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.
