AUTOMATIC DRAIN DOWN
- The collectors and the PVC
pipe should be installed so the water will drain out of
them when the pool shuts off. This is especially important
in areas of the country where freezing conditions occur.
The Heliocol solar pool collectors 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, 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 (2-1410-013) at the
end of the header, you would place a (2-1410-005) type
connector (2-1410-004) 1½” x 1½” THD PVC reducer
bushing along with a ½” boiler drain (1-5115-017)].
These valves should be opened when shutting down
the system for the winter months or when freezing
conditions are possible. Your Heliocol representative
can assist you with the parts necessary for manual drain
down installations.
