AUTOMATIC DRAIN DOWN
- The collectors and the
CPVC/PVC pipe should be installed so the water will drain
out of them when the pump shuts off. This is especially
important in areas of the country where freezing
conditions occur.
The eco-SPARK 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 eco-SPARK representative
can assist you with the parts necessary for manual drain
down installations.
