C. PLUMBING & WATER CONNECTIONS
6. POOL/SPA COMBINATIONS W/SPILL-OVER
Use this diagram for a connected pool and spa, where the spa has a spill-over type waterfall into
the pool. Where
one pump and
one heater are
used for both
t h e p o o l a n d
spa. If the water
pump exceeds
1.5 H.P. then in-
stall a external
bypass as shown
on page 5.
SEE CHLORINATOR LOOP & CHECK
VALVE REQUIREMENT ON PAGE 5.

7. PLUMBING WITH SOLAR.

Plumbing for a system where a solar pool
heater is installed. It is strongly advised
that an automatic solar
control device be used
when used with the
heat pump. If the water
pump exceeds 1.5 H.P.
then install either of
the optional bypasses
as shown on page 5.
The heat pump and
solar can be operated
together. The heat
pump will share the heating load with the solar.
If the solar is operated on cloudy days, while rain-
ing, at night or at low air temperatures, it may cool
the pool or spa. An automatic solar control will shut
the solar off when there is no solar heat gain, otherwise
it should be shut off manually during these times.
To use the heat pump as a backup to the solar, set the heat pump thermostat 2 to 4 degrees below
the solar's target temperature setting. Therefore, if the solar is not maintaining water temperature,
the heat pump will come on to assist the solar. Some thermostat fine tuning may be required by the
user.
