FFQ25~60C2VEBSplit System air conditioners4P341094-1B – 2013.04Installation manual2For the following items, take special care duringconstruction and check after installation is finishedNotes to the installer Read this manual carefully to ensure correct installation. Be sureto instruct the customer how to properly operate the system andshow him/her the enclosed operation manual. Explain to the customer what system is installed on the site. Besure to fill out the appropriate installation specifications in thechapter "What to do before operation" of the outdoor unitoperation manual.Selecting installation siteWhen the conditions in the ceiling are exceeding 30°C and a relativehumidity of 80%, or when fresh air is inducted into the ceiling, anadditional insulation is required (minimum 10 mm thickness,polyethylene foam).For this unit you can select different air flow directions. It is necessaryto purchase an optional blocking pad kit to discharge the air in 3 or4 (closed corners) directions.Install the unit so that air vents, lights, or machines near the unit donot interfere with the air flow.1 Select an installation site where the following conditions arefulfilled and that meets your customer's approval.• Where optimum air distribution can be ensured.• Where nothing blocks air passage.• Where condensate water can be properly drained.• Where the false ceiling is not noticeably on an incline.• Where sufficient clearance for maintenance and service can beensured.• Where there is no risk of flammable gas leaking.• The equipment is not intended for use in a potentially explosiveatmosphere.• Where piping between indoor and outdoor units is possible within theallowable limit. (Refer to the installation manual of the outdoor unit.)• Keep indoor unit, outdoor unit, inter unit wiring and remotecontroller wiring at least 1 meter away from televisions andradios. This is to prevent image interference and noise in thoseelectrical appliances. (Noise may be generated depending on theconditions under which the electric wave is generated, even if1 meter is kept.)• When installing the wireless remote controller kit, the distancebetween wireless remote controller and indoor unit might beshorter if there are fluorescent lights who are electrically startedin the room. The indoor unit must be installed as far as possibleaway from fluorescent lights.2 Ceiling heightThis indoor unit may be installed on ceilings up to 3.5 m inheight. However, it becomes necessary to make field settingsusing the remote controller when installing the unit at a heightover 2.7 m.To avoid accidental touching, it is recommended to install theunit higher than 2.5 m.Refer to "Field setting" on page 8 and to the decoration panelinstallation manual.3 Air flow directionsSelect the air flow directions best suited to the room and point ofinstallation. (For air discharge in 3 directions, it is necessary tomake field settings by means of the remote controller and toclose the air outlet(s). Refer to the installation manual of theoptional blocking pad kit and to "Field setting" on page 8. (Seefigure 1) ( : air flow direction)4 Use suspension bolts for installation. Check whether the ceilingis strong enough to support the weight of the indoor unit. If thereis a risk, reinforce the ceiling before installing the unit.(The installation pitch is marked on the paper pattern forinstallation. Refer to it to check for points requiring reinforcing.)Space required for installation see figure 2 ( : air flowdirection)Tick whenchecked Is the indoor unit fixed firmly?The unit may drop, vibrate or make noise. Is the gas leak test finished?It may result in insufficient cooling or heating. Is the unit fully insulated?Condensate water may drip. Does drainage flow smoothly?Condensate water may drip. Does the power supply voltage correspond to that shown on thename plate?The unit may malfunction or components may burn out. Are wiring and piping correct?The unit may malfunction or components may burn out. Is the unit safely grounded?Dangerous at electric leakage. Is the wiring size according to specifications?The unit may malfunction or components may burn out. Is nothing blocking the air outlet or inlet of either the indoor oroutdoor units?It may result in insufficient cooling or heating. Are refrigerant piping length and additional refrigerant chargenoted down?The refrigerant charge in the system might not be clear.a Indoor unitb LightingThe figure describes about a ceiling lighting, but a recessedceiling light is not restricted.c Air fanA If the air outlet is closed, space marked (A) should be 500 mm atleast.
