Caution Risk of severe burns. As the cooling system
could become extremely hot during operation, make
sure the system is cool before touching.
Cooling system When cleaning the exterior of the cooling
system, for instance using water, disconnect all power sup-
plies. Be aware of the electric motor protection standard.
Cooler matrix The air fins of the cooler matrix can be cleaned
by blowing through with compressed air. If necessary, a high-
pressure washing system and degreasing agent can be used.
When using a high-pressure washing system point the jet
parallel to the air fins. See Figure 7.
Fan housing Remove the cooler matrix when cleaning the
inside of the fan housing. To clean the inside of the fan hous-
ing, use compressed air. If necessary a degreasing agent can
be used. Blow with compressed air from the electric motor
side through the fan guard.
Pump ORELL Tec will not be held responsible for any
interferen-ce in the pump such as internal cleaning. If the
pump has been run with contaminated oil, clean it by
running it with clean oil.
