14. STORAGE
If the compressor will not be used for a prolonged time period, drain any condensate from the air tank. Then
turn on the compressor for 10 minutes, keeping the drain valve open (1) (Fig.14, Fig.15). Switch off the
compressor by switch (3) at pressure switch (2) (Fig.13), close the drain valve and disconnect the appliance
from the mains.
15. DISPOSING OF THE APPLIANCE
• Disconnect the appliance from the mains.
• Release air pressure in the pressure tank by opening the drain valve (1) (Fig.14, Fig.15).
• The components of the product are non-toxic.
• Dispose of the appliance following all environmental regulations.
16. REPAIR SERVICE
Guaranteed and post-guarantee repairs must be done by the manufacturer, its authorized representative, or
service personnel approved by the supplier.
The manufacturer reserves the right to make changes to the appliance without notice. Any changes made
will not affect the functional properties of the appliance.
17. SOLVING PROBLEMS
Caution! Before proceeding, depressurize the air tank to zero and disconnect the
appliance from the mains.
After the remedy of failure and reverse assembly of drier, it is necessary to perform the regeneration
of drier, best at continuous operation of compressor at pressure of 0.6-0.7 MPa for at least 1 hour
and then to check air drying.
Troubleshooting can be performed only by qualified personnel.
FAILURE POSSIBLE
CAUSE
REMEDY
No voltage in pressure switch
Check voltage in socket
Check fuse – replace faulty one
Loosen terminal – tighten it
Check power cord – replace faulty one

protection
Faulty capacitor
Seizure of piston or another rotary part Pressure
switch does not switch on
Replace motor or re-wind it
Replace capacitor
Replace damaged parts
Check the function of pressure switch
Compressor often switches
on

Devaluated or very polluted dessicant
Change the dessicant and filters
low operating pressure
reduce the air offtake, check the source efficiency,
check possible leaks in the distribution
inoperative solenoid valve
repair or change the valve
clogged nozzle of the regenerating air
clean or replace the nozzle, use correct size of the
nozzle (see Product maintenance)
inoperative cooler ventilator
replace ventilator check supply of electric energy
Dryer doesn´t dry (condensed
water in the tank)
leak of white liquid through the solenoid valve
dismantle the chamber, replace drying substance,
bottom filter and sealing and inspect tightness,
apply soapy water onto O-rings of the nuts
defective solenoid valve
replace the valve
damaged damping substance in the condensate
vessel
replace damping substance or the vessel
Drying unit is noisy or sounds
annoying
damaged pressure hose
replace pressure hose
