Refrigerant Additional Charge
The unit has been filled with refrigerant, but need additional charge for all the connected pipes in the refrigerant system.
Adding additional refrigerant according to the connecting pipe diameter and pipe length. Refrigerant type is
R410A, additional charge is calculated as follows:
Calculate charge refrigerant quantity by liquid pipe length, charge it to refrigerant cycle.

INSTALLATION
MANUAL
1.
This air conditioner uses new refrigerant
HFC(R410A)
.
2.
Since the max. working pressure is 4.15MPa(R22:3.1MPa),some of the piping and installation and service tools are special.
3.
This air conditioner unit should be connected with the branch box or special indoor unit, allowed models please consult the
sales staff before installation .
4
.
This air conditioner uses power
supply
:
220V
-240V
,50Hz
.
·
Be sure to use a dedicated power circuit, and do not put other loads on the power supply.
·
Be sure to read these SAFETY PRECAUTIONS carefully before installation.
·
Be sure to comply with SAFETY PRECAUTIONS of installation manual, because it contains
important safety issues. Definitions for identifying hazard levels are provide below with their respective safety symbols.
WARNING
：
Hazards or unsafe practices which COULD result in severe personal injury or death.
CAUTION
：
Hazards or unsafe practices which COULD result in minor personal injury or product or puoperty damage.
CAUTION
：
·
Please carefully file indoor and outdoor unit manual away for future reference.
·
Installation should be left to the professional ,do not do it by yourself(customer).
Incomplete installation could cause damage by fire, electric shock, drop or water leakage .
Please consult your dealer or professional installation personnel.
·
Install the air conditioner on a solid base that can support the unit weight.
An inadequate base or incomplete installation may cause injury in the event the unit falls off the base.
·
Use the specified type of wires for electrical connections safely between the indoor and outdoor units.
And firmly connected to the connection part of wire terminals , so that the wire stress will not be applied to these parts.
Incomplete connection may cause fire.
·
For wiring, use a cable long enough to cover the entire distance with no connection.
And don't connect multiple devices to the same AC power supply.
Otherwise, it may be due to bad contact, poor insulation, exceed the allowable current and cause a fire or electric shock.
·
After all installation is complete, check to make sure that no refrigerant is leaking out.
If the refrigerant gas leakage to the interior, and the heater, stove flame touching it, will generate harmful substances.
·
Perform the installation securely referring to the installation manual.
Incomplete installation could cause a personal injury due to fire, electric shock, the unit falling or leakage of water.
·
In accordance with the installation instructions for electrical work, please be sure to use a dedicated line.
·
If the power supply circuit capacity or electrical work is not in place, may cause a fire or electric shock.
·
Attach the electrical cover to the indoor unit and the service panel to the outdoor unit securely.
·
If the electrical cover in the indoor unit or the service panel in the outdoor unit are not attached securely, it could result in a fire or
an electric shock due to dust water, etc.
·
Please be sure to cut off the main power supply before the installation of indoor electronic PCB or wiring .
Otherwise it will cause electric shock.
·
The device should be in accordance with the state provisions for installation wiring.
·
The indoor appliance should be placed not in the children's height -- at least above ground 2.5m.
·
The outdoor machine installation location should pay attention to the protection, avoid people or other small animals contact with electrical
components, please keep the outdoor unit of the surrounding environment clean and tidy.
·
When installing or relocating the unit, make sure that no substance other than the specified refrigerant(R410A) enters the refrigerant circuit.
Any presence of foreign substance such as air can cause abnormal pressure rise or an explosion.
·
Perform earthing
Do not connect the earth wire to a gas pipe, water pipe, lightning rod or telephone earth wire.
Defective earthing could cause an electric shock.
·
Do not install the unit in a place where an inflammable gas leaks.
If gas leaks and accumulates in the area surrounding the unit, it could cause an explosion.
·
Fasten a flare nut with torque wrench as specified in this manual.
When fastened too tight, a flare nut may break after a long period and cause a leakage of refrigerant.
·
Install an earth leakage breaker depending on the installation place(where it is humid).
If a earth leakage breaker is not installed, it could cause an electric shock.
·
Perform the drainage/piping work securely according to the installation manual.
·
If there is a defect in the drainage/piping work, water could drop from the unit and household goods could be wet and damaged.
·
Hanging Method
When hanging the unit, ensure a balance of the unit, check
safety and lift up smoothly.
（

）
Do not remove any packing materials.
（
2
）
Hang the unit under packing condition with two ropes,
as shown in Fig. blow.
·
Hanging
If have no package to move,Please protect with
cloth or paper.
·
Where it is not exposed to strong wind.
·
Where airflow is good and clean.
·
Where it is not exposed to rain and direct sunshine.
·
Where neighbors are not annoyed by operation sound or hot air.
·
Where rigid wall or support is available to prevent the increase of operation sound or vibration.
·
Where there is no risk of combustible gas leakage.
·
Where it is at least 3m away from the antenna of TV set or radio. An amplifier may be required for the affected device.
·
Install the unit horizontally.
·
Please install it in an area not affected by snowfall or blowing snow. In areas with heavy snow, please install a canopy, a pedestal
and/or some baffle boards.
Before choosing the installation site, obtain user approval.
Avoid the following places for installation where air conditioner trouble is liable to occur.
·
Where there is much machine oil.
·
Salty places such as seaside.
·
Where sulfide gas is generated such as a hot spring.
·
Where there is high-frequency or wireless equipment.
Note:
When operating the air conditioner in low outside temperature, be sure to follow the instruction describe below.
·
Never install the outdoor unit in a place where its air inlet/outlet side may be exposed directly to wind.
·
To prevent exposure to wind, install the outdoor unit with its air inlet side facing the wall.
·
To prevent exposure to wind, it is recommended to install a baffle board on the air outlet side of the outdoor unit.
FREE SPACE REQUIRED AROUND OUTDOOR UNIT(Unit:mm)
Before connect with outdoor and indoor/ branch box, DO confirm the maximum allowed length of pipeline
.
Obstacles
When there is an obstacle around the outdoor unit, it does not matter if the position of the obstacle as shown in the figures below.
·
When installing the unit in an area that is enclosed on four sides such as a verandah, be sure to leave move than 200mm behind the unit .
·
When there is a lack of airflow or there is a possibility of becoming short cycle, install an outlet guide and make sure there is enough space
behind the rear side of the air inlet.
NOTE:
Make sure not to install several outdoor units sideways next to each other.
Refrigerant piping is short, the better. So the connecting pipe should be as short as possible.
·
Be sure to fix the unit’s legs with bolts when installing it.
·
Be sure to install the unit firmly to ensure that it does not fall by earthquake or gust.
·
The anchor bolts, nuts and washers for the installation areuser prepared
.
