EVACUATING PROCEDURE

1. Remove all refrigerant from the

system. NOTE: It is unlawful to

discharge or exhaust refrigerants into

the atmosphere. CPS strongly

recommends the practice of recovery

or recycling.

2. Connect a vacuum pump to the center

yellow charging hose.

3. Connect the high side service valve of

the system to the right side red

charging hose.

4. Connect the low side service valve of

the system to the left side blue hose.

5. Fully open the high and low side hand

knobs.

6. Start the vacuum pump.

7. Evacuate the system according to the

manufactuer's specifications; close the

high and low side hand knobs.

8. Turn off the vacuum pump.

9. Disconnect the yellow charging hose

at the vacuum pump end and connect

it to the refrigerant supply tank. (Make

sure to turn shut off valve, off before

disconnecting).

10.Slightly open the valve on the

refrigerant supply tank and purge the

air from the yellow hose at the

manifold by loosening the yellow hose

fitting, the close fitting and container

valve.

CHARGING PROCEDURE

1. Follow the manufacturer's

recommended specification for the

amount of refrigerant to charge in that

system. Should it specify to charge the

system on that high side, close the low

side service valve. Open the

refrigerant supply container valve,

then open the high side (red label)

hand knob of

the manifold. After the proper amount

of refrigerant has been transferred,

close the high red label hand knob of

the manifold; also close the

refrigerant supply container valve.

2. When the proper charge has been

achieved, open the low side service

valve on the system.

3. Run the compressor as per the

manufacturer's specifications and

observe the pressure gauge reading

and compare to the manufacturer's

specifications to determine that the

system is operating correctly. If no

adjustments need to be made, then

read step 4. If not, follow proper

procedures to repair or adjust the

system.

4. Close the high and low side service

valve of the system before removing

the charging hoses from the system.

Follow all safety practice procedures.

WARNING: Remove all hoses with care as

they may contain refrigerant.
