SECTION I - GENERAL DESCRIPTION AND CONSTRUCTION

GENERAL DESCRIPTION

This manual describes a packaged electric water heater system designed to meet the requirements of ANSI Z358.1-1998 for tepid water delivery to an emergency drench system. The complete assembly consists of the storage tank, immersion electric heating element(s), thermostat(s), safety relief valve, safety high temperature cut out, mixing valve, 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

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).

TANK CONNECTIONS

The heater is supplied with separate cold water and tepid water connections. A 1-½ inch FNPT connection is supplied for the cold water inlet. The cold water is deflected by means of a baffle within the tank. A 1-¼ inch FNPT union connection is supplied at the mixing valve for tepid water. 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 utilized from the relief valve outlet to a floor drain. A ¾ inch GHT connection is supplied for draining. See drawing for locations.

HEATING ELEMENT

The water heater is supplied with an electric immersion heating element assembly(s), composed of a copper sheathed element(s) 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.

CONTROL THERMOSTAT

The water heater is supplied with an immersion thermostat factory preset at 170°. The immersion thermostat can be adjusted through a range of 100° - 180° F and is adjustable with a flat tip screwdriver.
