3.1.8 Electric wiring work
1) General instructions
①
All field supplied parts and materials, electric works must
conform to local codes.
Use copper wire only.
②
Follow the "WIRING DIAGRAM” attached to the unit
body to wire the outdoor unit, indoor units and the remote
controller.
③
All wiring must be performed by an authorized electri-
cian.
④
This system consists of multiple indoor units. Mark each
indoor unit as unit A, unit B..., and be sure the terminal
board wiring to the outdoor unit and indoor units are
properly matched. If wiring and piping between the out-
door unit and an indoor units are mismatched, the sys-
tem may cause a malfunction.
⑤
A circuit breaker capable of shutting down the power
supply to the entire system must be installed.
2) Wiring Connection
①
Open the control box cover and connect the Remote
controller cord and Indoor power wires.
②
Make sure to attach the sealing material (field supplied)
to hole of wiring to prevent the infiltration of foreign parti-
cle from outside. Otherwise a short-circuit may occur
inside the electric parts box
③
When clamping the wires, be sure no pressure is applied
to the wire connections by using the included clamping
material to make appropriate clamps. Also, when wiring,
make sure the cover on the electric parts box fits snugly
by arranging the wires neatly and attaching the electric
parts box cover firmly. When attaching the electric parts
box cover, make sure no wires get caught in the edges.
Pass wiring through the holes to prevent damage to
them.
④
Make sure the remote controller wiring, the wiring
between the units, and other electrical wiring do not pass
through the same locations outside of the unit, separat-
ing them properly, otherwise electrical noise (external
static) could cause product malfunction.
