RENEWABLE  HEATING & COOLING TECHNOLOGY

MAINTENANCE

To protect the paintwork, avoid leaning or putting objects on the shell. External Heat 
Pump parts can be wiped with a damp cloth and domestic cleaner. (Warning: Never use 
cleaning agents containing sand, soda, acid or chloride as these can damage the 
surfaces.)

To prevent blockages in the titanium heat exchanger, ensure that the system 
incorporates a water and filter treatment facility. In the event of a problem occurring due 
to contamination, the system should be cleaned as described below. (Warning: the fins 
on the finned tube heat exchanger are sharp!).

Cleaning the Heat Exchanger and Pipework

Contamination in the pipes and heat exchanger can reduce the performance of the heat 
pumps’ titanium heat exchanger. If this is the case, the pipe system and heat exchanger 
must be cleaned by a technician.
Use only pressurized drinking water for cleaning.

Cleaning the air system

The finned heat exchanger, fan and condensate outflow should be clear of all 
obstructions (leaves, twigs, etc.) before each new heating season. These can be 
manually removed using compressed air or by flushing with clean water.
It may be necessary to remove the unit cover and air inlet grid first.

Attention: Before opening the unit, ensure that all electrical supplies are isolated.

To prevent the evaporator and the condensate tray from being damaged, do not use hard 
or sharp objects for cleaning.
Under extreme weather conditions (e.g. snow drifts), ice may form on the air intake and 
exhaust air outlet grids. If this happens, the ice must be removed in the vicinity of the air 
intake and exhaust air outlet grids to ensure that the minimum air flow rate is maintained.

Winter Shutdown.

To prevent frost damage to the unit when not in use the Heat Pump should be drained of 
all water. Failing this another form of frost protection should be considered and actioned.

Attention: The warranty does not cover damage caused by inadequate frost 
protection measures during the winter.

TROUBLE SHOOTING

This section provides useful information for diagnosing and correcting certain prolems 
which may occur. Before starting the troubleshooting procedure, carry out a thorough 
visual inspection of the unit and look for obvious defects such as loose connections or 
defective wiring.
