SiE33-102 InstallationGeneral Information 51FXYM-KF-Outdoor Air Processing Unit1. Install the drain pipes. Keep piping as short as possible and slope it downwards so that air may not remaine trapped inside thepipe. The diameter of the piping is the same as that of the connecting pipe (PS1B), and should be kept equalto or greater than that of the connecting pipe. Insulate the drain hose inside the building. There is negative pressure inside the unit relative to atmospheric pressure when the unit isrunning, so be sure to provide drain frap on the drain outlet. (See the figure) In order to prevent foreign matter from building up inside the piping, you should avoid curvesas much as possible, and arrange so the trap can be cleaned.Example drain trap installation If directly connected to the unit:Note: Be sure to insulate both sides of the drain trap connections. Install the drain trap so that the gap for cleaning is straight below. (±20˚ or less) If installing central drain piping, install according to the following figure.2. After piping work is finished, check drainage flows smoothly.3.2.10 Electrical WorkControl Wiring 1. Compatible types of wireWiring SpecificationsNotes: 1. Sheathed wire may be used for transmission winings, but they do not comply with EMI (Electromagneticlnterference) (EN55014). When using sheathed wire. EMI must conform to Japanese standardsstipulated in the Electric Appliance Regulatory Act. (If using a sheathed wire, the grounding shown inthe figure on the left is unnecessary.)2. For FXYA indoor unit, use sheathed wire.2. Problems arising from the use of unsuitable cablea) When cable less than 0.75 mm² is usedWhere the control wiring is particularly long the transmission signals may, for example, becomeunstable and the terminal relay cease to function. (Reduced voltage) The control system may becomeunduly subject to noise interference.Insulation(attached)Mark for aligning insulation and fittingInsulation for drain trap fitting(attached)Blind cap(To keep line clean)Drain trap(attached)Insulation (attached)3PA60998-14P-6100mmor more3PA60998-14P-7Wiring Type Shield Wire (2 wire) (See NOTE 1, 2)Size 0.75~1.25 mm²Si33-102.book Page 51 Tuesday, June 26, 2001 3:18 PMВсе каталоги и инструкции здесь: http://splitoff.ru/tehn-doc.html
