Checking of limit density
Density limit is determined on the basis of the size of a room
using an indoor unit of minimum capacity. For instance, when
an indoor unit is used in a room (floor area 7.43 m
2
× ceiling
height 2.7 m = room volume 20.06 m
3
), the minimum room
volume should be 25.8 m
3
(7.738 kg ÷ 0.3 kg/m
3
) for refrigerant
of 7.738 kg (3.5 kg + 4.238 kg). Accordingly, openings such as
louvers are required for this room.
<Determination by calculation>
Overall refrigerant charge amount for the air conditioner: kg
(Minimum room volume for indoor unit: m
3
)
=
4.238 (kg) + 3.5 (kg)
= 0.39 (kg/m
3
) 0.3 (kg/m
3
)
20.06 (m
3
)
Therefore, openings such as louvers are required for this room.

2. SELECTING THE INSTALLATION SITE
2-1. Outdoor Unit
AVOID:
● heat sources, exhaust fans, etc. (Fig. 2-1)
● damp, humid or uneven locations
● indoors (no-ventilation location)
DO:
● choose a place as cool as possible.
● choose a place that is well ventilated and outside air
temperature does not exceed maximum 45°C constantly.
● allow enough room around the unit for air intake/
exhaust and possible maintenance. (Figs. 2-2, 2-3, 2-4)
● use lug bolts or equal to bolt down unit, reducing vibration
and noise.
Fig. 2-1
Installation space for outdoor unit
Install the outdoor unit with a sufficient space around the
outdoor unit for operation and maintenance.
(1) Obstructions on the left side, right side and rear side (Front
side and above the unit are opened). (Fig. 2-2)
*B
A
Fig. 2-2
* The outdoor units require necessary space to unscrew on
the rear side for maintenance and if a sufficient maintenance
space is provided on the rear side (40 cm), the space of over
15 cm is enough at the right side.
(2) Obstructions on the front side and rear side (Left side, right
side and above the unit are opened). (Fig. 2-3)
*A
B
Fig. 2-3
* For compressor replacement, 50 cm or more is required on
the front side even when using the air discharge chamber.
(3) Obstructions on the front side and above the unit (Left
side, right side and rear side are opened). (Fig. 2-4)
