5 SECTION I - GENERAL DESCRIPTION AND CONST RUCTION 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 hig h temperature cut out, and any other required e[...]

6 TEMPERATURE HIGH LIMIT SWIT CH As a safety device, a surface mounted hig h temperature cut-off switch with manual reset, factory set at 190° F is provided. I n the event of an over-temperature condition, the thermostat will disengage the power from the unit, (in the HSE model the thermostat will disenga ge the operating coils in the magne tic co[...]

7 MAGNETIC CONTACTOR (HSE Models Only ) The magnetic contactor(s) is a heavy-duty resistiv e load ty pe rate d for 100,000 cy cle s. The contactor s upplies power to th e hea ti ng e lem en t( s) b as ed on t he resistive load (non-inductive) of the hea ter only when the thermostatic switc h is engaged, the reby pulling in the contacts until the de[...]

8 SECTION II – INSTALLATION WARNING / CAUTION DO NOT TURN ON THE ELECTRI C POWER SUPPL Y to this equipment until heate r is completely filled with water and all air has been re leased. If the heater is NOT fille d with water when the power is turned on, the heating elements will burn out. For protection against excessive pressures and temperature[...]

9 PIP ING INSTALLATION NOTE: The most effect ive means for preventing deteriorat ion from accelerated corrosi on due to galva nic and stray curr ent is the installation of dielectric fittings/unions. The installation of the se fittings is the responsibility of the installing contractor. 1. Thread cold water inlet and diffuser assembly into tank. Di[...]
