NOTE:
(1)The above electrical wiring diagrams are only for your reference, please subject the heat
pump to the posted wiring diagram.
(2)The swimming pool heat pump must be earthed well, although the unit heat exchanger is
electrically isolated from the rest of the unit .Earthing the unit is still required to protect you
against short circuits inside the unit .Bonding is also required.
Disconnect: A disconnect (circuit breaker, fused or un-fused switch) should be located within
sight of and easily accessible from the unit. This is common practice on commercial and
residential heat pumps. It prevents remotely-energizing unattended equipment and permits
turning off power to the unit while the unit is being serviced.
