TRIAL RUNNING & CAPABILITY
•
•
•
In the Economy Mode and Hybrid Mode, if the
evaporation frosts in a cold circumstance, the system
will defrost automatically to keep effective performance
(3~10min.).
•
During defrosting, fan motor will run at high speed
and e-heater will be started.
•
The temperature on the display is the water
temperature in upper part of water tank (over 1/4)
which you will use, but not that of all the water.
•
The 6 indicators beside the water temperature on
the display are the lower part water temperature.
When the temperature is higher than 40°C, the blue
indicator will light up; if temperature is higher than
50°C, the blue and yellow indicators light up; if
temperature is higher than 60°C, the blue, yellow
and red indicators light up; in the end, when all
indicators light up, the water temperature has reached
the set point.
•
In water using, the temperature of the lower part
may decrease while the upper part still keeps a
high temperature. The system will start heating
the lower part: this is normal.
•
When serious error happens, the system will be unable
to carry on.
Please contact the Authorized Technical Service.
•
When error happens, the buzzer will buzz 3 minutes
every minute, ALARM indicator flashes and the display
indicates the error code and water temperature
alternatively.
Press CANCEL button for 3 seconds to stop the alarm.
When the system is restarted after a long time (trial
running included), it is normal if the outlet water is
unclean.
Keep the tap on and it will be clean soon.
•
When common error happens, the system enters
Standby Mode and could still work, but not so efficient
as normal.
Please contact the Authorized Technical Service.

The system’s operation temp. is within -30°C~43°C
and below are the operation temperature for each
mode.
Economy Mode: 5°C~43°C
•
Hybrid Mode: -30°C~43°C
•
E-Heater Mode: -30°C~43°C
•
Economy Mode: 5°C~43°C, a continuous hot water
demand below 150L(65°C);
•
Hybrid Mode: -30°C~43°C, a continuous hot water
demand between 150L~200L(70°C);
•
E-heater Mode: -30°C~43°C, a continuous hot water
demand between 150L~200L(70°C);
•
In case of intervention of self-protection, the system
stops and self-check starts. The system restarts when
malfunction is solved.
•
In the following circumstances, self-protection starts:
1) Air inlet or outlet is obstacled;
2) The evaporation is covered with too much dust;
3) Incorrect power supply (exceeding the range of
207~253V).
•
In case of intervention of self-protection, the buzzer
will buzz every minute, ALARM indicator flashes
and display shows error code and water temperature
alternatively.
Press CANCEL button for 3 seconds to stop the alarm.
When malfunction is solved, error code is no more
displayed.
Different mode is designed to meet different demand
