(2) Obstructions on the front side and rear side (Left side, right
side and above the unit are opened). (Fig. 2-3)
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)

In case of multiple installations
●
Provide a solid base (concrete block, 10 × 40 cm beams or
equal), a minimum of 15 cm above ground level to reduce
humidity and protect the unit against possible water damage
and decreased service life. (Fig. 2-5)
●
Use lug bolts or equal to bolt down unit, reducing vibration
and noise.
Fig. 2-5
2-2. Air Discharge Chamber for Top Discharge
Be sure to install the air discharge chamber in the field when:
●
it is difficult to keep a space of min. 1 m between the air
discharge outlet and an obstacle.
●
the air discharge outlet is facing a sidewalk and discharged
hot air annoys passers-by. (Fig. 2-6)

2-3. Installing the Unit in Heavy Snow Areas
In locations with strong wind, snow-proof ducting should
likewise be fitted and direct exposure to the wind should be
avoided as much as possible.
■
Countermeasures against snow and wind
In regions with snow and strong wind, the following problems
may occur when the outdoor unit is not provided with a platform
and snow-proof ducting (Fig. 2-7):
a) The outdoor fan may not run and damage of the unit may be
caused.
b) There may be no airflow.
c) The tubing may freeze and burst.
d) The condenser pressure may drop because of strong wind,
and the indoor unit may freeze.
Fig. 2-7
In regions with significant snowfall, the outdoor unit should
be provided with a platform and snow-proof duct.
2-4. Precautions for Installation in Heavy Snow
Areas
(1) The platform should be higher than the max. snow depth.
(Fig. 2-7)
(2) The 2 anchoring feet of the outdoor unit should be used for
the platform, and the platform should be installed beneath
the air intake side of outdoor unit.
(3) The platform foundation must be firm and the unit must be
secured with anchor bolts.
(4) In case of installation on a roof subject to strong wind,
countermeasures must be taken to prevent the unit from
being blown over.

3. HOW TO INSTALL THE INDOOR UNIT
■
High Static Pressure Ducted Type (E1 Type)
3-1. Required Minimum Space for Installation and
Service (8, 10 Types)
The installation instructions that come with the indoor unit
describe how to use it in combination with the U-200PE1E8 and
U-250PE1E8 outdoor units.
Please refer to the following when using it in combination
with the U-200PE1E8 and U-250PE1E8 outdoor units.
●
This air conditioner is usually installed above the ceiling so
that the indoor unit and ducts are not visible. Only the air
intake and air outlet ports are visible from below.
●
The minimum space for installation and service is shown in
Fig. 3-1.
