1 Safety Precautions
WARNING! This mark indicates procedures which, if improperly performed, might lead to the
death or serious injury of the user.
CAUTION! This mark indicates procedures which, if improperly performed, might possibly
result in personal harm to the user, or damage to property.
WARNING!
(1). For operating the air conditioner pleasantly, install it as outlined in this installation manual.
(2). Connect the indoor unit and outdoor unit with the room air conditioner piping and cord available
from our standard parts. This installation manual describes the correct connections using the
installation set available from our standard parts.
(3). Installation work must be performed in accordance with national wiring standards by authorized
personnel only.
(4). If refrigerant leaks while work is being carried out, ventilate the area. If the refrigerant comes in
contact with a ame, it produces toxic gas.
(5). Do not power on until all installation work is complete.
(6). During installation, make sure that the refrigerant pipe is attached firmly before you run the
compressor.
Do not operate the compressor under the condition of refrigerant piping not attached properly with
2-way or 3-way valve open.
This may cause abnormal pressure in the refrigeration cycle that leads to breakage and even
injury.
(7). During the pump-down operation, make sure that the compressor is turned off before you remove
the refrigerant piping.
Do not remove the connection pipe while the compressor is in operation with 2-way or 3-way
valve open.
This may cause abnormal pressure in the refrigerant cycle that leads to breakage and even injury.
(8). When installing and relocating the air conditioner, do not mix gases other than the specified
refrigerant (R410A) to enter the refrigerant cycle.
If air or other gas enters the refrigerant cycle, the pressure inside the cycle will rise to an
abnormally high value and cause breakage, injury, etc.
(9). This appliance is not intended for use by persons (including children) with reduced physical,
sensory or mental capabilities, or lack of experience and knowledge, unless they have been
given supervision or instruction concerning use of the appliance by a person responsible for their
safety.
(10). Children should be supervised to ensure that they do not play with the appliance.
(11). If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or

4.4 Vacuum and Gas Leakage Inspection
CAUTION!
Do not purge the air with refrigerants but use a vacuum pump to vacuum the installation! There is
no extra refrigerant in the outdoor unit for air purging!
4.4.1 Vacuum
(1). Remove the caps of the liquid valve, gas valve and also the service port.
(2). Connect the hose at the low pressure side of the manifold valve assembly to the service
port of the unit’s gas valve, and meanwhile the gas and liquid valves should be kept closed
in case of refrigerant leak.
(3). Connect the hose used for evacuation to the vacuum pump.
(4). Open the switch at the lower pressure side of the manifold valve assembly and start the
vacuum pump. Meanwhile, the switch at the high pressure side of the manifold valve
assembly should be kept closed, otherwise evacuation would fail.
(5). The evacuation duration depends on the unit’s capacity, generally, 15 minutes for the
09K/12K units, 20 minutes for the 18K units, 30 minutes for the 24/30/36K units, 45
minutes for the 42/48/60 units. And verify if the pressure gauge at the low pressure side
of the manifold valve assembly reads -1.0Mp (-75cmHg), if not, it indicates there is leak
somewhere. Then, close the switch fully and then stop the vacuum pump.
(6). Wait for some time to see if the system pressure can remain unchanged, 3 minutes for the
units less than 18K, 5 minutes for the 18K~24K units, 10 minutes for the units more than
42K. During this time, the reading of the pressure gauge at the low pressure side can not
be larger than 0.005Mp (0.38cmHg).
(7). Slightly open the liquid valve and let some refrigerant go to the connection pipe to balance
the pressure inside and outside of the connection pipe, so that air will not come into the
connection pipe when removing the hose. Note that the gas and liquid valve can be opened
fully only after the manifold valve assembly is removed.
(8). Place back the caps of the liquid valve, gas valve and also the service port.

During evacuation, it is available to connect two hoses of the manifold valve assembly to two
service ports to quicken the evacuating speed.
4.4.2 Additional Charge
Refrigerant suitable for a piping length of 5m is charged in the 09~42K outdoor unit at the
factory, and for 48~60K outdoor unit refrigerant is charged for a piping length of 7.5m.
When the piping of 09~42k unit is longer than 7.5m or the piping of 48~60k unit is longer than
9.5m, additional charging is necessary.
For the additional amount, see Table 8.
