PUMP DOWN

PERATIONS

The Model 3600-R410A is equipped with a pump-down purge valve that allows the

technician to pump down or evacuate the 3600-R410A before proceeding to the next

recovery operation. This procedure not only eliminates cross contamination, but also

conserves refrigerant. Follow the steps below to ensure your pump down operation is

performed correctly.

STEPS:

1. After recovery operations are complete and the system switch is in the OFF position:

FIRST - Place the inlet valve in the PURGE position

SECOND - Place the purge valve in the PURGE position

THIRD - Place the outlet valve in the OPEN position as illustrated below.

It is important to turn the valves in this order to ensure the compressor properly

equalizes.

2. Turn the system switch to the “ON” position. The LED status will be green.

NOTE: If the compressor fails to start, cycle the purge valve

from the RECOVERY to

PURGE position to reduce the pressure difference shown on the system’s gauges.

3. Allow the unit to run until it shuts off automatically. The status display will flash

“EVACUATION COMPLETE” indicating that the purge operation is complete.

4. Turn the system switch to the OFF position and turn the outlet valve to the “CLOSE”

position. Close the inlet and outlet valves on the DOT recovery tank.

During the pump down operation, the 3600-R410A’s compressor pulls the entire system

and discharge hose into a vacuum and discharges the gas directly out of the discharge port

leaving no more than 1/4 ounce of refrigerant left in the system.

CAUTION!: Never turn the purge valve when the unit is operating! Severe damage

may occur.
