PRODUCT DESIGNASZ14 models are available in 1 1/2 through 5 ton sizes anduse R-410A refrigerant. They are designed for 208/230 voltsingle phase applications.The condenser air is pulled through the condenser coil by adirect drive propeller fan. This condenser air is then dischargedout of the top of the cabinet.These units are designed for free air discharge, so no additionalresistance like duct work shall be attached.The suction and liquid line connections on present modelsare of the sweat type for field piping with refrigerant type copper.Front seating valves are factory installed to accept thefield run copper. The total refrigerant charge for a normal installationis factory installed in the condensing unit. ASZ unitsare charged for the matching evaporator coil and a 15 footrefrigerant line set.Systems should be properly sized by heat gain and losscalculations made according to methods of the Air ConditioningContractors Association (ACCA) or equivalent. It isthe contractors responsibility to ensure the system has adequatecapacity to heat or cool the conditioned space.ASZ models use high-efficiency Copeland ® scroll "Ultratech"compressors which are specifically designed for R-410A refrigerant.There are a number of design characteristics whichare different from the scroll compared to the traditional reciprocatingcompressor."Ultratech" Series scroll compressors with Copeland ®ComfortAlert diagnostics will not have a discharge thermostat.Some of the early model scroll compressors requireddischarge thermostats.Due to their design Scroll compressors are inherently moretolerant of small quantities of liquid refrigerant.NOTE: Even though the compressor section of a Scroll compressoris more tolerant of liquid refrigerant, continuedfloodback or flooded start conditions may wash oil from thebearing surfaces causing premature bearing failure."Ultratech" Series scroll compressors use "POE" orpolyolester oil which is NOT compatible with mineral oil basedlubricants like 3GS. "POE" oil must be used if additional oilis required.WARNINGTo avoid possible injury, explosion or death, practicesafe handling of refrigerants.Operating pressures and amp draws may differ from standardreciprocating and/or scroll compressors. This informationmay be found in the "Cooling Performance Data" section.This unit is for outdoor installation only. Refer to minimumfigure for clearances from the sides of the unit to full wallsand other objects.NOTE: This unit cannot be completely enclosed. At leastone side must be unrestricted.4These clearances will help avoid air recirculation. If installingtwo or more units at the same location, allow at least 24inches between units. If only one side is restricted (for example,against the outside wall of a house), the unit may beplaced as close as 8" to that one wall.DO NOT locate the unit:* Directly under a vent termination for a gas appliance.* Within 3 feet of a clothes drier vent* Where the refreezing of defrost water would createa hazard* Where water may rise into the unit.AANOTRECOMMENDEDB B BAACCAAAAAACCAAAAMinimum Airflow ClearanceBAAOK!OK!OK!OK!OK!

System charge must be adjusted per Installation Instructions Final ChargeProcedure.• Installation of these units requires the specified TXV Kit to be installed on the indoor coil. THE SPECIFIED TXV IS DETERMINED BY THEOUTDOOR UNIT, NOT THE INDOOR COIL.NOTE: This data is provided as a guide, it is important to electrically connect the unit and properly size fuses/circuit breakers andwires in accordance with all national and/or local electrical codes. Use copper wire only.Unit specifications are subject to change without notice. ALWAYS refer to the units serial plate for the most up-to-date generaland electrical information.5
