Light Duty Commercial Three Element Electric Water Heaters Use and Care Manual Installation Start-Up Maintenance Parts Warranty Single or Three Phase Simultaneous or Non-Simultaneous Operation This manual must only be used by a qualified installer / service technician. Read all instructions in this manual before installing. Perform steps in the given order. Failure to do so could result in substantial property damage, severe personal injury, or death.
The following defined terms are used throughout this manual to bring attention to the presence of hazards of various risk levels or to important product information. IMPORTANT SAFETY INSTRUCTIONS When using electrical appliances, basic safety precautions to reduce the risk of fire, electric shock, or injury to persons should be followed, including: DANGER indicates an imminently hazardous situation which, if not avoided, will result in serious personal injury or death. 1.
Part 1 - General Safety Information This water heater is approved for indoor installations only and is not intended for use as a pool heater. Clearance to combustible materials: 0” top, bottom, sides, and back. Heater must have room for service: 24” front, 3” back, 6” top, and 6” sides are minimum recommended service clearances. (A combustible door or removable panel is acceptable front clearance.) This water heater has been approved for closet installation and installation on combustible flooring.
Part 2 - Prepare the Water Heater Remove all sides of the shipping crate to allow the heater to be moved into its installation location. COLD WEATHER HANDLING - If the water heater has been stored in a very cold location (BELOW 0oF) before installation, handle with care until the components come to room temperature. Failure to do so could result in damage to the water heater. Incorrect ambient conditions can lead to damage to the heating system and put safe operation at risk.

• maximum contaminant levels (40 CFR Part 143.3). If the water contains contaminants higher than outlined by the EPA, water treatment is recommended and additional, more frequent maintenance may be required. Chloride concentration less than 100 ppm (mg/L) • Do not fill appliance or operate with water containing chlorides in excess of 100 ppm (mg/L). • Using chlorinated fresh water should be acceptable as levels are typically less than 5 ppm (mg/L).
Figure 3 - Installing Cold Inlet and Hot Outlet Fittings CAUTION The Cold Inlet and Hot Outlet Fittings MUST BE INSTALLED according to the steps in Figure 3 for the electric water heater to operate properly. Failure to install these fittings properly will result in improper water heater operation, possible substantial property damage, and increased costs. Service calls to repair the installation and properly install these fittings ARE NOT COVERED by water heater warranty.
Part 3 - Piping A. Plumbing It is mandatory that all plumbing be done in accordance with federal, local, and state plumbing codes and practices. Failure to properly install the water heater WILL VOID the warranty. It is also necessary to use both thread tape and pipe dope on all mechanical plumbing connections. Install unions on the hot and cold water connections to easily disconnect the water heater for servicing.
F. Scalding To avoid water damage or scalding due to relief valve operation: • Discharge line must be connected to relief valve outlet and run to a safe place of disposal. Terminate the discharge line in a manner that will prevent possibility of severe burns or property damage should the relief valve discharge. • Discharge line must be as short as possible and the same size as the valve discharge connection throughout its entire length.
• Allow sufficient time for the heater to completely fill with water. • Verify elements are installed correctly. Check for leaks at the water heater and throughout the system. H. Applications When filling the water heater, open a hot water tap to release air in the tank and piping. The tank must be full of water before the heater is turned on. Failure to ensure the water heater is full before turning it on could result in damage to the water heater and other property damages.
