Operation Instructions

9. Delay Time Setting
Delay function means that, system automatically calculates the time needed to reach
temperature setting value with a defaulted 2150 W power, then determines the time to
start heating, and automatically heats to the set temperature before the preset delayed
time to use hot water. Two Delay Times (Time 1 + Time 2) means machine as needed can
heat water in two delayed use times. This machine can be manually set two delayed water
use times. Setting will take PC clock time as reference. Defaulted Time 1 use time is 17:00
and Time 2 use time is 06:00. In Delay mode, system default heating power 2150 W can't
be adjusted.
Example: as shown in Fig. 12, set delayed use Time 1 at 10:30.

With machine powered on, consecutively press Mode button until it enters Time 1
operation status with delay indication and symbol lighted. Press Set button to enter
Time 1 hour setting status with Time 1 hour digits flashing. Press or button to get
10:00. While hour digits are flashing, you can press Set button to confirm and enter Time 1
minute setting. Adjust the value to 10:30 with or button.

Then you may press Set button to confirm current settings or wait 6 s after which

press Mode button to enter Time 2 operation mode and set Time 2 time with Set button.
Note: If large quantity hot water is used after delay mode is started and water heaters
starts heating, resulting in water heater still hasn't reached temperature setting at delayed
use time, machine will automatically extend heating for half an hour and stops. If actual
temperature has reached setting value before delayed use time, and it decreases by 5
before reaching delayed use time, machine will calculate heating time again and
determines if re-heating is needed or not. Likewise, if water heater hasn't reached set
temperature at delayed use time due to too low supply voltage, machine also
automatically extends for half an hour and stops.

10. Operation Mode Selection

After powering on, by consecutively pressing Mode button, system will shift between
Real-time Heat / Warm (with Real-time indication), Medium Warm (with Medium Warm

Note: Make sure the wall rack is reliably hung on the hooks before releasing your hands.
Otherwise, the water heater may fall and cause human injury or property loss.

Connection and Use of Safety Valve:
The safety valve should be connected to the cold water inlet pipe. Please check
carefully if the direction is correct after installation. The correct direction of installation
is that the arrowhead on the safety valve should be pointed to the water heater.
Please connect the drain hose to the safety valve. Connect one end of the hose to the
safety valve vent and the other end to the sewage drain. The hose can be cut short or
extended as necessary. The hose shall be installed as inclined downward.
The water may drip from the discharge pipe of the pressure relied device and that this
pipe must be installed in a continuously downward direction and in a frost-free
environment. Check safety valve once a month as follow: move the small handle of
safety valve, if there's water flowing out, safety valve is normal; if there's no water flow,
please contact local after-sales service station.
The pressure relief device is to be operated regularly to remove lime deposits and to
verify that it is not blocked.

are free of water leakage, and insert the power plug.

1. Powering On
This product has a power failure memory function, i.e. it remembers temperature setting,
power level, clock and current working status. Upon connecting power, all indications on
the display are displayed for 2 s before the system goes into standby status (with only
clock display and all buttons except On/Off button inactive) or previous working status
before power failure with corresponding indicators lighted on. For example, machine as
shown in Fig. 6 is in standby status with only On/Off button active.
