivation outlet toexpel moist air outside the basement.Crawl Space Installation: Install a separate return for theDRYCOOL HD in a central area of the structure. Duct thesupply of the DRYCOOL HD to an 8" x 8" x 8" tee/damperthat is 20% open to the crawl space. Duct the other sideof the tee to the air supply of the existing HVAC system.Connect an 8" reactivation duct to the reactivation outletto expel moist air outside the basement.2

1.1.5 Installation in an Attic with a Existing Forced Air HVACAHUAttic InstallationALWAYS install a secondary catch pan with a drain or float interrupt for condensate under the DRYCOOL HD in an attic.Locate a separate return for the DRYCOOL HD in a central area of the structure or draw air from return ductwork. Ductthe supply side of the DRYCOOL HD to the air supply of the existing HVAC system. Connect an 8" reactivation duct tothe reactivation outlet to expel this “moist” air outside the basement.1.1.6. Installation for Dehumidifying for a Stand Alone SpaceOne of the benefits of a DRYCOOL HD is the deliveryof dehumidified air to the space at approximately thesame temperature that enters the device. This allowsan owner to simplify the installation for applications orinstances where it is desired to maintain humidity levelsin one open space. In these applications the return airfrom the space is connected directly to the unit and thedehumidified air can be delivered directly back into theroom without the need to mix it with cold air coming from acentral air conditioning system.HUMIDISTATRETURN AIRSUPPLY OUTREACT OUTLETREACT INLETIf the space is a large common room and is open toother adjacent rooms, using the DRYCOOL HD canhave the effect of providing dehumidification to muchlarger connected areas or even a small structure. Watervapor diffuses from areas of high vapor pressure toareas of low vapor pressure. When large spaces aredehumidified with a DRYCOOL HD, areas of low vaporpressure are created and will induce water vapor movementfrom other connected open rooms without the needfor ducting.The figure shows how the unit draws return air from thecommon space or a ventilated closet and discharges thedehumidified air back into the space.STAND ALONESPACECLOSET OR OTHERSTORAGE AREAThe DRYCOOL HD requires the mounting of theremote humidistat away from the discharge in anarea that is representative of the larger space. As with allof the installation configurations of a unit, the reactivationair still needs to be ducted to and from the outdoors asshown here.3

1.2 Electrical Requirements/Humidistat InstallationThe DRYCOOL HD plugs into a common grounded outleton a 15 Amp circuit. It draws between 6 and 7 Amps undernormal operating conditions. If used in a wet area, a groundfault interrupter protected circuit is required.If an extension cord is required, it must have a minimum of16 gauge conductors if less than 25 feet long and 14 gaugeif greater than 25 feet long.Install the remote humidistat in a central area of thestructure where it will sense the relative humidity ofthe structure accurately. Do not install the humidistatwhere it may not accurately sense the relative humiditysuch as near HVAC supply registers, near exterior doors,or near a pool or spa. The installer must supply thewiring between the dehumidifier unit and the humidistat.Be sure to safely route the control wires to prevent damageduring installation. Be careful not to cross the wires whenconnecting the DRYCOOL HD and the humidistat ordamage to the transformer may result.The humidistat of the DRYCOOL HD is powered by a lowvoltage circuit and must NEVER contact or be connectedto a high voltage circuit. The control wires leaving the unitand the humidistat are color coded to prevent confusion.Be sure to consult the electrical schematic in this manualor on the front panel of the DRYCOOL HD before makingthe control connections.1.3 Condensate RemovalCAUTION The DRYCOOL HD removes largeamounts of moisture from the air and the devicemust be connected to a drain line that will carryaway the excess water. A trap in the drain line isstrongly recommended.The drain line should be connected to the 3/4” female pipethread adaptor on the front of the DRYCOOL HD.Care should be taken to install the drain line with acontinuous slop of 1" per 10' to assure proper waterremoval.An optional condensate pump may be installed if a lift isrequired to dispose of the condensate. The condensatepump kit can be ordered direct from the factory.CAUTION For additional safety, Munters alwaysrecommends that a catch pan with front switch beplaced under the DRYCOOL HD.An optional condensate pump may be installed if a lift isrequired to dispose of the condensate. The condensatepump kit can be ordered direct from the factory.1.4 Installation in a Structure with NoExisting Forced Air HVACWhen installing the DRYCOOL HD in a structure thatdoes not have a forced air HVAC system, a singlereturn for the DRYCOOL HD should be installed incentral open area of the structure. DO NOT locate thereturn in a bathroom or a kitchen. The supply of the unitshould be located in the remote areas of the structure(such as bedrooms, den, etc...). By ducting this way theair inside the structure will circulate through the DRYCOOLHD to be filtered and dehumidified. 4” diameter duct isrecommended for branches to the bedrooms, 6” diameterduct is recommended for branches to larger areas. Connectan 8” reactivation duct to the reactivation outlet to expelmoist air outside the space.1.5 Optional UV LightSafety Notices: Improper installation, adjustment, alteration,service, maintenance, or use can cause fire, electricalshock, or other conditions which may cause personalinjury or property damage. Consult your local authorizeddealer or Munters Corporation for additional informationor assistance.WARNING Before performing maintenanceor service on fixture, ensure unit is unplugged.Electrical shock can cause injury or death.• Never expose eyes or skin to UVC light from anysource. Wear gloves, face shield/glasses (perANSI Z87.1) and cover all exposed skin.• Do not touch Emitter glass without gloves.Damage to Emitter may result. Oil fromfingerprints will permanently etch glass ofEmitter. If necessary, clean Emitter usingoptional cleaning kit.• Voltages outside of the range designed for theunit will void the warranty and do permanentdamage to the entire unit.• Emitter contains a small quantity of mercury. Ifan Emitter breaks, clean and dispose with care.Note: Ensure that emitter is installed before power isapplied. Installing emitter after the power has been appliedwill trigger the “end of lamp life circuit” and emitter will failto light! If this happens, shut off power for 10 minutes andthen turn power back on. Emitter will then light.4

