Heat exchanger, operation and
maintenance instructions
Inspection
1. Inspect the fins for fouling. Inspection can be
carried out through e.g. an inspection door to the
filter section.
2. Check the auto defrosting function and make sure
that the bypass damper closes securely when
defrosting is not in progress.
3. Check the drip tray, drainage and water trap
function. A water trap without a non-return value
should be filled with water.
Cleaning
If cleaning is required this can be done with a vac-
uum cleaner, blowing with compressed air or by using
detergent suitable for aluminium and rinsing off with
hot water.
Cleaning is best done by flushing water through every
single air duct (possibly adding ordinary detergent that
does not corrode aluminium) across the entire length
of the heat exchanger.
At operating temperatures below 0°C the heat
exchanger assembly must be dry before being
commissioned.
Damper, operation and maintenance
instructions
Inspection
1. Check the function of the damper actuator.
2. Check the dampers for tightness when they are
closed. If they are not sealed, adjust the damper
actuator to make the damper tight.
3. Check the sealing strips.
Cleaning
Clean the damper blades with a cloth. If they are severely
fouled, an environmentally friendly degreasing agent
can be used.
