Caution

Ground the air conditioner.
Grounding resistance should be according to national
regulations
Do not connect the earth wire to gas or water pipes,
lightning conductor or telephone earth wire.
Incomplete grounding may cause electric shocks.

Gas pipe.
Ignition or explosion may occur if the gas leaks.

Water pipe.
Hard vinyl tubes are not effective grounds.

Lightning conductor or telephone ground wire.
Electric potential may rise abnormally if struck by lightning.

Be sure to install an earth leakage breaker.
Failure to install an earth leakage breaker may cause electric
shocks and fire.

Install drain piping according to this installation manual to
ensure good drainage, and insulate the pipe to prevent
condensation.
Improper drain piping may cause water leakage, and make the
furnitures get wet.

Install the indoor and outdoor units, power wire and connecting
wire at least 1 meter away from televisions or radios to prevent
image interference or noise.
(Depending on the radio waves, a distance of 1 meter may not
be sufficient to eliminate the noise.)

Do not rinse the outdoor unit. This may cause electric shocks or
fire.

Do not install the air conditioner in places such as the following:

Where there is mist of mineral oil, oil spray or vapour for
example a kitchen.
Plastic parts may deteriorate, and cause them to fall out or
water to leak.

Where corrosive gas, such as sulphurous acid gas, is
produced.
Corrosion of copper pipes or soldered parts may cause the
refrigerant to leak.

Where there is machinery which emits electromagnetic
waves.
Electromagnetic waves may disturb the control system, and
cause malfunction of the equipment.

Where flammable gases may leak, where carbon fiber or
ignitable dust is suspended in the air or where volatile
flammables, such as thinner or gasoline, are handled.
Such gases may cause a fire.

Where the air contains high levels of salt such as that near
the ocean.

Where voltage fluctuates a lot, such as that in factories.

In vehicles or vessels.

Where acidic or alkaline vapour is present.

Provide a logbook

In accordance with the relevant national and international codes, it
may be necessary to provide a logbook with the equipment
containing at least 

-

info on maintenance,

-

repair work,

-

results of tests,

-

stand-by periodes,

-

etc...

In Europe, EN378 provides the necessary guidance for this logbook.

INSTALLATION

Precautions for R410A

The refrigerant requires strict cautions for keeping the system
clean, dry and tight.
-

Clean and dry

Foreign materials (including mineral oils or moisture) should be
prevented from getting mixed into the system.
-

Tight

Read 

"Precautions on refrigerant piping" on page 6

 carefully and

follow these procedures correctly.

Since R410A is a mixed refrigerant, the required additional
refrigerant must be charged in its liquid state. (If the refrigerant is
in state of gas, its composition changes and the system will not
work properly).

The connected indoor units must be indoor units designed
exclusively for R410A.

Installation

For installation of the indoor unit(s), refer to the indoor unit
installation manual.

Illustrations show class 125 outdoor unit type. Other types also
follow this installation manual.

This outdoor unit requires the pipe branching kit (optional) when
used as the outdoor unit for the simultaneous operation system.
Refer to catalogues for details.

Never operate the unit with a damaged or disconnected
discharge thermistor and suction thermistor, burning of the
compressor may result.

Be sure to confirm the model name and the serial no. of the
outer (front) plates when attaching/detaching the plates to avoid
mistakes.

When closing the service panels, take care that the tightening
torque does not exceed 4.1 N•m.

Accessories

Check if the following accessories are included with the unit

Since maximum working pressure is 4.0 MPa or 40 bar,
pipes of larger wall thickness may be required. Refer to
paragraph 

"Selection of piping material" on page 5
