1.4 Product features
Newly designed V- appearance indoor unit
The wall mounted type indoor unit adopts the newly designed V appearance, more fashion, more
beautiful.
Adopt the much friendlier refrigerant R410a
The air conditioner system adopts the greatly friendly refrigerant R410a, which is protective for the
ozone layer and is good to avoid the earth getting warmer. Benefit for the environment.
Adopt the advanced DC inverter technology
The system adopts the advanced DC inverter technology, which can consume less power energy to
realize the equal efficiency, saving money for you.
Smart newly designed infrared remote controller
The unit can be controlled by the newly designed infrared remote controller YR-H49, which can
realizes many functions such as heating, cooling, fan, swing, fresh, health, negative ion. Furthermore,
the remote controller can be fixed with a remote controller holder.
Negative ion function
The unit can realize the negative ion generation function, releasing the healthy negative ion into the
indoor room. You will feel more comfortable, just like in the nature.
Auto–restart function (optional)
All indoor units have auto-restart function. When the power supply cut off suddenly, the unit will
automatically recover the previous running mode once the power supply is on.
Low ambient cooling kit (optional)
Group control function (with a group controller YR-E12)

1.5 New friendly refrigerant R410A introduction:
■R410A
The working pressure of R410A is approximately 1.6 times higher than R22. Because the oil in the
refrigerant is different, please do not mix them.
Refrigerant R22 (single) R410A (mixed) R407C (mixed)
Oil Mineral oil (SONTEX 200LT) Synthetic oil (POE oil) Synthetic oil (POE oil)
Pressure ratio 1 Approx. 1.6 Approx. 1.1
■Operation flow
1. Calculate the refrigerant additional charging
amount, and charge a suitable amount.
1. Air purging by refrigerant is prohibited seriously
2. Use a special vacuum pump with reverse check
mechanism
1. Charge the nitrogen to the set pressure
2. 24 hours later,check if the pressure in the pipe
has reduced
1. Do not connect the power supply
1. Use piping material of the specified thickness
2. Do not use dirty pipe
3. Always flow nitrogen during welding work

■Piping material
1. Use the correct refrigerant piping and materials for R410A
2. For the pipe wall thickness, see the table below:
Pipe diameter Φ6.35 Φ9.52 Φ12.7 Φ15.88 Φ19.1
Pipe wall thickness 0.8 0.8 0.8 1.0 1.2
Note: Always observe and comply with the local regulations when installing the refrigerant piping.
■Tools
R410A work requires a number of special tools (* symbol). Since the tools used in R22 work
cannot be used for R410A, provide the tools separately.
Tool name Process and application
Pipe cutter Piping cutting
*Flaring tool Pipe flaring work
*Torque wrench Flare nut connection
Expander Expansion at pipe connection
Pipe bender Pipe bending work

■Work precautions
Refrigerant check: Before work, check the used refrigerant and prepare materials matched to the
refrigerant.
Refrigerant piping: Observe the basics of refrigerant piping to avoid the unnecessary problems. In
addition, when performing the welding work, seal in the nitrogen gas to the pipes, and prevent it
from the oxidation.
Leak pressure detection: Perform seal detection and make sure there is no refrigerant leakage.
Vacuum drying: If the vacuum pump has not the reverse flow check mechanism, use the pump
together with a reverse flow check adapter.
Additional refrigerant: Charge a suitable amount of refrigerant with a special R410A gauge
manifold and charging hose.

3. Safety precaution
Carefully read the following information in order to operate the airconditioner correctly.
Below are listed three kinds of Safety Cautions and Suggestions.
WARNING!
CAUTION! Incorrect operations may result in injuries or machine damages; in some cases may
cause serious consequences.
Incorrect operations may result in severe consequences of death or serious injuries.
INSTRUCTIONS: These information can ensure the correct operation of the machine.
Be sure to conform with the following important Safety Cautions.
The Safety Cautions should be at hand so that they can be checked at any time when needed.
If the conditioner is transferred to the new user, this manual should be as well transferred to the new user.
WARNING!
If any abnormal phenomena is found
(e. g.smell of firing), please cut off the
power supply immediately, and contact
the dealer to find out the handling
method.
Don't dismantle the outlet of the
outdoor unit.
The exposed fan is very dangerous
which may harm human beings.
switch
off
In such case, to continue using the
conditioner will damage the conditioner,
and may cause electrical shock or fire
hazard.
Incorrect maintenance and repairment
may cause water leak, electrical shock
and fire hazard.
When the unit needs maintenance and
repairment, please call dealer to handle it.
After the unit being used for a long time,
the base should be checked for any
damages.
If the damaged base is not repaired, the
unit may fall down and cause accidents.
