Plumbing & Water Connections with Solar

Plumbing for a system where a

solar pool heater is installed. It is

strongly advised that an auto-

matic solar control device be

used when used with the heat

pump.

The heat pump and solar can be

operated together. The heat

pump will share the heating load

with the solar. If there is no heat

coming from the solar panels, the

solar control device will turn off

the solar by rotating the motor

valve, otherwise it should be

turned off manually. The heat

pump will then maintain the

pool/spa temperature.

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 set-

ting. 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.

Plumbing & Water Connections for Above or Below Water Level

If you install the heat pump above or below the pool or spa water level by more than 3 feet, the internal

water pressure switch may be effected by the static pressure of the pool water. In some cases it may

be necessary to install a water FLOW switch. The water flow switch is not effected by changes in

water pressure but only water movement. We suggest installing the Grid Brand Model 20 or 25, external

flow switch and disabling the internal water pressure switch. Plumb in the flow switch as shown here.

Then run a THREE wire insulated cable from the flow switch into the heater and attach to the existing

water pressure switch leads located behind the large service panel and wire as shown below.

FORE CONTINUING. REVIEW UNIT WIRING DIAGRAM ON PAGE 10 & 11 ALSO !

If the water pump exceeds 1.5 H.P. then

install either of the optional bypasses as

shown on page 5.

NOTE: If the solar is operated on cloudy days, while

raining, at night or at low air temperatures, it may cool

the pool or spa. A automatic solar control will shut the

solar off when there is no solar activity, otherwise it

should be shut off manually during these times.
