LP-199 REV. 4.15.14
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.
