Trouble Shooting
A properly maintained solar water heating system can provide years of dependable trouble free service. It is
suggested that routine preventive maintenance program be established and followed by the end user with his
contractor. Listed below is the maintenance check list that outlines the primary components of the solar system that
need to be inspected annually. See page 37 for additional information.
1. Propylene glycol – It is very important that the quality of the propylene glycol heat transfer fluid is
maintained to avoid damage to the collector loop and related components which come in contact with the
fluid. See the propylene glycol Data Sheet located in the back of the manual for further details.
2. Water quality can affect the operation of the solar heat exchanger over time. In very hard water areas, it is
recommended you drain a few gallons of water from the storage tank to keep the bottom of the tank free
of sediment.
3. Inspect and clean the solar collectors of any dirt, leaves, debris or film that may have settled on the surface
and may affect the performance. Clean by spraying with a pressurized water hose only.
4. Check Insulation for deterioration.
5. Check solar tank sensors and the collector sensor to assure that they are secure and have not moved or
loosened.
6. Inspect the T&P valve on the water heater. Lift the release handle lever and make discharge is directed to
an open drain. Always remove sediment from tank prior to testing T&P valve.
7. The area near the water heater must be kept free of flammable liquids such as gasoline, paint thinners,
adhesive or other combustible materials.
8. Anode rod Inspection – The anode rod should be removed from the water heater tank annually for
inspection. It is important to turn off the power to the heater and run water until it is cold, then drain tank
and replace the anode rod. See page 52 for additional information.
Shut down procedures
The solar system is designed to be easily isolated for emergency repairs or routine maintenance. To isolate the
water heater, simply shut down the supply water shut off valve which isolates the water heater from the
pressurized cold water supply. The collector loop can be isolated from the solar storage tank by closing the collector
array “hot” and “cold” line isolation valves. If the pressure in this loop drops or you find a glycol leak, close these
valves and turn the circulating pump off by shutting down the power to the control, then contact your installation
contractor.
