1.3. Before getting installed (moved) - elec-
trical work
Caution:
• Ground the unit.
- Do not connect the ground wire to gas or water pipes, lightning rods, or
telephone ground lines. Improper grounding may result in electric shock.
• Install the power cable so that tension is not applied to the cable.
- Tension may cause the cable to break and generate heat and cause a fire.
• Install an leak circuit breaker, as required.
- If an leak circuit breaker is not installed, electric shock may result.
• Use power line cables of sufficient current carrying capacity and rating.
- Cables that are too small may leak, generate heat, and cause a fire.
• Use only a circuit breaker and fuse of the specified capacity.
- A fuse or circuit breaker of a larger capacity or a steel or copper wire may
result in a general unit failure or fire.
• Do not wash the air conditioner units.
- Washing them may cause an electric shock.
• Be careful that the installation base is not damaged by long use.
- If the damage is left uncorrected, the unit may fall and cause personal injury
or property damage.
• Install the drain piping according to this Installation Manual to ensure
proper drainage. Wrap thermal insulation around the pipes to prevent
condensation.
- Improper drain piping may cause water leakage and damage to furniture
and other possessions.
• Be very careful about product transportation.
- Only one person should not carry the product if it weighs more than 20 kg.
- Some products use PP bands for packaging. Do not use any PP bands for a
means of transportation. It is dangerous.

(1) Basic space required
A space of at least 250 [9-27/32] is necessary at the back for inlet air. Taking
servicing, etc. from the rear into account, a space of about 450 [17-23/32] should
be provided, the same as at the front. (Unit: mm [in])
(2) When there is an obstruction above the unit
(3) When inlet air enters from right and left sides of unit
• Wall heights (H) of the front and the back sides shall be within overall height of
unit.
• When the total height is exceeded, add the "h" dimension of the Fig. 4.0.1 to L
and L .

- Do not touch the heat exchanger fins. Doing so may cut your fingers.
- When transporting the outdoor unit, suspend it at the specified positions on
the unit base. Also support the outdoor unit at four points so that it cannot
slip sideways.
• Safely dispose of the packing materials.
- Packing materials, such as nails and other metal or wooden parts, may cause
stabs or other injuries.
- Tear apart and throw away plastic packaging bags so that children will not
play with them. If children play with a plastic bag which was not torn apart,
they face the risk of suffocation.

1.4. Before starting the test run

Caution:
• Turn on the power at least 12 hours before starting operation.
- Starting operation immediately after turning on the main power switch can
result ibésevere damage to internal parts. Keep the power switch turned on
during the operational season.
• Do not touch the switches with wet fingers.
- Touching a switch with wet fingers can cause electric shock.
• Do not touch the refrigerant pipes during and immediately after opera-
tion.
- During and immediately after operation, the refrigerant pipes are may be hot
and may be cold, depending on the condition of the refrigerant flowing through
the refrigerant piping, compressor, and other refrigerant cycle parts. Your
hands may suffer burns or frostbite if you touch the refrigerant pipes.
• Do not operate the air conditioner with the panels and guards removed.
- Rotating, hot, or high-voltage parts can cause injuries.
• Do not turn off the power immediately after stopping operation.
- Always wait at least five minutes before turning off the power. Otherwise,
water leakage and trouble may occur.

(4) When unit is surrounded by walls
Note:
• Wall heights (H) of the front and the back sides shall be within overall
height of unit.
• If the panel height is exceeded, add the "h" dimension of the Fig. 4.0.1 to
L and L .

Example: When h is 100 [3-15/16],
the L dimension becomes 450 [17-23/32] + 100 [3-15/16]
1
= 550 [21-21/32].
(5) Collective installation and continuous installation
• Space required for collective installation and continuous installation:
When installing several units, leave the space between each block considering
passage for air and people.
• Open in the two directions.
• In case wall height (H) exceeds overall height of unit, add "h" dimension (h =
wall height <H> – overall height of unit) to * marked dimension.
• If there is a wall at both the front and the rear of the unit, install up to four units
consecutively in the side direction and provide a space of 1000 [39-3/8] or
more as inlet space/passage space for each four units. (Unit: mm [in])
