How to service the cross-flow heat exchanger
Interval
The cross-flow heat exchanger is serviced once annually.
Before start
The following should be available before start:
•
A soft brush
•
Fat-dissolving detergent
•
High-pressure cleaner with atomizer
Warning!
Do not forget to disconnect all current to the unit and its parts before service.
Take care when cleaning the exchanger so that you do not damage the surface of the
heat exchanger.
Avoid the use of hard objects on the surface.
Special
conditions
Where a unit is used in connection with exhaust e.g. from a kitchen with fatty air,
exhaust hood filters etc. must be cleaned every day to ensure optimum performance
and to protect the heat exchanger. The unit must be switched off, when the fat filters
are removed.
