2. Foundation
(1). Select a solid and level surface foundation to install the compressor.
(2). There is no need to construct a base for screw air compressor since the vibration of it is
relatively small. However the site of placement must be flat and strong enough to support
the weight of the unit.
3. Cooling system
Install an air-cooled compressor in a well-ventilated area to avoid high temperature
shutdown. If it is in a sealed room, air extracting and removal apparatus in required and
its capacity must be larger than cooling fan’s in compressor. In accordance with (Figure:
2-1) please select proper ventilating equipment for use.
Electrical
A qualified electrician in compliance with standards and local codes should do all electrical
wiring. Be sure to investigate the local requirements before installing the compressor. Refer to
the wiring diagram before starting any work.
The power supply should be adequate and free of parasitic loads that will cause an under voltage
condition during the operation of the compressor, otherwise there will be nuisance electrical
shutdowns. This equipment requires a properly grounded electrical disconnect switch.
We recommend the use of time delay fuses in a fusible disconnect for isolating the unit. This
disconnect should be located so an operator can disconnect the unit without nearing the unit, in
case of an emergency. We also recommend the use of a lockout/tagout to help insure safety
during maintenance of the compressor. Per the National Electric Code the time delay fuses
should be sized at 175% of the full load amperage (FLA) found on the motor nameplate. Consult
the Code if you want to use another style of branch circuit protection.
