ELECTRICAL CONNECTION & CIRCUIT DIAGRAM

IMPORTANT. It is recommended that all electrical supplies and connections are carried out by a qualified electrician, in accordance with I.E.E. standards, latest issue, or local codes of practice as applicable.

Also recommended is a protected supply to incorporate fuses or motor type circuit breaker (Type C) to specified rating (see Data Sheet page 19).

An earth leakage trip (R.C.D) of the current operating type (30mA) is recommended to be fitted to all pool electric's.

N.B. This voltage must be available at the heat pump whilst running.

A 40 AMP / 2 Pole Contactor is required to interlock heat pump and circulation pump i.e. heat pump only functions when pool circulation pump is running. A flow switch (provided & optional - see page 5) can also be installed as an extra precaution in the event that there is a loss of water flow (i.e. circulation pump deprimes).

NOTE - PLEASE CHECK CONTINUITY OF FLOW SWITCH BEFORE INSTALLING.
