SECTION I - GENERAL DESCRIPTION AND CONSTRUCTION

GENERAL DESCRIPTION

This book describes a packaged electric water heater that is a stationary, self-contained unit. The complete assembly consists of the storage tank, immersion electric heating element(s), thermostat, safety relief valve, safety high temperature cut out, magnetic contactor(s), and any other required electrical operating control. Optional equipment may be supplied with your unit. Please consult the product drawing for details specific to your assembly. The unit is factory assembled, insulated, jacketed, wired, tested, and ready for electrical and plumbing service connections.

CONSTRUCTION

TANK

Standard Tank Construction:

The standard storage tank is constructed of steel and internally lined with specially formulated Hydrastone cement to a ½-inch minimum thickness. The tank is designed for a maximum allowable working pressure of 150 psi (300 psi TP).

Optional Tank Construction:

Optionally, the storage tank may be constructed of all welded solid copper-silicon alloy (ASTM B-96) or type 316L stainless steel for maximum tank longevity. For these options, no internal lining is required due to the non-ferrous materials used in the construction of the pressure vessel. The tank is designed for a maximum allowable working pressure of 150 psi (300psi TP).

TANK CONNECTIONS

The heater is supplied with separate cold water and hot water connections. Water entering the cold water inlet is deflected by means of a baffle within the tank. The hot water outlet includes a built in heat trap to prevent hot water from radiating out from the heater. A ¾-inch FNPT connection is located on the side of the heater for mounting a combination safety temperature and pressure relief valve. An overflow line should be installed from the relief valve outlet to a floor drain. A ¾-inch GHT connection is supplied for draining. See drawing for locations and sizes.

HEATING ELEMENT

The water heater is supplied with an electric immersion heating element assembly(s), composed of incoloy sheathed elements that are brazed into a brass flange. Each assembly is fastened to a corresponding tank flange using a gasket and four (4) 3/8-16 x 1-inch long hex head steel bolts and nuts. See drawing for voltage and power ratings.
