Operating Instructions
Installation (Continued)
PIPING
Never use plastic (PVC) pipe for compressed air.
Serious injury or death could result.
Any tube, pipe or hose connected to the unit must be able to
withstand the temperature generated and retain the pressure. All
pressurized components of the air system must have a pressure
rating of 200 psi or higher. Incorrect selection and installation
of any tube, pipe or hose could result in bursting and injury.
Connect piping system to tank using the same size fitting as the
discharge port.
INSTALLING A SHUT-OFF VALVE
A shut-off valve should be installed on the discharge port of the
tank to control the air flow out of the tank. The valve should be
located between the tank and the piping system.
Never install a shut-off valve between the
compressor pump and the tank. Personal injury
and/or equipment damage may occur. Never use reducers in discharge
piping.
When creating a permanently installed system to distribute
compressed air, find the total length of the system and select
pipe size from the chart. Bury underground lines below the
frost line and avoid pockets where condensation can gather and
freeze.
Apply air pressure to the piping installation and make sure
all joints are free from leaks BEFORE underground lines are
covered. Before putting the compressor into service, find and
repair all leaks in the piping, fittings and connections.
