Position dryer for theleast amount of exhaust piping and elbows, and allow free access tothe rear of dryer for future servicing of belts, pulleys and motors.Installation clearance from all combustable material is 0" ceilingclearance, 0" rear clearance, and 0" side clearance.Before operating dryer, open basket door and remove blockingbetween front panel and basket. Read the instruction tags, owner’smanual, warnings, etc.IMPORTANTOpening the clothes loading door deactivates the door switchto shut off the motors, fan, gas, steam, or electric element. Torestart the dryer, close the door and press in the push to startbutton and hold briefly.IMPORTANTThis dryer is designed for a capacity maximum load.Overloading it will result in long drying times and damp spotson some clothes.IMPORTANTMaximum operating efficiency is dependent upon proper aircirculation. The lint screen must be kept cleaned daily toinsure proper air circulation throughout the dryer.IMPORTANTProvide adequate clearance for air opening into the combustionchamber.Page 9

Unpacking/General Installation (All Dryers)GENERALINFORMATIONThe dryer is so designed that when an operator opens the dryerdoor, the basket and exhaust fan stop. You can expect fast dryingfrom a laundry dryer. Hot, dry air is properly and effectivelymoved through the basket and exhausted through a lint trap to theatmosphere. The dryer comes equipped with an inclined selfcleaninglint screen. In this system, lint accumulates on theunderside of the screen until a blanket of lint will fall from thescreen to the bottom of the dryer cabinet, and should be removeddaily or as required, to prevent an over-accumulation.IMPORTANTProvide adequate clearance for air openings into the combustionchamber.DRYER“COOL-DOWN”CYCLEPermanent press, durable press and other modern day fabricsrequire the care that your laundry dryers now provide. At the end ofthe drying cycle, a timed “Cool-Down” control automatically takesover and continues the rotation of the fan and basket without heatuntil the garment load reaches a safe cool temperature. Thisfunction is performed at the end of each drying cycle and continuesfor two minutes.REPLACEMENTPARTSReplacement parts for this dryer are available from your distributoror by contracting the factory at the address or phone number printedon the cover page of this manual.ONLY CISSELL PARTS SHOULD BE USED.Page 10

Steam Piping - Installation InsatructionsSTEAM PIPING-INSTALLATIONINSTRUCTIONS1. Set and anchor dryer in position. Machine should be level to assure propersteam circulation.2. To prevent condensate draining from headers to dryer, piping should havea minimum 12" (305 mm) above respective header. Do not make steamconnection to header with a horizontal or downwardly facing tee or elbow.3. Whenever possible, horizontal runs of steam lines must drain, by gravity,to respective steam header. Water pockets, or an improperly drainedsteam header will provide wet steam, causing improper operation of dryer.If pockets or improper drainage cannot be eliminated, install a bypass trapto drain condensate from the low point in the steam supply header to thereturn.4. In both steam supply and steam return line, it is recommended that eachhave a 3/4" 20 mm) union and 3/4" (20 mm) globe valve. This will enableyou to disconnect the steam connections and service the dryer while yourplant is in operation.5. Before connecting trap and check valve to dryer, open globe valve insteam supply line and allow steam to flow through dryer to flush out anydirt and scale from dryer. This will assure proper operation of trap whenconnected.6. After flushing system, install bucket trap (with built-in strainer) and checkvalve. For successful operation of dryer, install trap 18" (457 mm) belowcoil and as near to the dryer as possible. Inspect trap carefully for inletand outlet markings and install according to trap manufacturer'sinstructions. If steam is gravity returned to boiler, omit trap but installcheck valve in return line near dryer.7.

