refractometer can be bought from your heat pump supplier or online.

We need to test the operation of the unit against the hot water cylinder. So first we
need to draw off 50 liters of water, run a couple of taps for 5 mins to achieve this. The
unit should start up automatically in hot water mode, if it doesn't press the DHW
power button on the controller, in 3-4 mins it will start heating the cylinder, a coke
can symbol will show in the status section of the remote controller.
The heat pump should be able to achieve 48C cylinder temperature without using the
immersion heater.
While running, check the outdoor unit for damage & debris, the coil needs washing,
we recommend you use an approved EHS heat pump cleaning chemical, your
distributor will stock this. Instructions are given on the bottle. You also need to clean
and polish the outside casing we recommend car wax to do this.
