Confirm that the drainage ditch can drain smoothly.
Check if the leakage protection switch is installed. The earth leakage protection switch must be installed. If it is not installed, it may cause
electric shock.
Do not install in a place where flammable gases are easily leaked. In the event of a flammable gas leak, it may cause a fire if it is trapped
around the indoor unit.
Confirm that the installation base and hoisting are firm and reliable. If the foundation and hoisting are not strong enough, it may fall and
cause an accident.
Connect the cables correctly. If the cables are not correctly connected, electrical parts may be damaged.
Exposing the unit to water or other moisture before installation may cause short-circuiting of electrical components. Do not store it in a wet
basement or expose it to rain or water.
If the refrigerant leaks during installation, immediately ventilate the room. If the refrigerant gas leaks out and comes into contact with the
fire, it may produce toxic gases.
After the installation is completed, check and confirm that the refrigerant is not leaked.
If the refrigerant gas enters the room and comes into contact with a fire source such as a heater, stove or rice cooker, it may produce toxic
gases.
Please install the lightning protection device according to the national laws and regulations, otherwise the machine may be damaged by
lightning.

2.1 Arrival of Goods(AOG) and Out of Box Audit(OOBA)
1) After receiving the machine, check for transport damage. If damage is found on the surface or inside, it should be
reported to the transportation company immediately in written form.
2) After receiving the machine, check whether the model, specification and quantity of the equipment are in accordance
with the contract.
3) When unpacking, please keep the operating instructions and check the accessories.
. Refrigerant piping
1) The refrigerant piping shall use pipeline with specified diameter and wall thickness.
2
2) When the copper tube is welded, it must be filled with nitrogen. Before welding, it is filled with 0.2 kgf /cm of nitrogen.
After the welding is completed, wait until the copper tube is completely cooled and stop the nitrogen supply.
3) The refrigerant piping must be insulated.
4) After the refrigerant piping is installed, the indoor unit cannot be energized until the airtightness test and vacuuming
are performed.
2.3 Air tightness test
2
After the refrigerant piping is installed, it is necessary to inject nitrogen at a pressure of 40 kgf/cm (4.0MPa) from the gas
side and the liquid side for a 1-hour air tightness test.
2.4 Vacuum treatment
After the air tightness test, vacuum treatment must be carried out simultaneously from both sides of the gas and liquid
(vacuum treatment should reach -0.1 MP a).
2.5 Refrigerant adding
1) Calculate the amount of refrigerant added based on the pipe diameter and length (solid length) of the liquid side piping
of the outdoor unit and the hydraulic module.
2) The amount of refrigerant added, the diameter of the liquid pipe, the length (actual length), and the difference between
the indoor and outdoor units shall be recorded in advance on the outdoor unit's use confirmation form (on the cover of
electrical control box) for later review.
2.6 Electrical wiring
1) Please select the power supply capacity and wire diameter according to the design manual. The power cord of the air
conditioner is thicker than the power cord of the general motor.
2) To prevent malfunction of the air conditioner, be careful not to make the power cords (220v) to be interleaved and
entangled with the connecting wire of indoor and outdoor unit (low voltage wiring).
3) After performing the airtightness test and vacuum pumping, energize the hydraulic module.
2.7 Trial run
Test run can only be performed after at least 3 hours preheating, otherwise the system will be damaged.

outdoor unit.
3) Confirm that the vacuum pump can work below - 0. 1 MPa after running for more than 1 hour. If it cannot work below -
0.1 MPa after running for more than 2 hours, it indicates that there is moisture or gas leakage inside and needs to be
checked.
4) The vacuum pump must be equipped with a check valve.
Connect vacuum pump
Run the vacuum pump (more than 30 minutes)
After the complete vacuuming and the pressure reaches-
0.1MPa, the vacuum pump continues to run for 20 minutes.
Vacuum pump stops
Place in vacuuming state (more than 1 hour)

6 Test run
6.1 Inspection before commissioning
1) Check and confirm that the cooling pipes and communication lines for the hydraulic module and the outdoor unit are
connected to the same refrigeration system. Otherwise, an operational failure will occur.
2) The power supply voltage is within ± 10% of the rated voltage.
3) Check and confirm that the power cable and control cable are wired correctly.
4) Before powering up, check and confirm that there is no short circuit in each line.
2
5) Check whether all units have passed the 24-hour nitrogen pressure maintaining test (40 kgf/cm ).
6) Check and confirm that the system to be commissioned has been vacuum dried and filled with refrigerant as required.
6.2 Preparation before commissioning
1) Calculate the amount of refrigerant to be added to each unit according to the length of the liquid pipe on site.
2) Prepare the required refrigerant.
3) Prepare the system plan, system piping diagram and control circuit diagram.
4) Record the set address code on the system plan.
5) Turn on the outdoor unit power switch in advance to ensure that it is turned on for more than 3 hours to heat the
compressor oil.
6) Fully open the gas pipe shut-off valve, liquid pipe shut-off valve and oil balance valve of the outdoor unit. If not fully
opened, the machine will be damaged.
7) Check if the power phase sequence of the outdoor unit is correct.
8) Check that all the DIP switches of the outdoor unit and hydraulic module have been set according to the product
technical requirements.
6.3 Precautions against refrigerant leakage
1) The refrigerant used for the air conditioner is a harmless and non-combustible safety refrigerant.
2) The air conditioner shall be placed in a room with sufficient space. Even if a refrigerant leak occurs, the limit of
concentration will not be exceeded. Necessary measures can be taken depending on the situation.
3
3) The concentration limit of the gas that does not cause harm to the human body is: 0.3 [kg/m ].
4) Confirm the concentration limit below and take the necessary measures.
a) Calculate the total filling amount of the refrigerant (A [kg] )
Total amount of refrigerant = the amount of refrigerant filled when delivery (see nameplate) + the
additional amount of refrigerant according to the length of the piping
3
b) Calculate the indoor volume (B[m ]) (calculated by the minimum volume)
c) Calculate the refrigerant concentration
5) Countermeasures when the concentration limit is exceeded
a) To reduce the concentration of the refrigerant below the concentration limit, please install a mechanical
ventilator(for frequent ventilating).
b) When it is not possible to change the air frequently, please install a leak detection alarm device interlocked with the
mechanical ventilator.
b. Leak detection alarm device interlocked with mechanical ventilator

module
a. Ventilation opening
(The leak detection alarm device should be installed in a
place where the refrigerant is easily retained.)

6.4 Hand over to the customer
1) Be sure to give the “User Manual” of the hydraulic module and the “Installation Manual” of the outdoor unit to the
customer.
2) Explain the contents of the “Operation and Installation Manual” to the customer in detail.
