Installation EDUS30-900-N
34 Installation of Outdoor Units
2-6 Electrical specifications
3. SELECTION OF LOCATION
This unit does not have specifications for outdoor installation.
The unit must be installed indoors (example: machine room, …).
Paying attention to the conditions mentioned below, select the place
for installation with a prior approval of customer.
1.
The foundation is strong enough to support the weight of the unit
and the floor is flat to prevent vibration and noise generation.
2.
Consider the space required for refrigerant piping work when
installing. Refer to [Necessary Space].
3.
There is no danger of fire due to leakage of inflammable gas.
4.
The piping length between the outside unit and the indoor unit may
not exceed the allowable piping length. “
9. REFRIGERANT PIP-
ING
”.
5.
Locations where the noise of the unit operating will not disturb
nearby houses, etc.
6.
Locations with airflow and ventilation holes capable of dissipating
heat from the machine and where the ambient temperature around
the outside unit is between 35 and 95 °F and the humidity does not
exceed 80%.
7.
Consider condensate drain of condenser unit.
[Necessary Space]
When installing, secure the space mentioned below without fail.
(Refer to figure 2)
1.
In case of a single installation [inch.]
2.
In case of series installations [inch.]

Space for installing water piping

Secure a enough space for removing the front panel.
9.
Ventilation Space

above the area ( ) of the outside unit.
10.
Secure spaces in the front, back and top sides as same
as the case of single installation.
DANGER
•
Do not install unit in an area where flammable materials are
present due to risk of explosion resulting in serious injury or
death.
•
Refrigerant is heavier than air and replaces oxygen. A massive leak
could lead to oxygen depletion, especially in basements, and an
asphyxiation hazard could occur leading to serious injury or death.
Refer to the chapter “Caution for refrigerant leaks”.
NOTE
1.
An inverter air conditioner may cause electronic noise gener-
ated from AM broadcasting. Examine where to install the main
air conditioner and electric wires, keeping proper distances
away from stereo equipment, personal computers, etc.
(Refer to figure 3)

Indoor unit
2.
Branch switch, overcurrent breaker
3.
Remote controller
4.
Cool/heat selector
5.
Personal computer or radio
If the electric wave of AM broadcasting is particularly weak, keep
distances of 10 ft or more and use conduit tubes for power and
transmission lines.
2.
Water quality
Water containing high level of foreign materials may cause the
corrosion of heat exchanger and piping or scale accumulation.
Use water satisfying “7-4 Water quality”.
3.
Cooling tower
Use a closed type cooling tower without fail. (Open type tower
cannot be used.)
