OPERATING YOUR PROMAX
READ THIS ENTIRE SECTION BEFORE ATTEMPTING TO CONNECT OR USE
YOUR RECOVERY MACHINE. ENSURE THAT YOU FULLY UNDERSTAND THE
ACTIONS AND THEIR ORDER BEFORE BEGINNING THE PROCESS!!
Procedure for Normal System Recovery
Make certain that 0 or negative pressure is shown on both blue and red gauges
before proceeding with use!!
1. Inspect the PROMAX unit thoroughly to ensure that it is in good operating
condition.
2. Ensure that both the Inlet and Outlet valves on the front panel are closed.
3. Make sure the Recover/Purge valve is set on Recover. Applies only to a Promax
MiniMax-E, RG 5410A-E or RG 6-E.
4. Make sure all connections are correct and tight.
5. Slowly open the liquid port of the recovery cylinder (always open valves slowly to
check hoses and connections for leaks) and ensure that there are no leaks
detectable.
6. Ensure that the Vacuum Low pressure switch is in OFF position AND remains
OFF while unit is used. Applies only to a Promax RG 5410A-E or RG 6-E.
7. Connect your Promax to main power supply.
8. Switch the main power switch to the ON position. You should hear the fan running.
Note: Allow the fan to run for 60 seconds.
9. Press the compressor start switch. This "momentary" switch will start the
compressor.
10. Open the Outlet port of the PROMAX unit.
11. Open the liquid port on the manifold gauge set; opening the liquid port will remove
the liquid from the system first, greatly reducing the recovery time (after the liquid
has been removed, open the manifold vapor port to finish evacuating the system).
12.Slowly open the input port on the PROMAX unit.
a) If the compressor starts to knock, slowly throttle back the input valve
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 vapour port
should also be opened at this time).
Bosch Automotive Service Solutions GmbH declines all responsibilities or claims
when Promax units are used improperly or not according all recommended/mentioned guidelines.
