Fully insulate the drain pipe inside the building (on
site).
If the drain pipe is sloped insufficiently, install the
drain pipe vertically from the hose connection port
(on site).
CAUTION
• When connecting the flexible hose to the main drain
pipe, make sure that the elbow is installed vertically.
(Horizontal installation is prohibited.)

Step 11 Connecting the power and
communication cables
1
Power and communication cable connection
• Before wiring work, you must turn off all power
source.
• Connect the power and communication cables
between the fan coil units in the electrical panel
within maximum length so that the voltage drop
is under 10%.
• Install an auxiliary circuit breaker (ELCB, MCCB,
ELB) with sufficient capacity by considering the
number of fan coil units to be connected to it.
• Connect F3 and F4 of the fan coil unit terminal
block to the communication cable of the wired
remote control.
• Tighten the electric wires with a proper tool within
the torque limit to connect and fix them firmly,
and then organize the wires to prevent outside
pressure being exerted on the covers and other
parts.
Failure to do so may result in overheating, electric
shock, and fire.
• To protect the product from water and possible
shock, you should keep the power and the
communication cables in an iron pipe.
• Connect the power cable to the auxiliary circuit
breaker (ELCB, MCCB, ELB).
• Keep a distance of 50 mm or more between the
power cable and the communication cable.
