1-371CAUTION7. HOW TO INSTALL THE OUTDOOR UNIT1. Installing the Outdoor UnitUse concrete or a similar material to make the base,and ensure good drainage.Ordinarily, ensure a base height of 5 cm or more.If a drain pipe is used, or for use in cold-weatherregions, ensure a height of 15 cm or more at the feeton both sides of the unit.(In this case, leave clearance below the unit for thedrain pipe, and to prevent freezing of drainage waterin cold-weather regions.)Refer to Fig. 1-17 for the anchor bolt dimensions.Be sure to anchor the feet with anchor bolts (M10).In addition, use anchoring washers on the top side.(Use large square 32 × 32 SUS washers with JISnominal diameter of 10.)

Drainage WorkFollow the procedure below to ensure adequate drainingfor the outdoor unit.For the drain port dimensions, refer to Fig. 1-17.Ensure a base height of 15 cm or more at the feet onboth sides of the unit.3. Routing the Tubing and WiringThe tubing and wiring can be extended out in 4 directions:front, rear, right, and down.The service valves are housed inside the unit.To access them, remove the inspection panel.(To remove the inspection panel, remove the 3 screws,then slide the panel downward and pull it toward you.)(1)(2)If the routing direction is through the front, rear, or right,use a nipper or similar tool to cut out the knockout holes forthe inter-unit control wiring outlet, power wiring outlet, andtubing outlet from the appropriate covers A and B.If the routing direction is down, use a nipper or similar toolto cut out the lower flange from cover A. (Fig. 1-18)Route the tubing so that it does not contact the compressor, panel, or other partsinside the unit. Increased noise will result if the tubing contacts these parts.When routing the tubing, use a tube bender to bend the tubes.In cold-weather regions, in order to prevent drainage water from freezing, do notinstall the drain socket cap. Also take steps to prevent water from accumulatingaround the unit.1.2.3.Inter-unit control wiringoutletInspection panelPower wiring outletCover ATubing outletCover BRightDownRearFrontUnit: mm
