Before Installing Your System

Some simple dos and don'ts!

1. Heat rises even in a hot attic. Locate the PCS1 as high in the attic as is
practical.

2. Airflow through the PCS1 is important. Do not obstruct air going in or out of
the unit.

3. Recirculating air in the attic works well for heat transfer. Locate the PCS1
within the middle 1/3 of the attic. Do not locate near an end wall.

4. Heat is drawn into the coil and cooler air is discharged from the fan. If the
PCS1 is located slightly off center along the attic ridge, make sure the coil side
of the unit is facing the larger portion of the attic.

5. Suspending the PCS1 supporting platform using chains will minimize noise
amplification caused by wood trusses. Therefore, do not rigid mount the PCS1
to the roof structure in areas where noise is a concern.

6. The attic sensor can be cooled by the air discharge of the PCS1. Locate the
attic sensor at the peak of the attic and out of the airflow of the unit.

7. The pool water sensor can be influenced by the sun and rain. Shelter the pool
water sensor as much as is possible. It can even be insulated if necessary with
fiberglass or other materials.

8. The ground can "SINK" heat away from pipes going to and from the PCS1.
INSULATE OR WRAP ALL UNDERGROUND PIPES SO DIRT (GROUND)
DOES NOT CONTACT THE PIPES DIRECTLY.

9. Do not over tighten the wing nut on the relay for the Auto or Auto Plus
systems. It can cause the relay to malfunction.

10. The mechanical stress caused by unsupported pipes can crack glued pvc slip
joints. Support all pipes in and outside the attic with straps or C-clamps that
keep the weight of the pipes off of all joints and union connections.

INSTALLATION PROCESS

[BASIC]

1. Retrofit support system with new valves

2. Install the PCS1

3. Automate the PCS1

The installation discussions that follow will amplify this basic installation process and

provide plumbing and electrical details. NOTICE:It may be necessary to modify the diagrams

supplied depending upon local installation requirements including code restrictions. The installer is

responsible for making these determinations. The most difficult part of the installation is the first

step -- retrofitting the pool’s support system.
