8.9 Refrigerant dryer maintenance
Safety precautions
The dryer circuit contains refrigerant. When handling refrigerant, all applicable Safety precautions
during maintenance or repair must be observed. Specifically be aware of following points:
•
Contact of liquid refrigerant with the skin can cause freezing. Wear special gloves. If contacted with
the skin, the skin should be rinsed with water. On no account may clothing be removed.
• Fluid refrigerant can also cause freezing of the eyes. Wear safety glasses.
• Avoid inhalation of refrigerant vapors. Check that the working area is adequately ventilated.
Be aware that internal components of the dryer such as the pipes can reach a temperature of up to 110˚C
(230˚F). Therefore, wait until the dryer has cooled down before removing the side panels.
Before starting any maintenance or repair work, switch off the voltage and close the air outlet valve.
Local legislation
Local legislation may stipulate that:
• Work on the refrigerant circuit of the cooling dryer or on any equipment which influences its function
must be undertaken by an authorized control body.
• The installation should be checked once a year by an authorized control body.
General
The following remarks should be kept in mind:
• Keep the dryer clean.
• Brush or blow off the finned surface of condenser regularly.
• Inspect and clean the electronic condensate drain regularly.
a. Functioning of the drain can be checked by pushing the TEST button of the drain, consult
section Air dryer.
b. Cleaning of the drain filter can be done by opening the manual drain valve during a few
seconds.
Device settings
The regulating and safety devices are factory adjusted to obtain optimum performance of the dryer. Do not
alter the setting of any of the devices.
Connecting pressure measuring devices in the refrigerant circuit can change the amount
of refrigerant in the system. This results in a less optimal working of the dryer.
8.10 Desiccant dryer maintenance
General recommendations and precautions
The desiccant dryer does not need extensive maintenance. Nevertheless, before carrying out any
maintenance or corrective activity, read the following recommendations and safety precautions and act
accordingly:
