Before Calling Your Dealer For Service
If The System Does Not Appear To Be Supplying Sufficient
Electrical Power:
Check for shading of the panels and consider seasonal or other explanations. If the issue remains
unresolved call your authorized FAFCO Inc. dealer.
If Your Concern Relates To The Heating Of Your Pool:
1. Has your filter been backwashed and are the skimmer and the pump basket clean?
2. Have you been refilling the pool with a lot of cold water lately?
3. Has the weather been marginal?
4. Have you been using your pool cover as instructed?
5. Are the panels operating "cool" to the touch on a sunny day?
If There Are No Initial Bubbles When Plumbing Turns On
Bubbles on start-up are caused because air in the system must be replaced by water from your
pool to cool your PV modules and heat your pool simultaneously. If no bubbles appear check the
following:
1. Ensure that the pump is running.
2. Check the isolation valve to make sure it is open.
3. Make sure the diverter valve is in the correct position.
Tiny Champagne Bubbles
If tiny champagne bubbles continue past the initial purging of the panels (3-5 minutes), this may
be an indication that the water circulation through the panels has been reduced. To ensure that
the system has proper flow check the following:
1. Has your filter been backwashed and are the skimmer and the pump baskets clean?
2. Check the isolation valve to make sure it is open.
3. Make sure the diverter valve is in the correct position.
If the bubbles continue with the solar turned off, check the piping leading to the pump for a suc-
tion side leak.
Some small bubbles may always be discharged into the pool due to the particular operating char-
acteristics of the individual system. They do not affect the operation of the system nor impair the
proper function of any other pool equipment.
