Lochinvar Commercial Electric Water Heaters warranty Temperature Adjustment

WARNING:

SHOULD OVERHEATING OCCUR OR THE TEMPERATURE CONTROLS FAIL TO SHUT OFF, TURN OFF OR DISCONNECT THE ELECTRICAL SUPPLY AT THE MAIN POWER DISCONNECT, EXTERNAL TO THE APPLIANCE.

DANGER

•Water temperature over 125°F (51.7°C) can cause severe burns instantly or death from scald.

•Children, disabled and elderly are at highest risk of being scalded.

•See instruction manual before setting temperature at heating appliance.

•Feel water before bathing or showering.

•If this appliance is used to produce water that could scald if too hot, such as domestic hot water use, adjust the outlet control (limit) or use temperature limiting valves to obtain a maximum water temperature of 125˚F (51.7˚C).

Always close the electrical control panel door after making a temperature adjustment. Turn on electricity.

TEMPERATURE ADJUSTMENT

1.Turn "OFF" the electrical power to the water heater. If the power disconnect point is out of sight, lock it in the open ("OFF") position and tag to prevent unexpected application of power.

2.Open the water heater's electrical access panel.

3.Adjust each immersion thermostat to the desired temperature setting by turning the adjusting knob. Each thermostat will be factory pre-set to approximately 125°F (51.7°C) or less as shipped.

4.Close the water heater's electrical access panel.

5.Turn "ON" the electrical power to the water heater.

CAUTION

The maximum temperature setpoint that should be set for the Surface or Immersion Thermostats is 190°F (88°C).

HIGH WATER TEMPERATURE

LIMIT CONTROL

FIG. 13 High Water Temperature Limit Control - Fixed Setting

The unit is equipped with a fixed setting, manual-reset high water temperature limit control(s). The water heater temperature limit control has a fixed limit setting of 195°F (90.6°C). If water temperature exceeds the limit set point, the limit will break the control circuit and shut down the unit. The limit control can only be reset after the water temperature has cooled below the set point of the limit. The high water temperature limit control for the standard surface thermostat controls is the contained in the upper portion of the surface thermostat and mounted above each heating element. The high water temperature limit control for the immersion thermostat and contactor option is mounted on the surface of the tank, above the heating element installed at the highest point in the tank. The limit control is covered with an insulation blanket which must be removed to push the red reset button.

CAUTION

Disconnect the main power to the heater before opening the element access panel to reset the high limit control.

NOTE:

The high limit control will not reset until the water temperature has dropped below the set point of the high limit.
