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. Hand tighten then 1/4 to
1/2 snug tight with pliers. Water IN on
the RIGHT, Water OUT on the LEFT.
PLUMB AFTER the FILTER & BEFORE
any CHLORINATORS or CHEMICAL
FEEDERS
2. FREEZE CONDITION PLUMBING. See WINTERIZING PROCEDURES on page 7.
3. 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.

4. 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.
5. POOL/SPA COMBINATIONS W/SPILL-OVER
Use this diagram for
a connected pool and
spa, where the spa has
a spill-over type wa-
terfall into the pool.
Where one pump and
one heater are used for
both the pool and spa.
If the water pump ex-
ceeds 1.5 H.P. then in-
stall a external bypass
as shown on page 5.
