7 Maintenance and disposal
7.1 Maintenance
The inverter is virtually maintenance-free. Nevertheless, we recom-
mend that you inspect it regularly to ensure that the fins on the
front and rear of the device are free of dust. Clean the device when
necessary as described below.
NOTICE!
Danger of destroying components on devices of
type coolcept 3 :
– Do not allow cleaning agents and devices to
penetrate between the fins at the front of
the inverter (under the grey hood).
– The following cleaning agents, in particular,
must not be used:
–
Cleaning agents that contain solvent
– Disinfectants
– Gritty or sharp-edged cleaning mate-
rials
Dust should be removed using compressed air (max. 2 bar).
DANGER!
Risk of death by electrocution! Use cleaning
agents only with a slightly damp cloth.
1. Remove heavy soiling with a slightly damp cloth (use clear
water). If necessary, use a 2 % hard soap solution instead of
water.
2. After cleaning, remove any soap residue using a slightly damp
cloth.
