3. Turn on the filter pump to supply water to the heat pump. Open the filter air bleeder and circu-
late water through the system long enough to bleed all the air out of the pool system. Check for
leaks in and around the heat pump.
4. Turn on the electrical power to the heat pump at the main breaker panel.
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 con-
taining 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.
