JUN-AIR i Series - Manuel

INSTALLATION
Your JUN-AIR compressor unit 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.
Mount inlet filter
Check that the performance of the compressor matches
the actual air consumption
Check that the rating label of the compressor corresponds
with the electrical voltage offered and check that fusing is
adequate.
Start the compressor using the 0/1 switch on the pressure
switch
Placing
Place the compressor in a dustfree, dry and cool, yet
frostfree room.
Sufficient cooling from the surroundings is important.
Ambient temperature: 0°C - 40°C, 32°F - 104°F
Relative humidity: Max 90%
OPERATION
If the compressor has been stored at an extremely low
temperature, allow it to heat to room temperature before
switching it on.
Do not use motor for compression of liquids and dangerous
gasses, such as petrol vapour and solvents.
The cut-in and cut-out pressure is preset from the factory.
All compressors are designed for 100% duty but 50%
operation is recommended to prolong the lifetime.
Do not lubricate the oil-less motor with oil, as it will destroy
important components.

Receiver
Turn the outlet valve counterclock wise one quater of a
turn. Sound will occur.
b) Check filter at filter regulator
Check and change the filter element.
c) Check for leaks

Check the intake filter and change filter element if
necessary.
g) Check non-return valves
Turn off the compressor on the main switch and pull out the
plug.
Empty the receiver for compressed air by operating the
safety valve. WARNING loud noise. When the receiver is
empty, the reading of the pressure gauge is 0 bar.
Dismount the non-return valve from the receiver.
