Page 3: General Information
GENERAL INFORMATION This electric water heater’s design is certified by Underwriters Laboratories (UL) and listed in accordance with UL 1453. C-UL listed in accordance with Canadian National Standard C22.2, No. 110-M90. This water heater must be installed in accordance with local codes. In the absence of local codes, install this water heater in accordance with the latest edition of the National Electrical Code. -
Page 4: Installation
General Information continued- A sacrificial anode(s) is used to extend tank life. Removal of any anode, for any reason, will nullify the warranty. In areas where water is unusually active, an odor may occur at the hot water faucet due to a reaction between the sacrificial anode and impurities in the water. - Page 5 Locating The Water Heater continued- Water heater corrosion and component failure can be caused by the heating and breakdown of airborne chemical vapors. Examples of some typical compounds that are potentially corrosive are: spray can propellants, cleaning solvents, refrigerator and air conditioning refrigerants, swimming pool chemicals, calcium or sodium chloride, waxes and process chemicals.

Page 6: Water Connections
Water Connections Note: Before proceeding with the installation, close the main water supply valve. After shutting the main water supply valve, open a faucet to relieve the water line pressure in order to prevent water from leaking out of the pipes while making the water connections to the water heater. - Page 7 Water Connections continued- WARNING For protection against excessive temperatures and pressure, install temperature and pressure protective equipment required by local codes, but not less than a combination temperature and pressure relief valve certified by a nationally recognized testing laboratory that maintains periodic inspection of production of listed equipment or materials, as meeting the Requirements for Relief Valves and Automatic Gas Shutoff Devices for Hot Water Supply Systems, ANSI Z21.22, and the Standard...
- Page 8 Water Connections continued- WARNING Hydrogen gas can be produced in the hot water system served by this water heater when there has been no usage for a long period of time (generally two weeks or more). Hydrogen gas is extremely flammable.
- Page 9 Water Connections continued- Figure 1 Water temperature over 125°F can cause severe burns instantly or death from scalds. Children, disabled and elderly are at highest risk of being scalded. Review this instruction manual before setting temperature at water heater. Feel water before bathing or showering.

Page 13: Electrical Connections
Electrical Connections Before any electrical connections are attempted, be sure the water heater is full of water and that the manual shut-off valve in the cold water supply line is open. Heating elements, which have been energized for a very short period of time, can be damaged (burned-out) if they are not completely immersed in water. -

Page 15: General Operation
GENERAL OPERATION Before closing the switch to allow electric current to flow to the water heater, make certain that the water heater is full of water and that the cold water inlet valve is open. Complete failure of the heating elements will result if they are not totally immersed in water at all times. -
Page 16: Maintenance
Thermostat adjustment continued- DANGER Hotter water increases the risk of scald injury. Scalding may occur within five (5) seconds at a temperature setting of 140°F (60°C). To protect against hot water injury, install an anti-scald tempering valve in the water system. - Page 17 Maintenance continued- The following maintenance should be performed by a qualified service technician at the minimum periodic intervals suggested below. In some installations, the maintenance interval may be more frequent depending on the amount of use and the operating conditions of the water heater. Regular inspection and maintenance of the water heater will help to insure safe and reliable operation.
- Page 18 Maintenance continued- 7. If this water heater is equipped with fuses, before removing any fuse, disconnect the all power to the water heater. Open the control box door and replace fuses according to the size indicated on the wiring diagram affixed to the inside of the control box door.

SERVICING GUIDE This “Servicing Guide“ section of this Installation and Operation Installation manual is provided for the purpose of improving the effectiveness and the efficiency of servicing this water heater. This information is intended to assist qualified service personnel. Servicing of this water heater may require knowledge of electrical testing instruments. - Page 20 Servicing Guide continued- Certain other control components are available as “Optional“. When these optional components are installed with the water heater, the control circuit wiring diagram accordingly will include these components. The optional equipment available from the manufacturer includes the following: ...
- Page 21 Servicing Guide continued- The following unusual situations will give reason for the pressure controls to interrupt the electrical current to the coil of the contactor: Upon installation or occasions of re-starting heater operation, if the inlet supply line is closed (i.e. a shut-off valve), the high pressure limit may be exceeded due to reasons of thermal expansion of the water.
- Page 22 Servicing Guide continued- When installing the control refer to the direction of the arrow on the hex and insure that it is pointing upwards. If it is not pointing upward, the control switch will not activate when the tank is refilled with water. Refer to Figure 7 for clarification.
- Page 23 Servicing Guide continued- The following unusual situations will give reason for the alarm to sound: If a High Pressure Control is installed, upon installation of the water heater or occasions of re-starting water heater operation, if the inlet supply line is closed (i.e. a shut-off valve), the high pressure may be exceeded due to reasons of thermal expansion of the water.
- Page 24 Servicing Guide continued- Electrical Door Lock: An electrical door lock is offered in order to secure the access to the water heater control cabinet. This device will lock the control cabinet door when the 120VAC control circuit voltage is applied to it. Note: Once the door is opened, the water heater can be re-energized, if necessary, for service diagnosis.
