SWIMMING POOL SOLAR HEATING SYSTEM
INSTALLATION MANUAL

SPECIAL SYSTEM LAYOUTS Use a divided system when installing more than the recommended maximum number of collectors per row, when avoiding roof obstructions, or where limited space dictates. This provides uniform distribution of water through all the collectors. If water distribution through the collectors is non-uniform, the heating capacity of the system will be reduced.

WHEN INSTALLING A DIVIDED SYSTEM, THE OUTLET HEADERS FROM EACH OF THE LOWER (OR CLOSEST) ROWS OF COLLECTORS MUST BE CONNECTED TO THE HIGHEST (OR FURTHEST) POINT IN THE SYSTEM. Refer to Figure 11. A divided system requires an Add-A-Row Kit for each row of collectors. A more complex divided system is shown in Figure 12. This also illustrates the application of the Row Spacer Kit to clear a roof obstruction.

BOOSTER PUMP SYSTEM In some cases, the pool filter pump may not be able to circulate water at a high enough flow rate to allow for proper collector operation. If so, it may be necessary to replace the filter pump with a larger one or add a booster pump. If the pump size is increased, it may also be necessary to upgrade the filter with one with greater flow ratings. For Supplemental Gas, Oil-Fired, or Electric Heaters, it is desirable to pipe the stand-by heater in a bypass loop. Refer to Figure 10. Fuel-fired heaters often create a large pressure drop. By placing a heater in a by-pass loop, pump size, and electrical energy requirements may be reduced.

SYSTEM START-UP AND TEST System Start-up and Checkout for Automatic Systems To check out the system for proper operation turn on the filter system. Set the temperature control to its highest level. Switch the control to the “flow through collector” mode. The “flow through collector” light should come on. The 3 way valve will then be sending water thru the collectors, and air will be purged out of the collectors into the pool return line for several minutes, and should then clear. The collectors should feel uniformly cool to the touch. Switch the control to the “bypass collector” mode. The corresponding light will go on and the 3 way valve will be sending water directly back to the pool, bypassing the solar collectors. After about 5-10 minutes, feel the solar collectors again. They should have begun to warm up. Now switch back to the automatic mode. If the sun is still shining on the solar collectors, the “flow thru collector” light should go on again. Adjust the temperature control lower. When you reach the actual temperature of the pool water, the light will turn off. The flow bypass collector light will go on again. Move the temperature control to maximum and leave there. The “flow through collector” light will go back on. For more detailed information on the system startup, trouble shooting and valve/control installation, follow the manufacturers’ instructions included with the automatic control system.
