Warning
·
Unless directions are followed and original spare parts
used, physical injury or property damage may result.
·
Protect compressor against rain, moisture, frost, and dust.
·
Compressor is only suitable for installations with the
nominal voltage stated on the motor plate.
·
The compressor is constructed and approved for a max.
pressure of 8 bar/120 psi. Do not adjust the compressor to a
higher pressure.
·
Do not in any way block or prevent the normal functioning of
the safety valve on the receiver.
·
Only connect pneumatic equipment suitable for the max.
pressure indicated.
·
Do not operate compressor at ambient temperatures
exceeding 35°C/95°F or falling below 0°C/32°F.
·
Do not touch compressor motor during operation as there is
a risk of burn due to high temperatures.
·
Do not direct air flow at head or body.
·
When a flammable liquid is sprayed, there may be danger of
fire or explosion, especially in closed rooms.
·
Always keep the compressor out of reach of children.

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.
Operating manual 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).
Technical details
The max. operation of the compressor is 50% of the operation
time, and the max. operation time is 15 min. at 8 bar/120 psi in
each cycle. Consequently, 15 min. standstill is required before
the next start. For tables with technical data and performance
curves, see page 15.
