Selection Of Installation Location - Mitsubishi Heavy Industries SRK20ZJX-S Service Manual

• Do not install the unit near the location where leakage
of combustible gases can occur.
If leaked gases accumulate around the unit, it can cause
fire.
• Do not install the unit where corrosive gas (such as
sulfurous acid gas etc.) or combustible gas (such as
thinner and petroleum gases) can accumulate or
collect, or where volatile combustible substances are
handled.
Corrosive gas can cause corrosion of heat exchanger,
breakage of plastic parts and etc. And combustible gas can
cause fire.
• Do not install nor use the system close to the
equipment that generates electromagnetic fields or
high frequency harmonics.
Equipment such as inverters, standby generators, medical
high frequency equipments and telecommunication
equipments can affect the system, and cause malfunctions
Check before installation work
• Model name and power source
• Refrigerant piping length
• Piping, wiring and miscellaneous small parts
• Indoor unit installation manual

Where the following installation space is available, and where air does not gather.
Where rain and sunlight do not directly hit the unit, and where there is enough air circulation.
Also, where the unit cannot be buried by snow.
a location which can sustain the weight of the unit, and where noises and vibrations are not
enhanced.
Where blasts of cold or hot air and noise do not bother the neighbors.
Where the unit does not receive heat radiation from other heat sources.
Where there are no obstructions (animals, plants, etc.) to the suction inlet and blowing outlet.
Where water may drain out.
