Operation(continued)
● During inspection of the safety relief valve, a loud noise will be emitted from it, Therefore, prepare
for the noise in order to prevent personal injury.
● If there is excessive vibration or abnormal sound, please refer to page 25 for adjustment.
● If the air compressor is not operating and the discharge stop valve is closed, the pressure indication
on the digital display may lower, which is due to a decrease in temperature. This is normal.
● Turn off the power in the case of a power failure or electric storm to prevent damage to the air
compressor and/or personal injury.
① Close the front door and fully open the
discharge stop valve.
3 Start Up
(Please contact the local Sullair distributor for start up.)
② Check the earth leakage (ground) circuit
breaker to make sure it is ON. Turn ON
the main power supply to the air
compressor.
⑦ Open the discharge stop valve to lower the
pressure and verify that the air compressor
restarts at the load pressure setting.
⑤ Close the stop valve on the air receiver
and verify that the operation of the air
compressor stops when the maximum
pressure is reached (under pressure
control mode).
During operation of Multi-Drive control
mode, the SRL compressor heads will stop
one after another, and maximum pressure
will not be reached. This is not a failure.
⑥ Slightly pull the spindle of the safety relief valve
when the air compressor is near maximum
pressure.

④ Verify that the rotating direction of the
main electric motor is clockwise when
viewed from the front as shown in the
diagram below.
Rotating
Direction
7.5/11MB6 16.5MB6
Note: It is normal that the operation of the
air compressor restarts at a pressure
higher than the recovery pressure under
Multi-Drive control mode.
