- Solar Controller
The solar controller controls the solar pump. It continuously monitors the temperature difference between the pool water & the Sunbather solar. Whenever the Sunbather solar is 7°c warmer than the pool water, the controller switches the pump on. The controller switches the pump off when the Sunbather solar has no heat to contribute to the pool. The desired pool temperature can be set by pressing the ‘Set Temp’ button and using the arrows to scroll through to the preferred temperature.
If the power to the solar controller is interrupted, eg. by time clock or power failure, the default setting when power is resumed is “ON” and “AUTO”, this will of course enable the solar pump to run. Be sure that water is available to the pump at all times during which power might be interrupted, otherwise damage to the pump may result.
- Vacuum Break Valve
This is installed in the return pipe from the Sunbather solar and allows air to enter the system after the solar system turns off, protecting the solar pipework against vacuum damage during hot weather. The valve usually makes a hissing noise when operating and may lose a small amount of water during operation.
- Fine Tuning
The sound of cascading water on the solar return line would indicate the need to further restrict the opti valve referred to overleaf. Do not close it completely, but just sufficient to stop bubbles returning to the pool. Contact your nearest Sunbather office for assistance if required.
- Handy Hints
We recommend that a Sunbather Thermal Cover be used throughout the season to ensure maximum heat retention in the pool and a further extension of the effective swimming season.
- On the spot repairs
If the solar tubing is accidentally pierced and is leaking, it is easy to repair using the enclosed repair kit. Simply cut through the point of leakage with a sharp blade and repair with the plastic barb and sleeves as shown in the instructions included or contact your nearest Sunbather office for assistance.
- Water treatment
Once any form of heating is installed for a pool, the chemical treatment will change. With the water up to 100c warmer, the Ph and chlorine levels of the pool water should be regularly checked. Water will shift out of adjustment with noticeable results, so it is important to change test kit chemicals at the start if each season as they do deteriorate.
- Filters
If your solar pump has a lint pot or there is a solar filter in your solar pipework, ensure they are cleaned regularly.