1.2.3.4.Disconnect power from the DRYCOOL HD unitRemove installation hole plug. This black plastic plugis located on the same end of the unit as the controlpanel and is above the condensate drain outlet.Insert support wire.Insert emitter into hole, ensuring that emitter ceramicend rests on support wire’s hook and that emitter collaris set firmly against hole perimeter.5.6.7.Cut spine in order to accommodate the support wire.Reinstall the spine pieces.Attach emitter extension cord to power supply, andplug power supply into the outlet on the DRYCOOL HDlabeled “UV Light”.Power can now be reconnected to the MuntersDRYCOOL HD unit.2 Intended ApplicationThe DRYCOOL HD Dehumidifier is intended for installationin spaces that experience short or long term highhumidity conditions. Use of the DRYCOOL HD in poolareas will void warranty. In order to efficiently controlhumidity levels, the area in which the dehumidifier is tobe placed must be free of water intrusion or excessivefresh air infiltration. Before installation of the DRYCOOLHD, water intrusion or excess air infiltration shouldbe addressed.8”REACT INLETDO NOT place the DRYCOOL HD directly on structuralmembers.A secondary drain pan MUST be placed under the unit.The DRYCOOL HD should be located near the existing airhandling system to minimize the required ductwork. Thecontrols for the DRYCOOL HD are remote from the unit andmust be located in the space that is to be conditioned. Thecontrols are low voltage (24 volt) and should be connectedto the DRYCOOL HD with low voltage thermostat wire.8”SUPPLY OUTCOND. COILSQUARE TOROUND(OPTIONAL)If fresh air ventilation is desired, thought should be given tothe location for the fresh air ducting. An 8” round insulatedduct will have to be installed on the DRYCOOL HDand run to the outside of the structure to bring in fresh air.The unit is not meant to condition more than 75cfm of outside air.

3 OperationThe DRYCOOL HD can be equipped with variousaccessories to enhance its operation. A remote humidistatmust be used with the unit.3.1 Humidity Control AdjustmentSet the humidity control to the desired humidity level forthe structure. Turning the knob clockwise on the humidistatresults in a drier setting.The dehumidifier will run continuously until the relativehumidity (RH) is reduced to the humidity control dialsetting. Setting the humidity control to lower RH levels willNOT increase the unit’s dehumidification rate; the unit willsimply run longer to reduce the area’s RH to the setting.The DRYCOOL HD (and refrigerant based dehumidifiers ingeneral) will reduce a conditioned space’s RH to a lowerlevel. Settings below 40% are not recommended.3.2 Fan/Filter SwitchTurning ON the fan/filter switch on the side of the unit willcause the DRYCOOL HD internal fan to run continuously,whether the unit is dehumidifying or not.This function is desirable if the unit is used for air circulationand filtration to achieve maximum indoor air quality. Whenthe switch is ON; air will be constantly filtered through theunit and circulated throughout the house. When the switchis OFF; the fan will operate only when the humidity controlcalls for dehumidification.Along with either the high efficiency filter and/or theGermicidal UVC, the DRYCOOL HD can be used to performtotal Indoor Air Quality control for your structure.4 Maintenance4.1 Standard Air FilterThe DRYCOOL HD is equipped with an air filter. This filtershould be checked every three months. Operating the unitwith a dirty filter will reduce dehumidifier capacity andefficiency and may cause the compressor to cycle off andon unnecessarily based on, or due to, high level pressureTo access the air filter, slide the filter out of the side of theunit. The filter can generally be vacuumed clean severaltimes before needing replacement. Replacement filters canbe purchased locally. DO NOT operate the unit without afilter. The heat exchange coils inside the unit could becomeclogged and require disassembly to clean.4.3 Germicidal UVC LightsContinuously operated emitters need to be replacedannually to maintain design output. As a note, emitter on/off cycles should be minimized in order to maximize emitterlife.No more than an ordinary light bulb - SteriLight’s uniqueEmitters are simply changed once a year. SteriLight isvirtually maintenance-free between change outs!CAUTION Do not look at UVC lights whenoperating without adequate eye protection. UVCcan cause damage to unprotected eyes.4.2 High Efficiency Air FilterAn optional high efficiency active electrostatic filteris available for the DRYCOOL HD. This filter is ratedas 90%-95% efficient by the ASHRAE Dust Spot testmethod 52-76. In addition Munters E-Filter, removes otherparticles not measured by the ASHRAE Dust Spot Test.This filter is able to remove allergy causing particles fromthe airstream. Check the high efficiency air filter every 4months and replace if necessary. Do not attempt to cleanthe high efficiency filter. It should be replaced when itbecomes restrictive.The UVC Air Purification System6

