Precautions
1
All transmission wiring except for the remote controller wiring is
polarized and must match the terminal symbol.
2
In case of group control, perform the remote controller wiring to
the master unit when connecting to the simultaneous operation
system (wiring to the slave unit is unnecessary).
3
For group control remote controller, choose the remote controller
that suits the indoor unit which has the most functions (as
attached swing flap).
4
When controlling the simultaneous operation system with
2 remote controllers, connect it to the master unit (wiring to the
slave unit is unnecessary).
5
Be sure to connect the wiring to the master unit when combining
with a simultaneous operating multi-type in group control.
6
Do not ground the equipment on gas pipes, water pipes,
lightning rods or crossground with telephones. Improper ground-
ing could result in electric shock.
