Installation EDUS39-606A-N

10 Installation of Outdoor Units

• Before touching electrical parts, turn off the power.

• When installing or relocating the system, be sure to

keep the refrigerant circuit free from substances

other than the specified refrigerant (R-410A) such as

air.

Any presence of air or other foreign substance in the

refrigerant circuit causes an abnormal pressure rise or

rupture, resulting in injury.

• Do not reconstruct or change the settings of the pro-

tection devices.

If the pressure switch, thermal switch, or other protection

device is shorted and operated forcibly, or parts other

than those specified by Daikin are used, fire or explosion

may result.

• Placing a flower vase or other containers with water

or other liquids on the unit could result in a shock

hazard or fire if a spill occurs.

• Do not touch the switch with wet fingers.

Touching a switch with wet fingers can cause electric

shock.

• Be sure to install a ground leakage breaker.

Failure to install a ground leakage breaker may result in

electric shocks, or fire.

• Heat exchanger fins are sharp enough to cut.

To avoid injury wear glove or cover the fins when working

around them.

• Do not touch the air outlet or horizontal blades while

the swing flap is in operation because fingers can

get caught and injured.

• Do not allow children to play on or around the unit as

they could be injured.

• Refrigerant pipes may be very hot or very cold dur-

ing or immediately after operation.

Touching them could result in burns or frostbite. To avoid

injury give the pipes time to return to normal temperature

or, if you must touch them, be sure to wear proper gloves.

• While following the instructions in this installation manual,

install drain piping in order to ensure proper drainage and

insulate piping in order to prevent condensation.

Improper drain piping may result in water leakage and

property damage.

• Be very careful about product transportation.

• Do not touch the refrigerant pipes during and imme-

diately after operation.

During and immediately after operation, the refrigerant

pipes may be hot and may be cold, depending on the

condition of the refrigerant flowing through the refrigerant

piping, compressor, and other refrigerant cycle parts.

Your hands may suffer burns or frostbite if you touch the

refrigerant pipes.

• Do not remove the front panel because some parts

inside are dangerous to touch. In addition, some

parts may be damaged by touching them. For check

ing and adjust internal parts, contact your dealer.

• Do not turn off the power immediately after stopping

operation.

Always wait at least five minutes before turning off the

power. Otherwise, water leakage and trouble may occur.

• Do not use a charging cylinder.

Using a charging cylinder may cause the refrigerant to

deteriorate.

• The refrigerant R-410A requires strict cautions for

keeping the system clean, dry and tight.

A. Clean and dry

Foreign materials (including mineral oils such as

SUNISO oil or moisture) should be prevented from get

ting mixed into the system.

B. Tight

CAUTION

R-410A does not contain any chlorine, does not destroy

the ozone layer, and does not reduce the earth’s protec-

tion against harmful ultraviolet radiation.

R-410A can contribute slightly to the greenhouse effect if

it is released. Therefore we should take special attention

to check the tightness of the installation.

Read Section 6, REFRIGERANT PIPING WORK care-

fully and follow these procedures correctly.

• Since R-410A is a mixed refrigerant, the required

additional refrigerant must be charged in its liquid

state. (If the refrigerant is charged in a state of gas,

its composition changes and the system will not

work properly.)

The indoor unit is for R-410A. See the catalog for indoor

unit models which can be connected.

(Normal operation is not possible when connected to other

units.)

• For installation of the indoor units, refer to the instal-

lation manual supplied together with each indoor

unit.

• Check the unit stand for damage on a continuous

basis, especially if it has been in use a long time. If

left in a damaged condition, the unit may fall and

cause injury.

• Never operate the air conditioner with the discharge

pipe thermistor (R3T), suction pipe thermistor (R2T)

and pressure sensors (S1NPH, S1NPL) removed.

Such operation may burn out the compressor.

• Make sure to provide for adequate measures in order

to prevent that the outdoor unit be used as a shelter

by small animals.

Small animals making contact with electrical parts can

cause malfunctions, smoke or fire. Please instruct the cus-

tomer to keep the area around the unit clean.

NOTE

• Install the indoor and outdoor units, power supply wiring

and transmission wiring at least 3.5 ft. away from televi

sions or radios in order to prevent image interference or

noise.

Depending on the radio waves, a distance of 3.5ft. may not

be enough to eliminate the noise.

• Dismantling of the unit, treatment of the refrigerant, oil

and eventual other parts, should be done in accor-

dance with the relevant local and national regulations.

• Do not use the following tools that are used with con-

ventional refrigerants: Gauge manifold, charge hose,

gas leak detector, reverse flow check valve, refrigerant

charge base, vacuum gauge, refrigerant recovery

equipment.
