INSTALLING THE DUCTConnect the duct supplied in the field.Air inlet side• Attach the duct and intake-side flange (field supply).• Connect the flange to the main unit with accessory screws(in 20 or 24 positions).• Wrap the intake-side flange and duct connection area withaluminum tape or something similar to prevent air escap-ing.CAUTIONWhen attaching a duct to the intake side, be sure to attach anair filter inside the air passage on the intake side. (Use an airfilter whose dust collecting efficiency is at least 50% in agravimetric technique.)The included filter is not used when the intake duct isattached.Air outlet side• Connect the duct according to the air inside of the outlet-side flange.• Wrap the outlet-side flange and the duct connection areawith aluminum tape or something similar to prevent airescaping.CAUTION• Be sure to insulate the duct to prevent condensation fromforming. (Material: glass wool or polyethylene foam, 1 in.thick)• Use electric insulation between the duct and the wall whenusing metal ducts to pass metal laths of the net or fenceshape or metal plating into wooden buildings.• Be sure to explain how to clean local procurementssuch asair filters and grilles to your customer.9. ELECTRIC WIRING WORK9-1 GENERAL INSTRUCTIONS• Shut off the power before doing any work.• All field supplied parts and materials, electric works mustconform to local codes.• Use copper wire only.• See also the Wiring Diagram label attached to the controlbox lid when laying electrical wiring.• For details on hooking up the remote controller, refer to theREMOTE CONTROLLER INSTALLATION MANUAL.• All wiring must be performed by an authorized electrician.• This system consists of multiple indoor units. Mark eachindoor unit as unit A, unit B , and so forth, and be sure theCAUTION• The electric wiring work shall be performed by qualifiedelectricians.• If workers not having the electrician qualification have per-formed the electric wiring work, the steps 3 to 7 shall beperformed after the TEST RUN.1. Remove the lid of the control box. Connect the remotecontroller and power supply (single-phase, 60Hz 208-230V) respectively to the terminal block and securelyconnect the ground also as shown in the figure below.Securely clamp the cables with the accessory clamps(9)(10) as shown in Fig. 14 so that tension will not beapplied on the cable connection areas.2. Confirm that the lid of the control box is closed beforeturning on the power.3. Remove the inspection lid.4. Gradually pour approximately 2 quarts of water fromthe water inlet into the drain pan to check drainage.CAUTIONBe sure to prevent external force from being exerted onthe float switch or breakage can occur. Attach theinspection lid5. Perform the following operation using the remote con-troller, and check drainage.• Select the inspection/test operation button “ ”using the remote controller. The unit will engage thetest operation. Press the operation selector button“ ”, and select FAN OPERATION “ ”.• Press the ON/OFF button “ ”. The indoor fan anddrain pump will operate.CAUTIONBe cautious of the fan turning simultaneously. Do nottouch the drain pump to prevent electric shock.6. Make sure to use the remote controller in finishing theoperation.TESTTRANSMISSIONWIRINGREMOTECNTRLT1F1FORCEDOFFP2 F2P1 T2TRANSMISSIONWIRINGREMOTECNTRLT1F1FORCEDOFFP2 F2P1 T2L NL2L1Water inletPortable pumpInspection lidRefrigerant pipesBucketService drain holeDrain outlet(with rubber cap)Indoor PCboard(ASSY)Terminal blockTerminal blockRemote controllerterminal connectionmethodPower supply:Single phase,60Hz,208-230VPower terminalconnectionmethodConnection screw (7)(accessory)(Field supply)(Field supply)(Field supply)(Field supply)FlangeFlangeAluminum tapeAluminum tapeMain unitInsulationmaterialAir inlet side Air outlet side
