1. Ensure that a properly sized air receiver is installed [80 gallons (303 liters) or more]. Without a properly
sized air receiver, it is possible that the air compressor can be damaged due to excessive starts and stops.
2. Use a textile reinforced, heat resistant rubber hose (hydraulic) of appropriate rating (see page S-2) to
connect the Oil Free Scroll Air Compressor to the air receiver.
■ It is necessary to install a properly sized air receiver to this compressor in order to reduce excessive
starts and stops.
■ Without a properly sized air receiver, it is possible that the main motor or electromagnetic contactor may
receive unwarranted wear due to excessive starts and stops.

● Use a heat resistant, pressure tight rubber hose (see page S-2) to connect the Oil Free Scroll Air
Compressor to the air receiver. The rubber hose will prevent damage to the air receiver due to vibration.
● Use of an improper rubber hose may lead to cracks and/or leaks due to hose deterioration.
● Do not operate the air compressor when the stop valve between the air receiver and the air
compressor is closed.
● Do not install heavy objects, such as drain traps and filters, to the compressed air discharge as they
may damage the discharge line of the air compressor.
● If a remote vertical air receiver is installed, attach the air receiver to the ground with foundation bolts.
WARNING
4 Piping the Air Compressor
Safety Relief Valve
● If a stop valve is installed
in the middle of the
compressed air piping,
install a safety relief valve
between the air
compressor and the stop
valve.
Vertical Air Receiver
● To avoid damage to the air
compressor due to excessive
starts and stops, a properly sized
air receiver must be installed.
Hose Fitting
Rubber Hose
● A textile reinforced, heat
resistant rubber hose
(hydraulic)(see page S-2)
is recommended to
connect the equipment.
Stop Valve
● Make sure to install a
stop valve between the air
compressor and the air
receiver.
Installation(continued)
● Without a properly sized air receiver, it is possible that a serious accident may occur due to the
unwarranted wear of the main motor or electromagnetic contactor.
● For the protection of the air compressor, if excessive starts and stops occur the compressor will
shut off and display cycle error [E.CY]. This will stop the supply of compressed air.
● The error message cycle error [E.CY] is an indication that the volume of air receiver is insufficient
for proper operation. An increase in the volume of the air receiver will eliminate the cycle error [E.CY].
