Water Connections - STA-RITE 200K BTU/HR Owner's Manual

WATER CONNECTIONS

The heater requires proper water flow and pressure for its
operation. See Figures 15 and 16 for the recommended
installation. The filter pump discharges to the filter, the fil-
ter discharges to the heater, and the heater discharges
directly to the pool or spa.
A manual bypass valve should be installed across the
heater when the pump flow exceeds 120 GPM. See
instructions below for setting of the manual bypass.
Make sure that the outlet plumbing from the heater con-
tains no shut-off valves or other flow restrictions that could
prevent flow through the heater (except as noted below).
To switch flow between the pool and spa, use a diverter
valve. Do not use any valve that can shut off the flow.
Do not use a shut-off valve to isolate the heater unless it is
below the level of the pool or spa.
Install a check valve if there is a possibility of back-siphon-
ing through the heater when the pump is off.
NOTICE: Improper operation of chemical feeders can
cause severe damage to the heater which is not covered by
the warranty. Either equip chemical feeders with an anti-
siphon device to prevent chemicals from siphoning into the
heater if the pump shuts off, or install the chemical feeder
downstream of the heater.
WATER PIPING
Connect the heater directly to 2" PVC pipe, using the inte-
gral unions provided. The low thermal mass of the heater
will prevent overheating of the piping even if the pump
shuts down unexpectedly. Heat sinks are not required.