Exhaust and VentingDRYER AIR FLOWINSTALLATIONEXHAUST DUCTMAKE-UP AIROTHERRECOMMENDATIONSTROUBLESHOOTINGNothing is more important than air flow for the proper operation of a clothesdryer. A dryer is a pump which draws make-up air from the out-of-doors,through the heater, through the clothes and then forces the air through theexhaust duct back to the out-of-doors. Just as in a fluid water pump, there mustbe a fluid air flow to the inlet of the dryer, if there is to be the proper fluid airflow out of the exhaust duct.In summary, there must be the proper size out-of-doors inlet air opening (4-6times the combined areas of the air outlet) and an exhaust duct, size and lengthof which allows flow through the dryer with no more than 0.3” w.c.(.8 mbar) pressure in the exhaust duct.In some instances, special fans are required to supply make-up air, and/or boostexhaust fans are required for both regular and energy saving models.FOR BEST DRYING:1. Exhaust duct maximum length 14 feet (5 m) of straight duct andmaximum of two 90° bends.2. Use 45° and 30° elbows wherever possible.3. Exhaust each dryer separately.4. Use 2 feet (0.6 m) of straight duct on dryer before installing an elbowon energy-saver models only.5. Do not install wire mesh or other restrictions in the exhaust duct.6. Use clean-outs in the exhaust duct and clean periodically when needed.7. Never exceed 0.3” water column (.8 mbar) static pressure in theexhaust duct.8. Inside surface of the duct must be smooth.9. Recommend pop rivets for duct assembly.FOR BEST DRYING:1. Provide opening to the out-of-doors in accordance with the following:For each dryer—6 inches (152 mm) diameter exhaust requires a 1 square feet (0.1 m²)opening for make-up air.8 inches (203 mm) diameter exhaust requires a 2 square feet (0.2 m 2 )opening for make-up air.12 inches (305 mm) diameter exhaust requires a 4 square feet (0.4 m 2 )opening for make-up air.2. Use barometric shutters in the inlet air opening to control air whendryers are not running.Other RecommendationsTo assure compliance, consult local building code requirements.TroubleshootingHot dryer surfaces, scorched clothes, slow drying, lint accumulations, or airswitch malfunction are indicators of exhaust duct and/or make-up air problems.Page 29

Rules for Safe Operation of DryerRULES FOR SAFEOPERATION OF DRYER1. Be sure your dryer is installed properly in accordance with therecommended instructions.2. CAUTIONBe safe—shut main electrical power supply and gas supply offexternally before attempting service.3. CAUTIONNever use drycleaning solvents: gasoline, kerosene, or other flammableliquids in the dryer. Fire and explosion will occur.Never put fabrics treated with these liquids into the dryer.Never use these liquids near the dryer.Always keep the lint screen clean.Never use heat to dry items that contain plastic, foam or sponge rubber,or rags coated with oils, waxes or paints. The heat may damage thematerial or create a fire hazard. Rubber easily oxidizes, causingexcessive heat and possible fire.Never dry the above items in the dryer.4. Never let children play near or operate the dryer. Serious injury willoccur if a child should crawl inside and the dryer is turned on.5. Never use dryer door opening and top as a step stool.6. Read and follow manufacturer’s instructions on packages of laundry andcleaning aids. Heed any warnings or precautions.7. Never tumble fiberglass materials in the dryer unless the labels saythey are machine dryable. Glass fibers break and can remain in the dryerand could cause skin irritation if they become mixed into other fabrics.8. Reference: Lighting and shut-down instructions and wiring diagramsare located on the rear wall of the dryer cabinet.9. The dryer must not be installed or stored in an area where it will beexposed to water and/or weather.ENERGY-SAVING TIPS1. Install dryer so that you can use short, straight venting. Turned elbowsand long vent tubing tend to increase drying time. Longer drying timemeans the use of more energy and higher operating costs.2. Operate dryer using full-size loads. Very large loads use extra energy.Very small loads waste energy.3. Dry light-weight fabrics separately from heavy fabrics. You will useless energy and get more even drying results by drying fabrics ofsimilar weight together.4. Clean the lint screen area daily. A clean lint screen helps give faster,more economical drying.5. Do not open the dryer door while drying. You let warm air escape fromthe dryer into the room.6. Unload the dryer as soon as it stops. This saves having to re-start yourdryer to remove wrinkles.Page 30

Direct-Spark Ignition OperationDIRECT SPARKIGNITIONOPERATIONNOTE:Some models are equipped with a dual ignition system.The dual ignition system contains two direct sparkignition modules in parallel. Each module has its ownflame sense circuit and acts independently of the other.If either bonnet limit thermostat opens because of highheat or flame impingement, the entire ignition systemwill shut down.1. When a call for heat is received from the control supplying24VAC to the ignition control module, the pre-purge delaytimer begins. This delay time allows any air/sediment to beejected prior to burner ignition. Following the pre-purge delayperiod, the gas valve is energized and the spark ignitor sparksfor the trial ignition period.2. When a flame is detected during the trial for ignition period, thespark ignitor shuts off and the gas valve remains energized.3. If no flame is detected by the flame sense circuit, the ignitioncontrol module will go into safety lockout. The valve will beturned off immediately. If the module has multiple retries andno flame is detected, the gas valve is de-energized and themodule goes into an interpurge delay. After this delay, themodule will attempt another trial for the ignition period. Thiswill continue until the number of retries has been used up. Atthe time, the module will go into safety lockout.4. Recovery from safety lockout requires one of the following:a. A manual reset by opening and closing the loading door.b. After one hour if the control thermostat is still calling forheat, the module will automatically reset and the trial forignition period will start over.5. Opening the loading door will cause the flame to extinguish.Closing the door and starting the dryer will restart the trial forignition period.6. Once the control thermostat has been satisfied and/or thedrying timer has been timed out, the ignition controlmodule(s) will be de-energized, the gas valve(s) will be deenergizedand the flames will extinguish.7. The machine will continue to run in a cooldown mode withoutheat. This process will cool the load to the touch and help toeliminate wrinkling.Page 42

