Printed in the USA
• Install product on a rigid level surface maintaining a minimum of 6 in/15
cm clearance all around the unit and a 12 in/30 cm clearance above the
system.
• Sufficient cooling from the surroundings is important. Place the system
in a dustfree, dry and cool, yet frostfree, room. Do not install in a closed
cupboard, unless adequate openings for ventilation are available on top
and bottom (minimum 500 cm²/77.5 in² each). If the system is placed
under a table, a minimum of 12 cm/5 in free height must be available
above the system or an opening of Ø30cm/11.8 inches, corresponding
to the top of the system, may be cut in the table. Ensure that the system
stands firmly on the floor.
• The intake air may be supplied from another place (for instance outside).
Ensure that hoses for the intake are sufficient to avoid performance loss
and that any alternate filter used has the same micron rating (50μm) as the
JUN-AIR intake filter.
Electrical installation
Warning!
Incorrect electrical connection may result in electric shock. The
electrical connection must be carried out in accordance with
local electrical regulations and by qualified electrical engineers.
Note!
Earthing of all AC models must be ensured during installation. The capacitor
must be earthed, as failure to do so may cause electric shock when touched.
Plug the system into an earthed socket of nominal voltage and ensure that
fusing is adequate.
AC models
• For electrical connection, refer to schematic in back of this manual.
• Check system serial number label for frequency and voltage to ensure
that it corresponds to the voltage and frequency used for the system. The
voltage stated on the system plate: 120/240V (/) means that the system
can operate at 120V or 240V, but this requires recoupling of the internal
wiring from the electrical system (see the electrical diagrams). 220-230V
(-) means that the system may operate within the range of 220V to 230V
without recoupling of the internal wiring.
• Capicitor is wired to motor via terminal box on side of motor.
• Accessorries are wired through the system pressure switch.
Operation
• If the temperature of the system is extremely low (for instance after
transportation or stocking), allow system to get to room temperature before
switching on the system.
• Do not use system for compression of liquids and dangerous gasses,
such as petrol vapour and solvents.
Important
This system is only suitable for atmospheric air.
• Do not remove protection covers during operation as it may cause electric
shock or risk of other personal injury (ie: terminal box, pressure switch).
• Ensure that system is correct for air supply flow required, see Technical
Specifications.
• Open the outlet cock on the receiver and connect equipment.
Adjustment of pressure switch
Warning!
If maximum pressure is exceeded, reduced lifetime may result.
Contact JUN-AIR for information on operation at higher
pressure.
• All systems may run at 100% continuous operation, but 50% operation is
recommendable to prolong lifetime.
• The system should be sized so that the tank is capable of supplying air
100% of the time and the compressors only run at 50%.
• Do not lubricate the oil-less system with oil, as this will destroy important
components.
• Start the system using the 0/1 switch on the pressure switch. The system
will automatically switch off at the preset pressure. If the system does not
start it may be due to pressure in the receiver, and the system will then
start automatically when the pressure reduces to approx. 6 bar/87 psi.
• Adjustment of pressure (see back of manual)
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).
Fault finding and repair
Important!
Switch off and isolate from electrical supply before removing
any parts from the system. Empty air receiver of air before
dismantling parts of system unit’s pressure system.
1. System does not start:
a) No power from mains. Check fuses and plug.
b) Breakage or loose joints in electrical connections.
c) Defective capacitor.
d) The thermal protection has switched off the pump due to overheating.
When cooled the pump will automatically turn on at a suitable
operation temperature. Go through the points in step 5.
e) The system has not been unloaded and there is back pressure. Make
sure that the system is unloaded each time it stops.
f) The pump is locked.
g) Pressure in the air receiver is too high for activation of the pressure
switch. The pressure switch makes circuit only when pressure has
dropped to preset start pressure. Empty receiver.
2. System does not start, makes a buzzing sound followed by a
clicking noise (cannot start against high pressure):
a) Leaky non-return valve. Remove the flexible pressure pipe and clean
to find out whether air leaks from the valve. If so, clean or replace.
