Complete system example (2 systems)
See figures 13 and 15
When using 1 remote controller for 1 indoor unit. (Normal
operation)
(See figure 13) .
For group control or use with 2 remote controllers (See figure 15) .
Precautions
1. A single switch can be used to supply power to units on the
same system. However, branch switches and branch circuit
breakers must be selected carefully.
2. For a group control remote controller, choose the remote
controller that suits the indoor unit which has the most functions.
3. Do not ground the equipment on gas pipes, water pipes,
lightning rods or crossground with telephones. Improper
grounding could result in electric shock.
