● Draining the Condensate
At the end of the day, turn off the main power supply and open the condensate drain valve to remove
the accumulated moisture from the air receiver. If the air compressor operates 24 hours a day, remove
the condensate once per day.
● Inspection and Cleaning
Make sure that there is no dirt and/or clogging of the intake air filters and that no accumulation of dust
has occurred around and inside the package.
● Excessive Vibration and Noise
If there is excessive vibration and/or noise, please verify the possible conditions in the table below.
● Check Valve Inspection
Stop the air compressor to inspect the check valve. If the air compressor reverse rotates for 3 seconds
or longer when it stops, the check valve is leaking and should be replaced. Contact the local Sullair
distributor for replacement.
● Safety Relief Valve Inspection
Open the front door of the air compressor and verify that the safety relief valve is operating properly
by lightly pulling the spindle of the safety relief valve when the air compressor is near maximum
pressure [122psig (8.4 bar) or 145psig (10.0 bar)]. Make sure that the safety relief valve does not
operate below the maximum pressure.
Possible Consequence Corrective Action
The transport fixtures (shipping bolt and
fixture) have not been removed.
Remove the transport fixtures. (Refer to page 4)
There is a gap between the base of the
air compressor and the ground.
Insert the attached rubber vibration isolator pads to
eliminate the gap (Refer to page 6).
Loose bolts and screws. Re-tighten any loose bolts and screws.
Any moving components have come in
contact with other components.
Contact the local Sullair distributor.
Scroll head and/or electric motor have
excessive viblation and/or sound.
The installation area cannot handle the
weight load of the air compressor.
Relocate the air compressor to an area that can
sufficiently handle the weight load or strengthen the
existing installation area.
The rubber vibration isolators have
deteriorated.
Replace the rubber vibration isolators as shown in the
figure below or contact the local Sullair distributor.
Check Valve has failed.
Replace the check valve or contact the local Sullair
distributor.
Abnormal noise from V-belt. Contact the local Sullair distributor.

● When it is time to replace the Rubber Vibration Isolators,
please contact local Sullair distributor to replace
all of the rubber vibration isolators at the same time.

● The safety relief valve is an important safety device that prevents the over-pressurization of the air
compressor and damage to the air compressor components. To prevent damage of these
components and/or accidents, carefully inspect the operation of the safety relief valve.
● When checking the functionality of the safety relief valve, a loud noise may occur during discharge.
Prepare for the discharge noise by wearing earplugs in order to prevent a personal injury. It is also
possible that dust may be dispersed by the discharged air, so ensure that protection glasses are worn.
● Contact the local Sullair distributor if the safety relief valve needs to be adjusted.
