PROBLEM
SOME OF THE
SOLAR PANELS
ARE WARM TO
THE TOUCH WHILE
OTHERS ARE COOL
TO THE TOUCH
Installation Manual
CAUSE
1. There is not equal flow
through all of the panels.
Warm panels indicate low
water flow. Pump issue.
2. There is not equal flow
through all of the panels.
Warm panels indicate low
water flow. Install issue.
SOLUTION
A. Be sure filter is clean.
Backwash to reduce
pressure.
B. The pump may not be
providing enough water to
the solar system. Check
water flow using a flow meter.
Increase pump horsepower
if needed to maintain
recommended flow.
C. If there is a suction type
cleaner in the pool, remove it.
If this eliminates the problem,
use it only when the solar
system is off.
A. If the system is a single
row array and there is
adequate flow, use the (HBV)
on the return line to throttle
the flow back to produce
more back pressure on the
system. This will even out
the flow through the panels.
If the array contains more
panels than the maximum
recommended on page 7 of
this manual, change the array
to a double row or single row
split feed as show in (Fig. 6.2
and 6.3).
B. If the system is a double
row or a single row split feed
array and there is adequate
flow, install a ball valve on
the return side of the set of
panels that are the coolest
to the throttle. Back the flow
through these panels and
force more water through the
warmer panels. If any section
of the array contains more
panels than the maximum
recommended on page 9 of
the manual, make changes as
needed to correct this.
