General Information cont.-
This unit has no power button. The power can only be shut off at the circuit breaker or disconnect
switch.
After a long shutdown period, the water he
ater’s operation and controls should be checked by qualified
service personnel. Make certain the water heater is completely filled again before placing it in operation.
Temperature Adjustment
CAUTION
Increasing the thermostat setting above the preset temperature may cause severe burns and consume
excessive energy. Hotter water increases the risk of scald injury.
This water heater can deliver scalding temperature water at any faucet in
the system. Be careful whenever using hot water to avoid scalding injury.
Certain appliances, such as dishwashers and automatic clothes
washers, may require increased temperature water. By setting the
thermostat on this water heater to obtain increased temperature water
required by these appliances, you may create the potential for scald
injury. To protect against injury, you should install an ASSE approved
mixing valve in the water system. This valve will reduce the point of
discharge temperature by mixing cold and hot water in branch supply
lines. Such valves are available from the manufacturer of this water
heater or a local plumbing supplier. Please consult with a plumbing
professional.
Safety, energy conservation, and hot water capacity are factors to be
considered when selecting the water temperature setting of the water
heater. Water temperatures above 125°F can cause severe burns or
death from scalding. Be sure to read and follow the warnings outlined
on the label pictured below. This label is also located on the water
heater near the top of the tank.
The thermostat has been set at the factory to 120°F (49°C) to
reduce the risk of scald injury. This is the recommended starting
temperature setting, but it can be adjusted to any temperature
between 100°F and 140°F (38°C and 60°C).
To adjust the temperature, follow these steps:
1. Press the UP or DOWN arrow on the control
panel keypad to the desired temperature.
2. Press ENTER to accept the new setting.
Note:
To change between °F and °C, press and hold MODE.
WARNING
Hydrogen gas can be produced in a hot water system served by this water heater when there has been no
usage for a long period of time (generally two weeks or more).
HYDROGEN GAS IS EXTREMELY
FLAMMABLE.
To reduce the risk of injury under these conditions, it is recommended that the hot water
faucet be opened for several minutes at the kitchen sink before using any electrical appliance connected to
the hot water system. If hydrogen is present, there will probably be an unusual sound, such as air escaping
through the pipe, as the water begins to flow. There should be
NO
smoking or open flame near the faucet at
the time it is open.
