- The grounding wire in the electrical control box needs to be longer than the current-carrying wire.

- For DC 4-Pipe series, the cooling water valve and heating water valve would open at the same time when the PCB receive the fan speed control signal from 0-10V wired controller. Please don't turn on the chiller and heat pump simultaneously, and we suggest to install another check valve to stop the water flow when it is necessary.

Figure 5-21 Cabling diagram(DC FAN)

Refer to Tables 5-2&5-3 for the specifications of the power cord and communication wire. A wiring capacity that is too small will cause the electrical wiring to become too hot, and lead to accidents when the unit burns and becomes damaged.

Select the wire diameters( minimum value) individually for each unit based on the table 5-3.

Maximum allowable voltage range variation between phases is 2%.

Select circuit breaker that having a contact separation in all poles not less than 3 mm providing full disconnection, where MFA is used to select the current circuit breakers and residual current operation breakers:

The motor works normally within the maximum allowable value.

6 SERVICE GUIDE

Ask a professional technician to repair the unit in case it goes wrong.

Make sure the power supply is disconnected during repair.

6.1 Troubleshooting

The warranty does not cover the damage caused by dismantling or cleaning of the internal components by unauthorized agents.

WARNING

When any unusual situations arises (burning odour, etc.), stop the unit immediately and turn off the power.

As a result of a certain situation, the unit has caused damage, an electric shock or a fire. Please contact the agent.

The system maintenance must be carried out by qualified maintenance personnel.

Error Measures
If a safety device, such as a fuse, circuit breaker or a leakage circuit breaker is triggered frequently or the ON/OFF switch is not working properly.	Turn off the main power switch.
The operating switch is not functioning normally.	Turn off the power supply.
If a centralized controller is used, the unit number is displayed on the user interface, and the operating indicator is flickering, and an error code is shown on the screen as well.	Notify the installation personnel and report the error code.

Except as noted above, if the above faults are not typical and the unit still fails, follow the steps below.

Error Measures
If the system does not run at all.	Check whether there is a power failure. Wait for the power supply to be restored. If a power failure occurs when the unit is still running, the system will restart automatically once the power is restored.
The system is running but there is insufficient cooling or heating.	Check whether the air outlet is blocked by any obstacles.Remove the obstacles.Check whether the filter is blocked.Check the temperature setting.Check the fan speed settings on the user interface.Check whether the doors and windows are open.Close the doors and windows to shut out wind from the external environment.Check whether there are too many people in the room when the cooling mode is in operation.Check whether the heat source of the room is too high.Check whether there is direct sunlight into the room. Use curtains or blinds.Check whether the angle of air flow is appropriate.

1) Error code overview

If a centralized controller is used, error codes appear on the user interface. Contact the installation personnel and inform them of the error code, unit model and serial number (you can find the information on the nameplate of this unit).

Refer to Maintenance Manual for troubleshooting.

6.2 Non-Unit Related Faults

The following fault symptoms are not caused by the unit itself:

1) Fault symptom: Fan speed is not consistent with the setting

The fan doesn't respond to the controller. In cooling mode, when the pipe water temperature is outside the allowable range of room temperature, the fan speed will be maintained at a low level to avoid direct exposure to hot air. In heating mode, when the pipe water temperature reaches a certain low level, the fan speed will also be maintained at a low level to avoid direct exposure to cold air.

2) Fault symptom: Fan direction is not consistent with the setting

The fan direction is inconsistent with the direction indicated on the user interface. Swing is a customized function. If the customer customizes this function and the fan direction does not correspond to the set direction, this is because the unit is controlled

3) Fault symptom: white fog from a certain unit

This may result from high humidity during cooling mode. If the interior pollution of the fan coil unit is severe, the indoor temperature distribution may be uneven. At this time, you need to clean the inside of the unit. Ask the dealer for information on how to clean the unit. This operation must be carried out by qualified maintenance personnel.

4) Fault symptom: dust and dirt in the unit

This may happen after the unit is used again after being left idle for a long period. This is because there is dust inside the unit.

5) Fault symptom: odour from unit

This unit will absorb the odours of rooms, furniture, cigarettes and others, and then disperse the odours again. Odour might occur after small animals enter the unit.
