Safety Information

California Proposition 65 Warning (US)

WARNING: Cancer and Reproductive Harm -

www.P65Warnings.ca.gov.

WARNING

Before installation, maintenance, and cleaning, be sure to cut

off the power supply.

The installation shall be conducted by the dealer or qualified

personnel.

• If installed by a unqualified person, it may cause leaks,

electric shock, or fire.

Be sure to install the product by following the instructions in

this manual.

• If not installed properly, it may cause leaks, electric shock,

or fire.

The LAC KIT manufacturer does not assume any responsibility

for losses or damages caused by careless installation or

installation by a unqualified person.

For installation, be sure to use the provided parts and the

specified parts and tools.

• If the specified tools are not used, it may cause a fall of the

product, leaks, electric shock, or fire.

If the power cable is damaged, be sure to let the cable

replaced by the manufacturer, service engineer, or person

with equivalent qualification.

DB68-06398A-01_IM_ACC 옵션 저온냉방 Kit_AA_EN_.indd 3DB68-06398A-01_IM_ACC 옵션 저온냉방 Kit_AA_EN_.indd 3 2022-09-08 오후 1:53:022022-09-08 오후 1:53:02

The electrical work shall be conducted by the qualified

personnel after following Technical Standards for Electrical

Equipment, Extension Regulations, and Installation Manual.

Additionally, be sure to follow the electrical specifications.

• The voltage drop, lack of voltage supply, inadvertent power

work, and use of unspecified wires may cause electric shock

or fire.

When wiring the power connection between LAC KIT and

outdoor units, the lines must be fixed not to allow movement

of structures such as cover of electrical unit. In addition, be

sure to fix the cover of electrical unit onto the product.

• If the cover of electrical unit is not securely fixed, it may

cause heating of connectors, electric shock, or fire.

For wiring, be sure to use the specified lines and firmly fix

them not to allow any external force to the connectors.

• Insecure connection and fixing may cause heating or fire.

Be cautious not to exceed the power limit of LAC KIT or supply

power less than the minimum voltage.

• Damage or dysfunction of any electrical part may cause

product failure.

Be sure to use the power cable made of copper and use only

the rated parts.

Then check the wiring status.

• It may cause fire due to heating.

CAUTION

Be sure to conduct ground work.

• The ground wire shall not contact the following: gas pipes,

water pipes, lightning rod, and telephone grounding wire.

• An incomplete grounding may cause electric shock.

Be sure to place the power and communication lines of LAC

KIT at least 1 m apart from other electronic devices and at

least 2 m apart from the lightning rod's down conductor.

• Note that noise may occur even in the distance over 1 m

depending on the radio interference status.

Do not install the product in the following places:

• The place is filled with mineral oil, scattering oil, or steam

(e.g. kitchen): Heated resin parts may cause fall of the

product or leaks.

• The place generates corrosive gases such as sulfur dioxide

(e.g. Room with vents): Corrosion of copper pipes and joints

may cause refrigerant leak.

• There is equipment that generates electromagnetic waves:

Abnormal operation may be resulted due to malfunction of

the controller.

• Flammable gases may leak, carbon fiber dust or flammable

gas is floating, and volatile matters such as thinner and

gasoline are used: Leak gas may reside in the main valve,

which may cause a fire.

• In the place, an indoor unit may be corroded. (e.g. shore,

spa, etc.)

• The place is directly affected by external factors

(temperature, humidity, dust, etc.).

ÚInstallation-related claims caused by non-compliance with

above requirements are on your own responsibility.

(Service cost must be paid by you.)

Installing LAC KIT

Assembling the Assy Control Kit and Low Ambient Damper

1. Connect the actuator to TRANS.

– Place the actuator and TRANS on the Assy controller kit as shown in the figure and then

fix them on the plate with bolts, nuts, and screws.

Note

• Assemble them with the same alignment and rotation for the actuator as the figure below.

If its alignment and rotation are not correct, it may cause malfunction.

Note

• The direction of the actuator can be changed as follows:

ÚBefore installation on field, it must be assembled.

Assemble the control box and the control kit.

• The control kit must be taken into the

control box. (Check the fitting holes.)

• The UL certification must be acquired.

• When the louver actuator shaft enters into

the box, prevent water penetration. (Use a

bushing and such.)

• When assembling the control kit, use the

boss with12 mm or above in size.

(The heat transfer distance between the

control kit and control box must be 12 mm

or above.)
