WARRANTIES AND DISCLAIMERS ............................29 MAINTENANCE NOTES .................................. 37 HTP CUSTOMER INSTALLATION RECORD FORM ........................38 INTRODUCTION Your solar water heater has an internal solar heat exchanger for use with solar collectors. When there is not sufficient solar energy, the water heater utilizes a backup system to provide hot water.
Improper installation or use may result in property damage. Such damage IS NOT covered by warranty. NOTE: HTP DOES NOT WARRANT THIS WATER HEATER AGAINST FREEZE RELATED DAMAGE. ALL PIPING AND PLUMBING CONNECTIONS IN CLOSED LOOP SYSTEMS SHOULD BE MADE WITH COPPER PIPE ONLY. No less than ¾”...
A. SCOPE OF MANUAL This manual pertains only to the installation and operation of the HTP SuperStor Ultra solar water heater. Details for the installation, operation, and maintenance of the complete solar water heating system, including, but not limited to: the solar collector(s), boiler, pump, system controller, valves, and other plumbing components, should be provided separately by their respective manufacturers.
Please refer to glycol manufacturer’s specifications about the temperature ranges the liquid can withstand. Only food grade propylene glycol, FDA rated as GRAS, should be used. NOTE: HTP DOES NOT WARRANT THE SOLAR WATER HEATER AGAINST FREEZE-RELATED DAMAGE. PART 3 - GENERAL SOLAR INFORMATION A.
Pressurized Closed Loop Systems – These systems use a glycol/water mix as HTF, which protects the system from freezing. These systems operate at high pressures. In systems using a glycol/water mix, freeze protection fluid must be non-toxic propylene glycol, FDA rated as GRAS. To protect the heat exchanger and other system components, regular scheduled maintenance must be established to monitor and maintain proper HTF pH levels.
D. COLLECTOR ANGLE, PLANE, AND DIRECTION 1. COLLECTOR DIRECTION The collector should face the equator. In the northern hemisphere, this is due south, and in the southern hemisphere, due north. Facing the collector in the correct direction and angle is important to ensure optimal heat output.
F. COLLECTOR LOOP PIPE INSULATION The collector loop supply and return lines must be well insulated with high quality, flexible, closed cell insulation to minimize heat loss. Wall thickness of pipe insulation should not be less than ¾". 1" wall thickness is required in all areas prone to annual hard freeze conditions.
M. SNOW LOAD In areas prone to heavy snowfall, the solar collector(s) should ideally be installed at an angle of 50 or greater to help promote snow sliding off the collectors. In addition, it is advisable to raise the lower collector frame off the roof surface 6 – 8 inches or higher. Doing this places the collector above moderate snowfall accumulation and allows drifting snow to more easily slide out from under the collector, which helps ensure that snow does not cover the collector array.

SOLAR WATER HEATER LOCATION To minimize expense and heat loss, locate the solar water heater as centrally to the domestic piping system and near the solar collectors as possible.
Chemical imbalance of the water supply may affect efficiency and cause severe damage to the water heater and associated equipment. HTP recommends having water quality professionally analyzed to determine whether it is necessary to install a water softener. It is important that the water chemistry on both the domestic hot water and central heating sides are checked before installing the water heater, as water quality will affect the reliability of the system.

When making a connection to the heat exchanger, use Teflon Tape and joint compound to prevent leaks. The connections to the heat exchanger are 1” NPT. Do not apply heat directly to the heat exchanger thread connection when sweating fittings. Line pressure and temperature gauge shall be installed in the collector supply and return lines to allow for a simple diagnostic check of proper system operation.

Circulator (#13) Circulates the HTF from the solar collector into the solar heat exchanger. Drain Valve (Tank) (Valve #14) Flushes sediment which may accumulate on the bottom of the solar water heater and also provides a means of draining the tank. Tank Sensor Is wired to the solar controller to measure the temperature on the bottom of the solar water heater in conjunction with the solar collector sensor.

To assure the correct flow through the boiler back-up heat exchanger, refer to Figure 10 to correctly size the circulator to the boiler or auxiliary heat exchanger. HTP recommends a flow rate of 1 gpm for every 10,000 BTU based on a 20 F temperature difference between the supply and return of the heat exchanger.
M. ELECTRICAL CONNECTION (SE MODELS ONLY) Tank must be full before unit is turned on. The heating element will be damaged if energized for even a short period of time while tank is dry. This damage IS NOT covered by warranty. Be sure to ground the water heater.
N. THERMOSTAT ADJUSTMENT The thermostat is located in the front of the heater. The access cover must be removed to adjust the factory default setting of 119 This temperature is satisfactory for average household use. If an adjustment is necessary, turn off the power to the heater, remove the black access cover and insulation. The thermostat protective cover should not be removed.
NOTE: HTP DOES NOT WARRANT THE SOLAR WATER HEATER, SOLAR COLLECTOR, OR ANY COMPONENTS AGAINST FREEZE RELATED DAMAGE. PART 8 – START-UP PREPARATION DO NOT MOVE ON TO THESE STEPS UNTIL THE ENTIRE SOLAR SYSTEM, INCLUDING ALL PIPING, SOLAR COLLECTORS, SENSORS, PUMP, CONTROLS, AND ELECTRICAL CONNECTIONS, ARE PROPERLY SECURED, INSULATED, LABELED AND INSTALLED.
If the heating element needs replacement, it is VERY important to use the same voltage, wattage, and construction. This element must be stainless steel and the hex plug be made of brass. This replacement part is available from HTP and should not be purchased from outside sources.
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.

VISCOSITY: The HTF viscosity over the service temperature range is based on a specific gravity 15/15 C (60/60 F) 1.053-1.063. DOWFROST inhibited glycol-based fluid has an effective operating temperature range of -50 F to 250 F. At temperatures below -50 increased viscosity (>1,000 centipoise) can make use of DOWFROST impractical unless larger pumps are installed.
