General Information

Solar Heater features an innovative dome design that provides better heat transfer than traditional solar systems, and also eliminates the need to set aside yard space for conventional solar panels. With the hose connectors provided, Solar Heater fits filtration systems which require either 032mm (1 1/4in) / 38mm (1 1/2in) soft hose connection or 057mm (2 1/4in) threaded nut hose connection.

How It Works

Solar Heater should be installed between the pump / filter and return inlet of the pool.
Cold water flows from the pool water outlet to the pump/ filter and through the solar
heater. Water is heated while flowing through the heater coils, and then back to the return inlet of the pool.

Points to Note:

1. Installation
   Before installation, make sure you have filled your above-ground pool with water and it is connected with necessary filtration hoses which are connected with the filter and pump.
   The solar heater will become very heavy after filling with water. Select a proper site for the solar heater before installation. The solar heater should be installed, lower than the pool water lever, on a completely level, very firm ground or equivalent. The solar heater should face in a SOUTHERLY direction and its stand should be released for an optimal solar angle.
   WARNING: Turn off the pump before installation and disconnecting the solar heater from your filtration system.
   WARNING: Never place the solar heater close to any pool chemicals as chemical fumes and/or spills can cause severe corrosive attack.
   CAUTION : The solar heater must be positioned so as to prevent it being used as means of access to the pool by young children.
   CAUTION : Never stand or sit or put any object on the main base and dome cover.

2. Solar heater operating pressure
   Make sure that the solar heater operating pressure must not exceed 1.5bar {21 psi). It is recommended to have a pressure gage installed before the solar heater after the pump/filter to monitor the water pressure going inside the solar heater.

3. Linking additional solar heaters
   Never install additional solar heaters when filtration/pump is under operation. Always turn off the pump before heater installation or disconnection.

Solar Heater Installation

Before installing Solar Heater, check to make sure all parts are present in the package.
Primary Component

The only tool you need is a screwdriver with which to secure the hose clamp for hose connections to the hose connectors.

Pool layout with Solar Heater

Under the main base, there are two holes for hose connector assembly; one is located in the center and another one is on the side. Water flows in the heater coils from the center hose connector and  then out through the side hose connector back to the pool. Longer hose is provided for the connection of the heater to the pump/filter, and short hose is provided for connection of additional heater as shown. If the length of hoses provided does not fit your pools, you can use another soft hose with same diameter.

Hose Connectors on the Main Base
Two hose connectors are preinstalled on the bottom of the main base. Center hose connector is for hose connection to the pump/filter. Side hose connector is for hose connection to the pool return or additional solar Heater.
Before connecting to the hose, turn the side hose connector anticlockwise as shown until it stops. The openings of 2 hose connectors should point in opposite directions

To detach the hose connectors from the main base, turn the connectors clockwise until it stops and then pull it away. To assemble the hose connector to the main base, reverse the steps to finish the assembly.

Assembling Dome Cover to Main Base
NOTE: Start this assembly after finishing all hose connections.
There are 4 tabs on dome cover and 4 slots on the solar heater base. Push the tab into the slot to secure the dome cover on the heater base.

CAUTION: Don’t hold the dome cover to move the whole unit. Connecting the Solar Heater to the pool
CAUTION: Before beginning to connect this solar heater to your pool, make sure your pool water outlet and return inlet are closed and already connected with hoses. Refer to your pool manual or consult your pool dealer for proper instructions.
CAUTION: Turn off the pump before following installation
For pools using hose connection of Dia. 32mm (1 1/4in) 138mm (1 1/2in) Soft Hose

1.  Detach the pool return hose from your pump/filter.
2.  For soft hose of 032mm (1 1/4in), directly slide the hose to the hose connectors as far it can go. Use the hose clamp to secure the hose connection.
3.  For soft hose of 038mm (1 1/2in), use either long hose provided or another soft hose in same diameter to connect the pump/filter and middle hose connector. Firstly, insert the hose reducer inside of cuff of long hose and slide it onto the hose connector as far as it can go. Use hose clamp to secure the hose.

For pools using hose connection of Dia. 57mm (2 1/4in) soft hose with Threaded Nut

1.  Detach the pool return hose from your pump/filter.
2. Use soft hose of either 032mm (1 1/4in) or 038mm (1 1/2in) or to connect the center hose connector to the pump/filter. Make sure the hose is secured by the hose clamp.
3. Screw the threaded nut hose connector to the side hose connector. Make sure the 0 ring is inside the threaded nut hose connector.
4.  Screw the threaded nut of the hose, which is connected to the pool return inlet, to the threaded nut hose connector. Make sure the flat gasket is placed between threaded nut hose connector and hose threaded nut.

For multiple Solar Heaters

Depending on the weather conditions, 1 heater is recommended per 10,000 liters of pool volume.
NOTE: Make sure to have enough hose clamps and hose reducers before linking additional solar heaters. A hose reducer is required for 038mm(1 1/2’in) hose connection, and a hose clamp should be used to secure all hose connections. For one additional solar heater, use short hose provided and hose reducer to connect the additional solar heater.
For connection of 3 or more heaters, it requires a 3-way valve (not included) and “T’connector (not included) to be installed. Below is an example of above ground pool with 3-way valve set up in place. ATTENTION: Make sure to completely open the valve (3 holes) in operation.

Initial Operation

Before turning on your pump, make sure all hose connections are secured and hoses are not kinked or bent at severe angle before operation.
Make sure to unblock pool water outlet and inlet to let water flows into the hoses.
TIPS:
It is recommended to place a pool solar cover on at night to prevent heat loss.
On hot days, put the dome cloth cover on when your pool does not need additional heating.

Winterizing and maintenance

• WARNING: Turn off the pump before disconnecting the heater/hoses from your filtration system.
• For winterizing, block the pool water inlet and outlet and then disconnect the solar heater from the hoses.
• Drain all the water out of the solar heater at the end of the season. Water left inside may freeze, causing the material to rupture as the ice expands.
• Detach the hose connectors and close the two holes under the main base to prevent insects from making a winter home inside.
• To protect the solar coils, always put the dome cover on for storage.
• Retract the stands and store the solar heater in a place protected from frost.
• Don’t put any object on the solar heater and its dome cover.
• Always store the solar heater out of reach of children.
