HOW TO OPERATE THE JUN-AIR COMPRESSOR

Your JUN-AIR compressor is very easy to operate. Observe the following simple
instructions and you will get many years' service from your compressor.
1. Visually inspect unit for shipping damage, contact your supplier immediately if
you think the unit may have been damaged.
2. Always keep the compressor in a vertical position during use and
transportation.
3. Place the compressor in a dustfree, dry and cool, yet frostfree, room. Do not
install in a closed cupboard, unless adequate openings for ventilation are
available (fig. 1). Ensure that the compressor stands firmly on the floor.
4. Replace the cap on the air intake tube with the intake filter (fig. 2).
5. Connect pneumatic equipment.
Important!
The compressor oil may be aggressive towards certain gasket
materials used in pneumatic equipment. We recommend Teflon,
Viton, etc.. Do not use polycarbonate filter bowls. Contact your
local JUN-AIR distributor if you need further information.
6. Plug the compressor into an outlet switch of nominal voltage and ensure that
fusing is adequate (see Technical Details).
7. Start the compressor using the 0/1 switch on the pressure switch (fig. 3). The
compressor will automatically switch off at the preset pressure. If the motor
does not start it may be due to pressure in the receiver, and the motor will then
start automatically when the pressure reduces to approx. 6 bar/87 psi.
8. Always keep the compressor in a vertical position as oil may run out of the
intake filter. During transportation, mount the cap on the inlet. Mechanical
noise from the compressor in connection with handling does not have any
functional importance.

Warning!

Never mount the transportation cap on oil-lubricated compressors
while there is still pressure in the compressor & pressure vessel,
as this may cause a pressure build up in the motor housing.
9. Adjustment of pressure (fig. 4):
A: Max. pressure adjustment (cut-out)
B: Differential adjustment (cut-in)
The cut-in pressure (normally 6 bar) is set by adjustment of differential screw
B. Turn clockwise to reduce cut-in pressure.
The cut-out pressure is set by even adjustment of the two screws A. (Cut-in
pressure + differential = cut-out pressure). Turn clockwise to increase cut-out
pressure.
The switch is normally factory set for operation at 6-8 bar (approx. 90-120
psi).
