3.2.3. Installing the wall mounting fixture

sSince the indoor unit weighs near 30 kg, 66 lbs selection of the mounting location requires thorough consideration. If the wall does not seem to be strong enough, reinforce it with boards or beams before installation.

sThe mounting fixture must be secured at both ends and at the centre, if possible. Never fix it at a single spot or in any nonsymetrical way.

(If possible, secure the fixture at all the positions marked with a bold arrow.) (Fig. 3-4)

Warning:

If possible, secure the fixture at all positions indicated with a bold arrow.

Caution:

•The unit body must be mounted horizontally.

•Fasten at the holes marked with ▲ as shown by the arrows.

1Fasten a thread to the hole.

2The level can be easily obtained by hanging a weight from the string and aligning the string with the mark.

3.3. When embedding pipes into the wall (Fig. 3-5)

•The pipes are on the bottom left.

•When the cooling pipe, drain pipes internal/external connection lines etc are to be embedded into the wall in advance, the extruding pipes etc, may have to be bent and have their length modified to suit the unit.

•Use marking on the mount board as a reference when adjusting the length of the embedded cooling pipe.

•During construction, give the length of the extruding pipes etc some leeway.

3.4. Preparing the indoor unit

Rear, right and lower piping (Fig. 3-6)

1. Bind the cooling pipe and drain pipe together.

•Bind the pipes together with vinyl tape at three or more points. This will facilitate

passing the pipes through the wall.

2. Remove the corner box and knock out the knockout holes as necessary.

•Remove the corner box by pushing in a downward direction b, while at the same time, pressing in the upper side part of the corner box a.

1. Remove the under cover.

•Remove the under cover by sliding it towards the rear of the unit b, while at the

same time, pressing the two points marked by arrow heads a.

2. Remove the corner box and knock out the knockout holes as necessary.

3.5. Mounting the indoor unit

1.Affix the mounting plate to the wall.

2.Hang the indoor unit on the two hooks positioned on the upper part of the mount- ing plate.

Rear, right and lower piping (Fig. 3-8)

3.Affix the indoor unit.

4.After connecting the pipes, put the corner box back to where it was (follow the removal steps backwards).

3.Cut out a mounting piece from the packaging material.

4.Pull the indoor unit up towards yourself as shown in the figure below and slide the mounting piece in to the mounting plate using the mounting piece setting marks as reference.

5.After connecting the pipes and wiring, put the under cover back to where it was, and remove the mounting piece and affix the indoor unit as shown in the left figure.

6.Put the corner box back to where it was.
