sion, clean if necessary with compressed air or steam jet. Check the function and correct rotation.
Spray the wheels with silicone spray if necessary.

9.10.1 Plate heat exchangers
Plate heat exchangers are made of highly corrosion-resistant high-grade aluminum and have no
drive or moving parts. The lifetime is nearly unlimited, as long as the differential pressure between
the plates does not exceed the maximum allowed and operating instructions are followed.
The only maintenance required is cleaning:
-
Clean the condensate drain, inspect and fill the U-trap. The plate pack is normally self-clean-
ing.
o
Remove fibers and dust at the exchanger inlet with a brush.
o
Clean oils and fats with hot water, household cleaners or degreasing steam.
-
Check for proper operation of the differential pressure switch
–
for function refer to

If there is a bypass damper, please refer to
chapter 9.7 (Dampers)
.
NOTICE!
Attention!
Heat exchanger must not be damaged mechanically or chemically through clean-
ing.
