CONNECT WITH THE FILTRATION SYSTEM
1.
Study the plumbing after the filter and decide where you are going to install the union
check valve and the “T” fitting for the solar system entrance. If you have auxiliary
equipment, you may need to re-plumb a portion of your existing plumbing so this
equipment is located after the eco-Spark® system.
2.
Cut the pipe after the filter where you have decided to locate the union check valve and
where your solar return pipe will attach to your existing pool return line.
3.
As mentioned earlier, it is a good idea to assemble all pipe and fittings before connecting
them just in case you make an error. Install a union check valve on the pipe coming out
of the filter. Be sure that the arrow showing flow direction is pointed
away
from the
filter.
4.
The 3-way-valve is installed next. Before installing this valve it is recommended to drill a
6 mm (0.2") hole inside the valve partition in order to enable water expansion due to
stagnation pressure.
It may come right next to the check valve, or you may have to use
some pipe and fittings to locate it off the main line. (As stated earlier, use as few 90°
elbows as possible.)
5.
Install the ball valve to the solar feed coming out of the 3-way-valve.
6.
Install the vacuum breaker about 2m up the feed line using a "T" connector or saddle
weld on, and threaded ¾’’ elbow. Face the "T" to the outside as shown. Wrap the
threads of the vacuum Breaker with "Teflon" tape and screw it into the threaded reducer
bushing.
7.
Install the second ball valve to the solar return line.
8.
Now determine where to locate the "T" fitting. The "T" may be located right next to the
3-way-valve or elsewhere depending on your system. Connect the "T" fitting first to the
solar return line, then to the 3-way-valve, and then to the pool return line.
9.
Once you are satisfied with the plumbing arrangement, go back and cement/weld
together all unsealed joints.
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:
When 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 2 and 3-
way- valves 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 and cementing it in place! In
cooler climates glue dries much slower.
