  CAUTION

•  When the float switch is not detected due to 

insufficient water on the drain pan, the drain 
pump will not work.

•  If the power supply is directly connected to the L 

and N terminals, communication error message 
might appear.

•  After completing the drainage check, turn the unit 

off and disconnect the power supply.

•  Reassemble the control box cover.

c 

Check whether the drain pump works correctly.

d 

Check whether the drainage is performing 
correctly at the end of the drain pipe.

e 

Check for leakage at the drain pipe and drain pipe 
connection part.

f 

When leakage occurs, check whether the indoor 
unit is level and check the drain hose connection 
part, drainpipe connection part and drain pump 
connection.

g 

When the drainage check is completed and 
the condensed water remains on the drain pan, 
remove the water.

Step 12  Connecting the power and 

communication cables

Power and communication cable connection

•  Before wiring work, you must turn off all power source.
•  Connect the power and communication cable among 

the units within maximum length to set the voltage 
drop under 10%.

•  The auxiliary circuit breaker (ELCB, MCCB, ELB) should 

be considered more capacity if many indoor units are 
connected from one breaker. 

•  Connect F3, F4(for communication) 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.

Tightening torque (N•m)

0.8 ~ 1.2

M4

1.2 ~ 1.8

(1 N•m = 10 kgf•cm)

•  To protect the product from water and possible shock, 

you should keep the power and the communication 
cables of the indoor and outdoor units in the iron pipe.

•  Connect the power cable to the auxiliary circuit 

breaker (ELCB, MCCB, ELB).

•  Keep distances of 50mm or more between power cable 

and communication cables.

•  Power supply cords of parts of appliances for outdoor 

use shall not be lighter than polychloroprene sheathed 
flexible cord. (Code designation IEC:60245 IEC 57 / 
CENELEC: H05RN-F or IEC:60245 IEC 66 / CENELEC: 
H07RN-F)

•  Screws on terminal block must not be unscrewed with 

the torque less than 12 kgf•cm.

•  When installing the indoor unit in a computer room, 

use the double shielded (tape aluminum / polyester 
braid + copper) cable of FROHH2R type.
