Before Calling Your Service Provider
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 (if equipped)?
5. Are the collectors "cool" to the touch while operating on a sunny day?
If There Are No Initial Bubbles When Plumbing Turns On:
Bubbles on start-up are caused by air in the system being replaced by water and indicate opti-
mized performance. 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 after the initial purging of the collectors (3-5 minutes), this
may be an indication that water circulation through the collectors has been reduced. To ensure
that the system has proper flow check the following:
1. Has your filter been backwashed?
2. Are the skimmer and the pump baskets clean?
3. Check the isolation valve to make sure it is open.
4. 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.
