Precautions for R-407C 

 

 

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 5

 carefully and

follow these procedures correctly.

 

 

Since R-407C 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 R-407C.

 

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 without the thermistor (R3T), 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 Nm.

 

Handling

 

As shown in the figure, bring the unit slowly by grabbing the left and
right grips. 

Place your hands on the corner instead of holding the suction inlet in
the side of the casing, otherwise the casing could be deformed.

INSTALLATION

 

 

 

SITE

 

 

 

1

 

Select an installation site where the following conditions are
satisfied and that meets with your customer's approval.

-

Places which are well-ventilated.

-

Places where the unit does not bother next-door neighbours.

-

Safe places which can withstand the unit's weight and 
vibration and where the unit can be installed level.

-

Places where there is no possibility of flammable gas or 
product leak.

-

Places where servicing space can be well ensured.

-

Places where the indoor and outdoor units' piping and wiring 
lengths come within the allowable ranges.

-

Places where water leaking from the unit cannot cause 
damage to the location (e.g. in case of a blocked drain pipe).

-

Places where the rain can be avoided as much as possible.

 

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 a
lightning bolt.

 

 

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

 

 

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 install the air conditioner in places such as the
following:

 

 

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

 

 

Where corrosive gas, such as sulfurous 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 vapoure is present.

 

Take care not to let hands or objects come in contact with
rear fins.
