INITIAL OPERATION

Once the solar heater has been assembled and the hoses are connected to the filter pump and pool return, unblock the flow of water

into the pool return hose and turn on the pump and filter system. Bubbles will shoot out of the return nozzle into the pool initially

while air is pushed out of the solar heater. If this persists for longer than 2 or 3 minutes, check for and repair any leaks in the hoses

or connections.

FOR BEST RESULTS: To reduce heat loss, use a pool cover on your pool overnight, run your filter system during daylight hours

and cover the solar heater at night (if running the system).

MAINTENANCE

The solar heater should not require servicing or maintenance other than winterizing. Prior to the first frost, or at the end of your swim

season, the solar heater should be removed from its connections to the pool and stored in a frost free location.

Winterizing

Drain all the water from the solar heater by disconnecting the tubes. Store in a location protected from frost. Reconnect the pool return

tubes with a 1½"-1½" coupler (not included) or any properly sized 2-way valve if continued pool use is desired.

CAUTION: DO NOT ALLOW STANDING WATER INSIDE THE SOLAR HEATER TO FREEZE. WATER EXPANDS AS IT FREEZES AND

CAN RUPTURE THE SOLAR COILS ON THE HEATER.

TROUBLESHOOTING

Leaking heater

High filter pressure

SAVE THESE INSTRUCTIONS

Possibilities/Solutions

• Check to make sure that water is flowing through the holes. Check the flow strength at the

pool inlet.

• Has it been sunny?

• Put your pool cover on at night to prevent heat loss.

• Additional heaters may be necessary.

• If using a bypass kit, check and adjust flow restrictions if necessary.

• Check the setting of the filter to make sure it is returning water to the pool through the

pool water inlet.

• Check flow rate.

• Check the connections for a suction leak.

• Check to make sure the flow rate is normal.

• There could be a break in the tubing.

• There could be a clog in the tubing, try to purge out

the clog.

• Check the connector seals and replace or repair if defective.

• Flow through heather may be too high. A bypass kit may be needed.

• Filter may need backwashing or filter media change.

• Pool/spa system valves may need adjusting.

• Water return outlet may be blocked.