3 System works, but pressure does not increase:
a) Intake filter clogged. Replace.
b) Leaks in fittings, tubes or pneumatic equipment. Check with soapy water
or by letting unit stay overnight with disconnected mains. Pressure drop is
not to exceed 1 bar.
c) Cups are worn out. Check and replace if neccessary.
d) Defective valve plate. Contact your JUN-AIR distributor.
e) Burr or failure in non-return valve which is creating a flow restriction.

Preventive maintenance
Weekly
Drain condensate from air receiver. If
equipped with autodrain, this will take
place automatically, however, drain
bottle has to be emptied.
If compressor is fitted with outlet filter,
check and empty for water by pressing
the black button at the bottom. If fitted
with autodrain, this will take place
automatically.
Check motor, air tubes, hoses and
equipment for leaks, and check the
pumping time.
Clean unit or wipe with a soft, damp
cloth. If necessary, use paraffin on rag
to remove sticky adhesions. Dust and
dirt prevent cooling.
Check intake filter. Clean or replace if
necessary. Minimum every 2000 hours
Replace silencer (intake filter), if
necessary
Check the O-ring in the non-return
valve and replace, if necessary.
Note! Empty receiver of air before
dismounting.
Check filter regulator, clean or replace
as neccessary
Test the safety valve by gently pulling
the ring with pressure in the receiver.
4. Loud noise from system:
a) Dirt or failure in non-return valve. Clean or replace.
5. System gets very hot:
a) Leaks. See above
b) Too high ambient temperature. Ensure adequate ventilation if the
vacuum pump is installed in a cabinet.
c) Overloaded. Ensure system is correct model for work load.
6. System starts when no air is being tapped:
a) Leaks. Step 3 - b
7. System does not switch on against pressure or does not switch
off at max. pressure:
a) Defective pressure switch. Replace.
Non-return valve Maintenance (NRV)
·Once a year.
·Switch off system on the main switch and pull out the plug.
·Pull the ring at the end of the safety valve (see back of manual).
Warning:
Loud noise!
·Let pressure fall to 0 bar. The pressure is to be read on the pressure
gauge for receiver pressure (see back of manual).
·If the system is mounted with a TÜV-approved safety valve, the receiver is
emptied by loosening the screw at the end of the safety valve
·Dismount non-return valve from receiver
·Disassemble non-return valve and remove O-ring from piston
·Clean non-return valve.
·Mount new O-rings and re-assemble non-return valve (Two O-rings in non-
return valve)
Monthly Annually 2000 Hours
Filters and non-return valves should be serviced every 2000 hours. The JUN-AIR basic service kit (identified in the accessories
portion of this manual) can be purchased to accommodate.
The comprehensive service kit includes components to maintain the system’s compressor (cups, valves, o-rings, cylinders) as well as
the systems filter elements, unloader valve, silencer, & NRV.
Comprehensive service kits should be utilized every 8000 hours.
Any solenoid accessories on the system should be serviced every 12000 hours.
Check the Pumping Time
The pumping time indicates the condition of the compressor provided that
there are no leaks in the system where the compressed air may leak. Test the
compressor as follows:
1. Empty the air receiver of compressed air ( the pressure gauge shows 0 Bar)
2. Close the outlet on the air receiver and check that the drain cock is closed.
3. Start the compressor and note how long it takes until it switches off.
Ensure that the pressure in the air receiver is 8bar/120 psi as deviations may
indicate the wrong results (see technical Specifications for pumping time)
Important!
Always test the compressor when cold as the time indicated
refers to the pumping time of a cold compressor. The pumping
time of a warm compressor is much longer and consequently,
the result would be misleading.
WARNING: To Avoid Serious Burns:
Do not touch surface during
operation.
Indicates package should be handled with
these symbols pointing up.
FRAGILE: Handle package with care.
Indicates this package must be kept dry.
