FLOW SWITCH INSTALLATION GUIDE (optional)

1.Insert reducing bushes (provided) into 1.5” Tee using suitable adhesive.

2.Connect 1.5” Tee to socket union adjacent to Inlet on heat pump. Tee can be installed horizontally or vertically!

3.Using PTFE tape insert flow switch into Tee making sure that the arrow on the flow switch points towards the heater.

4.Turn off electrical supply to heat pump. Run the wire lead from the flow switch and make connection to No. 1 & 2 on the electric terminal block - see diagram below (wire extension may be required). Note:- you will have to remove a pre-fitted loop that is already connected to No.1 & 2 see dia. below.

ANTI VIBRATION PADS AND DRAIN TUBE

The following parts should be installed prior to connecting pipework. Drain tube will not fit if vibration pads are not installed on the 12kW model!

X 4 ANTI VIBRATION PADS (PLASTIC)

Install on underside of heater. It is recommended that Stainless Steel screws & plugs are used when securing to floor. Installing anti vibration feet will also help prevent corrsion to the base of the heat pump.

1 X DRAIN VALVE (RUBBER) 1 X 2m FLEXIBLE DRAINAGE TUBE

Insert drain valve into drainage hole located on underside of heater and push fit the drainage tube onto valve (Tip-you will find it much easier to insert drain valve if it is immersed in hot water or sprayed with silicone spray prior to fitting). Drain valve installation is optional.
