NOTE

• Mixing water with glycol will affect the unit performance.
• Please pay attention to the safety instructions attached to the glycol container.

5.5 Electrical connection

NOTE

• Make sure that the power supply falls within the range of 220-240V\~1ph 50Hz/60Hz and is able to provide enough wattage for the unit. The power supply system must comply with the current national safety regulations.
• The electrical connection must be completed by qualified professionals and must comply with local laws and regulations. The company is not responsible for personal or property damage resulting from any incorrect electrical connections.
• Provide dedicated and suitable leakage protection device for the unit, with a minimum distance of 3 mm among the wiring contacts. The unit must be grounded reliably.

- Make sure that the power cord has a large-enough cross section to withstand the maximum current required. Never use a damaged cable.

• Perform electrical connections according to the wiring nameplate (Figure 5-20 or Figure 5-22) of the unit.

- Secure the cable using clamps in the electric control box to ensure the safety of the power supply cable and the connection cable.

- Do not pull, step on or squeeze the cable. Do not use nails or staples to secure the power cord.

- The cable must be passed through the knockout hole at the foundation.

- An AC contact switch (with contact separation of at least 3mm) must be installed on the fixed wiring to disconnect the machine from the electrical mains and the omnipolar switch.

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

Refer to Table 5-2 and Table 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 result in accidents when the unit burns and becomes damaged.

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

The maximum allowable voltage range variation between phases is 2%.

Select the circuit breaker that has a contact separation of no less than 3 mm in all poles to provide full disconnection. MFA is used to select the current circuit breakers and residual current operation breakers:

5.6 Startup guide

Machine commissioning or first start-up must be performed by a professional.

Before startup, make sure that the installation and electrical connections are made in accordance with this Manual, and that no unauthorized personnel is near the machine during operation.

1) Before starting the unit, make sure that:

The device is positioned correctly.

The water system's flow and piping are correct.

The water pipe is clean.

The air can flow normally.

The condensate water can flow normally to the drain outlet and the elbow.

The heat exchanger is clean.

The electrical connection is correct.

The connecting cable is secure.

The power supply meets requirements.

The motor works normally within the allowable value.

6 SERVICE GUIDE

Ask a professional technician to repair a faulty unit.

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.

If there is any damage, such as electric shock or fire, caused by the unit, contact your dealer.

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

Error Countermeasure
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.
When a centralized controller is used, the unit number is displayed on the user interface, 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.

If the error occurred does not fall within those described in the above table, follow the steps below.

Error Countermeasure
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 during unit 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.If any, 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 unit is running in Cool mode.Check whether there is too much heat dissipated from any heat source in the room.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 (if any) will 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).

NO.	Error	Name		Fault Indicator	Bluest Action Error Code
1	Error	E?PROM communication error	Steady on	Flashes once every 3 seconds	Buzzes twice every 3 seconds
2	Error	Room temperature sensor port exception	Steady on	Flashes twice every 3 seconds	Buzzes twice every 3 seconds
3	Error	Coil sensor (T2C) port exception	Steady on	Flashes 3 times every 3 seconds	Buzzes twice every 3 seconds
4	Error	Coil sensor (T2C) port exception	Steady on	Flashes 3 times every 3 seconds	Buzzes twice every 3 seconds
5	Error	DC motor stall fault	Steady on	Flashes 4 times every 3 seconds	Buzzes twice every 3 seconds
6	Protection	Water level exceeding warning line	Blinking	Flashes once every 3 seconds	Buzzes twice every 3 seconds
7	Protection	Model protection not set (DIP switch of the unit not listed in the model table)	Blinking	Flashes twice every 3 seconds	Buzzes twice every 3 seconds
8	Protection	Water temperature protection	Blinking	Flashes 3 times every 3 seconds	Buzzes twice every 3 seconds
9	Protection	Anti-freezing protection	Blinking	Flashes 4 times every 3 seconds	Buzzes twice every 3 seconds
10	Protection		Blinking Remote shutdown	Flashes 5 times every 3 seconds	Buzzes twice every 3 seconds

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 Cool mode, when the pipe water temperature exceeds the allowable range of room temperature, the fan speed will be maintained at a low level to avoid direct exposure to hot air. In Heat 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 that indicated on the user interface. Swing is a customized function. When Swing is enabled but the fan direction does not change accordingly, it is because the unit is responding to other control instructions.

3) Fault symptom: white fog from a certain unit

This may result from high humidity during cooling operation. If the fan coil interior is dirty, 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

The unit will absorb odours of rooms, furniture, cigarettes, etc., and then disperse the odours. Odours might occur after small animals enter the unit.
