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.
