Air Source Heat Pump Water Heater

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
System clock time setting, disinfection function setting, etc.
(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.
