〈Methods of wiring power supply, units and connecting

〉
• Power supply wire
Remove the control box lid (2) and connect wires to the
power supply terminal block (3P) inside. In doing this, pull the
wires inside through rubber bush A and clamp the wires
along with other wires using clamp A, untightening the clip of
clamp A by pressing. After the connection, tighten clamp A
as before.
• Transmission wire and remote controller wire
Remove the control box lid (1) and pull the wires inside
through rubber bush B and connect to the transmission ter-
minal block (6P).
• After connection, attach sealing pad
(Be sure to attach it to prevent water from infiltrating the unit
from the outside.)
CAUTION
• Even if the control box lid (1)(2) is removed, pull the remote
controller wire, transmission wire and the power supply wire
inside the unit so that the wires do not come into contact with
the opening section of the metal casing.
• Pass conduits through the wall and secure along with the
refrigerant pipe in order to prevent external pressure being
applied to transmission wire and power supply wire.
• Arrange the wires and fix a lid firmly so that the lid does not
float during wiring work.
• Do not clamp remote controller wire and transmission wire
together with power supply wire. Doing so may cause mal-
function.
• Remote controller wire, transmission wire and power supply
wire should be located at least 5 in. from other electric wires.
Not following this guideline may result in malfunction due to
electrical noise.
