Imprimir páginarelief valve(s) and replace it with and end cap. Relocate
a vacuum relief valve to a position in the inlet piping
which is at a height of approximately three-fourths of the
elevation of the collectors above the pool.
Figure 1.
(A quicker alternate method is to first try to reverse the
end cap and the vacuum relief valve on the collector
array to see if this stops the bubbles in the return lines.
Sometimes the end cap is about 3/4 of the elevation of
the collectors and this is a lot quicker than cutting in a tee
in the supply pipe.)
MAINTENANCE
Winterizing Procedures
The solar collectors should drain automatically each time
the pump cycles off. There are no special requirements
for winterizing the solar collectors.
should be winterized as per your normal practice. In
southern parts of the country pool owners operate their
pools throughout the winter although light freezing condi-
tions may occur. The accepted procedure for avoiding
freezing of the pool piping and filtration system has been
to continuously circulate the water. When solar heaters
are used on a pool under these conditions, anti-freeze
precautions should be taken. Aquatherm Industries solar
collectors are not normally affected by light freezing.
However, in order to protect appurtenant components
such as end caps and pipe fittings and the collectors
against unusual or severe freezing conditions, one of the
following two procedures should be followed when freez-
ing weather is imminent.
1. Turn circulating system off and allow solar collectors
and piping to drain. Isolate collectors with gate or ball
valve in collector feed line and a check valve in the col-
lector return line. Switch the solar control to the bypass
position. The pool filtering system may then be turned
back on. When freezing conditions have passed, open
isolation valves and switch the solar control to "AUTO".
2. Switch the solar control to the "COLL" position so that
water circulates through the collector. When freezing con-
ditions have passed, switch the solar control to "AUTO".
THIS METHOD IS NOT RECOMMENDED WHERE
TEMPERATURE LEVELS MAY DROP SEVERELY.

Annual Service
Collector Clamps:
In particularly hot climates, such as Arizona and
Southern Florida, the clamps which are used to connect
the solar collectors may become loose. If you notice
leaks around the hose couplings, use a nutdriver to tight-
en clamps. Do not tighten to the extent that the pipe col-
lapses or the clamp gears strip. In areas where unusu-
ally high stagnation temperatures are prevalent or where
abnormally high system pressures occur, use header
insert (Part #50055-1/-2).
COLLECTOR REPAIR
This method allows for an easy and permanent on site
repair of a collector by isolating the leaking riser tube.
Referring to the figure below, locate the tube to be isolat-
ed. (End tube has been shown for clarity.) Using a sharp
utility knife, very carefully cut away approximately 1" of
the tube at both headers. Drive a #10 - #12 sheet metal
screw, preferably stainless, into the hole in the header.
The screw must be between 1/2" and 3/4" long. DO NOT
OVERTIGHTEN! If the screw strips out, or if the repair
leaks, use a larger screw. This repair method will not
void the collector warranty.
