ponent parts.
When installing the remote controller in a hospital or communication
facility, take ample countermeasures against noise.
Inverters, emergency power supply generators, high-frequency medical equip-
ment, and wireless communication equipment can cause the remote control-
ler to malfunction or to fail. Radiation from the remote controller may effect
communication equipment and prevent medial operations on the human body
or interfere with image transmission and cause noise.

3 How To Install
1. Choose a place in which to install the remote controller (switch box).
Be sure to observe the following steps:
(1) Temperature sensors are provided with both the remote controller and the indoor units. When using the
remote controller temperature sensor, the master remote controller detects the room temperature. Install
the master remote controller in a place where the average room temperature can be detected and which
is not affected by any heat source from direct sunlight or air blown from air conditioning units.
CAUTION The place where (when) the difference between the room temperature and the wall tem-
perature is large, the wall temperature that is affected by the temperature of the wall on
which the remote controller is installed is measured. Therefore, the difference between
the room temperature and the measured wall temperature may be large.
When the installation site is one of the followings, use of a temperature sensor for an
indoor unit is recommended.
- When the room is not well-ventilated and the air does not reach the wall on which the
remote controller is installed.
- When the difference between the temperature of the wall on which the remote con-
troller is installed and the room temperature.
- When the backside of the wall on which the remote controller is installed is exposed
to the outdoor air.
When the temperature changes drastically, the temperature may not be measured accu-
rately.
NOTE: Make sure that there is no wiring or wire near the remote controller sensor. If there is, the remote controller cannot detect the exact room
temperature.
2. Seal the remote controller cord with putty in order to prevent the possible entry of dew, water droplets, cockroaches, other insects, etc.
When using the switch box
• When installing on the switch box, seal
the connections between the switch box
and wiring pipe with putty.
When installing directly on the wall
When opening a hole using a drill for the remote controller cord (or when taking the cord
out of the back of the remote controller), seal the hole with putty.
• When routing the cord via the portion cut off from the upper cover, similarly seal that
portion with putty.
• When taking the remote controller cord from back of the controller, use surface race-
ways.
(3) Parts which must be supplied on site.
Switch box for two units
Thin-copper wiring pipe
Lock nut and bushing
Surface raceways
3. Remove the remote controller cover.
Insert a minus screwdriver into one of the open slots and move the screwdriver in the arrow direction.
CAUTION Do not turn the screwdriver in the slot. Doing so may damage the slot.
