4 Commissioning and Trial Run
4.1 Precautions for Commissioning
Before commissioning, ensure that the power supply model, possible usage range (pipe distance,
indoor and outdoor high and low voltage difference, and power supply voltage), and installation space
meet user requirements.
After verifying that no exception exists upon commissioning, introduce the operation and
maintenance method to the customer according to the user manual. In addition, deliver the precautions
and user manual to the customer for careful storage.
4.2 Brief Introduction to Commissioning
As engineering design, installation, and system control require high precision, commissioning must
be performed after installation. The unit can be delivered if no exception is detected during
commissioning.
4.3 Engineering Commissioning
4.3.1 Air Exhaust for Initial Run
(1) After the water tank is fully injected with water, exhaust air in the pipe. (In initial installation, this
operation shall be implemented by the installation and commissioning personnel. During
normal operation, users also need to exhaust air in the pipe before water makeup startup after
water in the water tank is discharged. Operations must be in accordance with the manual or
label on the water tank.)
(2) Inject water fully and check leakage. Turn on the water inlet/outlet cut-off valve of the water tank
and the hot water tap or shower head on the user's side. If water flows out continuously at the
tap or shower head, the water tank is full of water. Then turn off the tap or shower head. Check
whether leakage exist in the water pipeline, especially at joints. When no leakage is found,
power on the unit.
(3) Unit power-on: After the unit is powered up, the wired controller buzzes for once. Check
whether an error code is displayed on the wired controller. It is normal if no error code is
displayed. As the wired controller has the memory function for blackout, it may be in the off or
standby mode when it is powered on for the first time. Note: The unit must be powered on by
strictly following the air exhaust steps.
(4) Unit running: After air is exhausted, check the water pipeline system. Ensure that the tap or
shower head on the user's side is turned off and other cut-off valves are turned on before
starting the unit. When the wire controller displays the heating icon, check to make sure the unit
is running normally.
Judgment criteria include that the fan runs properly and the unit runs stably without obvious
shake and noise. After the unit runs properly for at least 30 minutes and no exception is found,
it can be delivered to the user.
Attention:
All operations should be performed in accordance with the corresponding product manual.
