Remote System Evacuation/Re-charge

All field repairs to the sealed system must start with a total dis-

charge 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 - flaker receiver outlet valve

Point #2 - flaker high side service valve

Point #3 - flaker low side service valve

Evacuation:

1. With flaker power supply turned “OFF” disconnect and insu-

late 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 solenoid 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 nor-

mal 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 flaker power switch OFF. Reconnect compressor leads.
