"ROTATION" button on the touchscreen, there is
a 5 second delay before the pump will start for a
brief amount of time. Pump rotation should be
counterclockwise when looking at the rear of the
motor. Directional arrows are located on each
pump.
If the pumps are rotating in the wrong direction,
rotation can be reversed by switching any two
main power leads to the panel. Correct rotation
should be confirmed in the previous manner.
Repeat the process of switching the Unit printed
circuit boards from the manual override "OFF "
position to the default "AUTOMATIC" position
and testing rotation.
3A.3 Initial Operation
Start each pump by pressing "AUTOMATIC" on
the touchscreen. See Figure 3A.6.
WARNING:
Pumps that have
temperature may have a high surface
temperature on the top of the exhaust
muffler.
DO NOT TOUCH!

3A.3.1 Testing the Pumps
Run the pump for two minutes in the correct
rotation. Stop the pump and check that the gear
box is at the correct oil level, as shown in the
sight glass (See Figure 6.1 under Maintenance
Section 6). See Section 6.1.3 under Maintenance
for the oil type and quantity. DO NOT OPEN THE
FILLER PORT WHILE THE PUMP IS RUNNING.
After testing each pump, if everything appears
normal, put each pump into the "AUTOMATIC"
mode and allow each pump to run until vacuum
builds. Check for any leaks in the piping. Repair
leaks, if needed.
3A.3.2 Automatic Purge Operation
The system inlet piping contains an auto-purge
at each pump consisting of an isolation valve
and a purge valve. The purge system is used to
reduce the effect of corrosive gas.
When vacuum demand is satisfied, the control
panel system begins the purge process. The
vacuum pump continues to operate, the electric
actuator closes the isolation valve, and the purge
solenoid valve opens, allowing fresh air to enter
the vacuum pump. This purge process runs for
7 minutes (default setting). After the set purge
time completes the purge valve will close and
the pump will turn off.
