Safety precautions for installing and relocating the unit
To ensure safety, please be mindful of the following precautions.
Warning
When installing or relocating the unit, be sure to keep the refrigerant circuit free from air or substances other than the specified refrigerant. Any presence of air or other foreign substance in the refrigerant circuit will cause system pressure rise or compressor rupture, resulting in injury.
When installing or moving this unit, do not charge the refrigerant which is not comply with that on the nameplate or unqualified refrigerant. Otherwise, it may cause abnormal operation, wrong action, mechanical malfunction or even series safety accident.
When refrigerant needs to be recovered during relocating or repairing the unit, be sure that the unit is running in cooling mode.Then, fully close the valve at high pressure side (liquid valve).About 30-40 seconds later, fully close the valve at low pressure side (gas valve), immediately stop the unit and disconnect power. Please note that the time for refrigerant recovery should not exceed 1 minute. If refrigerant recovery takes too much time, air may be sucked in and cause pressure rise or compressor rupture, resulting in injury.
During refrigerant recovery, make sure that liquid valve and gas valve are fully closed and power is disconnected before detaching the connection pipe. If compressor starts running when stop valve is open and connection pipe is not yet connected, air will be sucked in and cause pressure rise or compressor rupture, resulting in injury.
When installing the unit, make sure that connection pipe is securely connected before the compressor starts running. If compressor starts running when stop valve is open and connection pipe is not yet connected, air will be sucked in and cause pressure rise or compressor rupture, resulting in injury.
Prohibit installing the unit at the place where there may be leaked corrosive gas or flammable gas. If there leaked gas around the unit, it may cause explosion and other accidents.
Do not use extension cords for electrical connections. If the electric wire is not long enough, please contact a local service center authorized and ask for a proper electric wire. Poor connections may lead to electric shock or fire.
Use the specified types of wires for electrical connections between the indoor and outdoor units. Firmly clamp the wires so that their terminals receive no external stresses. Electric wires with insufficient capacity, wrong wire connections and insecure wire terminals may cause electric shock or fire.

4. The additional refrigerant oil and refrigerant charging required after prolonging connection pipe After the length of connection pipe is prolonged for 10m at the basis of standard length, you should add 5ml of refrigerant oil for each additional 5m of connection pipe. The calculation method of additional refrigerant charging amount (on the basis of liquid pipe):
Additional refrigerant charging amount = prolonged length of liquid pipe × additional refrigerant charging amount per meter
Basing on the length of standard pipe, add refrigerant according to the requirement as shown in the table. The additional refrigerant charging amount per meter is different according to the diameter of liquid pipe. See the following sheet.

Blow function setting is as shown in Fig.3.10.1
Fig.3.10.1 Blow Setting Notes:
.When the Blow function is activated, if turning off the unit by pressing On/Off or by the remote controller, the indoor fan will run at the low fan speed for 2 min, with “BLOW” displayed on the LCD. While, if the Blow function is deactivated, the indoor fan will be turned off directly.
.Blow function is unavailable in the Fan or Heating mode.

Wired Controller(Optional)
3.11 Other Functions
a. Lock Upon startup of the unit without malfunction or under the “Off” state of the unit, press and at the same time for 5s till the wired controller enters the Lock function. In this case, LCD displays .
After that, repress these two buttons at the same time for 5s to quit this function. Under the Lock state, any other button press won’t get any response. b. Memory Memory switchover: Under the “Off” state of the unit, press Mode and at the same time for 5s to switch memory states between memory on and memory off. When this function is activated, Memory will be displayed. If this function is not set, the unit will be under the “Off” state after power failure and then power recovery. Memory recovery: If this function has been set for the wired controller, the wired controller after power failure will resume its original running state upon power recovery. Memory contents: On/ Off, Mode, set temperature, set fan speed and Lock function.
4 Installation and Dismantlement
4.1 Connection of the Signal Line of the Wired Controller
Open the cover of the electric control box of the indoor unit. Let the single line of the wired controller through the rubber ring. Connect the signal line of the wired control to the 4-pin socket of the indoor unit PCB. Tighten the signal wire with ties. The communication distance between the main board and the wired controller can be up to
20 meters ( the standard distance is 8 meters)

Fig.4.2

Fig.4.2 shows the installation steps of the wired controller, but there are some issues that need

your attention.

Prior to the installation, please firstly cut off the power supply of the wire buried in the

installation hole, that is, no operation is allowed with electricity during the whole installation.

Pull out the four-core twisted pair line from the installation holes and then let it go through

the rectangular hole behind the soleplate of the wired controller.

with screws M4X25. 4) Insert the four-core twisted pair line into the slot of the wired controller and then buckle the
front panel and the soleplate of the wired controller together.

CAUTION! Please pay special attention to the followings during the connection to avoid the malfunction of the air conditioning unit due to electromagnetic interference. .Separate the signal and communication lines of the wired controller from the power cord

Wired Controller(Optional)
and connection lines between the indoor and outdoor unit, with a minimum interval of 20cm, otherwise the communication of the unit will probably work abnormally.
.If the air conditioning unit is installed where is vulnerable to electromagnetic interference,then the signal and communication lines of the wired controller must be the shielding twisted pair lines.
