1) Safety Precautions
2) Siting The Compressor
What you must do:
• Read these instructions before using
your air compressor.
• Ensure the compressor has been
installed, electrically connected and
piped in by a properly qualified person.
• Ensure the compressor is kept upright
at all times.
What you must not do:
• Do not attempt any maintenance on
the compressor until it has been isolated
from the power supply.
• Do not attempt any work on the
compressor until the air receiver and
pipe work systems are depressurised.
• Compressed air is dangerous if misused
and can prove fatal. Avoid any bodily
contact with compressed air.
• During operation the motor will
become quite hot to the touch. Avoid
contact to prevent burns. • Never
tamper with the pressure relief valve.
• Never lubricate the oil free motor or
pump assembly; this will cause severe
damage.
• Never obstruct cooling fans or outlet
vents.
What you must do:
• Provide adequate protection from the
weather.
• Site the compressor level in both
planes.
• Allow access for maintenance all
around the compressor.
• Site in a dry area, avoiding damp or
humid conditions. The site must be dust
free, well ventilated and have a cool
ambient temperature. 0 to 40°C should
be regarded as the minimum and
maximum allowable ambient.
• Ensure there is a minimum of 30cm
clearance around the compressor
What you must not do:
• Enclose the compressor or allow hot air
generated by the motor to recirculate
around the compressor.
• Restrict air flow around the end cover
ventilation grilles otherwise serious
damage may occur.
Electrical Connections
Where applicable, compressors are supplied with a moulded plug in accordance with
national standards.
Never remove the moulded plug.
The use of extension cables is not recommended as this may cause voltage drops
which can result in damage to the motor.
220v/50Hz models wired in accordance
with European Standard -
Blue = Neutral
Brown = Live
Yellow/Green Stripe = Earth

Wheel Kit [PT90]
Wheel Kit [PT90]
Your compressor comes complete with a
wheel kit. Firstly, fit both casters using
the supplied fixings with a 14mm
spanner. Lock both caster wheels in
place with the foot pedal before lifting
the compressor to fit the wheels. Place a
washer on the axle then fit the wheel,
holding it in place with the split pin.
Operation
Starting & Stopping
Plug the compressor into an outlet socket of nominal voltage.
All models:
As air is used the pressure drops and the motor will restart at the pre-set pressure.
There is approximately a 2 Bar differential.
PT90 –Turn the compressor on and off by turning the switch (I/O) on the top of the
pressure switch.
PTS20 - Press the green on off (I/O) switch on the front panel of the machine.
The PTS20 is fitted with a 4 amp overload protection. The reset button for the
overload protection is located above the on off switch on the front of the compressor
Note!
Each time the compressor switches off, you will hear a short hiss of air. You are
hearing the unloader valve discharging the residual delivery pipe pressure. This is
normal.
NEVER unplug the compressor when running. Always switch off using the red control
on the pressure switch to ensure the compressor discharges.
Failure to do so will cause damage and will invalidate your warranty.

Filter/Regulator [PT90]
Pressure Relief Valve
Adjusting Outlet Pressure
Use the pressure regulator to adjust the outlet pressure.
To increase line pressure, rotate the knob in a clockwise
direction; to decrease turn anti clockwise. It is possible to
lock the setting by pushing the knob down until it “clicks”.
There are two pressure gauges on each model.
The larger gauge indicates the air receiver pressure, the smaller gauge indicates the
air outlet pressure.
Routine Maintenance
Refer to preventative maintenance section for frequency. [Page 5]
Draining the Air Receiver
Drain water condensate from air receiver at a pressure of no more than 2 Bar. Slowly
open the drain tap provided to allow water to flow out. Fully close drain tap when all
water condensate has drained off.
Draining the Filter/Regulator Unit (PT90)
Drain water condensate from the filter regulator at a pressure of no more than 2 Bar.
Push the drain pin at the bottom of the filter regulator to allow water to flow out.
Note !
Water Condensate must be handled in accordance with national environmental rules
Check Pressure Relief Valve
Ensure the air receiver is not pressurised.
Unscrew the knurled end of the pressure relief valve until an
audible click is heard. Retighten without using excessive force.

We recommend the compressor has a maximum 65% duty cycle to prolong pump life
Note !
The motor must never be allowed to run continuously, otherwise it will overheat and
may become damaged. The duty cycle is calculated over 10 minutes, meaning that if
the motor runs for 6.5 minutes it must rest for 3.5 minutes before its next use.
Do not ignore air leaks. All air connections must be leak free to prevent the
compressor from overheating.
The compressor is fitted with a thermal overload. In the event of excessive
temperature, the motor will switch off. After about 50 minutes when the motor has
cooled it will automatically reset.
You must find the cause of the overload and rectify it before continuing to use the
compressor. Damage by continuing to use the unit is not covered under warranty.
