11 Maintenance
11.1 Essential Checks
Periodically clean the in-line filter (Y strainer or Spirotrap); this will need to be every
month for the first 6 months following start up of the system to allow installation
debris to be extracted. NOTE that a lack of water in the system or debris/dirt
entering the system can damage the unit.
11.2 Advisory Checks
Although there is no formal requirement for annual maintenance of the unit, the
following checks are strongly suggested:
Check the grill and evaporator for debris and remove before cleaning the evaporator.
Check the water supply and air vents frequently, to ensure that there is adequate
water within the system and that air is kept out of the system.
Check each part of the unit and the pressure within the system.
If any component has failed, replace it (and recharge refrigerant, if any has been
lost).
Check over the power supply and the electrical system generally to make sure that
no wires are lose or degrading. You must investigate any scorching visible or unusual
smells coming from the unit or the wiring.
Replace any part that may be malfunctioning; it is better to replace a part early (to
practice good preventative maintenance) than await failure.
If the heat pump is not to be used for a long period of time, please drain it down and
seal the unit to keep it safe for recharging and restarting when needed.
If a period of non use will include any possibility of the unit freezing, isolate the unit
and drain the water from the lowest point of the heat exchanger. Recharge the
water/glycol and carry out a full inspection of the unit before it is restarted.

The water loop of the heat pump MUST be protected from freezing in winter.
Please NOTE THE FOLLOWING – failure to observe the following requirements
WILL invalid the warranty for the heat pump.