General MaintenanceGENERALMAINTENANCE1. Clean lint trap daily. Remove lint before or after each day ofoperation. A clean lint trap will increase the efficiency of thedryer and the moisture-laden air will be exhausted outside morequickly.2. Keep basket and sweep sheets clean. Clean as often asneeded. The basket and sweep sheets are accessible byremoving the front panel of the dryer.3. Gas burners, steam coils, electric coils. Check and clean often.4. Pulleys and belts. Keep clean, as oil and dirt will shorten thelife of a belt. Check periodically for alignment. Pulley shaftsmust be parallel and the grooves must be aligned. Check belttension periodically. Adjust tension by movement of idlerbracket. Lubricate idler pulley once every two months, using sixgrams of high temperature grease. Do not over-grease.5. Electric motor. Keep motor clean and dry. Motors are packedwith sufficient grease for 10 years normal service. After that,bearings and housing should be cleaned and repacked one-thirdfull with Chevron grease No. SR1-2. See label on motor forfurther information.If motor overheats, check voltage and wiring. Low voltage,inadequate wiring and loose connections are the main cause ofmotor failures.6. Adjustable leveling bolts. One at each corner permits accuratealignment of dryer.To adjust: Block one corner of dryer up off the floor, loosenhex nut. With wrench, turn bolt clockwise to raise dryer,opposite to lower. Rear bolts are outside of dryer and frontbolts are inside lint trap compartment.Page 44

Basket Shimming InstructionsBASKET SHIMMINGINSTRUCTIONSThis procedure is normally necessary when replacing either the basket or thespider assembly on any dryer. Proper shimming is crucial to obtain a truerunning basket.A. Align the basket as per instructions in the manual.B. Rotate the basket to determine where the most out-of-roundpoint is (where the basket scrapes or comes closest toscraping the sweep sheet).C. Mark this position and the nearest rib to this position.D. Remove the basket (do not loosen the alignment bolts).E. With the basket on the floor (spider up), place one or twoshims between the spider leg and the back of the basket atthe marked rib position. (see drawing)F. Re-insert spider and basket assembly and re-check cylinder.G. If at this point, basket is still out-of-round, procedure mustbe repeated starting with Step B.Upon completion of shimming process, realignment of basket isnecessary.NOTEIf the point mentioned in Step B is between two ribs, both ribsmight have to be shimmed.Page 51

Air Switch Adjustment (with Illustration)AIR SWITCHADJUSTMENT1. Shut off current; disconnect leads and remove air switch.2. Lay air switch assembly on flat surface. Adjust air blade at“A” (figure 1), so that air blade lays flat and surface “B” isparallel to the flat surface.3. Place 3/8" (10 mm) x 5/8" (16 mm) spacer bar or equivalent “C”(figure 2), under air blade in position shown; hold switchmounting bracket firmly and adjust switch actuator “D” withneedle nose pliers at “E” by twisting actuator right or left,whichever is needed, so that switch closes when end of airblade engages bar “C”.4. Maximum opening of air switch must be no greater than 3/4"(figure 3). Bend tab “F” in or out to maintain this dimension.5. Re-install air switch assembly on rear of dryer.6. Re-check operation of air blade. Switch must close before airblade engages face of opening and re-open before stop “F”engages.Page 52

Dryers with Reversing Control TimerINSTRUCTIONS FORDRYERS WITHREVERSINGCONTROL TIMERInstructionIn operation, coasting of basket increases, making it necessary to readjustreversing timer.CAUTIONFailure to do this will cause the thermal overload units for the basket tocut-out unnecessarily and probably damage the gear reducer.Adjustment of reversing timer dwell timeCAUTIONDryer power supply must be shut off before adjusting timer.The dwell time is the time from when the motor turns “off”, to when it turns“on” again in the opposite direction.Turning the dwell adjustment knob counter-clockwise increases the dwell timeand turning it clockwise decreases the dwell time.Recommended dwell time for the basket to stop completely is 5 to 7 seconds.Minimum basket stopping time is 4 seconds.NOTE:Select non-reversing or reversing before starting dryer.Page 55
