Once you are satisfied with the plumbing arrangement, go back and cement together all the joints that you have not
already cemented. Use good plumbing techniques and rags to protect the existing pool equipment.
NOTE:
Use pipe clamps the same size as the outside diameter of your plumbing fittings to secure the pipe and
fittings tightly to the wall.

NOTE:
W
hen cementing check valves, try to do so in a horizontal position to prevent cement from dripping into the
spring loaded valve and cementing it closed! When this is not possible, use cement sparingly and allow it to dry
slightly before inserting the pipe into the socket. When cementing to a 3-way valve, either remove the diverter from
the valve or cement with the diverter turned away from any open port to prevent the cement from running onto the
diverter cementing it in place!
For a truly professional looking installation, take time to clean the white PVC pipe. Use a clean rag, pour PVC cleaner on
it, and then wipe the dirt and identification marks off the pipe. Do this on all exposed pipe. This is also good preparation
if you plan on painting the pipe to match the house color.
IF YOU ARE INSTALLING AN AUTOMATIC SYSTEM:
The basic difference between the manual system just outlined and
an automatic system is the use of a motorized 3-way valve. This 3-way valve is operated by a differential control which
uses sensors to determine if the solar system is warmer or cooler than the pool water. This way, it can shut the solar system
off when cloudy conditions exist and thereby generate the optimum performance from the solar investment. It also
allows you to select a maximum pool water temperature so the solar system doesn’t overheat the pool. It accomplishes
this by the use of a sensor on the roof and a sensor installed into the pool plumbing. The directions included with the
automatic system components will direct you in the installation of the control and sensors. The 3-way valve will be
installed as described in above procedure.
