7. Installation Inspection & Startup

Installation Inspection

After installation, the installers shall re-inspect and confirm the following items have been made.

Note:

To avoid human injury, before starting up the unit, the power supply shall be disconnected.

1. The unit has been firmly connected with the hanging rods and slabs;

2. Air pipes have been completely connected and firmly installed;

3. Water pipe connection has been completed without leakage;

4. Drain pipe connection has been completed without leakage;

5. Electric control wires have been completely connected without poor contact and missing;

6. This manual has been carefully read through. Operators are generally familiar with the unit and can operate it.

Startup

The fan coil unit can be controlled with the motor speed switch or the controller. The controller consists of a motor speed switch, an ON/OFF switch and a thermostat. The thermostat controls on/off of the chilled water valve and is normally provided with a temperature setting dial. The speed switch is marked with OFF / HIGH / MID / LOW. It controls the motor speed and thus the air flow.

Air Discharge

For first water filling, the fan coil pipeline may retain some air, which will be finally concentrate on top of the coil. A manual discharge valve is provided at the water outlet joint of the coil. When abnormal noise is heard due to residual air in the coil, turn the discharge valve knob to release the air. If the knob is too tight, you may use a pair of pinchers to turn it anticlockwise until water flows out of the valve steadily, and then tighten the knob again.

9.Brief Introduction of Electric controll functions

9.1 Control system features

Can be controlled with outdoor unit simultaneously (The relative outdoor unit must have this function too)

9.2 Signal LED functions：

LED of infrared remote control type includes: RUN, TIMER, COMP, PUMP. RUN LED also can be used as Failure LED.When the system startup, RUN LED is on, and if the system stops running ,RUN LED will be off .If the TIMER or SLEEP function has been set, TIMER LED will be on , or it will be off. When the compressor starts to run after being electrified, COMP LED will be on , or it will be off.When the water pump starts to run after being electrified, PUMP LED will be on , or it will be off .If the system failure occurs,the LED will flash regularly, please refer to the Trouble diagnose according to the flash times.

9.3 Control features

(1) AUTO Function：

In AUTO mode , system can feel the temperature automatically，and change the running mode

automatically according to the user’s comfort .then adjust the room temperature,the user can always

stay in a comfortable environment.

(2) Auto Restart Function

If the power supply cut off suddenly or the other reasons cause the system stop, the unit will

automaticlly recover the previous running mode once the power supply is on.

To set the AUTO restart function:press the SLEEP button 10 times within 5 seconds continuously,

system enters AUTO Restart state.To cancel this function : when the unit in this mode ,press the

SLEEP cutton 10 times within 5 seconds continuously,then the auto restart function is cancelled.

(3) TIMER Function

System running time can be set by the detector and the timer, this intelligentized function would

make the user more comfortable .

(4) AUTO check function

Unit can check the failure automatically, and show the failure by failure code or flashing LED, easy

to analyze and resolve the problem.

（5）Anti-cold air in heating mode

In heating mode, according to the coil temperature ,unit can estimate the temperature of outlet air

flow automatically to avoid the cold air blowing out , the user would feel more comfortable.

9.4 System protection

Communication failure

Indoor PCB will not be controlled by the operation panel compulsorily, and the PCB will not alarm

because of the communication failure with the operation panel.

When the operation panel can not communicate with the indoor PCB normally, the operation panel

will alarm.

Indoor PCB can be controlled by remote controller or wired controller; also it has hold-on function.
