3.5 Swimming Pool Heat Pumps Electrical Wiring
NOTE: Although the unit heat exchanger is electrically isolated from the rest
of the unit, it simply prevents the ow of electricity to or from the pool wa-
ter. Grounding the unit is still required to protect you against short circuits
inside the unit. Bonding is also required.
The unit has a separate molded-in junction box with a standard electrical
conduit nipple already in place. Just remove the screws and the front panel,
feed your supply lines in through the conduit nipple and wire-nut the electric
supply wires to the three connections already in the junction box (four con-
nections if three phase). To complete electrical hookup, connect Heat Pump
by electrical conduit, UF cable or other suitable means as specied (as per-
mitted by local electrical authorities) to a dedicated AC power supply branch
circuit equipped with the proper circuit breaker, disconnect or time delay
fuse protection.
Disconnect - A disconnect means (circuit breaker , fused or un-fused switch)
should be located within sight of and readily accessible from the unit, This
is common practice on commercial and residential air conditioners and heat
pumps. It prevents remotely-energizing unattended equipment and permits
turning o power at the unit while the unit is being serviced.
3.6 Initial startup of the Unit
NOTE- In order for the unit to heat the pool or spa, the lter pump must be
running to circulate water through the heat exchanger.
Start up Procedure - After installation is completed, you should follow these
steps:
1
Turn on your lter pump. Check for water leaks and verify ow to and
from the pool.
2
Turn on the electrical power supply to the unit, then press the key ON/
OFF of wire controller, It should start in several seconds.
3
After running a few minutes make sure the air leaving the top(side) of
the unit is cooler(Between 5-10°C )
4
With the unit operating turn the lter pump o. The unit should also
turn o automatically,
5
Allow the unit and pool pump to run 24 hours per day until desired pool
water temperature is reached. When the water-in temperature reaches
this setting, the unit will slow down for a period of time, if the tempera-
ture is maintained for 45 minutes the unit will turn o. The unit will
now automatically restart (as long as your pool pump is running)when
the pool temperature drops more than 0.2 below set temperature.
