(3) Clamp the tubing bundle to the wall, using 1 clamp approx.
each meter.
Insulated tubes
NOTE
Do not wind the armoring tape too tightly since this will
decrease the heat insulation effect. Also ensure that the
condensation drain hose splits away from the bundle and drips
clear of the unit and the tubing.
5-5. Finishing the Installation
After finishing insulating and taping over the tubing, use sealing
putty to seal off the hole in the wall to prevent rain and draft
from entering.

8. PRECAUTIONS ON TEST RUN
Request that the customer be present when the test run is
●
performed. At this time, explain the operation manual and
have the customer perform the actual steps.
Check that the 220 – 240 V AC power is not connected to
●
the inter-unit control wiring connector terminal.
* If 220 – 240 V AC is accidentally applied, the indoor unit
control PCB fuse will blow in order to protect the PCB.
In this case, make the wiring correctly. Then reconnect the
connector to pins 2 and 3 from pins 1 and 2 on the 3P DIP
pin (EMG).
If the operation is not activated even if the short circuit pin
is reconnected, cut the jumper on the indoor unit PCB.
(Be sure to turn the power OFF before performing this
work.)
