Suitable for models:

FO061HS
NOTES:
(1) Above wiring circuit diagram is for reference only, due to consideration of universal use, there might be some
difference from the actual circuit diagram, please refer to the one stuck on your heat pump.
(2) Ground wire of the swimming pool heat pump must be connected well, although the heat pump’s heat
exchanger has been already electrically isolated from the rest of the unit. Grounding the unit is still required to
prevent users from electric shock or unit damage by short circuits. Bonding is also required.
Disconnect:
A disconnect (circuit breaker, fused or un-fused switch) should be installed at the position readily
accessible from the heat pump unit. This is common practice for both commercial and residential heat pumps.
It prevents the unattended equipment from remotely-energizing and permits to turn off the power supply
when the unit is being serviced or at maintenance.
