Interval

Maintenance work

monthly

Inspection the drain tap for leaks by visual inspection from the outside

Inspection of the external hoses for material fatigue and leaks

Inspection of the hose clips for correct and secure fit

Inspection of the low level safety function (only for devices with heater)

Cleaning of the condenser (only for air-cooled devices)

Cleaning of the water filter (only for water-cooled devices)

quarterly

Decalcifying of the cooling water circuit (only for water-cooled devices)

A shorter interval must be selected, depending on water hardness and operating time

half-yearly

Inspection of the heat transfer liquid

7.3 Cleaning device

Personnel:

Operating personnel

WARNING!

Ingress of cleaning agents in the device

Electric shock



Use a moist cloth for cleaning.

Also note the following:

Only clean the control panel with water and detergent. Do not

use acetone or solvents. The consequence would be perma-

nent damage of the plastic surfaces.

7.4 Check low level protection

If the liquid level in the device drops so far that the heater is no

longer completely covered with liquid, an alarm sounds. The dis-

play shows

low level

. The components of the device, the cooling

unit, the heater and the pump are switched off by the electronics.

There must be an alarm signal as soon as low level is

reached.
