Continue to operate until the LP gauge indicates the required vacuum has been
obtained�
11
Turn off the F6-DP and close the INLET valve (V1) — Wait five minutes�
If the MANIFOLD gauge indicates pressure has risen above 0 PSIG (0 bar), refrigerant is
still present�
• Open the INLET valve (V1) and turn on F6-DP.
• Run the F6-DP until the required vacuum is reached again.
• Wait five minutes. Repeat this process until all refrigerant is removed and
pressure is 0 PSIG (0 bar), or less.
12
Immediately purge the F6-DP� Purging is necessary to remove any residual
refrigerant from inside the F6-DP internal components as well as the hose from
the outlet to the recovery tank� Refer to
Purging the F6-DP
and
Figure 2
below�
PURGING F6-DP
1
While the F6-DP is off, rotate the PURGE/RECOVER valve (V2) to PURGE�
See
(See Figure 2).
2
Turn on the F6-DP and slowly rotate the INLET valve (V1) to PURGE�
3
Run the F6-DP and monitor the LP gauge until a vacuum of 20 In/Hg (0�7 bar)
or more is achieved�
4
Turn off the F6-DP and immediately close the valves on the recovery tank�
Rotate the inlet valve (V1) to CLOSE�
The hose and the discharge port will contain a small amount of pressurized refrigerant�
Exercise care when removing this hose�
