2. Selecting an installation site
2.1. Installation site
•
Place not exposed to rain (BC controller is a special machine for
indoor use.)
•
Place with large enough service space
•
Place in which refrigerant pipes can be provided within the limita-
tions
•
Place not exposed to direct radiant heat from other heat sources
•
Do not install the unit in any oily steamy place or near any machine
that generates high frequencies. Doing so may cause a risk of fire,
erroneous operation or dew drop.
•
Place with less noise effect generated from other units
•
Place in which water piping, refrigerant piping and electrical wiring
can be done easily
•
Avoid places exposed to the generation, inflow, accumulation or leak-
age of flammable and sulfuric gases
•
Place in which a downward pitch of more than 1/100 can be taken for
drain piping
1. For hanging from the ceiling
•
Provide a inspection hole 450 mm square to the ceiling surface as
shown in 2.2.1 1.
•
Above the ceiling of corridor, bath room, etc., where persons are not
regularly there
(Avoid installing at around center of the room.)
•
Place with strength to the degree that hanging bolts can be mounted
(that sustains a pull-out load of 60kg per bolt)
•
Be sure to install BC controllers at level.
2. For stacking on a rack
•
Place in which sufficient space can be obtained around a rack
•
Place with floor strength that sustains the entire weight
Warning:
Be sure to install the unit in a place that well sustains the entire
weight.
If there is a lack of strength, it may cause the unit to fall down,
resulting in an injury.
Caution:
Be sure to install the unit at level.
