21 The V ert-I-Pak A series units must be installed with a free return air configuration. The table below lists the indoor airflow at corresponding static pressures. All units are rarted at low speed. The V ert-I-Pak units are designed for either single speed or two fan speed operation.
CAP ACIT ORS ELECTRIC SHOCK HAZARD W ARNING T urn off electric power before servicing. Discharge capacitor with a 20,000 Ohm 2 W att resistor before handling.
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.
A good understanding of the basic operation of the refrigeration system is essential for the service technician. Without this understanding, accurate troubleshooting of refrigeration system problems will be more difcult and time consuming, if not (in some cases) entirely impossible.
CUT/SEVER HAZARD W ARNING Be careful with the sharp edges and corners. Wear protective clothing and gloves, etc. Failure to do so could result in serious injury . ELECTRIC SHOCK HAZARD W ARNING T urn off electric power before service or installation.
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 efciency .
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-22 refrigerant. 7. Start unit, and verify performance. 8. Crimp the process tube and solder the end shut.
An undercharged system will result in poor performance (low pressures, etc.) in both the heating and cooling cycle. Whenever you service a unit with an undercharge of refrigerant, always suspect a leak.
T roubleshooting a restricted refrigerant system can be difcult. The following procedures are the more common problems and solutions to these problems. There are two types of refrigerant restrictions: Partial restrictions and complete restrictions.
30 All units are equipped with capillary tube metering devices. Checking for restricted capillary tubes. 1. Connect pressure gauges to unit.
31 NOTE: System operating pressures must be near normal before valve can shift . The Reversing V alve controls the direction of refrigerant ow to the indoor and outdoor coils.
32 Reversing V alve in Heating Mode The solenoid coil is an electromagnetic type coil mounted on the reversing valve and is energized during the operation of the compressor in the heating cycle. 1. T urn of f high voltage electrical power to unit.
33 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.
34 Locked rotor voltage (L.R.V .) is the actual voltage available at the compressor under a stalled condition. Disconnect power from unit.
35 Remove the leads from the compressor terminals and set the ohmmeter on the lowest scale (R x 1). T ouch the leads of the ohmmeter from terminals common to start (“C” to “S”).
36 1. Be certain to perform all necessary electrical and refrigeration tests to be sure the compressor is actually defective before replacing.

38 R OUTINE MAINTENANCE AIR FIL TER Clean the unit air intake lter at least every 300 to 350 hours of operation. Clean the lters with a mild detergent in warm water and allow to dry thoroughly before reinstalling. Units are to be inspected and serviced by qualied service personnel only .
SLEEVE / DRAIN Inspect the sleeve and drain system periodically (at least yearly or bi-yearly) and clean of all obstructions and debris. Clean both areas with an antibacterial and antifungal cleaner . Rinse both items thoroughly with water and ensure that the drain outlets are operating correctly .
