3-1. Selecting the Installation Site
3-1-1. Installation Conditions
Select the installation site in consultation with the client.
Select a site to install the outdoor unit that meets the following conditions:
This unit is for outdoor installation only.
The unit will not be subject to heat from other heat sources.
The noise from the unit will not be a problem.
The unit will not be exposed to strong winds.
Water from the unit can be drained properly.
The space requirements (specified on 3-1-2) are met.
1. Protection against winds
Using the figures at right as a reference,
provide adequate protection against winds.
A unit installed alone is vulnerable to strong
winds.
Select the installation site carefully to
minimize the effect of winds.
When installing a unit in a place where the
wind always blows from the same direction,
install the unit so that the outlet faces away
from the direction of the wind.
2. Cold Climate Installation
Observe the following when installing the units in areas where snow or strong winds prevail.
Avoid direct exposure to rain, winds, and snow.
Icicles that may form under the foundation can fall and inflict personal injury or property damage. Select the installation site
carefully to reduce these risks, especially when installing the unit on a roof.
If the units are installed in the direct line of rain, winds, or snow, install the optional snow hood (on both the discharge and
suction ducts). Use a snow net or snow fence as necessary to protect the unit.
Install the unit on a base approximately twice as high as the expected snowfall.
If the unit is continuously operated for a long time with the outside air temperature below the freezing point, install a heater
at the base of the unit to prevent the water from freezing at the unit bottom.
When using the unit in an outdoor temperature of -15ºC (5ºF) or below, install a drain pan (with heater whose capacity is
320 W (1100 BTU/h) or more) at the bottom surface of the unit.
