CARE AND MAINTENANCE OF YOUR ProVax
TM
Use of a filter/dryer at the inlet is mandatory.
A filter/dryer must always be used between the
recovery machine and the inlet hose.We recommend
that a clean filter be used for every service job.
Failure to use a filter will invalidate your warranty.
The use of a filter will greatly reduce the risk of
damage to your ProVax, by preventing
foreign material from entering the unit.
Each filter should be labeled and used exclusively
for one type of refrigerant only.
Special care should be taken when recovering
from a "burned-out" system. Use two high acid
capacity filters, in series. (Alco type EK-162-F or
Sporlan type C-162-F are recommended )When
you have finished recovering from the system,
flush your ProVax with a small amount of clean
refrigerant and refrigerant oil to purge off any
foreign substances left in the unit.
Do not expose Vacuum Pump to pressure. It is
protected by a pressure cut-off switch set at 25 psi
(+/- 5).
Maximum vacuum level 13 in. Hg while in Recovery
mode. The compressor is protected by a low pres-
sure cut-out switch set at 13 in. Hg (+/- 3). Use
Vacuum mode to fully evacuate system.
Always empty refrigerant from the ProVax into a
storage tank; see Self-Purge procedure on Page 12.
Liquid refrigerant left in the ProVax’s condenser may
expand, causing damage to components.
If the unit is to be stored or not used for any length
of time, we recommend that it be complenty evacu-
ated of any residual refrigerant and purged with dry
nitrogen.
