Installation and operating instructions
10. Decommissioning (longer term)
Switch off all electrical components.
If there is a risk of frost, it is essential that the heat exchanger and
pipework are protected from freezing by the use of antifreeze!
11. Maintenance and cleaning
11.1 Housing
The galvanised unit heater housing is maintenance-free.
Dirt on the housing does not affect the operation of the unit. Cleaning
is only necessary for aesthetic reasons.
11.2 Heat exchanger
Dusty and oily deposits on the fins of the heat exchanger restrict the air
flow and heat transfer. Only a clean heat exchanger will produce its full
heat output in the long term. For this reason, regularly check the unit
heater heat exchanger for dirt and clean if necessary.
Check the unit heater once a year before the start of the heating
season, and in less favourable conditions (high dust content in the air)
even monthly.
Carefully blast the Cu/Al heat exchanger with compressed air to remove
accumulated dust. Proceed extremely carefully, as the aluminium fins
bend very easily (bent fins have to be straightened with an appropriate
tool).
11.3 Motor
Immediately rectify any defects established on systems/assemblies/
equipment. If the defect constitutes an acute danger, then do not
operate the unit / system in its defective state.
Note safety and operating guidelines (EN 50 110, IEC 364) with all
repair and maintenance work.
Disconnect the motor from the mains voltage supply and prevent it from
being re-connected!
