Flash Recovery Procedure
WARNING
A guard MUST be placed over the pulley and belt if it is necessary to operate the compressor
without the cover.
WARNING
Severe burns and / or injury could occur from contact with hot surfaces. Several parts of the
compressor are hot during and after operation.
When the compressor has flashed, take the following steps to flush the system:
1
Flush air compressor and check for rotor grinding.
a) Remove 2-1/2” inlet hose from inlet valve.
b) Drain compressor oil.
c) Completely fill compressor air inlet with clean IMT specified oil. Once full, lower oil drain
hose into bucket and rotate compressor by hand to evacuate any remaining oil. Repeat
until oil is clean. Make sure the compressor turns freely by hand and that there is no
grinding present.
2
Flush oil cooler.
a) Remove both tubes from oil cooler.
b) Verify that the plastic shroud and fan blades are intact. Put power direct to red lead
(ground black lead) at fan motor to verify that motor works. Do not run the motor outside
of the shroud. Leave package assembled. Fan is a puller style; verify that air from fan
pulls air through the oil cooler from the outside.
c) Connect a hose to each of the inlet and outlet of the oil cooler.
d) Pour IMT compressor oil into lower port (note” hose will need to be higher than cooler).
Upper port hose should be drained into a bucket / pan.
e) Use low pressure (about 50 psi) air to remove all oil. Input air into the lower port.
f) Reconnect tubes (removed in 2a).
g) Fill with clean IMT approved oil. Reconnect all fittings and electrical terminals.
3
Start compressor.
a) Run for 5 minutes. Note operation, sound, check for leaks, etc.
b) Drain oil, change oil filter, fill oil to proper level, and finish testing.
