1) Installing procedures
(1) Select an installing position for the remote controller. (Fig. 6-7)
The temperature sensors are located on both remote controller and indoor unit.
s
Procure the following parts locally:
Two piece switch box
Thin copper conduit tube
Lock nuts and bushings

Remote controller profile
B
Required clearances surrounding the remote controller
C
Installation pitch
(2) Seal the service entrance for the remote controller cord with putty to prevent pos-
sible invasion of dew drops, water, cockroaches or worms. (Fig. 6-8)

For direct installation on the wall select one of the following:
• Prepare a hole through the wall to pass the remote controller cord (in order to run
the remote controller cord from the back), then seal the hole with putty.
• Run the remote controller cord through the cut-out upper case, then seal the cut-

7.1. Before test run
s
After completing installation and the wiring and piping of the indoor and
outdoor units, check for refrigerant leakage, looseness in the power supply
or control wiring, wrong polarity, and no disconnection of one phase in the
supply.
s
Use a 500-volt megohmmeter to check that the resistance between the power
supply terminals and ground is at least 1.0 M
Ω Ω Ω Ω Ω
.
s Do not carry out this test on the control wiring (low voltage circuit) termi-
nals.
Warning:
Do not use the air conditioner if the insulation resistance is less than 1.0 M
Ω Ω Ω Ω Ω
.

does not operate properly, refer to the outdoor unit installation manual or
other technical materials.
• The OFF timer is set for the test run to automatically stop after 2 hours.
• During the test run, the time remaining is shown in the time display.
• During the test run, the temperature of the indoor unit refrigerant pipes is
shown in the room temperature display of the remote controller.
• When the VANE or LOUVER button is pressed, the message “NOT AVAIL-
ABLE” may appear on the remote controller display depending on the indoor
unit model, but this is not a malfunction.
