FOR SERVICE

PERSONNEL ONLY

• Carefully read through the

procedures of proper installation

before starting installation work.

• The sales agent should inform

customers regarding the correct

operation of installation.

Tools Needed For Installation Work

( mark is tool exclusive use for R32) ● Screwdriver ● Measuring Tape ● Knife ● Saw

● Pipe Cutter ● Hexagonal Wrench Key ( 4mm) ● Power Drill (ø 65mm ~ ø 80mm) Vacuum

Pump ● Pliers or Wrench ● Torque Wrench Vacuum Pump Adaptor ● Flare Tool Gas

Cooling & Heating

• Please request your sales agent or qualied technician to install your unit. Water leakage,

short circuit or re may occur if you do the installation work yourself.

• Please observe the installation stated in the installation manual during the process of

installation. Improper installation may cause water leakage, electric shock and re.

• Make sure that the units are mounted at locations which are able to provide full support to the

weight of the units. If not, the units may collapse and impose danger.

• Observe the rules and regulations of the electrical installation and the methods described in

the installation manual when dealing with the electrical work. Use cables which are approved

o󰀩cial in your country. Be sure to use the specied circuit. A short circuit andre may occur

due to the use of low quality wire or improper work.

• Be sure to use the specied cables for connecting the indoor and outdoor units. Please

ensure that the connections are tight after the conductors of the wire are inserted into

the terminals to prevent the external force is being applied to the connection section of

theterminal base. Improper insertion and loose contact may cause over-heating and re.

• Please use the specied components for installation work. Otherwise, the unit may collapse

or water leakage, electric shock, re or stronger vibration may occur.

• Be sure to use the specied piping set for R32. Otherwise, this may result in broken copper

pipes or faults.

• When installing or transferring an air conditioner to another location, make sure that air other

than the specied refrigerant (R32) does not enter the refrigeration cycle. If other air should

enter, the pressure level of the refrigeration cycle may increase abnormallywhich could result

in a rupture and injury.

• Never install a drier to this R32 unit in order to guarantee its lifetime.

• Be sure to ventilate fully if a refrigerant gas leak while at work. If the refrigerant gas comes

into contact with re, a poisonous gas may occur.

• After completion of installation work, check to make sure that there is no refrigeration gas

leakage. If the refrigerant gas leaks into theroom, coming into contact with re in the fan-

driven heater, space heater, etc., a poisonous gas may occur.

• Unauthorized modications to the air conditioner may be dangerous. If a breakdown occurs

please call a qualied air conditioner technician or electrician. Improper repairs may result in

water leakage, electric shock and re, etc.

• Be sure to connect the earth line from the power supply wire to the outdoor unit and

between the outdoor and indoor unit. Do not connect the earth line to the gas tube,

water pipe, lighting rod or the earth line of thetelephone unit. Improper earthing may

cause electric shocks.

WARNING

CAUTION

WARNING

• When nishing the refrigerant collection (pumping down), stop the compressor and then remove the coolant pipe.

If you remove the refrigerant pipe while the compressor is operating and the service valve is released, air is sucked and apressure in

the freezing cycle system will build up steeply, causing an explosion or injury.

• When installing the unit, be sure to install the refrigerant pipe before starting the compressor.

If the refrigerant pipe is not installed and the compressor is operated with the service valve released, air is sucked and thepressure

level of the refrigeration cycle may increase abnormally which could result in a rupture and injury.

• The electric cables should neither be reworked nor added. Make sure to use an exclusive circuit breaker. Otherwise re or electric

shock might occur by connection failure, isolation failure or over current.

• Make sure to connect cables to terminal properly and terminal cover should close rmly.

Otherwise, over heating at terminal contact, re or electric shock might occur.

• Make sure that there is no dust on any connected points of electric cables and x rmly.

Otherwise, re or electric shock might occur.

● A circuit breaker or fuse must be installed. Without a circuit breaker or fuse the danger of electric shock exists.

The external switch shall be incorporated to completely disconnect from power supply. It should disconnect all poles,

and a contact separation of at least 3mm must be present.

● Do not install the unit near a location where there is ammable gas. The outdoor unit may catch re if

ammable gas leaks around it.

● Do not install the indoor unit in a machine shop or kitchen where vapor from oil or its mist flows to the indoor

unit. The oil will deposit on the heat exchanger, thereby reducing the indoor unit performance and may deform

and in the worst case, break the plastic parts of the indoor unit.

● Please ensure smooth flow of water when installing the drain hose. Improper installing may wet your furniture.

● Piping shall be suitable supported with a maximum spacing of 1m between the supports.

● Do not use means to accelerate the defrosting process or to clean, other than those recommended by the

manufacturer. Any unt method or using incompatible material may cause product damage, burst and serious injury.

● The appliance/pipe-work shall be stored in a well ventilated room with indoor oor area larger than Amin [refer to

Table 1] and without any continuously operating ignition source. Keep away from open ames, any operating gas

appliances or any operating electric heater. Else, it may explode and cause injury or death.

● The appliance/pipe-work shall be installed, and/or operated in a room with floor area larger than Amin [refer to Table

1] and keep away from ignition sources, such as heat/spark/open flame or hazardous areas such as gas appliances,

gas cooking, reticulated gas supply systems or electric cooking appliances, etc.

● Do not pierce or burn as the appliance/pipe-work is pressurized. Do not expose the appliance/pipe-work to heat,

flame, sparks, or other sources of ignition. Else, it may explode and cause injury or death.

● The contents of this section are vital to ensure safety. Please pay special attention to the following sign.

Be sure that the unit operates in proper condition after installation. Explain to customer the proper operation and maintenance of

the unit as described in the user’s guide. Ask a customer to keep this installation manual together with the instruction manual.

WARNING ........ Incorrect methods of installation may cause death or serious injury.

CAUTION ......... Improper installation may result in serious consequence.

Make sure to connect earth line.

This sign in the figures indicates prohibition.

WARNING

● The Outdoor unit must be mounted at a location which can support

heavy weight. Otherwise, noise and vibration will increase.

CAUTION

● Do not expose the unit under direct sunshine or rain. Besides,

ventilation must be good and clear of obstruction.

● The air blown out of the unit should not point directly to animals or

plants.

● The clearances of the unit from top, left, right and front are specied

in gure below. At least 3 of the above sides must be open air.

CONDENSED WATER DISPOSAL OF OUTDOOR UNIT

● There are holes on the base of Outdoor unit for condensed water to exhaust.

● In order to ow condensed water to the drain, the unit is installed on a stand or a block so that the unit is 100mm above the ground as

shown gure. Join the drain pipe to one hole.

● At rst insert one portion of the hook to the base (Portion A), then pull the drain pipe in the direction shown by the arrow while inserting

the hook into the base. After installation, check whether the drain pipe cling to the base rmly.

When Using and Installing In Cold Areas

When the air conditioner is used in low temperature and in snowy conditions, water from the heat exchanger may freeze on the base surface

to cause poor drainage. When using the air conditioner in such areas, do not install the bushings. Keep a minimum of 250mm between the

drain hole and the ground. When using the drain pipe, consult your sales agent.

For more details, refer to the installation Manual for Cold Areas.
