AUTOMATIC DRAIN DOWN
- Both the solar
panel
s and the PVC pipe should be installed so the water will drain out of them when
the pump shuts off. A non-positive or solar 3-port valve is required for automatic drainage. This is especially important in
areas of the country where harsh winter conditions cause freezing conditions; however, the freezing point for solar
panels
starts at 40
degrees, so freeze damage can occur in virtually any area of the United States.
The Swim Joy solar pool
panel
s are warranted against internal freezing when installed to allow for drain down. If, as a result of a
unique roof design or adverse pool equipment locations (as demonstrated in figure
4
.1
below
), it is not possible to achieve complete
automatic drain down, manual drain down valves should be installed in appropriate places in the plumbing or at the end of the
bottom (feed) header.
Instead of installing an end cap (2-1
8
10-013) at the end of the header, you would install a manual drain down bib attachment set
(1-5115-021AS).
These valves should be opened when shutting down the system for the winter months or when freezing conditions are possible. Your
Swim Joy representative can assist you with the parts necessary for manual drain down installations.
