4.4 Installation

1. First select an installation position. According to the size of the communication line of the

wire controller, leave a recess or a embedded wire hole to bury the communication line.

2. If the communication line between the wire controller (85×85×20) and the indoor unit is

surface-mounted, use 1# PVC pipe and make matching recess in the wall (refer to Figure 6);

If concealed installation is adopted, 1# PVC pipe can be used (Refer to Figure 7).

3. No matter if surface mounting or concealed mounting is selected, it is required to drill 2 holes

(in the same level) which distance shall be the same as the distance (60mm) of installation

holes in the bottom plate of the wire controller. Then insert a wood plug into each hole. Fix

the bottom plate of the wire controller to the wall by using the two holes. Plug the

communication line onto the control panel. Lastly install the panel of the wire controller.

Caution:

During the installation of the bottom plate of the wire controller, pay attention to the direction

of the bottom plate. The plate’s side with two notches must be at the lower position, and otherwise

the panel of the wire controller cannot be correctly installed.

2） Vacuum-pumping and leak detection

 Dismantle the bonnet of refrigerant valve and air valve.
 Align with the center of piping and adequately tighten nuts of connecting pipes by hand
 Tighten the nuts with a spanner.
 Remove the one way valve cap of air valve.
 Unscrew the spool of refrigerant valve for 1/4 turn with a socket head wrench, and at the

same time push up the spool of air valve with a screwdriver to let air give off.

 Air exhaust continues for 15 seconds until coolant gas appears, immediately shut off one way

valve and tighten the valve cap.

 Totally open the spool of refrigerant valve and air value (as shown in Figure 3-1-4)

Figure 3-1-4

 Tighten the valve caps and use soapy water or a leak detector to check any leakage on indoor

unit, outdoor unit and connection parts of pipes.

Caution：

If conditions are allowed, a vacuum pump shall be used for drawing off air inside the system at a

valve. Method for creation of vacuum by using a vacuum pump is as follows:

 Take out the nut cover of the inlet for refrigerant.
 Connect the tube of the vacuum watch with the vacuum pump, having the low-pressure end

remains.

 Take out the valve cover of the gas valve together with the liquid valve.
 Loosing the cord of liquid valve until the pressure rise to 0 bar.
 Dismantle the tube from the cover of the inlet for refrigerant then, tighten the cover.
 Loose the valve cord of the gas valve as well as the liquid valve entirely.
 Tighten the valve cover of the gas valve and liquid valve so as to check whether leakage

occurred.

3) Installation of Protective Layer of Connecting Pipe

 To avoid generation of condensate on the connecting pipe and avoid leakage, the big pipe and

the small pipe of the connecting pipe must be covered by thermal insulation materials, be

bundled by adhesive tape, and be isolated from air.

 The joint connecting to the indoor unit must be wrapped by thermal insulation material.

There shall be no gap between the connecting pipe joint and the wall of the indoor unit. Refer

to Figure 3-1-6.

Figure 3-1-6 Figure 3-1-7

U-MATCH AIR CONDITIONERS INSTALLATION

80

 Use adhesive tape to bundle the connecting pipe and the cables together. To prevent

condensate from overflowing out from the drainage pipe, separate the drainage pipe firm the

connecting pipe and the cables.

 Use thermal insulation tape to wrap the pipes from the bottom of the outdoor unit until the

upper end of the pipe where the pipe enters the wall. When wrapping thermal insulation tape,

the later circle of tape must cover half of the front circle of tape (Figure 3-1-7).

 Wrapped pipe must be fixed to wall using pipe clamps.

Caution:

 After the pipes are wrapped by protective materials, never bend the pipes to form very small

angle, and otherwise the pipes may crack or break.

 Do not wrap the protective tape too tight, otherwise the efficiency of thermal insulation may

be decreased. Ensure that the condensate drainage flexible tube is separate from the bundled

pipes.

