3.6 Airtight Test
After the pipes between the indoor unit and the outdoor unit are connected, replenish compressed nitrogen to
perform airtight test.
NOTE:
1. The airtight test is performed by using the compressed nitrogen [2.94MPa (30kg/cm
2
G)].
2. Tighten the spool of the gas valve and liquid valve before compressing the nitrogen.
3. Compress the nitrogen at the air vent of the gas valve.
4. The gas valve and liquid valve are closed in the process of compressing the nitrogen.
5. Do not use oxygen, flammable gas or toxic gas in the airtight test.
3.7 Vacuumize
Use a vacuum pump to make a vacuum. Do not use refrigerant gas to expel air.
When making the vacuum, start from the air side.
3.8 Open All Valves
3.9 Additional Charge of Refrigerant
According to the diameter and length of the connective liquid side pipe of the outdoor unit and indoor unit,
calculate the refrigerant replenishment quantity. The refrigerant for replenishment is R410A.

3.10 Remove Trash and Moist in the Pipe
Trash and foreign matters may come into the pipe in the process of installing the refrigerant pipe. Be sure to
blow them off with nitrogen before connecting the pipe to the outdoor units.
Use high-pressure nitrogen to clean the pipelines. Do not use the refrigerant of the outdoor unit for cleaning.
3.11 Refrigerant Leak Precautions
This air conditioner uses refrigerant R410A. The R410A is safe refrigerant which is harmless and
non-flammable. The room for placing the air conditioner should have a proper space. Even if refrigerant
leakage occurs, the density threshold will not be crossed. Additional measures may also be taken.
1) Density threshold: Density of the Freon gas that does not harm the human body. Density threshold of
R410A: 0.3 [kg/m3]
Calculate the total quantity of refrigerant to be replenished (A [kg]). Total refrigerant quantity for 10HP =
refrigerant replenishment quantity upon shipment (11[kg]) + additional refrigerant replenishment
corresponding to the pipe length
Calculate out the indoor volume (B [m3]) (according to the minimum volume)
Calculate out the refrigerant density:
2) Measures against crossing of the refrigerant density threshold
In order to keep the refrigerant density below the threshold value, please install a mechanic ventilation
device. (Perform ventilation often)
In case frequent ventilation is impossible, please install the leakage detection alarm device linked with the
mechanical ventilation device.

4. Heat Insulation of the Pipe
4.1 Heat Insulation of the Pipe
In order to prevent faults caused by condensate of the refrigerant pipe and drain pipe, perform condensate
prevention and heat insulation properly.
CAUTION:
If it is forecast that high humidity/temperature environment (condensate temperature is over 23℃) may exist in the ceiling, e.g.,
inside the ceiling with slab, ceiling which is in the same environment as the outdoor air), it is necessary to apply 10mm or thicker
adiabatic wool (16~20kg/m2 ) to the refrigerant pipe and the drain pipe in addition to applying the general heat insulation
materials. Enough heat insulation materials should also be applied to the refrigerant joint and the pipe joint.
4.2 Heat Insulation of the Drain Pipe
Be sure to entwine heat insulation materials round the drain pipe which runs through the room.
Carry through heat insulation for the drain pipes thoroughly.
4.3 Heat Insulation of the Refrigerant Pipe
Please use heat-resistant materials as heat insulation materials of the air-side pipe. (e.g., EPT)
Cover heat insulation materials separately at the liquid side and the air side. Moreover, perform heat
insulation thoroughly for the air-side pipes of the indoor unit, and prevent water from dripping outside the
unit.

