• Be sure to install the unit in a sturdy, level surface to prevent rattling noises during
(mm) operation. (Fig. 3-1)
A <Foundation specifications>
Foundation bolt M10 (3/8")
Thickness of concrete 120 mm
Length of bolt 70 mm

• Make sure that the length of the foundation bolt is within 30 mm of the bottom
C surface of the base.
Max. 30 for RP60-140

• Secure the base of the unit firmly with four-M10 foundation bolts in sturdy locations.

D • In addition to the unit base, use the installation holes on the back of the unit to attach
wires, etc., if necessary to install the unit. Use self-tapping screws ([5 o 15 mm or
more) and install on site.

Warning:

4. Installing the refrigerant piping

4.1. Precautions for devices that use R410A refrigerant
• Use ester oil, ether oil, alkylbenzene oil (small amount) as the refrigeration oil
applied to the flared sections.
• Use C1220 copper phosphorus, for copper and copper alloy seamless pipes,
to connect the refrigerant pipes. Use refrigerant pipes with the thicknesses
specified in the table to the below. Make sure the insides of the pipes are
clean and do not contain any harmful contaminants such as sulfuric com-
pounds, oxidants, debris, or dust.

Warning:
When installing or moving the air conditioner, use only the specified refriger-
ant (R410A) to charge the refrigerant lines. Do not mix it with any other refriger-
ant and do not allow air to remain in the lines. Air enclosed in the lines can
cause pressure peaks resulting in a rupture and other hazards.

• Avoid locations where combustible gases may leak, be produced, flow, or accumulate.
• Note that water may drain from the unit during operation.
• Select a level location that can bear the weight and vibration of the unit.
• Avoid locations where the unit can be covered by snow. In areas where heavy snow
fall is anticipated, special precautions such as raising the installation location or
installing a hood on the air intake and air outlet must be taken to prevent the snow
from blocking the air intake or blowing directly against it. This can reduce the airflow

• When hang-lifting the unit, pass the sling or rope through the square-shaped holes
at the base and through the lifting hooks at the front and rear of the top.
• Always pass the sling or rope through the four lifting hooks on the top of the unit.
Use care not to jolt or expose the unit to impact.
• Make sure that the lifting angle of the rope or sling is 40° or less.
• Use two slings or ropes for lifting. Make sure that the rope or sling is 7 meters long
or longer and can withstand the weight of the unit.
• Place some form of padding between the unit and the rope or sling passing through
the square-shape openings to prevent scratching or damaging the unit.

Caution:
Precautions When Transporting
• Units weighing 20 kg or more shall not be lifted by one person.
• Never touch the finned surface of the heat exchanger with your bare hands.
This area can cause cuts or damage.
• Never allow children to play with the plastic bag used for covering the unit.
Asphyxiation could occur. Always cut up the bag before disposing.
• Always use the designated spaces provided at the base of the unit when
lifting the unit. Make sure that four support points are always used. The unit
will be unstable and tip over or be dropped if lifted or transported using less
than four support points.

5. Installing the refrigerant piping

5.1. Precautions for devices that use R410A refrigerant
• Use ester oil, ether oil, alkylbenzene oil (small amount) as the refrigeration oil
applied to the flared sections.
• Use C1220 copper phosphorus, for copper and copper alloy seamless pipes,
to connect the refrigerant pipes. Use refrigerant pipes with the thicknesses
specified in the table to the below. Make sure the insides of the pipes are
clean and do not contain any harmful contaminants such as sulfuric com-
pounds, oxidants, debris, or dust.
• Always use a non-oxidizing brazing material when brazing the pipes. The com-
pressor will be damaged if this type of brazing material is not used.

Warning:
When installing or moving the air conditioner, use only the specified refriger-
ant (R410A) to charge the refrigerant lines. Do not mix it with any other refriger-
ant and do not allow air to remain in the lines. Air enclosed in the lines can
cause pressure peaks resulting in a rupture and other hazards.

prevent refrigerant leakage.

• Avoid locations where the unit can be covered by snow. In areas where heavy snow
fall is anticipated, special precautions such as raising the installation location or
installing a hood on the air intake must be taken to prevent the snow from blocking
the air intake or blowing directly against it. This can reduce the airflow and a mal-
function may result.

4. Installing the refrigerant piping

4.1. Precautions for devices that use R410A refrigerant
• Use ester oil, ether oil, alkylbenzene oil (small amount) as the refrigeration oil
applied to the flared sections.
• Use C1220 copper phosphorus, for copper and copper alloy seamless pipes,
to connect the refrigerant pipes. Use refrigerant pipes with the thicknesses
specified in the table to the below. Make sure the insides of the pipes are
clean and do not contain any harmful contaminants such as sulfuric com-
pounds, oxidants, debris, or dust.

Warning:
When installing or moving the air conditioner, use only the specified refriger-
ant (R410A) to charge the refrigerant lines. Do not mix it with any other refriger-
ant and do not allow air to remain in the lines. Air enclosed in the lines can
cause pressure peaks resulting in a rupture and other hazards.

• Note that water may drain from the unit during operation.
• Select a level location that can bear the weight and vibration of the unit.
• Avoid locations where the unit can be covered by snow. In areas where heavy snow
fall is anticipated, special precautions such as raising the installation location or
installing a hood on the air intake must be taken to prevent the snow from blocking
the air intake or blowing directly against it. This can reduce the airflow and a mal-
function may result.

4. Installing the refrigerant piping

4.1. Precautions for devices that use R410A refrigerant
• Refer to "Safty precautions" included below on using air conditioners with
R410A refrigerant.
• Use ester oil, ether oil, alkylbenzene oil (small amount) as the refrigeration oil
applied to the flared sections.
• Use C1220 copper phosphorus, for copper and copper alloy seamless pipes,
to connect the refrigerant pipes. Use refrigerant pipes with the thicknesses
specified in the table to the below. Make sure the insides of the pipes are
clean and do not contain any harmful contaminants such as sulfuric com-
pounds, oxidants, debris, or dust.

Warning:
When installing or moving the air conditioner, use only the specified refriger-
ant (R410A) to charge the refrigerant lines. Do not mix it with any other refriger-
ant and do not allow air to remain in the lines. Air enclosed in the lines can
cause pressure peaks resulting in a rupture and other hazards.

INSTALLATION PROCEDURE

Caution:
Be very careful to carry product.
- Do not have only one person to carry product if it is more than 20 kg.
- PP bands are used to pack some products. Do not use them as a mean for transportation because they are dangerous.
- Do not touch heat exchanger fins with your bare hands. Otherwise you may get a cut in your hands.
- Tear plastic packaging bag and scrap it so that children cannot play with it. Otherwise plastic packaging bag may suffocate children to death.
- When carrying in outdoor unit, be sure to support it at four points. Carrying in and lifting with 3-point support may make outdoor unit unstable, resulting in a fall of it.

7. Refrigerant piping installation

Flare connection must be applied to the indoor unit and liquid piping of the outdoor
unit, whilst flange connection must be applied to the gas piping of the outdoor unit.

3 Use care to prevent dust, water or other contaminants from entering the piping
during installation.
4 Reduce the number of bending portions as much as possible, and make bend-
ing radius as big as possible.
5 Always observe the restrictions on the refrigerant piping (such as rated length,
the difference between high/low pressures, and piping diameter). Failure to do
so can result in equipment failure or a decline in heating/cooling performance.
