OPERATING AT HIGH TEMPERATURE
CAUTION:
Risk of scald injury. Before changing temperature setting make sure that the water heater is not
being used by any of your family at any place in the house.
NOTE:
¡
Seasonal change of water temperature from the main water source results in different hot
water temperature supplied. Use hot water supply faucet to control hot water temperature,
or readjust temperature setting.
¡
The hot-cold mixing faucet is recommended to ensure safe and comfortable use of the water
heater. Choose a mixing faucet which can provide a comfortable water temperature with less
temperature fluctuation.
¡
After installing the mixing faucet, set the temperature selector knob at the position of "VERY
HOT" and then gradually adjust the water temperature by adding cold water to your prefer-
able level. Sufficient care must be taken not to misoperate this adjustment, which may result
in scalding your hands.
FLOW RATE AND WATER TEMPERATURE
NOTE:
Whenever high temperature water is required for continuous demand, lessen the flow rate.
Whenever low temperature water is required, the flow rate may be increased.
The flow rates are calculated under the conditions of standard installation and normal usage so
that they will vary according to installation, usage and temperature.
