ALL PUMPS:
Regular inspection, cleaning filters, and “flushing” may prevent extensive repairs. Dirty or clogged filter elements
can cause overheating (in excess of 200
°F) and possible pump failure.
It is normal for the pump surface and immediate output air temperatures to reach 200
°F when the unit is run
continuously under a heavy load or high pressure settings.
o
If there is evidence of overheating or excessive noise, stop immediately.
o
High-pressure operation will shorten pump’s life.
o
Keep external surfaces clean for proper heat dissipation.
o
Do not allow pump to operate in ambient air temperatures excess of 40
°C (104°F).
Failures due to pressure buildup are due to the following:
o
Improper setting of pressure relief valve
o
Leaks in airline connections
o
Damaged filter canister threads
o
Collapsed or kinked air lines, dirty filter elements
o
Vanes sticking in the rotor slots
ELECTRICAL MOTORS:
Some electrical motors are equipped with a thermal protector that shuts motor down automatically when subjected
to mechanical or electrical overloads. Ensure electrical power source corresponds to what is on the motor name
plate.
AIR DRIVEN MOTORS:
The air coming out of the discharge port will cool as it expands. It is important that the PVC extension (included
with the blower) is used to extend the muffler from the motor discharge port. This will help prevent ice from
forming on the muffler due to moisture in the air.
