28 DRAIN P AN V AL VE During the cooling mode of operation, condensate which collects in the drain pan is picked up by the condenser fan blade and sprayed onto the condenser coil. This assists in cooling the refrigerant plus evaporating the water . During the heating mode of operation, it is necessary that water be removed to prevent it from freezi[...]

30 R efrigerant Char ging Proper refrigerant charge is essential to proper unit opera- tion. Operating a unit with an improper refrigerant charge will result in reduced performance (capacity) and/or effi ciency . Accordingly , the use of proper charging methods during ser- vicing will insure that the unit is functioning as designed and that its co[...]

31 3. Install a process tube to sealed system. 4. Make necessary repairs to system. 5. Evacuate system to 200 microns or less. 6. Weigh in refrigerant with the property quantity of R-410A refrigerant. 7. Start unit, and verify performance. 8. Crimp the process tube and solder the end shut. Proper safety procedures must be followed, and proper prote[...]

32 Ov erchar ged R efriger ant Systems After the unit has run 10 to 15 minutes, check the gauge pressures. Gauges connected to system with an undercharge will have low head pressures and substantially low suction pressures. Improper air fl ow over the evaporator coil may indicate some of the same symptoms as an over charged system. An overcharge c[...]

METERING DEVICE Capillar y T ube Systems All units are equipped with capillary tube metering devices. Checking for restricted capillary tubes. 1. Connect pressure gauges to unit. 2. Start the unit in the cooling mode. If after a few minutes of operation the pressures are normal, the check valve and the cooling capillary are not restricted. 3. Switc[...]

NOTE: System operating pressures must be near normal before valve can shift . REVERSING V AL VE DESCRIPTION/OPERA TION The Reversing V alve controls the direction of refrigerant fl ow to the indoor and outdoor coils. It consists of a pressure- operated, main valve and a pilot valve actuated by a solenoid plunger . The solenoid is energized during [...]

Reversing V alve in Heating Mode When sluggish or stuck in the mid-position, part of the discharge gas from the compressor is directed back to the suction side, resulting in excessively high suction pressure. Should the valve fail to shift from coooling to heating, block the air fl ow through the outdoor coil and allow the discharge pressure to bu[...]

8. Pressurize sealed system with a combination of R-22 and nitrogen and check for leaks, using a suitable leak detector . Recover refrigerant per EP A guidelines. 9. Once the sealed system is leak free, install solenoid coil on new valve and charge the sealed system by weighing in the proper amount and type of refrigerant as shown on rating plate. [...]

Exter nal Over load With power off, remove the leads from compressor termi- nals. If the compressor is hot, allow the overload to cool before starting check. Using an ohmmeter , test continu- ity across the terminals of the external overload. If you do not have continuity; this indicates that the overload is open and must be replaced. Certain unit [...]

R ecommended pr ocedure for compr essor replacement 1. Be certain to perform all necessary electrical and refrigeration tests to be sure the compressor is actually defective before replacing. 2. Recover all refrigerant from the system though the process tubes. PROPER HANDLING OF RECOVERED REFRIGERANT ACCORDING T O EP A REGULA TIONS IS REQUIRED. Do [...]
