• 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 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.
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.