5 Service5.1 Technical DescriptionThe DRYCOOL HD uses a refrigeration system similar to anair conditioner’s to remove heat and moisture from incomingair. In addition a dehumidification wheel downstream ofthe evaporator coil removes additional moisture from theairstream in a vapor state.COMPRESSORTXVRefrigeration System of DRYCOOL HDTXEVAPORATORFILTER/DRIERCONDENSERHot, high pressure refrigerant gas is routed fromthe compressor to the condenser coil. The heatfrom the condenser is used to reactivate thedesiccant dehumidification wheel. The heat applied to thedesiccant dehumidification wheel allows water to evaporateoff the wheel and be discharged by the reactivation fan.The reactivation air needs to be ducted to the outside.The refrigerant is cooled and condensed by giving up itsheat to the air that is about to be discharged from theunit. The refrigerant liquid then passes through a filter/drier and capillary tubing which cause the refrigerantpressure and temperature to drop. It next enters theevaporator coil where it absorbs heat from the incomingair and evaporates. The compressor evacuates the coolrefrigerant gas from the accumulator and compressesit to a high pressure and temperature to repeatthe process.5.2 TroubleshootingFan runs with fan switch and ventilation timer OFF, butcompressor cycles on & off.1.2.3.4.5.Low ambient temperature and/or humidity causing unitto cycle through defrost mode.Dirty air filter(s) or air flow restricted.Defrost thermostat defective .Defective compressor overload.Defective compressor.Fan does not run with fan switch in either position.

CAUTION Servicing the DRYCOOL HD with its highpressure refrigerant system and high voltage circuitrypresents a health hazard which could result in death,serious bodily injury, and/or property damage. Onlyqualified service people should service this unit.5.3 Humidity ControlThe humidistat control is an adjustable switch that closeswhen the relative humidity of the air in which it is locatedrises to the dial set point. If the DRYCOOL HD does not run,try turning the humidity control clockwise until it reachesthe stop and the knob pointer points at “on.” If it still doesnot run, remove the stop screw from the panel and turn theknob farther. If it then runs, the humidity control is out ofcalibration.6 Options6.1 Active High Efficiency Air FilterAn optional active electrostatic high efficiency air filter isavailable for the DRYCOOL HD. This filter is rated 90%-95% efficient by ASHRAE Dust Spot Test Method 52-76.This filter is much more efficient than the standard airfilter and is able to catch much smaller particles that canaggravate allergies.Particle Size Typical Contaminant Capture Efficiency3–10 Microns Pollen, mold, dust mites, hair spray 99%1–3 Microns Auto emissions, lead dust, large bacteria 98.6%.3–1 Micron Smoke (tobacco, cooking), small bacteria, finedust, paint pigmentsVOCs (odors, offgasses including formeldehydefrom carpets, furniture, and cleaningproducts)Munters Active Electrostatic FilterThe high efficiency air filter is an electrostatic filter thatuses state of the art technology to clean air to a MERV 13rating.

UVC is atype of ultraviolet (UVC) energy in the 260-nanometerfrequency. The “C” wavelength is the most germicidalin the UVC spectrum. The “C” wavelength targets theDNA of microorganisms, causing cell death or makingreplication impossible. The UVC energy kills or inactivatesmicrobes, eradicating surface and airborne mold, as wellas viruses and bacteria.UVC is not an air filter. Rather it’s a UVC air purificationsystem, based on Steril-Aire’s multi-patented technology,used in thousands of schools, hospitals, and governmentand commercial buildings. This same proven technology isnow available for the structure.The UVC air purification system then uses germicidal actionto destroy the mold, bacteria and viruses that grow andcirculate in the air, before they travel around your space totrigger allergic reactions or spread disease.Benefits of UVC Air Purification Systems:• Kill the mold and bacteria that grow in your A/C system.• Reduce or eliminate allergies, allergy asthma and othermaladies caused by mold and bacteria.• Destroy circulating cold and flu viruses and otherinfectious microbes..3–1 Micron Smoke (tobacco, cooking), small bacteria, finedust, paint pigmentsVOCs (odors, offgasses including formeldehydefrom carpets, furniture, and cleaningproducts)Conventional Passive FiltersNot EffectiveNot Effective• Increase your A/C system’s useful life, reduce costlycleanings and save energy.• Make indoor air smell as fresh as the freshest dayoutdoors with an UVC air purification system.8OPTIONAL PARTS LIST: DRYCOOL HD Indoor Air Quality
