Toshiba RAV-SM1100UT-E Service Manual page 35

Selection of installation place
In case of continued operation of the indoor unit under
high-humidity conditions as described below, dew may
condense and water may drop.
Especially, high-humidity atmosphere (dew point
temperature : 23°C or more) may generate dew inside the
ceiling.
1. Unit is installed inside the ceiling with slated roof.
2. Unit is installed at a location using inside of the ceiling
as fresh air take-in path.
3. Kitchen
If installing a unit at such place, put insulating material
(glass wool, etc.) additionally on all the positions of the
indoor unit which come to contact with high-humidity
atmosphere.
Advice
Set a check service opening panel at right side of the unit
(size: 450 x 450mm or more) for piping, maintenance, and
servicing.
Ceiling height

When the height of the ceiling exceeds the distance of the
item Standard/4-way in Table below, the hot air is difficult to
reach the floor. Therefore, it is necessary to change the
setup value of the high ceiling switch or discharge direction.
REQUIREMENT
• When using the air conditioner with 2-way discharge
system with the standard setting (at a shipment), it
may stop abnormally in heating. Therefore, change
the setting switch according to the number of
discharge direction and the ceiling height.
• When using the air conditioner with 2-way/3-way
discharge system, a strong wind blows directly if
the ceiling height is lower than the standard.
Therefore, change the setting switch according to
height of the ceiling.
• When using the high ceiling (1) or (2) with 4-way
discharge system, the draft is apt to be felt due to
drop of the discharge temperature.
