5. When connecting to an HA system.1) Remove the front grille.(6 screws, 3 front grille fixtures)2) Remove the electricalwiring box. (1 screw)3) Remove the metal plateelectrical wiring cover.(4 tabs)4) Attach the connectioncord to the S21 connectorand pull the harness outthrough the notched part in the figure.5) Replace the electrical wiring cover as it was, and pull the harness around, as shown in the figure.Indoor Unit Installation (3)6. Drain piping.1) Connect the drain hose, as described below.2) Remove the air filters and pour some waterinto the drain pan to check the water flowssmoothly.3) When drain hose requires extension, obtainan extension hose commercially available.Be sure to thermally insulate the indoorsection of the extension hose.4) When connecting a rigid polyvinyl chloride pipe(nominal diameter 1/2 inch (13mm)) directly to the drainhose attached to the indoor unit as with embeddedpiping work, use any commercially available drainsocket (nominal diameter 1/2 inch (13mm)) as a joint.1) Do not use tapped wires, stranded wires, extensioncords, or starburst connections, as they may cause overtheating,electrical shock,or fire.2) Do not use locally purchased electrical parts inside the product. (Do not branch the power for the drain pump, etc.,from the terminal block.) Doing so may cause electric shock or fire.3) When carrying out wiring connection, take care not to pull at the conduit.WARNING4. Wiring.1) As shown in the illustration on the right-hand side, insert thewires including the ground wire into the conduit and securethem with lock nut onto the conduit mounting plate.2) Insert the wires including the ground wire into J tube.3) Strip wire ends (9/16 inch (15mm)).4) Match wire colors with terminal numbers on indoor and outdoor unit’sterminal blocks and firmly screw wires to the corresponding terminals.5) Connect the ground wires to the corresponding terminals.6) Pull the wires and check that the wires are securely fixed to theterminal block.7) In case of connecting to an adapter system, run the remote controllercable and attach the S21. (Refer to 5. When connecting to an HA system.)8) Shape the wires so that the service lid fits securely, then close service lid.The drain hose shouldbe inclined downward.No trap is permitted.Do not put the endof the hose in water.Indoor unitdrain hoseφ11/16”(φ18mm)Extension drain hoseHeat insulation tube(Field supply)Drain hose supplied withthe indoor unitCommercially available drainsocket(nominal diameter 1/2 inch (13mm))Commercially available rigidpolyvinyl chloride pipe(nominal diameter 1/2 inch (13mm))φ11/16”(φ18mm)4) 5) Replace the electricalwiring cover as it was,and pull the harnessaround, as shownin the figure.Attach the connectioncord to the S21connector and pullthe harness outthrough the notchedpart in the figure.3) Remove the metal plateelectrical wiring cover.ScrewPull PullSlideTabTabSlideMetal plateelectrical coverMain bodyHA connector(S21)HA connector(S21)Lay the HA cord asshown in the figure.3211 2 3 L NWhen wire length exceeds33ft (10m), use AWG14 wires.Use AWG16 or AWG14 wirefor the Interconnecting wiresOutdoor unitIndoorunitConduit mountingplateLock nutBackConduitTerminal blockElectrical component boxUse the specified wire type.Wire retainerShape wires so that theservice lid will fit securely.TubeJ
