Page 9: General Information
SECTION III GENERAL INFORMATION FEATURES This water heater contains the following features: – HEAT EXCHANGER The heat exchanger (coil) is made of porcelain coated carbon steel tubing and female fittings. If a confirmed leak occurs, contact the plumbing professional who installed the water heater or the manufacturer listed on the rating plate, for additional guidance. - Page 10 General Information continued- THERMOSTATICALLY ACTIVATED MIXING VALVE – An ASSE approved thermostatic mixing valve is supplied with the water heater. The solar heating system may transfer heat into the water heater above the temperature limits set by the thermostats. This may create the potential for scald injury. To protect against injury, you must install the supplied ASSE approved thermostatic mixing valve (a device to limit the temperature of water to protect against scald injury via mixing hot and cold water supply) or equivalent in the water system.

SECTION V WATER CONNECTIONS INSTALL TEMPERATURE AND PRESSURE RELIEF VALVE (if not factory installed) WARNING FAILURE TO INSTALL AND MAINTAIN A NEW, LISTED TEMPERATURE AND PRESSURE RELIEF VALVE WILL RELEASE THE MANUFACTURER FROM ANY CLAIM WHICH MIGHT RESULT FROM EXCESSIVE TEMPERATURE AND PRESSURES. Hydrogen gas can be produced in an operating water heater that has not had water drawn from the tank for a long period of time. - Page 14 Water Connections continued- INSTRUCTIONS FOR SOLAR CONNECTIONS The solar water heater connection labeled “TO SOLAR COLLECTOR” should be piped to the solar return piping. The use of a union and a shut-off valve is recommended. Pipe and fittings between the solar system and the water heater should be ¾”...
- Page 15 Water Connections continued- 2. For a drainback solar heating system, refer to Figure 4. The solar water heater connection labeled “FROM SOLAR COLLECTOR” should be piped to the solar collector supply piping. Mount the pump making sure the flow arrow points toward the water heater. The use of shut-off valves and unions are recommended for future service convenience.
- Page 16 Water Connections continued- TWO-TANK SYSTEM INSTALLATION THE TYPICAL TWO-TANK SYSTEM A typical two-tank system is provided in Figure 5. This system holds two separate volumes of water. The cold water supply is delivered to the solar water heater. If solar energy is available, the water in the solar heater is heated. This heated water is delivered into the backup water heater.
- Page 17 Water Connections continued- Figure 6 – Replacing the Solar Water Heater in a Two-tank Installation To replace the previous solar water heater with the new solar water heater with electric backup, remove the previous solar water heater. The external heat exchanger and pump can also be removed. The new solar water heater with electric backup has an internal heat exchanger allowing direct heat transfer to the water.
- Page 18 Water Connections continued- Figure 7 – Replacing the Backup Water Heater in a Two-tank Installation To replace the previous backup water heater with the new solar water heater with electric backup, remove the backup water heater. The new solar water heater with electric backup has an internal heat exchanger allowing direct heat transfer to the water.
- Page 19 Water Connections continued- Figure 8 – Piping in a Boiler Application (Winter/Summer) The solar water heater with dual heating element also has the capability to function as an indirect water heater with electric backup as shown in Figure 8. In this application, the boiler water heats the potable water.

SECTION VI ELECTRICAL CONNECTIONS Install electric wiring in accordance with the National Electric, ANSI/NFPA 70, and /or the CSA C22.1 Electric Code, latest editions. DANGER Positively assure all electrical connections are unpowered before attempting installation or service of electrical components or connections of the water heater or building. Lock out all electrical boxes with padlock once power is turned off. - Page 21 Electrical Connections continued- NOTICE A solar control and thermistors are not supplied with this water heater. The Tekmar 156, when installed according to manufacturer’s instructions, is an acceptable controller. Other solar controller manufacturers such as Steca and Resol provide controllers appropriate for use with this water heater. Thermistors are not included with the water heater.

Page 22: Operating Instructions
SECTION VII OPERATING INSTRUCTIONS SYSTEM START-UP Follow the solar collector installation instructions to place the collector in operation. Ensure that solar fluid flow operation is established for the installed system. SEQUENCE OF HEATING OPERATIONS -SOLAR AND ELECTRIC BACKUP 1. The solar controller senses a large enough temperature difference between the lower tank and the solar collector to transfer heat into the tank. - Page 23 Operating Instructions continued- CAUTION Before adjusting the thermostat, turn off all power supplied to the solar water heater. The minimum potable water temperature can be changed by adjusting the thermostat. Before any work is done on the water heater, disconnect all power to the water heater and heat source (solar collector) by opening the switch(s) at the main electrical circuit breaker or fuse box.
- Page 24 SECTION VIII MAINTENANCE This solar water heater is intended to provide a service life of many years. Components that require service, however, may be subject to failure. Failure to use the correct procedures or parts in these circumstances may make the water heater unsafe.
- Page 25 Maintenance continued- Sediment (Annual, but harsh water quality may dictate more frequent service) - Depending on water conditions, a varying amount of sediment may collect in the tank. Levels requiring service are indicated by a small temperature difference in the supply and return lines (See also “Scale” below). Repeated flushing usually clears such material.
