The motor must be connected according to the electrical codes through a fused switch in order to protect the
motor against electrical or mechanical overload conditions. The overload of the motor starter must be set at a level
equal to the full load motor current listed on the motor nameplate.
If the compressor is supplied with a motor starter, it is preset at the factory according to customer specifications. It is
advisable to check that these settings are in line with the voltage at your location. If the voltage
is different, please contact
I.VA.CO.
for motor and starter information.
C
orrect direction of rotation is marked by an arrow on the motor fan housing and is counterclockwise when looking
at the motor from the motor's fan side.
After electrical connections have been made, the rotation of the motor should be checked. If backward,
reverse any two leads of the three at the power connection.
1. 1.5 Pressure Connections
Use a pipe size that is at least the size of the compressor inlet connections. Smaller lines result in a reduced
compressor capacity.
Compressors operating in parallel on a common main line should have a manual or automatic operated
shut-off valve or positive action check valve, installed in the suction line adjacent to the pump suction
flange. Remove the plastic protective cap from the discharge port prior to connection of compressor to the system.
Should process gas contain dust or other foreign particles, a suitable in line (inlet) filter should be connected to
the inlet port. Consult
I.VA.CO:. for r
ecommendations.

1.6 Oil Filling on Gear Box
The pump is shipped without oil in gear box. After level installation and correct rotation has been established,
fill the pump with recommended gear oil through the oil fill port. Oil level should be over 3/4 position on the
oil sight glass as shown on the label.
