Installation
1.
Do not install outside.
2.
The compressor system must be located in a clean,
well lit and well-ventilated area.
3.
The area should be free of excessive dust, toxic or
flammable gases and moisture.
4.
Never install the system where the surrounding
temperature is higher than 104°F or where
humidity is high.
5.
Clearance must allow for safe, effective inspection
and maintenance.
6.
Install the compressor on a level floor. If necessary,
use metal shims or leveling pads to level the
system. Never use wood to shim the unit. Unlevel
floor may cause vibration, noise, or failure of the
compressor.
7.
Do not block the air compressor intake or exhaust
grating.
NOTE:
Minimum of 36 in. of clearance is recommended
on all sides. Minimum recommended distance
between the top of the compressor and the ceiling is
48 in.
Piping
1.
The drain pipes, from five drain outlets on the right
side of the compressor, to the drain collector, must
not be restricted. Do not allow the pipe outlet to
extend into the accumulated water in whatever
container is used.
Discharged drain may
contain oil. Condensate
disposal methods must account for conditions where
some oil mist from the gearbox ventilation system is
contained in the condensate.
2.
When determining the diameter and the length of
compressed air outlet pipes, consider the pressure
drop and allow for the possible expansion of piping
network in the future. Avoid sharp bends. Keep
pressure drop to less than 1.5 psi. Refer to pipe
sizing charts as needed.
3.
When installing branch pipes, make sure the pipes
are connected to the top side of the main pipes in
order not to let condensation water in the branch
pipes.
4.
The main pipe shall have about 1/100 downward
slope away from the compressor to the end. When
encountering a U-shaped bend in piping and rising
piping, be sure to install a drip leg and drain valve
at the bottom.
5.
Install the air receiver after setting up the
compressor. Do not place check valves or filters,
other than water separators, between the
compressor and the air receiver.
6.
If you install an air dryer, install it after the air
receiver.
As the compressor is
regulated by load/unload
system, always install an air receiver.
Using an undersized air receiver will increase the use of
electricity and will decrease the product life. The
minimum size requirement of air receiver is
240 gal
for
model PCC500.
For the pipe connection of the compressor, the flange
or union connection is recommended for easier
maintenance.
When connecting outlet pipes to the
compressor use a union to facilitate maintenance in the
future. An isolation valve may be installed, make sure
it is open when the compressor is in use. Do not install
a check valve between the compressor unit and the air
receiver/tank.
