CONNECTING TO THE POOL EQUIPMENT (CONTINUED)
6.
Plumb the solar feed line to one of the ports on the 3-way diverter valve.
A two-way isolation valve should also be plumbed into the feed line after
the diverter valve in an accessible location at the pool equipment area.
7.
If installing the vacuum relief valve on the feed line, a PVC tee and ¾” threaded reducer
bushing should be plumbed into the feed line at least 8 ft above grade level (I.E. beneath
the roof overhang prior where the piping transitions to the roof). Wrap the threads
of the vacuum relief valve with Teflon tape and screw into the reducer bushing.
NOTE: The vacuum relief valve may also be installed at the collector bank.
The end cap on the upper manifold may be replaced by a CPVC connector
with a ¾” female threaded adaptor to accept the vacuum relief valve.
NOTE: If not installing the vacuum relief valve on the supply line a tee should
still be installed with a threaded reducer bushing to facilitate pressure testing.
A ¾” threaded plug should be used when the system is operating.
8.
Install a tee fitting on the pipe going back to the filter. One port should be connected
to the remaining port on the three-way diverter valve. The remaining port should be
connected to the return line from the solar collectors.
9.
A two-way isolation valve should be plumbed into the return line and should
align with the isolation valve on the feed line so both may be easily accessed.
