13. 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).

For permanently high efficiency of drying, it is necessary to maintain the whole appliance,
and mainly ventilator clean – regularly clean the surface of ventilator and cooling fins of
cooler.

TO ENSURE THAT THE COMPRESSOR WORKS CORRECTLY, PERFORM THE FOLLOWING
MAINTENANCE TASKS AT REGULAR INTERVALS (CHAPTER 12).:

13.1.

Condensation drain valve

Compressors

(Fig.14, Fig.15)

During regular use, release condensation from the pressure tank.
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 (for
compressors DK50 2V/110 and DK50 2x2V/110 orientate the vessel
towards the

drain valve,

for compressors

DK50 2V place the vessel

under release valve) 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.18)

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 Chap. PARTS LIST - Auxiliary Equipment).
