12 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!
Important! If there is a risk of frost (it is essential that you take these meas-
ures if the unit is not protected from freezing up in another way):
•
Shut off the heat exchanger.
•
Drain water out of the heat exchanger!
13. Maintenance
13.1 Housing
The ProtecTor housing is maintenance-free. Dirt on the housing does not
affect the operation of the unit. Cleaning is only necessary for aesthetic
reasons.
13.2 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 heat exchanger
of the ProtecTor for dirt and clean if necessary. Check the unit 2 x a year,
and more often in less favourable conditions (high dust content in the air).
Carefully blast the heat exchanger with compressed air to remove accumu-
lated dust (aluminium fins).
Heat exchanger in use contains (residual) water! Protect from frost!
13.3 Motor
Immediately rectify any defects established on systems / assemblies / equip-
ment. If the defect constitutes an acute danger, then do not operate the
unit / system in its defective state.
• Pay attention to all safety and operating guidelines (EN 50 110, IEC 364)
when performing set-up and maintenance work.
Disconnect the motor from the mains voltage supply and prevent it from
being re-connected!
