• check the connection terminals for tight fixation when the unit is installed and once again after an operation
time of 30 days.
CAUTiOn
The power contactors of the compressors must be checked on smooth operation and worn
contacts every 10 years.
Unit interior
Clean pipes simplify the search for leaks.
Vibrations of pipes and circuit components can result in leaks.
• check the pipes for a tight seat.
Condensing air humidity on cold water pipes means a loss of cooling capacity.
• check the insulation of the water piping.
dAngER
Mortal danger by electric hazard
When the master switch is switched on and the controller is stopped, the power contactors are
live, even if the components are not operating.
At the fan contactor, dangerous voltages occur. Do not open the unit within the first 5 minutes
after disconnection of all phases.
Due to the EC fans dangerous charges of >50µC can occur
for a short time between AC line terminals and PE after disconnection.
