Special System Layouts

Use a divided system when installing more than the rec-

ommended maximum number of collectors per row,

when avoiding roof obstructions, or where limited space

dictates.

This provides uniform distribution of water

through all the collectors. If water distribution through the

collectors is non-uniform, the heating capacity of the sys-

tem will be reduced.

WHEN INSTALLING A DIVIDED SYSTEM, THE OUT-

LET HEADERS FROM EACH OF THE LOWER (OR

CLOSEST) ROWS OF COLLECTORS MUST BE CON-

NECTED TO THE HIGHEST (OR FURTHEST) POINT IN

THE SYSTEM. Refer to Figure 11.

A divided system requires an Add-A-Row Kit (Part

#12043-1/-2) for each row of collectors.

A more complex divided system is shown in Figure 12.

This also illustrates the application of the Row Spacer Kit

to clear a roof obstruction.

Booster Pump System

In some cases, the pool filter pump may not be able to cir-

culate water at a high enough flow rate to allow for proper

collector operation. If so, it may be necessary to replace

the filter pump with a larger one or add a booster pump. If

the pump size is increased, it may also be necessary to

upgrade the filter with one with greater flow ratings.

Supplemental Gas, Oil-Fired,

or Electric Heaters

It is desirable to pipe the stand-by heater in a bypass

loop. Refer to Figure 10. Fuel-fired heaters often create

a large pressure drop. By placing a heater in a by-pass

loop, pump size, and electrical energy requirements may

be reduced.

SYSTEM START-UP AND TEST

System Start-up and Checkout for

Automatic Systems

To check out the system for proper operation turn on the

filter system. Set the temperature control to its highest

level. Switch the control to the "flow through collector"

mode. The "flow through collector" light should come on.

The 3 way valve will then be sending water thru the col-

lectors, and air will be purged out of the collectors into the

pool return line for several minutes, and should then clear.

The collectors should feel uniformly cool to the touch.

Switch the control to the "bypass collector" mode. The cor-

responding light will go on and the 3 way valve will be

sending water directly back to the pool, bypassing the

solar collectors. After about 5-10 minutes, feel the solar

collectors again. They should have begun to warm up.

Now switch back to the automatic mode. If the sun is still

shining on the solar collectors, the "flow thru collector"

light should go on again. Adjust the temperature control

lower.

When you reach the actual temperature of the pool

water, the light will turn off. The flow bypass collector

light will go on again. Move the temperature control to

maximum and leave there. The "flow through collector"

light will go back on. For more detailed information on

the system startup, trouble shooting and valve/control

installation, follow the manufacturers' instructions includ-

ed with the automatic control system.
