5) Routine Maintenance

Refer to preventative maintenance section for frequency.
5.1) Draining the Air Receiver
Drain condensate from air receiver at a pressure of no more than 2 Bar.
Automatic drains where fitted do not require draining, however the condensate tank
will require emptying – see following section "Operation Dryer Models".
Note !
Waste condensate must be handled in accordance with national environmental rules.
5.2) Check Pressure Relief Valve
Fig. 6 Pressure relief valve positions
6) Operation – Dryer Models
When equipped with an air dryer unit, the compressor will automatically dry the compressed
air before it is stored in the air receiver. This happens automatically and requires no additional
maintenance.This eliminates the need to manually drain the air receiver.
Fig. 7 Condensate tank locations
Do not exceed the recommended 50% duty cycle, otherwise the dryer will not activate
and the humidity of the air will increase.
Ensure the after cooler fins are kept clear of accumulated dust.
Slowly open the red coloured drain tap
provided to allow water to flow out – see fig 5.
Fig. 5 Drain tap types
Close drain tap when all water has drained off.
Draining is not required on dryer equipped
models.
Ensure the air receiver is not pressurised.
On "S" models, refer to section 8: Removing
Housing Cover
Unscrew the knurled end of the pressure
relief valve until an audible "click" is heard.
Retighten without using excessive force.
Operation is similar to standard versions with
the following change :-
Each time the compressor switches off or the
power supply is interrupted, the dryer purge
valve opens and automatically activates
the drain valve on the after cooler filter
allowing the dryer tower to regenerate. All
accumulated moisture will discharge into the
condensate tank.
This should be emptied when it reaches ¾ full.
