Maintenance
The heat pump should be serviced ONCE A YEAR to comply with the warranty.
The installer should provide you with evidence of all servicing so that you can keep a log in the event of any warranty claim.
Maintenance should be covered by the installation contractor. If the installer is not available, another Ecogenica-qualified contractor can take over the maintenance and warranty.
The annual service should include the following:
- Stop the unit, clean the Magnetic Filter and replace the strainer.
- If Glycol or an anti-freeze is in the system, test the level using a Glycol tester - the level should be 25%. If you don’t have a glycol tester, a glycol tester/refractometer can be bought from your heat pump supplier or online.
- Refill the unit, pressure should be 0-3 bar, then open all valves.
- The operation of the unit against the hot water cylinder needs to be tested. First, draw off 50 litres of water - run a couple of taps for 5 mins to achieve this. The unit should start up automatically in hot water mode, but if it does not, press the DHW power button on the controller. In 3-4 mins it will start heating the cylinder, and a compressor symbol will show at the top of the remote controller. The heat pump should be able to achieve 50C cylinder temperature without using the immersion heater.
- While running, check the outdoor unit for damage and debris.
- Clean the coil. We recommend using an approved air conditioning or heat pump cleaning chemical - your distributor will stock this. Instructions are given on the bottle.
- Clean and polish the outside casing - we recommend car wax or ACF50 to do this.
- Measure the temperature of the flow using the remote controller (See Section 10).
- Measure the flow rate from the flow meter (See Section 10).
- With the unit running flat out, measure the air temperature as it enters the coil and the air in the garden. They should both be the same. Check that cold air is not recirculating.
