7 English(E) When outdoor units are installed in rows (on the rooftop, etc.)(1)When one outdoor unit is installed in each row(2)When two or more outdoor units are installed side by sideThe dimensional relationship between H, L and A is as shown in thetable below.5. CAUTIONS ON INSTALLATION• Before installation, confirm the strength and levelness of the founda-tion so that vibrations and noise are not generated.• Fix the outdoor unit securely on a rigid base with foundation bolts asshown in the foundation drawing below.(Prepare 4 sets of commercially available M12-type or equivalentfoundation bolts, nuts and washers.)• Use resin washers to prevent the paint from being scratched off andrusting.• The foundation bolts should be protruded by 15/16 in.(Refer to figure)〈〈Drain treatment〉〉• In a location where drain from the outdoor unit may cause troubles(for example, where drainage may splash on general passersby),perform the drain piping work using the drain plug (optional).• For drain treatment, space of at least 4 in. is required under the bot-tom frame of the outdoor unit.• In the drain piping work, make sure that drainage is dischargedsecurely.(When routing the piping downward, check for water leakage.)• A transportation metal in yellow and a washer are provided on theleg of the compressor for protecting the unit during transport.Remove them as described below.(1) Open the sound-proof cover as shown in the above figure.At this time, do not pull the sound-proof cover, and do not remove itfrom the compressor.(2) Remove the fixing nut.(3) Remove the transportation metal and the washer as shown in theabove figure.(4) Return and tighten the fixing nut again.(5) Return the sound-proof cover to achieve the former status.CAUTION• If the unit is operated with the transportation metal attached, abnor-mal vibration or sound may be generated.6. REFRIGERANT PIPING WORKCAUTION• Make sure to open the stop valves after finishing the pipingwork. (Refer to the table shown in “ 6-7 Additional refrigerantcharge”.)(Operating the air conditioner with the stop valve shut maydamage the compressor.)• Use R410A to add refrigerant. (The R410A refrigerant cylinder has apink stripe painted around it.)All field piping must be installed by a licensed refrigeration technicianand must comply with relevant local and national regulations.• BRAZING REFRIGERANT PIPINGDo not use flux when brazing copper-to copper refrigerant piping.(Particularly for the HFC refrigerant piping) Therefore, use the phosphorcopper brazing filler metal (BCuP) which does not require flux.(Flux has an extremely negative effect on refrigerant piping systems.For instance, if chlorine based flux is used, it will cause pipe corro-sion. Flux containing fluorine will damage refrigerant oil.)L AL ≤ H 0 L ≤ 1/2H 101/2H L ≤ H 12H L Installation is not allowed.4 or more8 or more 80 or more40 or moreA L60 or more 24 or more 120 or moreH15/16ResinwasherTransportation metal removal procedure5 1/21 3/45 1/224 3/8Air outlet side(13 5/8-14)13 3/411 3/88 5/84 5/8Bottom view(unit: inch)Drain hole16 5/824 1/8CompressorFixing nutWasherTransportationmetalSound-proof coverTurn in the arrow directionand remove it.
