3.4. Transporting the unit

Do not touch the fins.
Otherwise, personal injury could result.
When carrying the unit, hold the handles on the right and left sides and be careful.
If the outdoor unit is carried from the bottom, hands or fingers may be pinched.
• Carry slowly in the manner as shown on "Fig. B" holding the handles "Fig. A" in right
and left sides. (Be careful not to touch with hands or objects.)
• Be sure to hold the handles on the sides of the unit. Otherwise, the suction grilles on
the sides of the unit may be deformed.

• Install 4 anchor bolts at the locations indicated with arrows in the above figure.
• To reduce vibration, do not install the unit directly on the ground. Install it on a secure
base (such as concrete blocks).

• The foundation shall support the legs of the unit and have a width of 50 mm or more.
• Depending on the installation conditions, the outdoor unit may spread its vibration
during operation, which may cause noise and vibration. Therefore, attach damping
materials (such as damping pads) to the outdoor unit during installation.
• Install the foundation, making sure that there is enough space for installing the
connection pipes.
• Secure the unit to a solid block using foundation bolts. (Use 4 sets of commercially
available M10 bolts, nuts, and washers.)
• The bolts should protrude 20 mm.
(Refer to the figure below.)
• If overturning prevention is required, purchase the necessary commercially available
items.
Fix securely with bolts on a solid block. (Use 4 sets of commercially available M10 bolt,
nut and washer.)

4. PIPE SELECTION

4.1. Selecting the pipe material

Do not use existing pipes.
Use pipes that have clean external and internal sides without any contamination which
may cause trouble during use, such as sulfur, oxide, dust, cutting waste, oil, or water.
It is necessary to use seamless copper pipes.
Material: Phosphor deoxidized seamless copper pipes.
It is desirable that the amount of residual oil is less than 40 mg/10 m.
Do not use copper pipes that have a collapsed, deformed, or discolored portion
(especially on the interior surface). Otherwise, the expansion valve or capillary tube may
become blocked with contaminants.
Improper pipe selection will degrade performance. As an air conditioner using R410A
incurs pressure higher than when using conventional refrigerant, it is necessary to
choose adequate materials.
Note:
Thicknesses of copper pipes used with R410A are as shown in the table.
Never use copper pipes thinner than those indicated in the table even if they are available
on the market.

6.35 (1/4)
9.52 (3/8)
12.70 (1/2)
15.88 (5/8)
19.05 (3/4)

4.2. Protection of pipes

Protect the pipes to prevent the entry of moisture and dust.
Especially, pay attention when passing the pipes through a hole or connecting the end of
a pipe to the outdoor unit.
