Flow Rate And Water Temperature; Turning Unit Off; Preventing Freeze Up - Toyotomi Oil Miser OM-148 Operation And Maintenance Instructions

¡Seasonal change of water temperature from the main water source results in different hot
NOTE:
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

SEASON
SUMMER
SPRING & FALL
WINTER
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.
1. Press "POWER SWITCH" to ''OFF'' position. All lamps will go out.
2. Close the fuel tank valve.
In order to prevent any kind of damage or leaks caused by freezing, keep the pipes heated at all times, as
specified below.
CAUTION: In order to prevent the water heater from being broken or develop a leak, regardless of being
used in a cold region or in a warm or hot region, the water supply piping, hot water supply pip-
ing, drain pipe, check valve, valves, expansion tank, and temperature & pressure relief valve are
to be protected with sufficient insulation materials (by wrapping with heat insulation or by
equipping an freeze prevention heater).
1. 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.
Set the Thermostat to the ''VERY HOT'' position, and press "POWER SWITCH" to ''ON'' position.
NOTE: Since this method cannot prevent the water inside of the piping from being frozen, sufficient insula-
tion measures are to be given according to the requirements mentioned in the above cautions.
