4. HOW TO INSTALL THE OUTDOOR UNIT

4-1. Installing the Outdoor Unit

	Use concrete or a similar material to create the base,
	and ensure good drainage.
	Ordinarily, ensure a base height of 2". or more. If a
	drain pipe is used, or for use in cold-weather regions,
	ensure a height of 6". or more at the feet on both sides
	of the unit. (In this case, leave clearance below the unit
	for the drain pipe, and to prevent freezing of drainage
	water in cold-weather regions.)
	Refer to the Fig. 1-10 for the anchor bolt dimensions.
	Be sure to anchor the feet with the anchor bolts (M10).
	In addition, use anchoring washers on the top side. (Use
	large square 32×32 SUS washers with diameters of
	10.) (Field supply)
	4-2. Drainage Work
	Follow the procedure below to ensure adequate draining
1	for the outdoor unit.

For the drain port dimensions, refer to the fi gure at right.

Ensure a base height of 6 in. or more at the feet on both sides of the unit.

4-3. Routing the Tubing and Wiring

The 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) If the routing direction is through the front, rear, or right, use a nipper or similar tool to cut out the knockout holes for the inter-unit control wiring outlet, power wiring outlet, and tubing outlet from the appropriate covers A and B.

CAUTION

Fig. 1-11

Route the tubing so that it does not contact the compressor, panel, or other parts inside the unit. Increased noise will result if the tubing contacts these parts. When routing the tubing, use a tube bender to bend the tubes.
