Read and follow
all warnings at the beginning of this
manual before operating the unit.
Use only with refrigerant type R-134a!
Cross-contamination with other refriger-
ant types will cause severe damage to the
station and to tools and equipment.
Do not mix refrigerant types through a
system or in the same container!
1. Attach the station’s yellow charging
hose to a full refrigerant tank, as
follows:
•Disposable tanks — Connect the
yellow hose, open the tank’s valve,
and place the inverted tank (with its
valve down) on the scale platform.
Be sure to center the tank over the
stud welding point. Use only tanks
designed for use with R-134a, includ-
ing Acme threads on the fittings.
5. Plug the station into the proper
voltage outlet, and turn on the MAIN
POWER switch.
6. Simultaneously press the ENTER
and zero keys on the keypad to access
the manual diagnostic mode.
7. Press “1” on the keypad to start the
pump.
8. While the pump is running, add
enough vacuum pump oil so that the
oil level is even with the line on the
reservoir’s sight glass.
9. Press “1” or the RESET CYCLE key
on the keypad to stop the pump.
10. Replace the black plug on the oil fill
port.
IMPORTANT! For maximum perfor-
mance, change the vacuum pump oil
frequently (approximately after every
four hours of running time). We recom-
mend using our Premium High Vacuum
Pump Oil; it is specifically blended to
maintain maximum viscosity at normal
running temperatures and to improve
cold weather starts (see the “Replace-
ment Parts List”).
Read and follow the detailed instructions
in the Vacu-Master
® Vacuum Pump
Operating Manual. You do not need to
return the warranty registration card
contained in the Vacu-Master
® Vacuum
Pump Operating Manual — return only
the warranty registration card attached
to the station to validate your warranty.
