4• Check the pipe connector for gas leaks1 Liquid pipe2 Gas pipe3 Insulation for fitting of liquid line(supplied with the unit)4 Insulation for fitting of gas line(supplied with the unit)5 Clamps (use 2 clampsper insulation)DRAIN PIPING WORKRig the drain piping as shown in the figure and take measuresagainst condensation. Improperly rigged piping could lead toleaks and eventually wet furniture and belongings.1 Hanging bar1. Install the drain pipes.• Keep piping as short as possible and slope it downwardsso that air may not remain trapped inside the pipe.• Keep pipe size equal to or greater than that of theconnecting pipe (Vinyl pipe of 25mm nominal diameter and32mm outer diameter).• Use the supplied drain hose and metal clamp. Tighten theclamp firmly.1 Metal clamp2 Drain hose• Insulate the drain hose inside the building.• If the drain hose cannot be sufficiently set on a slope, fitthe hose with drain raising piping (field supply).HOW TO PERFORM PIPING (see figure 8)1 Ceiling slab2 Hanging bar3 Adjustable range4 Drain hose (supplied with the unit)5 Metal clamp (supplied with the unit)6 Drain raising pipe (field supply)1 Connect the drain hose to the drain raising pipes, and insulatethem.2 Connect the drain hose to the drain pipe on the indoor unit,and tighten it with the metal clamp.Installation ARear suction installation 275When canvas duct is installed 350-530When air inlet panel is directly installed 275• To ensure a downward slope of 1:100, install hanging barsevery 1 to 1.5m.• If unifying multiple drain pipes, install the pipes as shownin figure 9.1 Multiple drain piping2. After piping work is finished, check if drainage flowssmoothly.• Open the water inlet lid, add approximately 1l of watergradually and check the drainage flow (see figure 10).1 Water inlet2 Portable pump3 Water inlet lid4 Bucket (adding water from water inlet)5 Drain outlet for maintenance (with rubber drain plug)6 Refrigerant pipesNOTEThe drain outlet is only used to discharge water if the drain pumpis not used or before maintenance. Gently put in and out thedrain plug. Excessive force may deform the drain socket of thedrain pan.WHEN ELECTRIC WIRING WORK IS FINISHEDCheck drainage flow during COOL running, explained in chapter"TEST OPERATION".WHEN ELECTRIC WIRING WORK IS NOT FINISHED• Remove the switch box cover and connect the single-phasepower supply and the remote controller to the terminals.(Refer to chapter "ELECTRIC WIRING WORK" for switch boxattachment/detachment) (Refer to figure 11a and 11b)1 Switch box cover2 Power supply wiring port3 Transmission wiring port4 Wiring diagram5 Switch box6 Plastic clamp7 Remote controller wiring8 Terminal board for unit transmission wiring9 Power supply wiring10 Emergency switch11 Power supply terminal board12 Earth screw• Remove the switch box cover and change the emergencyswitch on the PC board of the indoor unit from "NORMAL" to"EMERGENCY". Be sure to change the switch to"EMERGENCY" before turning on the power.• Connect the single-phase power supply (50Hz; 230V) toconnections 1 and 3 (see figure below) on the power supplyterminal board and confirm drain operation.• Be aware that the fan will turn during the operation.• After confirming drainage, turn off the power and be sure tochange the emergency switch back to "NORMAL".ELECTRIC WIRING WORKGeneral instructions• All field supplied parts and materials and electric works mustconform to local codes.• Use copper wire only.• Follow the "Wiring diagram" attached to the switch box coverto wire the outdoor unit, indoor units and the remotecontroller. For details on hooking up the remote controller,refer to the "Installation manual of the remote controller".• All wiring must be performed by an authorized electrician.• A circuit breaker capable of shutting down power supply to theentire system must be installed.2111-1.5m1 2 353124
