3.5 Swimming pool heat pump electrical wiring
NOTE : Although the unit heat exchanger is electrically isolated from the rest of the unit, it simply prevents the

the unit. Bonding is also required.
The unit has a separate molded-in junction box a standard electrical conduit nipple already
in place. Just remove the on the front panel, feed your supply lines in through the conduit
nipple and the electric supply to the three connections already in the junction box
(four connections if three phase). To complete electrical hook up, connect heat pump by elec-
trical conduit, UF cable or other suitable means as (as permitted by local electrical au-
thorities) to a dedicated AC supply branch circuit equipped the proper circuit breaker,
disconnect, or time delay fuse protection.
Disconnect
A disconnect means (circuit breaker, fused or un-fused should be located sight of
and readily accessible from the unit, This is common practice on commercial and residential air
