WARNING

Improper installation, adjustment, alteration,

service or maintenance can cause serious

injury or property damage. Refer to this

manual. For assistance or additional

information, consult a qualified installer or

service agency.

CAUTION

The recommended temperature for normal

residential use is 120°F. The dial on the

aquastat does not always reflect the out-

coming water temperature, which could

occasionally exceed 120°F. The variation in

out-coming temperature could be based on

factors including but not limited to usage

patterns and type of installation. Test your

water at the tap nearest to the water heater.

WARNING

Hotter water increases the risk of scald injury.

Before adjusting the water temperature setting,

read this instruction manual. Temperatures at

which injury occurs vary with the person’s age

and the length of exposure.

The slower reaction time of children, elderly,

and physically or mentally challenged persons

increases the scalding hazard to them. It is

recommended that lower water temperatures

be used where these exposure hazards exist.

Such households may require a temperature

setting less than 120°F to prevent accidental

contact with hot water.

To lower water temperature use point-of-use

temperature limiting devices.

WARNING

Water heater blankets are not recommended

and will void the warranty.

Section II: General Information (cont.) temperature control A solar controller (not provided) shall be used in conjunction with the solar water heater to run all solar components in the heating system. The solar controller will be connected to two thermistors that monitor lower and upper tank temperature. In some cases, only one thermistor (near the bottom of the tank) will be used. The proper temperature setting for domestic hot water use is 120°F/49°C.
PAGE 7
Section II: General Information (cont.) anode rods The anode rod is used as a sacrificial element within the volume of the storage tank. The purpose of the magnesium anode rod is to protect the inside of the tank against corrosion. Anode rods should be inspected twice in the first year and at least yearly once a time interval for inspection has been developed. Water conditions can influence the consumption rate of the anode rods.
PAGE 8
Section III: Pre-Installation location CAUTION This water heater must be located in an area where leakage of the tank, water line connections, or the temperature and pressure relief valve will not result in damage to the area adjacent to the water heater or to lower floors of the structure. When such location cannot be avoided, a suitable drain pan must be installed under the water heater. The drain pan depth must be suitable for draining and collecting water.
PAGE 9
Section IV: Installation water connections CAUTION This water heater incorporates fittings that contain a nonmetallic lining. DO NOT apply heat to these fittings when making sweat connections to the heater. Sweat tubing to an adapter before securing adapter to any fittings on water heaters. ALL PIPING SHOULD CONFORM TO LOCAL CODES AND ORDINANCES.

Section IV: Installation (cont.) Figure 5 shows an example of a domestic solar heating system based on an indirect water heater with two coils. The domestic water can be heated by the solar system as well as the boiler.
PAGE 13
Section IV: Installation (cont.) electrical connections DANGER Confirm that all electrical connections are unpowered before installing or servicing electrical components/connections within the water heater. WARNING The water heater must be electrically grounded in accordance with local codes or, in the absence of local codes, with NFPA 70. Failure to properly wire electrical connections may result in serious physical harm. Electrical power may be from more than one source.
PAGE 14
SECTION V: OPERATION INITIAL START-UP Reference the solar collector installation instructions for proper start-up of the solar collector. Be sure that fluid flow in the solar system is established. HEATING OPERATIONS Condition 1: The minimum temperature difference (for heat transfer) between the potable water at the bottom of the tank and the solar collector is sensed by the solar controller. In addition, the tank temperature is below the maximum tank temperature setpoint (on solar control).
PAGE 15
SECTION V: OPERATION (cont.) CAUTION Hot water in excess of 120°F can cause scalding! The temperature at which injury occurs varies with the person’s age and the time of exposure. The slower response time of disabled persons increases the hazards to them. NEVER allow small children to use a hot water tap. NEVER leave a child or disabled person unattended in a bathtub or shower. Replace the foam dam insert and access cover after adjusting/inspecting the thermostat.
PAGE 16
Section VI: Maintenance (cont.) Flush the tank The solar indirect water heater is glass lined. Elements in the water such as lime, iron and other minerals may accumulate in the heater. It is recommended that the tank be drained and flushed thoroughly once a year to prevent buildup in the tank. SOLAR CONTROLLER AND COLLECTOR PANELS The solar controller and collector panel manufacturer may have a recommended maintenance procedure. Refer to the instruction manual that was received with the solar equipment.
