Specifications

1. Inspect the ProVax thoroughly to insure that
it is in good operating condition.
2. Ensure that the outlet valve/knob (RED) and the
inlet valve/knob (BLUE) on the ProVax are in
the closed positions.
3. Set the "Mode" valve/knob (Yellow) to “Recovery”
4. Set the "Recover/Purge" valve/knob (BLACK)
to "Recover".
5. Connect ProVax to the system being serviced,
making sure all connections are correct and
tight. (see set-up diagram).
6. Open the liquid port of the recovery cylinder
(always open valves slowly to check hoses and
connections for leaks).
7. Open the liquid port on your manifold gauge set.
Opening the liquid port will remove the liquid
from the system first, greatly reducing the recov-
ery time. (after the liquid has been removed,
open the manifold vapor port to finish evacuating
the system).
Note: The ProVax uses an "oil-less" compressor
during recovery. It is lubricated with the oil suspend-
ed in the refrigerant. Ensure there is refrigerant up
to the ProVax inlet valve prior to turning on the unit.
8. Connect your ProVax to Power.
9. Place "High Pressure Shut Off Select”
switch in the desired position.
Note: When the High Pressure Select switch is in
the ON position, the unit will shut off at 550 PSI
(for R410A). In the OFF position it will shut off at 400
PSI.
a. Turn on the "Power" switch. You should hear
the cooling fans running
b. Press the "Start" switch. This momentary
switch will start the compressor/motor.
10. Open the output valve/knob (RED) on the
ProVax.
11. Slowly open the input valve/knob (BLUE) on the
ProVax.
a. If the compressor starts to knock, slowly
throttle back the input valve/knob until the
knocking stops.
b. If the input valve was throttled back, it should
be fully opened once the liquid has been
removed from the system (the manifold
gauge set vapor port should also be opened
at this time).
12. The ProVax will automatically stop after the
refrigerant has been removed and it reaches
10” to 20" hg vacuum.
Note: Anytime you want to pause an operation, you
can stop the unit by turning the "MODE" valve/knob
(YELLOW) to “Stop”.
Note: To restart, turn the Recover/Purge valve/knob
(BLACK) to “Recover” and the input valve/knob
(BLUE) to “Closed” and press the “Start” switch.
13. Close the manifold gauge set’s vapor and
liquid ports.
14. Turn the ProVax input valve/knob (BLUE) to
the “Closed” position.
15. Proceed with the Self Purge and Vacuum.
(see Self Purge/Vacuum procedure
on page 12).
Note: Always purge the ProVax after each
use. Failure to purge the remaining refrigerant from
the ProVax could result in the acidic degradation
of internal components, ultimately causing
premature failure of the unit.
