7 3.0 LOCATING UNIT 3.1 CORROSIVE ENVIRONMENT The metal parts of this unit may be subject to rust or deterioration if exposed to acorrosive environment. This oxidation could shorten the equipment’s useful life.Corrosive elements include, but are not limited to, salt spray, fog or mist in seacoastare...

9 4.0 REFRIGERANT CONNECTIONS All units are factory charged with Refrigerant 410A. All models are supplied withservice valves. Keep tube ends sealed until connection is to be made to preventsystem contamination. 5.0 TOOLS REQUIRED FOR INSTALLING & 5.0 SERVICING R-410A MODELS Manifold Sets: -Up t...

10 6.0 REPLACEMENT UNITS To prevent failure of a new condensing unit, the existing evaporator tubing systemmust be correctly sized and cleaned or replaced. Care must be exercised that theexpansion device is not plugged. For new and replacement units, liquid line filterdrier sould be installed and re...

• If tubing is to be run underground, it must be run in a sealed watertight chase. • Use care in routing tubing and do not kink or twist. Use a tubing bender on thevapor line to prevent kinking. • The vapor line must be insulated to prevent dripping (sweating) and preventperformance losses. Armaflex...

14 10.0 EVACUATION PROCEDURE Evacuation is the most important part of the entire service procedure. The life andefficiency of the equipment is dependent upon the thoroughness exercised by theserviceman when evacuating air and moisture from the line set and indoor coil. Air in the system causes high ...

15 13.0 CHECKING REFRIGERANT CHARGE Charge for all systems should be checked against the Charging Chart inside theaccess panel cover. Before using the chart, the indoor conditions must be within2°F of desired comfort conditions and system must be run until operating conditionsstabilize (15 min. to 3...

13.3 FINAL LEAK TESTING After the unit has been properly evacuated and charged, a halogen leak detectorshould be used to detect leaks in the system. All piping within the condensing unit,evaporator, and interconnecting tubing should be checked for leaks. If a leak isdetected, the refrigerant should ...

15.0 FIELD INSTALLED ACCESSORIES 15.1 COMPRESSOR CRANKCASE HEAT (CCH) While scroll compressors usually do not require crankcase heaters, there areinstances when a heater should be added. Refrigerant migration during the off cyclecan result in a noisy start up. Add a crankcase heater to minimize refr...

18 15.4 HIGH AND LOW PRESSURE CONTROLS (HPC & LPC) These controls keep the compressor from operating in pressure ranges which cancause damage to the compressor. Both controls are in the low voltage control cir-cuit. High pressure control (HPC) is an auto-reset which opens near 610 PSIG andcloses...
