INSTALLATION
Your JUN-AIR compressor is easy to operate. Observe the
instructions and you will get many years service from your
compressor.
• Visually inspect unit for shipping damage, contact your supplier
immediately if you think the unit may have been damaged.
• Check that the performance of the compressor matches the
actual air consumption, please refer to Technical Specifications.
• Check that the rating plate of the compressor corresponds with
the electrical voltage offered and check that fusing is adequate.
Placing
Place the compressor in a dust-free, dry and cool, yet frost-free room.
Sufficient cooling from the surroundings is important.
• Ambient temperature: 0°C to 40°C, 32°F to 104°F
• Relative humidity: Max 90%
Mount the two distance bolts (1) on the back of the cabinet to ensure
sufficient ventilation.
Installation
• Mount the drain bottle (2) visibly outside the cabinet and mount
the hose at the back of the cabinet (3).
• Connect the cable at the back of the cabinet (5).
• Plug the compressor into a standard outlet switch.
• Connect equipment at the back of the cabinet (4).
• The front wheels are delivered with brakes. Brake the wheels
before starting the compressor (6).
Thermo Switch
The fans are controlled by a Stego thermo switch adjusted to 30°C
from the factory – do not alter this setting. Check that the setting is
correct and adjust if necessary.
The fans will start when the temperature inside the cabinet exceeds
30°C and will run continuously until the temperature drops below
30°C.

OPERATION
• If the compressor has been stored at an extremely low
temperature, allow it to heat to room temperature before
switching it on.
• The cut-in and cut-out pressure is preset from the factory and
it is normally not necessary to change this. However, if it is
necessary to change the preset settings, the instructions of this
manual shall be followed carefully.
• All AC compressors are designed for 100% duty, but 50%
operation is recommended to prolong the lifetime.
• The fans on the back of the cabinet will start when the
temperature exceeds 30°C. It will run continuously even if the
compressor may have switched of until the temperature is below
30°C again.
• Do not lubricate the oil-less motor with oil, as it will destroy
important components.
Start
Start the compressor by pressing the green button.
The green lamp for compressor in operation is now
alight.
Read the outlet pressure on the pressure gauge.
Adjust the pressure on the regulator.
Read the receiver pressure on the pressure gauge.
The green lamp is alight when the fans are in operation.
Read on the hour counter the elapsed service time.
If the compressor does not start, there might be pressure in
the receiver. The compressor will automatically start when the
pressure drops.
The compressor will automatically stop when the preset cut-out
pressure is reached.
Stop
Turn off the compressor by pushing the green button.
The green light for compressor in operation switches off.

MAINTENANCE
To ensure a long lifetime of the compressor, it is important that
inspection and maintenance is carried out regularly as described in
the following.
Read the elapsed operation time on the hour counter.
Opening of cabinet
Turn the four () locks clockwise with a screwdriver or sim. to
open the cabinet.

CAUTION
Risk of Bursting
Open door to access drain assembly.
If drain bottle is installed, empty when necessary. ().
) Drain condensate by opening the manual drain on the receiver.
If mounted with auto drain, condensate will be drained
automatically.
b) Check outlet filter
Check and change the filter and filter element in accordance with
the instructions in ”Installation and maintenance instructions” for
the filter in question.
c) Check for leaks
Check motor, hoses and equipment for leaks. Check the pumping
time.
d) Clean the unit
Clean the unit when needed with a soft, damp cloth. If necessary,
use paraffin to remove adhesions. Dust and dirt prevent cooling.
e) Check safety valve
Check the safety valve with pressure in the receiver. The safety valve
is operated by pulling the ring (1) or turning the screw (2) depending
on the valve type.
f) Check intake filter
Check the intake filter and change it if necessary.
g) Check the non-return valve
Turn off the compressor on the mains switch and pull out the
plug.
Empty the receiver for compressed air by operating the safety
valve. When the receiver is empty, the reading of the pressure
gauge is bar.
Dismount the non-return valve from the receiver.

