at the front of the farthest indoorunit fromthe main
drain pipe.
• To preventwaterfromflowing backto indoorunits,install
anindividualairvent atthe topof eachindoorunit.
– The airvents should be Tor7 shaped to prevent
dust orforeign substances from entering.
– You may not need to install airvent if the horizontal
drain pipe is in properslope.

CAUTION
• When the float switch is not detected due to
insufficientwateron the drain pan, the drain
pumpwill not work.
• If the powersupplyis directlyconnected to the L
and N terminals, communication errormessage
might appear.
• Aftercompleting the drainage check, turn the unit
off and disconnect the powersupply.
• Reassemble the control box cover.
c Checkwhetherthe drain pumpworks correctly.
d Checkwhetherthe drainage is performing
correctlyat the end of the drain pipe.
e Check forleakage at the drain pipe and drain pipe
connection part.
f When leakage occurs, checkwhetherthe 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 condensedwaterremains on the drain pan,
remove thewater.
Step12 Connectingthepowerand
communicationcables
Powerand communication cableconnection
• Before wiringwork,you must turn off all powersource.
• Connectthe powerand communication cable among
the unitswithin maximum length to set thevoltage
drop under10%.
• The auxiliary circuit breaker(ELCB, MCCB, ELB) should
be considered more capacityif many indoorunits are
connected from one breaker.
• Connect F3, F4(forcommunication) to the
communication cable of the wired remote control.
• Tighten the electricwireswith a propertoolwithin the
torque limit to connect and fix them firmly, and then
organize thewires to prevent outside pressure being
exerted on the covers and otherparts. Failure to do so
mayresult in overheating, electric shock, and fire.
Tighteningtorque(N•m)
M3.5 0.8 ~1.2
M4 1.2 ~1.8
(1 N•m =10 kgf•cm)
• To protect the product fromwaterand possible shock,
you should keep the powerand the communication
cables ofthe indoorand outdoorunits in the iron pipe.
• Connectthe powercableto the auxiliary circuit
breaker(ELCB, MCCB, ELB).
• Keep distances of 50mm ormore between powercable
and communication cables.
• Powersupplycords of parts of appliances foroutdoor
use shall not be lighterthan polychloroprene sheathed
flexible cord. (Code designation IEC:60245 IEC 57 /
CENELEC: H05RN-F orIEC:60245 IEC 66 / CENELEC:
H07RN-F)
• Screws on terminal block must not be unscrewed with
the torque less than12 kgf•cm.
• When installing the indoorunit in a computerroom,
use the double shielded (tape aluminum / polyester
braid + copper) cable of FROHH2R type.
