4.13 HOT WATER HEATER AUTOMATIC DRAINAGE
- The water heater has an automatic drainage function. When the water inlet pressure of the water
heater exceeds 1.0MPa~1.2MPa, the water heater will automatically drain and relieve pressure.
- Do not place objects around the water heater to avoid damage caused by water immersion
when draining. The pressure relief valve is disassembled as shown below.
4.14.CHECK THE WATER HEATER
After the installation of the water heater is completed, it is necessary to check that the water
heater has no air leakage and water leakage, and the ignition operation is normal, and there is no
fault alarm.
- The water heater can be installed with up to three remote controllers. Each remote controller
has two functions which can adjust the set temperature and indicate the error code.
- PRIORITY function: The controller that is activated rst (i.e. button is pressed) is given PRIORITY
function, and can freely adjust the temperature. Remaining controllers will display the set tempera-
ture however will not be able to make any adjustments. After a 15 minute period of inactivity the
priority on the rst remote will cease and priority can then be assigned to another remote by
activating it (i.e. a button is pressed). Then the new controller has priority and the cycle repeats.
- Default setting temperature: At the initial power on, the setting temperature will be the same as
the value set on DIP switch. After the initial use, it will remember the former setting temperature.
- All water heater models have self diagnostic function for safety and convenience when
troubleshooting. If there is a problem with the installation or the unit, it will display a numerical
error codeon the remote controller (or the LED of the computer board will be blink.)