Disassemble the non-return valve and remove the O-ring () part
no. from the piston.
Clean the non-return valve.
Mount a new O-ring and re-assemble the non-return valve.
Re-install the non-return valve.
h) Check the fans
Check that the fans at the back of the cabinet work. They
will start when the temperature exceeds °C and will run
continuously until the temperature falls below °C.
i) Check dryer
If a dryer is installed refer to the operating manual for the dryer.
Please note that all service must be carried out by a qualified
person.
Adjustment of pressure switch
The working presure has ben preset from the factory, and it is
normally not necessary to change this.
However, if it is necessary to change the preset settings, the
instructions mentioned below should be followed carefully.
Warning
The compressor is constructed and approved for a max.
pressure as stated under Technical Specifications - do not
adjust to a higher pressure.
Higher working pressure will reduce the lifetime of the
compressor.
The compressor will stop at max. pressure (stop pressure) and
start again at min. pressure (start pressure). The difference
between max. and min. pressure is the differens pressure.
Unscrew the lid of the pressure switch. Adjust max. pressure
adjusting the two springs marked A (clockwise: higher pressure).
Adjust the two springs identically.
Adjust the differens pressure adjusting the spring marked B
(clockwise: higher differens pressure, start pressure maintained).
Test of pumping time
The pumping time indicates the condition of the compressor.
. Check that there are no leaks in the system.
. Empty the air receiver of compressed air so that the
pressure gauge shows bar.
. Close the filter regulator and check that the drain valve is
closed.
. Start the compressor and note the time it takes until it is
turned off again by the pressure switch. Check that the
pumping time agrees with the technical specifications for
the actual compressor system.
Please note that the pumping time in this manual is given for to
max pressure. Deviations from this result in deviating results.
Important
Always test the pumping time when cold. If the compressor is
warm, the pumping time will be considerably longer.
FAULT FINDING AND REPAIR
Important
Switch off and isolate from electrical supply before removing
any parts from the pump. Empty air receiver of air before
performing any operation on the compressors’ pressure
system.
1. Compressor does not start
a. The air receiver is pressurized. The motor will start when
the pressure has dropped to the preset start pressure.
Empty the receiver.
b. Check that the mains supply agrees with the motor
label.
c. No power from mains. Check fuses and plug.
d. Bad connection or broken cable.
e. The motor is overheated and the thermal protection
has switched it off. When cooled the motor will turn on
automatically. Go to section .
f. The compressor has not been unloaded and there
is back pressure on the piston. Ensure that the
compressor is unloaded each time it stops.
g. The motor is blocked.
h. Defective capacitor.
2. The compressor makes a buzzing sound but does not start
a. Leaky non-return valve. Dismount the pressure pipe and
check if air leaks from the non-return valve. Clean and
replace.
b. The motor is blocked.

3. The compressor runs but the pressure does not increase
a. Intake filter clogged. Replace.
b. Non-return valve is clocked. Clean or replace.
c. Leaks in fittings, tubes or pneumatic equipment. Check
with soapy water or by letting unit stay over night
disconnected from mains. Pressure drop should not
exceed bar.
d. Check the piston gaskets. Replace if necessary.
e. Defective valve plate. Contact your JUN-AIR distributor.
4. The motor gets very hot
a. The ambient temperature is too high. If the motor is
installed in a cabinet, sufficient ventilation must be
ensured.
b. Leaks in fittings, tubes or pneumatic equipment. Check
with soapy water or by letting unit stay over night
disconnected from mains. Pressure drop should not
exceed bar.
c. The compressor is overloaded.
5. The compressor runs even if no air is tapped
a. Leaks in fittings, tubes or pneumatic equipment. Check
with soapy water or by letting unit stay over night
disconnected from mains. Pressure drop should not
exceed bar.
6. The compressor does not start at min pressure or does not
stop at max pressure.
a. Defective pressure switch. Replace.
