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)

Central control function, if connected with a central controller

YCZ-A001

Weekly timing function, if connected with a weekly timer YCS-A001

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

■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.
