Plumbing Requirements
It is important that the pool and spa plumbing system be in accordance with local codes and the
Recommended Hydraulic Schematics (page 4 and 5). Before starting, please review the diagrams
and the following recommended guidelines:
The spa should be at or above the level of the pool.
If the spa is attached to the pool, provide a dam between the two bodies of water to allow the spa
to overflow into the pool. If the spa is not attached to the pool, an overflow, sufficient in size to
carry a full pump-flow, must be installed at the water level in the spa.
Plumb a three-port Intake Valve on the suction-side of the filter pump, so that the center port of
the valve is connected to the pump inlet. Connect the spa suction to one side of the Intake Valve,
and the pool suction to the other side.
Plumb a three-port Return Valve on the return-side of the heater, so that the return water will
enter the valve through the center port.
Connect the spa return to one side of Return Valve, and the pool return to the other side.
If required, install a spa makeup line (consisting of a manual gate or ball valve, for elevated spas
install a check valve) to bypass the pool return line. This will enable some of the chemically-
balanced water from the pool to cycle through the spa. The manual valve will allow the amount of
bypass to be adjusted.
If the spa is to be constructed in concrete, special provision should be made at this time for the
installation of the Spa-Side remote control.
Select a convenient location in the deck or above water level in the spa wall (where the
Spa-Side remote will not be submerged by the spa water), and install a 6 in to 12 in length of
one inch PVC pipe to provide a receptacle for the Spa-Side remote. The pipe should be level
and protrude beyond the finished surface of the spa. It will be cut back later at installation time.
Reduce the pipe size down to ½ in or ¾ in conduit, and run it to the proposed Load/Power
Center location at the equipment pad. Use sweep elbows for turns.
The Spa-Side remote will not be installed until the spa construction is completed.
For systems which incorporate a skimmer, it is possible to balance the amount of suction
between the skimmer and main drain for maintenance purposes. This is easily accomplished by
installing a manual three-port mixing valve at the suction line. Plumb one port to the skimmer and
the other to the main drain.
If a “non-booster pump” pressure-side pool cleaner is being used, plumb a manual three-port
valve between the filter pump and filter, with the third port plumbed to the pool cleaner line, and
install a motorized two-port Pool Cleaner Valve at this line. The motorized valve will
automatically open whenever the Control System activates the pool cleaner.
If a booster pump pool cleaner is being used, plumb the booster pump so that its suction-side is
connected to the pool return, after the heater, and as close to the ground as practical.

EasyTouch Load Center Installation Guide
Recommended Hydraulic Schematic for Shared Equipment System
Plumb the solar feed and return lines between the filter and the heater. Install a three-port valve
at the feed line. Use a solar valve (model SOL-2T), to allow automatic draining of the panels.
A solar booster pump should be used when the distance to the panels exceed 200 ft., or the
panels are elevated higher than 25 ft.
Glazed solar panels require a drain valve (model HW-5B) to allow draining of the panels. This
prevents damage from overheating water. Install a drain valve at the solar feed line and connect
to the pool fill line.
SCG systems only: IntelliChlor cell with check valve between the heater and valves. Refer to
IntelliChlor User’s Guide (P/N 520589) page 4 for plumbing requirements.
Equipment Location
All equipment, with the exception of the spa-side remote, must be located at least 10 ft. from the
water’s edge.

Sensor cable is 3 feet long and the Water Temperature Sensor is 25 feet long.
• Mount the EasyTouch load center on a flat vertical surface or wall so that the conduit
knockouts are located at the bottom of the enclosure. Upper and lower brackets are
provided to mount the enclosure to a vertical surface.
• DO NOT mount the EasyTouch load center enclosure horizontally. Water can enter the
conduit knockouts and cause damage to the system and an electrical shock hazard.
• Consider the EasyTouch load center location when routing the conduit carrying the AC
power to the EasyTouch load center, and the conduit that will be run to the high voltage
equipment.
• Install the EasyTouch load center so that drainage is provided for all electrical components.
• Motors should have built-in thermal protection.
• Allow for unobstructed access to the front of the EasyTouch load center for the owner or
service personnel.
