   TOP unit heaters

Unit heaters (2-stage three-phase motor/1-stage AC single-phase motor/continuously variable EC single-phase motor)

Installation and operating instructions

11  Decommissioning (longer term)

  Switch of 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 anti-

freeze!

12  Maintenance and cleaning

12.1 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.

12.2 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's 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).

 

 

Any oily deposits on steel heat exchangers can also be cleaned 

with ease using a steam cleaner.

12.3 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.

  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!
