from high pressure.
Perform the following commissioning steps only after all the preceding check
items are passed:
(1)
Water replenishment:
Follow the instructions in section
16.1 or the
installation notes on the water tank to replenish water for the tank water tank, and
check whether the pipes or joints for leaks. For initial installation, this step must be
performed by installation and commissioning personnel. If a drain operation is
performed before use of the unit, replenish water before starting the unit.
(2)
Power-on of the unit:
After the unit is powered on, "beep" can be heard
from the wired controller buzzer.
Observe whether the wired controller is displayed
properly. If there is no fault code, the unit is normal.
The wired controller has a power
memory function. However, if the wired controller is power on for the first time, it may
indicate power-on, power-off, or standby.
Note that the unit can be powered on
only after the water tank full filled with water, and do not power on the unit
before the water replenishment.
(3)
Wired controller parameter settings:
provide settings such as
enabling the water return function and correcting the system time
.
(4)
System operating:
After the water tank is full filled with water, check
the waterway system to ensure that the tap or sprayer is closed and cut-off valves of
the inlet and outlet pipes of the water tank are open before starting the unit. When
the heating icon is displayed on the wired controller, check whether the unit runs
properly.
The unit runs properly if the following criteria are met: The fan runs properly;
the unit runs smoothly without shaking or abnormal sound. Hand over the unit to the
user after the unit runs properly at least for 20 minutes.
