LOCATION
The heater requires water flow and pressure to
operate properly. It must therefore be installed
downstream of the discharge side of the filter and
pump. A typical installation is plumbed as follows:
1. The Pump outlet is plumbed to the inlet of the Filter.
2. The outlet side of the Filter is then plumbed to the
inlet of the Heater.
3. The outlet of the Heater is plumbed to the return line
to the pool or spa. The Pump, Filter and Heater are
plumbed in series.
Plumbing from the heater back to the pool must not
have any valves or restriction that could prevent flow
when the pump is operating.
Use the pressure loss chart below to specify a
suitable pump.

Heater must be located so that any water leaks will not
damage the structure of adjacent area. High tem-
perature 2" plastic pipe (CPVC) may be threaded
directly into the Cast Iron header flanges. This is not
the same as the Schedule 80 PVC pipe which is also
coloured grey. PVC may be used immediately after
the CPVC adapters.
NOTE:
If operating pressure above 2 bar (30psi) are
encountered then connection pipes must either be
screwed into the flange or suitably anchored.
CAUTION:
NEVER install PVC directly into Cast Iron
header flanges.

*When flow rates exceed maximum an external
auxiliary bypass valve is required. See external
bypass valve section for details.
COMPANION FLANGE CONNECTIONS
DO NOT
use petroleum base assembly fluids (such
as Petroleum Jelly or lubricating oil). If assembly lube
is required, use a silicone grease.
055 Model Only
The inlet/outlet header flange accepts a 1
½"
copper tube or 1¼" galvanized pipe as a slip
connection directly into the manifold. The flange is
also threaded for 1½" pipe thread.
