15. MAINTENANCE

Repair work beyond normal maintenance can be performed only by qualified personnel or
the manufacturer's representative.
Use only spareparts and accessories approved by the manufacturer.
Prior to any maintenance or repair work, switch off the compressor and disconnect it from
the mains (pull out the mains plug).
To ensure that the compressor works correctly, perform the following maintenance tasks at regular intervals
(Chapter 14).:
Prior to the following checks it is necessary to open the equipment housing (Fig. 4 )
15.1. Condensation drain valve
Compressors (Fig.11)
During regular use, release condensation from the pressure tank weekly.
At times of high humidity drain condensation daily.
• Switch off the compressor at the mains. Reduce air pressure in the
appliance to max. 1 bar by releasing air via a connected device.
• Place the hose with the drain valve into a container prepared in advance
and open the drain valve (1).
• Wait until condensation is fully drained from the pressure tank.
• Close drain valve (1).
Compressors with condensation and filtration unit (Fig.14)
During regular use, condensation is automatically released via the release valve of the condensation unit
filter. To check that the automatic drain is working properly, open the valve (4) of the drain vessel (2) by
turning to the left. Release a small amount of condensate from the vessel. Close the valve (4) by turning to
the right.
Compressors with air dryer
In the case of a regular operation condensate is automatically excreted via air dryer and it is entrapped in a
bottle located at the housing side. Take out the bottle from a holder, release blowing-out suppressor and
pour out the condensate.
If necessary, it is possible to connect the set for condensate discharge onto the condensate outlet (see
Chapter. Auxiliary Equipment).
15.2. Safety valve check
(Fig.10)
When the compressor is operated for the first time, make sure that the safety valve is working properly. Turn
screw (4) of safety valve (1) several rotations to the left until the safety valve releases air.
valve blow out for only a few seconds. Turn screw (4) to the right until it seats, closing the valve.
The safety valve must never be used for depressurizing the air tank. It could damage the
safety valve. The valve is set to the maximum permitted pressure by the manufacturer.
Adjustments are not permitted.
Warning! Compressed air can be dangerous. Wear eye protection when blowing air out.
15.3. Replacement of input filter
(Fig.12)
It is necessary to replace the input filter (1) or
(3) located in the lid of crank box of a
compressor every two years.
• Pull out the rubber plug (2) using a hand.
• Take out the used and contaminated filter.
• Insert new filter and put on a rubber plug.
