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.
Troubleshooting can be performed only by qualified personnel.
MALFUNCTIONS
Compressor does not
start
Compressor often
switches on
Low pressure in air
tank (compressor
running constantly)
Prolonged operation
of the compressor
Compressor is noisy
(knocking, metal
noises)
Dryer doesn't dry
(condensed water in
the air) *
)* After a dryer malfunction, the interior surfaces of the air tank must be thoroughly cleaned and all
condensed liquid removed.
Check the dew point of the air leaving the air tank (see Chapter 5 - Technical data) to protect the
equipment from damage!
