1.4 Product features

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

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 temperature cooling realized, super low temperature heating

realized.

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.

Note :

(1) Fix the parts with screws

(2) Don't intake the strong wind directly to the

outlet air-flow hole.

(3) A one meter distance should be kept from the

unit top

(4) Don't block the surroundings of the unit with

sundries

2. Selection of the place of installation

1.

Accessories

"Edging" for protection of electric wires from an

opening edge.

Select the place of installation satisfying the following conditions and, at the

same time, obtain a consent from the client or user.

Edging

Place where air circulates.

Place free from heat radiation from other heat sources.

Place where drain water may be discharged.

Place where noise and hot air may not disturb the neighborhood.

Place where there is not heavy snowfall in the winter time.

Place where obstacles do not exist near the air inlet and air outlet .

Place where the air outlet may not be exposed to a strong wind.

Place surrounded at four sides are not suitable for installation. A 1m or more

of overhead space is needed for the unit.

Mount guide-louvers to place where short-circuit is a possibility.

When installing several units, secure sufficient suction space to avoid short

circuiting.

Electric wiring work should be conducted only by authorized personnel.

Do not connect more than three wires to the terminal block. Always use round

type crimped terminal lugs with insulated grip on the ends of the wires.

Use copper conductor only.

Select wire sizes and circuit protection from table below. (This table shows 20 m

length wires with less than 2% voltage drop.)

4. Installation of water drainage pipe

(1) Install water drainage pipe

Pipe diameter shall be equal or larger than that of connecting pipe (Pipe of polythene; size: 25mm;

O.D.: 32mm )

Drainpipe should be short, with a downward slope at least 1/100 to prevent air bag from forming.

If downward slope of drainpipe cannot be made,lifting pipe shall be installed.

Keep a distance of 1-1.5m between suspending bolts, to make water hose straight.

Use the drainage hose and clip provided with unit.

Insert water pipe into water plug until it reaches the white tape.

Tighten the clip until head of the screw is less than 4mm from hose.

Wind the drainage hose to the clip using seal pad for heat insulation.

Insulate drainage hose in the room.

5. Cautions for the water drainage lifting pipe

Installation height of water drainage lifting pipe shall be less than 280mm

There should be a right angle with unit ,300mm from unit.

If several water hoses join together, of as per following procedures.

Specifications of the selected drainage hoses shall meet the requirements for the unit running

6. Installation of Ornament Panel

Install ornament panel on indoor unit

(1) Check whether indoor unit is horizontal with leveler or polythene pipe filled with water , and

check that the dimension of the ceiling opening is correct. Take off the lever gauge before

installing the ornament panel.

(2) Fasten the screws to make the height difference between the two sides of indoor unit less than

5mm.

(3) Firstly fix it with screws temporarily.

(4) Fasten the two temporarily fixing screws and other two, and tighten the four screws.

(5) Connect the wires of synchro-motor.

(6) Connect the wire of signal.

(7) If no response of remote controller,check whether the wiring is correct,restart remote controller

10 seconds after shut off power supply.

Slope below 1/100

Connection drainage hose with a T-joint
