REMOTE SYSTEM EVACUATION/RE-CHARGE

All field repairs to the sealed system must start with a total discharge of the system following the requirements of the Clean Air Act of July, 1992.

Proper evacuation of the total remote system will require a three (3) point hook-up of your manifold and hose set, (see drawing):

Point #1 - Cuber receiver outlet valve

Point #2 - Cuber high side service valve

Point #3 - Cuber low side service valve

Evacuation:

1.With cuber power supply turned “OFF” disconnect and insulate all 3 compressor leads at the compressor. Turn power supply on, place power switch in the “on” position. This will energize (open) the Liquid Line so- lenoid allowing evacuation of the Liquid Line between the solenoid and the expansion valve(s).

2.Evacuate system to 200/250 microns or less. At this point, there should be a holding test of five(5) minutes. You may expect a slight loss of vacuum as normal. A rapid rise to normal atmospheric pressure indicates moisture still present in the system. On a “wet” system, it will prove beneficial to use heat lamps to warm the compressor dome and evaporator surface during evacuation.

3.Turn cuber power switch OFF. Reconnect compressor leads.

4.*After proper evacuation hold test has been performed, the refrigerant charge should be “dumped” into the receiver until the pressure equalizes, stopping the flow. Do not try to throttle the refrigerant flow. Doing so will allow system pressure to balance too soon. The high-side service valve should be closed and the bal- ance of the charge fed slowly through the suction side service valve with the compressor operational. Con- trol the feed rate at no faster than four (4) ounces [113.g] per minute to ensure the compressor oil does not become too saturated with refrigerant resulting in a loss of compressor lubrication.

5.All refrigerant re-charging must be weighed into the system, utilizing an electronic charging scale. DO NOT attempt to recharge the system by sight glass, system pressure, amperage, frost line or sweat patterns.

6.Always leak check entire system after recharge.

CAUTION: Before programming the electronic scales to “dump” the charge, de-energize the liquid line solenoid, close the shut-off valve on vacuum pump and low side of the manifold set.
