5. Selection of installation site
Select space for installing outdoor unit, which will meet the following
conditions:
• no direct thermal radiation from other heat sources
• no possibility of annoying neighbors by noise from unit
• no exposition to strong wind
• with strength which bears weight of unit
• note that drain flows out of unit when heating
• with space for air passage and service work shown below
Because of the possibility of fire, do not install unit to the space where
generation, inflow, stagnation, and leak of combustible gas is ex-
pected.
• Avoid unit installation in a place where acidic solution and spray (sulfur)
are often used.
• When having cooling operation at an outside air temperature of be-
low 10°C, in order to obtain steady operation of unit, select an instal-
lation site not exposed directly to rain and snow, or install air outlet
and inlet ducts. (Refer to Page
11
.) Install the outdoor unit at the
same position on the same floor, or above, the indoor unit. (See the
figure at the right.)
• Do not use unit in any special environment where oil, steam and
sulfuric gas exist.
Installation restriction on outdoor unit when cooling operation is performed
when the outdoor air temperature is 10°C or lower
