Regarding the positioning anchor bolts of thedepth direction, select one of three types according to theinstallation site. (See Fig. 3-2 A, B, C.)Normally, select the position “A”. When removing theconnection tube in a downward direction, select the position“B”.(2) When only using a single outdoor unit, see the Figure 3-2.In case of the combination with different units, refer to“SUPPLEMENT”.* When positioning the anchor bolt at “B” or “C”, make asufficient space bewteen the units or from the wall forinstallation.(Make a space between the units wider than 180mm andleft and right space wider than 250mm from the wall.)(3) The vibration insulator or the like should be kept secure tosatisfy the width and depth of 100mm for the plate legs.(See the dimensions marked by the asterisk at Fig. 3-4d -3-4g.) Use a washer from the upper direction larger thanthe hole size for fixing the installation. The models 18 hpand 20 hp have four (4) anchor volts respectively as sameas others. Two models, however, additionally need thevibration insulator under the plate leg at the central locationfor the installation site. Screw or wire the vibration insulatorat the center of the unit to the rack or the basement.Be sure to use the same thickness of all vibration insulatorsand make adjustment so that they will become the sameheight each other. (Fig. 3-3 and Fig. 3-4)• According to the installation site, you may choose the setting position inthe depth direction of the anchor bolt from “A”, “B” or “C”.A :894 (Installation hole pitch) * The tubing is routed out from the front.B :730 (Installation hole pitch) * The tubing is routed out from the bottom.C :730 (Installation hole pitch)• Below shows vibration insulator position when setting anchorbolt at position A (Fig.3-2).* Need the vibration insulator under the plate leg at the centrallocation for the installation site.Model : 8 hp, 10 hp, 12 hp, 14 hp, 16 hpModel : 18 hp, 20 hpInstallation anchor hole(8 – 15 × 21 elongated holes) Unit: mmUnit: mmFig. 3-2aFig. 3-2b(Installation hole pitch)AirintakeAirintakeTop viewInstallation anchor hole(8 – 15 × 21 elongated holes)Air intakeAir intakeAirintakeAirintakeTop viewUnit: mmFig. 3-2cTop viewInstallation anchor hole(8 – 15 × 21 elongated holes)Air intakeAirintakeAirintake(Installation hole pitch)(Installation hole pitch)(Detailed view of anchor hole)Unit: mm8 – 15 × 21 elongated holeFig. 3-3Unit: mmPlate leg (left) Plate leg (right)(Installation hole pitch)Vibration insulatorElectrical wiring port(bottom)Tubing port (bottom)Plate leg (left) Plate leg (right)Vibration insulatorElectrical wiring port(bottom)(Installation hole pitch)Tubing port (bottom)Vibration insulatorFig. 3-4aPlate leg (center)
