IMMERSION THERMOSTAT(S)

FIG. 17 Immersion Thermostat with Adjustment Knob

This water heater uses an immersion thermostat(s) to activate magnetic contactors allowing current to flow to the immersion heating elements. The standard control system uses one immersion thermostat for each 54kW of electric heating power in a water heater. As an option, additional immersion thermostats may be provided to add additional steps of thermostatic control. The sensing bulb for each immersion thermostat is immersed in the stored water in the tank to provide quick, accurate response to changes in water temperature, The thermostat sensing bulb is located in the tank just above the elements it is controlling. The immersion thermostat set point is adjustable by rotating a knob on the control. Turning the knob counter clockwise decreases the temperature set point and turning the knob clockwise increases the set point. The temperature setting shown at the top of the knob is the selected set point. The immersion thermostat has a fixed 6°F (3.3°C) differential.

TEMPERATURE REGULATION

WARNING:

HAZARD OF ELECTRICAL SHOCK – Before opening the electrical access panel to adjust the thermostat make sure the electrical supply to the water heater is turned “OFF”.

DANGER:

Full power is present whenever the cabinet door is opened, even with the pilot

switch(es) turned off.

Set temperature control to the lowest setting which satisfies the hot water requirements of the system. Lower water temperatures help minimize scale formation on the heating elements. See thermostat information below. For sequencer specifications, consult controller literature.

WATER TEMPERATURE SETTINGS

This water heater has an adjustable thermostat to control water temperature. The thermostat is factory pre-set at approximately 125˚ F (51.7° C) or less. Households with small children or invalids may require a 120˚ F (48.9° C) or lower temperature setting to reduce risk of scald injury. Some states may require a lower temperature setting. Check with your local codes or electric utility for local requirements governing the temperature setting. Remember, no water heating system will provide exact temperatures at all times. Allow a few days of operation at the setting to determine the correct temperature setting consistent with your needs.

NOTE:

(1)This water heater, when set at the lower temperature setting, is not capable of producing hot water of sufficient temperature for sanitizing purposes.

(2)Higher stored water temperature increases the ability of the heater to supply desired quantities of hot water, however remember:

 

CAUTION:

Hotter water increases the

risk of scald injury. Setting the temperature selector dial higher provides hotter water, which increases the risk of scald injury.
