C. PLUMBING & WATER CONNECTIONS
1. BASIC PLUMBING. For a pool only or spa only, install the plumbing piping as shown:
Connections from factory are 2" unions (included). Water IN on the RIGHT, Water OUT on
the LEFT.

2. CHOLORINATOR. Be sure to install a CHEMICAL TRAP LOOP as shown. The loop should
be at least 6 to 8 inches above the chlorinator/feeder top to prevent chlorine backup into the heater
when the water pump is off. All feeders should be installed at the same or below the heater piping
elevation to prevent chemical back up into the heater.
DO NOT install the heater down stream from any chemical feeders.
DO NOT allow chemical feeders on the suction side of the water pump.
DO NOT allow any chemicals or chlorine to be fed through the skimmer.
DO NOT allow the pool water pH to go below 7.4.
DO NOT allow the alkalinity to go below 90 p.p.m.
DO NOT allow the chlorine to go above 5 p.p.m. for extended periods. Chemical damage is not
covered by warranty.
3. FREEZING CONDITION PLUMBING
freezing conditions exist, the heater must be plumbed as shown so it
can be winterized. Water left inside the heater will freeze and cause
damage. Plumb in a union, shut off valve, a boiler drain and a air petcock
valve on the water in and water out lines as shown here. Isolate the
heater with the shut off valves and use pressurized air to clear the heat
exchanger of all water. In areas where freezing conditions are temporary,
the water pump should be set to run 24 hours to prevent freezing. Freeze
damage will void warranty.
4. BYPASS FOR FLOW RATES OVER 70 G.P.M. Typi-
cally the automatic internal water bypass can handle up to a
1.5 H.P. water pump or 70 G.P.M. If the water pump exceeds
1.5 H.P. then install either of the optional bypasses as shown
below. The installation of a flow meter on the WATER OUT
line is suggested. Adjust the bypass to divert a minimum of
40 to 50 G.P. M. through the heater. Flow meters should be
installed per the manufacturer's instructions.

5. MULTI UNIT WATER CONNECTIONS

Plumb multiple units as shown below. Use flow meters on each
WATER OUT line if two or more units are plumbed together.
Use ball valves to balance the water flow through each unit.
Using T's, caps and a minimum 6 inch pipe extension on the
plumbing manifold will help equalize the water flow better than
90˚'s. Flow meters should be installed per the manufacturer's
instructions.
