Maintenance work between scheduled services
Weekly: Inspect / replace
supply air filter
(optional accessory)
Check
the function of the optional supply air filter mats:
– 1x monthly, but at least every 500 operating hours.
– If the air intake is very contaminated, this should be carried out at more
frequent intervals.
Change
the supply air filter mats:
– If a dirt crust has become deposited on the filter mats.
– If the final compression temperature rises to
7.2
° to
9
°F above the target
value (the dirt crust on the filter mat prevents the provision of an adequate
cooling air supply).
Changing the supply air filter mats
1. Switch off the compressor with the OFF button.

NOTICE!
Keep a packet of spare filter mats in reserve at all times!
WARNING: Risk of injury!
Press the emergency stop button, use the mains disconnection device to iso-
late the compressor from the power supply and fix a padlock to prevent the
power from being switched on again unintentionally.
WARNING: Risk of injury!
Caution: Beware of the danger of sustaining cuts from sharp sheet metal
parts on the filter mat.
It is essential that you wear protective gloves!
2. Draw the filter mat (1) upwards out of
its holder.
3. Insert a new mat in the holder.