 After the protective work is completed and the pipes are wrapped, use seal material to block

the hole in the wall, so as to prevent rain and wind from entering the room.

3.2 Caution in Connecting Pipes

Arrangement of connecting pipes shall be performed according to sit conditions with reference to

the following principles.

 Try to shorten the length of connecting pipes, within 5m for the better.
 Try to reduce height difference between indoor unit and outdoor unit.
 Try to reduce number of joint bends of connecting pipes.
 If the length of connecting pipes is more than 20m, adequacy of lubricant of the system must

be checked; and if necessary, add more lubricant properly.

 Filling amount of refrigerant in the system is matched to a 7m connecting pipe. If the

connecting pipe is needed to lengthen, appropriate amount of refrigerant should be added.

How much refrigerant should be added for every meter extension refers to the following table.

Allowable maximum pipe length is 30m.

 If height difference between indoor unit and outdoor unit exceeds 10m in installation of air

conditioner, an oil return bend must be mounted at an interval of 6m.

 If heights of indoor unit and outdoor unit are different, pipes should be laid out with reference

to Figure 3-2-1.

If water full protection continues for 2 hours and fails to restore,

it is believed that the water pump is at fault and all loads are shut

off and fail to restore automatically.

E1

Compressor High

Pressure Protection

High voltage switch

When high voltage protection is detected for continuous 3

seconds, all loads are shut off (except for the four way valve), all

buttons and remote control signals except for power-on or

power-off are shielded and fail to restore automatically, the unit

should be powered off and on, or failure should be removed after

power supply is restored.

E2

Indoor Frost-Proof

Protection

Evaporator of indoor

unit

Thermal bulb

When the unit has been running for refrigeration or

dehumidification for a period of time and evaporator thermal

bulb is detected to be lower than -2

℃, the unit will report a fault

and stops the compressor and the outdoor unit. The unit will

begin to operate after temperature is

≥10℃ and the compressor

keeps outage for 3 minutes.

E3

Compressor Low

Pressure Protection

Low voltage switch

When the unit is started or at standby (detection will begin 3

minutes after the compressor is started up) and detected

b

reakdown of the low voltage switch for continuous 30 seconds,

a fault is reported. The unit can be restored automatically after

the first 2 reported faults within 30 minutes. The third reported

fault and so on can not be restored automatically.

E4

Compressor Exhaust High

Temperature Protection

Discharge thermal

bulb

After the compressor is started, if discharge temperature is

detected to be more than or equal to 130 degree for continuous

30 seconds, E4 will be displayed, all loads (except for the four

way valve) will be shut off, the compressor will stop for 3

minutes and the complete system will restore after discharge

temperature is lower than 90 degree. If such fault is reported for

successive three times, the protection can not be restored itself.

E5

Compressor

Overheat

Compressor

After the compressor is started, if the overload switch of the

compressor is detected to shut off, the fault is reported. All loads

(except for the four way valve) are shut off, the fault is displayed,

and the compressor will stop for 3 minutes. If the fault is

removed, the compressor can be restarted to run. If successive

three compressor overload protection faults are detected within

30 minutes, the unit can not be restored itself and the buzzer will

give out an alarm. Push the ON/OFF button to shut off the unit.

And then push ON/OFF button again, if high voltage protection

disappears, operation will restore, or otherwise, the fault is

displayed.

E6

Communications

Failure

Communication

When outdoor unit is energized and fails to receive data of indoor

unit within 30 seconds, an indoor unit communication fault is

reported. The compressor and the outdoor unit will be shut off,

and the four way valve will be stopped 2 minutes after the

compressor outage in heating state.

If indoor unit fails to receive information of outdoor unit, a

communication fault is reported. The indoor unit is shut off and

an indicator is twinkling. If the display board fails to receive

information of outdoor unit, a communication fault is determined

and displayed and the unit does not actuate. After communication

b

ecomes normal, the system can restore to the previous running

state itself.

E8
