NOTE: Some jurisdictions require the addition of a flow
switch on ASME installations. Kit # 015889F for flange
connection or 015890F for NPT connection can be
ordered that will allow a standard ASME unit to comply
with the code requirements.
ProTek Shield Assembly
This heater is equipped with a ProTek Shield Assembly
(located under the inlet connection on polymer headers)
and in the ProTek Shield Adapter assembly shipped loose
in the accessory carton for field installation on brass ASME
headers.
NOTE: ProTek Shield not available on ASME models
until March 2020.
This component provides protection to the heat exchanger
against galvanic corrosion, when properly bonded to the
heat exchanger. It should be replaced when the weight of
the ProTek Shield is reduced to about 40% of the original
weight (1.46 #).

A A CAUTION: STOP the pool pump before attempting to
remove ProTek Shield Assy. Failure to do so may result
in damage to ProTek Shield Assy, loss of pool water, or
personal injury.
CAUTION: Do not use tools to remove (twist) the
ProTek Shield Assy or the wing nut on the stud of the
ProTek Shield Assy. Non-warrantable damage may
occur.
Polymer Headers (Residential Models)
Before attaching the 2-inch unions to the inlet/outlet
header, make sure the O-rings are properly seated in
the grooves. Use Aqualube or equivalent non-petroleum-
based lubricant on the O-ring. Hand tighten the unions .
Glue PVC piping directly to the unions.

High temperature CPVC header flanges and header
flange nuts are provided. If there is any possibility of back-
siphoning when the pump stops, it is suggested that a
check valve (or valves) also be installed in the system.
Brass Headers (ASME Models)
Heater must be located so that any water leaks will not
damage the structure of adjacent area. Before attaching
the ProTek Shield Adapter to the inlet connection and the
2-inch unions, make sure the O-rings are properly seated
in the grooves. Use Aqualube or equivalent non-petroleum-
based lubricant on the O-ring. Hand tighten the unions .
Glue PVC piping directly to the unions.
