5. Maintenance
All maintenance work should be carried out after
cooling of the machine.
Close the inlet and outlet valves and release the
pressure in the dryer by operating the test key on the
condensate drain. Then switch off the power voltage.
Open the circuit breaker to prevent unintentional
starting.
Only perform maintenance work and repairs with
suitable tools and safety wear. Only use original
spare parts. Do not perform repairs in the refrigera-
tion dryer yourself, contact the dealer.
Observe cleanliness during all maintenance work.
Cover components and exposed openings with clean
cloths, paper or tape to keep dirt away. Under no cir-
cumstances should corrosive or inflammable sol-
vents or carbon tetrachloride be used for the
cleaning of components. Protect the motor and
electrical components against moisture, for exam-
ple, during steam cleaning.
Under no circumstances should welding or other
modifications be carried out on the pressure vessel.
If overheating of an internal component is
suspected, stop the machine. Do not open any
panels until the machine has cooled down sufficient-
ly to avoid the risk of spontaneous inflammation of
the oil vapours at the air inlet.
Under no circumstances use a light source with open
flame to inspect the interior of the device.
Ensure that no tools or other loose parts are left in or
on the machine.
Prior to releasing the refrigeration dryer for renewed
operation, ensure that the settings for operating
pressure, temperature and time are correct. Check
whether the control and cut-off devices are installed
and in perfect working condition.
6. Cleaning
Always keep the refrigeration dryer clean.
Take the same safety precaution before cleaning as
those before maintenance.
Clean the filter once a week. To this purpose, remo-
ve the filter from the automatic condensate drain.
Clean from the inside to the outside with an air jet.
Then re-install the filter.
Brush or air-blast the ribbed surface of the conden-
ser once per month. Do not clean with water or
solvents.
7. Storage
Store the device in its original packaging vibration-
free in a dust-free and dry place at a temperature
between 0 °C and 40 °C.
