PLUMBING CONNECTIONS

CAUTION
Before operating the heater on a new installation, turn
on the circulation pump and bleed all the air from the
filter using the air relief valve on top of the filter. Water
should flow freely through the heater. Do not operate
the heater unless water in the pool/spa is at the proper
level. If a manual by-pass is installed, temporarily close it
to insure that all air is purged from the heater.
