General Information cont.-
Vacation Mode
This feature is recommended when you will be away from the home for an extended period of time and hot water is
not needed. In this mode, the unit will reduce the water temperature setting to 50°F (10°C) and will use the most
efficient heating mode to conserve energy while the heater is sitting idle. The unit will automatically resume heating
one day before your return, so that hot water will be available.
To set Vacation Mode:
1. Select Vacation by pressing the MODE button.
2. Input the total number of days you will be gone by pressing the UP arrow. The default is 7 days, maximum
199, or the water heater will remain in Vacation Mode indefinitely by selecting "---".
3. Press ENTER.
For example, if you will be gone 14 days, set Vacation Mode for 14 days using the steps above. The temperature
setting will automatically reduce to 50°F (10°C) for 13 days. At the end of the 13
and temperature setting will reset to ensure hot water is available upon your return.
Extended Shutdown Periods
If the water heater is to remain idle for an extended period of time, the power and water to the appliance should be
turned OFF and the water heater drained to conserve energy and prevent a buildup of dangerous hydrogen gas.
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 heater'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.
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.
