33FLOOR CONSOLE INDOOR UNITINSTALLATIONFollow these key steps when selecting a location for the unit.S Select a place where cool air can be distributed throughoutthe room.S Select a place where condensation water is easily drainedaway.S Select a site that can handle the weight of the indoor unit.S Select a place which has easy access for maintenance.Indoor unitThe indoor unit should be sited in a place where:1. The restrictions for the installation specified in the indoorunit installation drawings are met.2. Both the air intake and exhaust have clear paths.3. The unit is not in the path of direct sunlight.4. The unit is away from a heat or steam source.5. There is no source of machine oil vapour (this may shortenindoor unit life).6. Cool (warm) air is circulated throughout the room.7. The unit is away from electronic ignition type fluorescentlamps (inverter or rapid stert type) as they may shorten theremote controller range.8. The unit is at least 3.28 ft. (1 m) away from any television orradio set (unit may cause interference with the picture orsound).CAUTIONS FOR INSTALLATION WHERE AIRCONDITIONER TROUBLE IS LIABLE TO OCCURS Do not install in areas with or near an abundance of oil.S Do not install in areas with an acid base area.S Do not install in areas with an irregular electrical supply.Location for securing the installation panel<0.24in/6mm7.7in/195mmFig. 63 --- Schematic Drawing of HooksREFRIGERANT PIPINGUse the following steps to connect the refrigerant pipe.1. Drill a hole (3”) in diameter) for piping and electricalrouting.2. The location of the hole is different depending on whichside of the pipe is taken out.3. For piping, see Connecting the Refrigerant Pipe, underIndoor Unit Installation (1).4. Allow space around the pipe for a easier indoor unit pipeconnection.CAUTION!The suggested shortest pipe length is 8.2 ft. (2.5 m) to avoidnoise from the outdoor unit and vibration. (Mechanicalnoise and vibration may occur depending on how the unit isinstalled and the environment in which it is used).See the installation manual for the outdoor unit for themaximum pipe length.BORING A WALL HOLE AND INSTALLING WALLEMBEDDED PIPES For walls containing metal frame or metal board ,be sure touse a wall embedded pipe and wall cover in thefeed--through hole to prevent water leakage.S Be sure to caulk the gaps around the pipes with caulkingmaterial to prevent water leakage.1. Bore a feed--through hole of 3” in the wall so it has a downslope toward the outside.2. Insert a wall pipe into the hole.3. Insert a wall cover into wall pipe.Inside OutsideCaulkingWall embedded pipe(field supply)Wall hole coverWall embedded pipe(field supply)3”Fig. 64 --- Wall Embedded Pipe4. After completing refrigerant piping, wiring, and drainpiping, caulk pipe hole gap with putty.DRAIN PIPING1. Use commercial regid polyvinyl chloride pipe general VP20 pipe, outer diameter 1 in. (26 mm), inner diameter 4/5 in.(20 mm) for the drain pipe.2. The drain hose (outer diameter 5/7 in. (18 mm) at connectingend, 8 2/3 in. (220 mm) long) is supplied with the indoor unit.Prepare the drain pipe picture below position.3. The drain pipe should be inclined downward so that waterflows smoothly without any accumulation. (Should not be atrap.)4. Insert the drain hose to this depth so it will not be pulled outof the drain pipe.5. Insulate the indoor drain pipe with insulation material toprevent condensation.6. Remove the air filters and pour some water into the drainpan to check the water flows smoothly.4 in (100 mm) Drain hose 4 in (100 mm)6 in (150 mm)Vinyl chloridedrain pipe2 in (50 mm)or moreReducerMust be no trapDo not touch waterFig. 65 --- Trap
