7.2. Indoor unit
1. Remove two electrical wiring service panels.
2. Wire the power cable and control cable separately through the respec-
tive wiring entries given in the diagram.
•
Do not allow slackening of the terminal screws
•
Always install earch.
(Earth cable dia: Thicker than 1.6 mm)
•
Considering the case of suspending the electrical box during services,
leave the wiring some allowance. (Approx. 50 to 100 mm)
A Entry for control cable
B Clamp
C Entry for power
D Service panel for indoor controller switch setting
E Service panel for electrical wiring
F Power supply terminals. (with earth terminal)
G Indoor / Outdoor unit connecting terminals.
H Remote controller connector.
s Fix power source wiring to control box using buffer bushing for
tensile force. (PG connection or the like.)
•
Reinstall the removed parts.
•
Wire the power cable and control cable separately.
Caution:
Make electric wiring work properly with care not to allow too tight
tension.
7.3. Remote controller
1) Installing procedures
(1) Select an installing position for the remote controller (switch box).
Be sure to observe the following precautions.
1 The temperature sensors are located on both remote controller and
indoor unit. To use the temperature sensor on the remote controller,
mainly use the remote controller for temperature setting or room tem-
perature detection. Install the remote controller in such an area that
can detect average room temperatures, free of direct sunlight, airflow
from the air conditioner, and other such heating source.
2 In either case when the remote controller is installed in the switch box
or on the wall, provide the clearances indicated in the diagram. (When
the schedule timer is used in combination, also refer to the installation
manual supplied with the schedule timer.)
Note:
Check that there is no electric wire left close to the remote controller
sensor. If any electric wire is near the sensor, the remote controller
may fail to detect a correct room temperature.
3 Procure the following parts locally.
Switch box for two pieces (JIS C 8336)
Thin copper conduit tube (JIS C 8305)
Lock nuts and bushings (JIS C 8330)
A Remote controller profile
B Required clearances surrounding the remote controller
C Temperature sensor
D Installation pitch
