DIGITAL SCROLL CENTRAL AIR CONDITIONER (OUTDOOR UNIT) YDS SYSTEM R410A

For correct installation, read this manual before starting installation.Only trained and qualified service personnel should install, repair or service air conditioning equipment. Users

should not install the air conditioner by themselves. All pictures are only sketches. If there is any difference between pictures in this manual and the actual shapeof the air conditioner you purchased, the actual shape shall prevail.

PRECAUTIONS

1. This installation manual is for the outdoor unit.2. Refer to the indoor unit installation manual for indoor parts

installation.3. Please read the power source unit installation manual to

install the power source unit .4. Please refer to the refrigerant distributor installation

manual to install the refrigerant distributor.

KEY POINTS IN INSTALLATION

INSTALLATION

Confirm the model and name of your air conditioner to avoid installation mistakes.

REFRIGERANT PIPING

Separately purchased refrigerant distributor (branch joint, branch header pipe) should be used in the processof refrigerant piping.

Charge nitrogen under certain pressure in the refrigerantpiping before welding.Heat insulation should be done to refrigerant piping.

After the installing refrigerant piping, do not electrify theindoor unit before the airtight test and vacuum.

Refrigerant piping should accord with specifieddiameter.

AIRTIGHT TEST

Refrigerant piping must be tested for gas proof 2[3.8MPa(40kgf/cm ) nitrogen.]

VACUUM

Vacuum pump must be used, and vacuuming shouldbe done from the gas side and liquid side

simultaneously.ADD REFRIGERANT

When the actual pipe is longer than the fiducial length,the added refrigerant volume of every outdoor unitdepends on the calculating according to the actual length.Fill the form on the outdoor unit electric control box withthe added volume, length of pipes (actual length) and therelative height drop between outdoor unit and indoor unit.

WIRING

Choose power capacity and wire diameter according tothe design manual. The power cord of the air conditioner

should be wider than the power cord of ordinary motor.

Connect the indoor unit to the power after airtight testand vacuuming.

Do not twist or cross the power cord (380V 3N~)withwiring (low voltage) between indoor and outdoor unit, or mishandling may occur.

Set the address of outdoor unit, see Address dialof outdoor unit

TEST RUNNING

The test running can not begin until the outdoor unit hasbeen connected to the power for 12hr.

Remove six sponges at the back of unit. Please handlewith care to avoid damage to fin, which will decreaseheat exchanging efficiency.

1. Please keep away from the following place, or malfunction of the machine may be caused:

2. The insulation of the metal parts of the building and theair conditioner should comply with the regulation of National Electric Standard.

CAUTION

There is combustible gas leakage.There is much oil (including engine oil) ingredient.

There is salty air surrounding(near the coast)There is caustic gas (the sulfide) existing in the air (near a hotspring).

A place the heat air expelled out from the outdoor unitcan reach your neighbor's window.

A place that the noise interferes your neighbors everyday life.

A place that is too weak to bear the weight of the unit.Uneven place.Insufficient ventilation place.Near a private power station or high frequency equipment.

A place with strong electromagnetic interference.

NOTE: The top of any pile around the outdoor unit should at least 800 mmbelow the top of unit. If not, plea se install mechanical air discharge equipment.

REFRIGERANT PIPE

1. Refrigerant piping connection is inside the outdoor unit, please remove the front clapboard.

2. The piping can be led through the down-left of theoutdoor unit or the soleplate gap.

3. When through the front, piping is led by wiring fromthe panel, then connect branch pipes towards leftor right.

4. When through the soleplate gap, install the branchpipe towards left, right or back.

5. If through the front, please remove the clapboardat corresponding place first.

To prevent the inside of piping from oxidizingwhen welding, it is necessary to charge nitrogen,or oxide may block the circulation.
