The collector loop can be isolated from the solar storage tank by closing (#6 and #11). If the pressure in this loop drops, or you find a
glycol leak, shut these valves and contact your installation contractor. Turn the circulating pump off on your solar control.
B. VACATION SHUTDOWN
Solar water heaters can build up very high temperatures when there is no daily draw on the system. The best way to dissipate heat in
the system is set the control to run the circulator pump 24 hours a day to cool off the storage tank at night. The collector will radiate
heat back to the atmosphere at night, preventing the system from stagnating at very high temperatures.
C. ESTIMATED LIFE OF COMPONENTS
Proper care and maintenance will determine the life expectancy of the individual components of the solar system. Refer to
manufacturer’s warranty information to determine coverage of individual components. To obtain warranty service, call your local service
or installing contractor.
D. TEMPERATURE AND PRESSURE RELIEF VALVE
A temperature and pressure relief (T&P) valve is designed for emergency safety relief and shall not be used as an operating control. A
T&P valve functions by discharging water in an emergency. Therefore, it is essential that a discharge line be piped from the valve in
order to carry the overflow to a safe place of disposal. The discharge line must be the same size as the valve outlet, must pitch
downward from the valve, and terminate at least 6” above a drain where any discharge will be clearly visible.
Following installation of the T&P Relief Valve, the valve lever MUST be operated AT LEAST ONCE A YEAR by the water heater
owner to ensure that waterways are clear. Certain naturally occurring mineral deposits may adhere to the valve, blocking waterways
and rendering the valve inoperative. When the lever is operated, hot water will discharge if the waterways are clear. PRECAUTIONS
MUST BE TAKEN TO AVOID PERSONAL INJURY FROM CONTACT WITH HOT WATER AND TO AVOID PROPERTY DAMAGE.
BEFORE operating lever, check to see that a discharge line is connected to the valve, directing the flow of hot water from the valve to a
proper place of disposal. If no water flows when the lever is operated, replacement of the valve is required. TURN THE WATER
HEATER “OFF” AND CALL A PLUMBER IMMEDIATELY.
PART 10 - TROUBLESHOOTING
Owners are advised to contact the installer whenever in-depth interaction with the solar system is required.
A. LEAKS
For leaks in the potable water system or solar storage tank, close the cold water inlet and unplug the solar controller. This will isolate
the solar system until repairs can be made.
B. OTHER PROBLEMS
A noisy pump could be an indication of worn bearings, obstructions, or a leak in your system. Call your installer for diagnosis of the
problem, repair of the system, and/or replacement of components.
For your safety, DO NOT attempt repair of electrical wiring, thermostat, heating element or other operating controls. Refer repairs to
qualified service personnel.
C. OPERATING SUGGESTIONS FOR THE USER
A properly designed solar hot water system provides solar energy for approximately 70 – 90% of annual hot water needs. Listed below
are some suggestions that will maximize the benefits of your solar hot water system.
1. Showers - If possible, take showers during the day, or in the early evening. Use low flow showerheads to reduce water
consumption.
2. Dishwashing – Run your dishwasher during the day, after showers, to ensure as much hot water as possible is available for
showers.
3. Laundry – Spread clothes washing over the week instead of washing all at the same time.
4. Single Lever Faucets – When using cold water, make sure the lever is all the way over in the cold position. This prevents hot
water from inadvertently flowing from the solar storage tank.
