4. Installing the refrigerant piping
4.1. Precautions for devices that use R410A refrigerant
• Refer to 1.5. for precautions not 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.
Always apply no-oxidation brazing when brazing the pipes, otherwise, the
compressor will be damaged.
(mm)
• Be sure to install the unit in a sturdy, level surface to prevent rattling noises
during peration. (Fig. 3-1)
<Foundation specifications>
Foundation bolt
Thickness of concrete
Length of bolt
Weight-bearing capacity
• Make sure that the length of the foundation bolt is within 30 mm of the bottom
surface of the base.
• Secure the base of the unit firmly with four-M10 foundation bolts in sturdy loca-
tions.
Installing the outdoor unit
• Do not block the vent. If the vent is blocked, operation will be hindered and
breakdown may result.
• 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 (ø5 ×
15 mm or less) and install on site.
• The unit must be securely installed on a structure that can sustain its
weight. If the unit is mounted on an unstable structure, it may fall down
and cause damage or injuries.
• The unit must be installed according to the instructions in order to mini-
mize the risk of damage from earthquakes, typhoons, or strong winds. An
incorrectly installed unit may fall down and cause damage or injuries.

When installing or relocating, or servicing the air conditioner, use only the
specified refrigerant (R410A) to charge the refrigerant lines. Do not mix it with
any other refrigerant and do not allow air to remain in the lines.
If air is mixed with the refrigerant, then it can be the cause of abnormal high
pressure in the refrigerant line, and may result in an explosion and other haz-
ards.
The use of any refrigerant other than that specified for the system will cause
mechanical failure or system malfunction or unit breakdown. In the worst
case, this could lead to a serious impediment to securing product safety.

• Do not use pipes thinner than those specified above.