5. Installation of Connective Pipe
5.1 Preparation before Installation
Check the height difference between the indoor unit and the outdoor unit, and check the length and number of
bends of the refrigerant pipeline, which must meet the following requirements:
Max. Height difference....30m (If the height difference is greater than 5m, it is better to put the outdoor unit
above the indoor unit).
Max. Pipeline length.........50m.
Max. Number of bends....15.
In the process of installing the connective pipe, do not lemmas the air, dust or foreign substance intrudes
into the pipeline system.
Install the connective pipe only after fixing the indoor and outdoor units.
Keep dry when installing the connective pipe. Do not let moist intrude into the pipeline system.
5.2 Procedure of Connecting Pipes
5.2.1 Measure the required length of the connective pipe, and make the connective pipes in the
following procedure.
5.2.1.1 Connect the indoor unit first, and then connect the outdoor unit.
The pipe bend should be handled carefully, without damaging the pipe.
NOTE:
1. Before screwing up the flared nut, apply refrigerant oil at the outer surface of the pipeline flare and the taper surface of the
connection nut. Screw up the nut for 3~4 circles beforehand.
2. When connecting or disconnecting the pipeline, be sure to use two spanners concurrently.
3. Do not rest the weight of the connective pipe on the adapter of the indoor unit. Too heavy load on the adapter of the indoor unit
may deform the pipe and thus affect the cooling/heating effect.
5.2.1.2 The valve of the outdoor unit should be closed completely (as in the factory status). Every time when
connecting the pipe, screw off the nut at the valve, and connect the flared pipe (within 5 minutes). If the nut is
put away for a long time after being screwed off the valve, dust and other foreign substance may intrude into
the pipeline system and lead to fault. Before connecting the pipe, use the refrigerant to expel air out of the pipe.
5.2.1.3 After the refrigerant pipe is connected to the indoor and outdoor units, expel air as instructed in the
“Expel air” section. After expelling the air, screw up the nut at the maintenance orifice.
5.2.1.4. Precautions for the flexible part of the pipeline
The bend angle shall not exceed 90°.
The bend shall be preferably in the middle of the pipe length, and higher bend radiuses are preferred. Do not
bend the flexible pipe for over 3 times.
5.2.1.5 Bend the thin-wall connective pipe
When bending the pipe, cut out a notch of the desired size at the bend of the adiabatic pipe, and then expose
the pipe (wrap the pipe with the wrapping tape after bending it).
The radio of the elbow pipe should be as large as possible to prevent flattening or crush.
Use the pipe bender to make close elbow pipe.
5.2.1.6 Use purchased copper pipe
When the cooper pipe is purchased from the market, be sure to use the heat insulation materials of the same
type (with a thickness of over 9mm).
DM13-01.01.16en Air-cooled Package

5.2.2 Deploy the pipelines
Drill a porthole on the wall, and put the hole sheath and hole cover through the wall.
Place the connective pipe together with the indoor & outdoor connection wires. Use wrapping tape to tie
them tight. Do not let air penetrate into it lest condensation and drips of moist.
Pull the connective wrapped connective pipe from outdoor through the sheath which gets through the wall,
and lead it into the room. Lay out the pipelines carefully lest damage to the pipes.
5.2.3. Make a vacuum of connective pipeline.
5.2.4. After the above steps are completed, the spool of the valve of the outdoor unit should be
completely open, and the refrigerant pipeline of the indoor unit and the outdoor unit should be smooth.
5.2.5. Use leak detector or soap water detect leak carefully to prevent leakage.
5.2.6. Put on an adiabatic envelope (accessory) at connective pipe adapter of the indoor unit, and wrap
it tight with the wrapping tape lest condensate and leakage.

6. Installation of Drain Pipe
6.1 Install the drain pipe of the indoor unit
In order to prevent drain overflow, install a drainage controller at place 1 of the drain pipe. (The drainage
controller is designed to smoothen the drainage when the static pressure outside the unit is high, especially
at the air inlet, in addition to remove stink through the drain pipe.)
The drain of water is natural. In the construction, the external pipe of the outdoor unit slants downward at a
gradient of 1/50~1/100.
The number of bends and folds of the drain pipe should not exceed 2. Try to avoid bends in order to prevent
trash accumulation.
In the construction, do not drop trash into the drip tray or drain pipe of the indoor unit.
Upon completion of installing the drain pipe, remove the inspection panel. Put water into the drip tray to
