2. Installation location
2.2.Servicespace(Fig.2-2)
• The dimensions of ceiling opening can be regulated within the range shown in
following diagram; so centre the main unit against the opening of ceiling, ensur-
ing that the respective opposite sides on all sides of the clearance between them
becomes identical.

BAir outlet

2.3.Ceilingopeningsandsuspensionboltinstallation
locations (Fig. 2-3)
• Make an opening in the ceiling 430 mm × 960 mm in size. This functions as a
check window and will be needed later during servicing.
• If the dimensions are not accurate, when the grille is installed there may be gaps
between it and the indoor unit. This may result in dripping water or other prob-
lems.
• When deciding on placement, consider carefully the space around the ceiling and
make your measurements generous.
• Ceiling types and building construction differ. Therefore you should consult with
the builder and decorator.
AThe centres of the ceiling opening and the indoor unit should be aligned.
  1 Outer side of grille
2Ceiling opening
  3 Bolt pitch
4Electric box
• Using the installation template (top of the package) and the gauge (supplied as
an accessory with the grille), make an opening in the ceiling so that the main unit
can be installed as shown in the diagram. (The method for using the template
and the gauge are shown.)
• Use M10 (3/8") suspension bolts.
*Suspension bolts are to be procured at the eld.
• After suspending the indoor unit, you will have to connect the pipes and wiring
above the ceiling. Once the location has been xed and the direction of the pipes
has been determined, place the refrigerant and drainage pipes, the wiring for the
remote controller, and the wiring that connects the indoor and outdoor units in
their desired locations before suspending the indoor unit. This is especially im-
portant in cases where the ceiling is already in existence.
1 Wooden structures (Fig. 2-4)
• Use tie beams (single storied houses) or second oor beams (2 story houses) as
reinforcing members.
• Wooden beams for suspending air conditioners must be sturdy and their sides
must be at least 6 cm long if the beams are separated by not more than 90 cm
and their sides must be at least 9 cm long if the beams are separated by as
much as 180 cm. The size of the suspension bolts should be ø 10 mm (3/8"). (The
bolts do not come with the unit.)
• Use channel, duct and other parts procured locally to suspend the indoor unit.
2 Ferro-concrete structures (Fig. 2-5)
Secure the suspension bolts using the method shown, or use steel or wooden
hangers, etc. to install the suspension bolts.

2. Installing the indoor unit
Check the pitch of the suspension bolt. (340 mm × 811 mm)
1.Thread washers 12 (supplied) and their nuts (procured locally) onto the sus-
pension bolt in advance. (Fig. 2-7)
* Do this in the following order (from the top): nut, insulated washer 2,washer
without insulation 1, 2 nuts.
* Position insulated washer 2with the insulated surface pointing down, as in the
gure.
2. Lift the unit into place, aligned properly with the suspension bolt. Pass the brack-
et between washers 1and 2, which are already in place, and secure it. Do the
same in all four places.
*
Make sure the suspension bolt extends 20 mm or more from the surface of the
ceiling. Otherwise you will not be able to install the cover panel (option).
3. If the long opening in the bracket and opening in the ceiling do not align, adjust
them until they do.

4. Check that the four corners are all level, using a spirit level or clear plastic tubing
with water in it. (Fig. 2-8)
* Make sure that any slant in the unit after installation is less than 0.5 degrees
(approx. 6 mm on the long dimension of the unit).
5. Tighten all the nuts. (Fig. 2-9)

thickness of 12 mm or more).
• The indoor parts of the drain pipe should be wrapped with polyethylene foam in-
sulation materials (specic gravity of 0.03, thickness of 9 mm or more).
• Apply thin layer of refrigerant oil to pipe and joint seating surface before tightening
are nut.
• Use 2 wrenches to tighten piping connections.
• Use refrigerant piping insulation provided to insulate indoor unit connections. In-
sulate carefully.

from the unit during servicing.
6. Secure the wires with the wiring clamp on the side of the electrical box.
7. Replace the parts you have removed to their original locations.
1. Connect the drain socket (supplied with the unit) to the drain port. (Fig. 3-5)
(Fix the tube using PVC adhesive then secure it with a band.)
2. Install a locally purchased drain pipe (PVC pipe, O.D. ø26).
(Fix the pipe using PVC adhesive then secure it with a band.)
3. Insulate the pipe. (PVC pipe, O.D. ø26)
4. Check that drain ows smoothly.
5. Insulate the drain port and drain socket with insulating material 7, then secure
the material with a band. (Both insulating material and band are supplied with

4.5. Settingaddresses(Fig.4-4)
(Be sure to operate with the main power turned OFF.)
• There are 2 types of rotary switch setting available: setting addresses 1 to 9 and
over 10, and setting branch numbers.
1How to set addresses
Example: If Address is “3”, remain SW12 (for over 10) at “0”, and match
SW11 (for 1 to 9) with “3”.
2 How to set branch numbers SW14 (Series R2 only)
Match the indoor unit’s refrigerant pipe with the BC controller’s end connection
number.
Remain other than series R2 at “0”.
• The rotary switches are all set to “0” when shipped from the factory. These
switches can be used to set unit addresses and branch numbers at will.
• The determination of indoor unit addresses varies with the system at site. Set
them referring to the Data Book.
Note:
PleasesettheswitchSW5accordingtothepowersupplyvoltage.
• SetSW5to240Vsidewhenthepowersupplyis230and240volts.
• Whenthepowersupplyis220volts,setSW5to220Vside.

sorinaremotecontroller(Fig.4-4)
If you want to sense room temperature with the built-in sensor in a remote control-
ler, set SW1-1 on the control board to “ON”. The setting of SW1-7 and SW1-8 as
necessary also makes it possible to adjust the airow at a time when the heating
thermometer is OFF.

transmissioncables(Fig.4-3)
• Connect indoor unit TB5 and outdoor unit TB3. (Non-polarized 2-wire)
The “S” on indoor unit TB5 is a shielding wire connection. For specifications
about the connecting cables, refer to the outdoor unit installation manual.
•
Install a remote controller following the manual supplied with the remote controller.
• Connect the remote controller’s transmission cable within 10 m using a 0.75 mm2
core cable. If the distance is more than 10 m, use a 1.25 mm2 junction cable.
1MA Remote controller
• Connect the “1” and “2” on indoor unit TB15 to a MA remote controller. (Non-
polarized 2-wire)
• DC 9 to 13 V between 1 and 2 (MA remote controller)
2 M-NET Remote controller
• Connect the “M1” and “M2” on indoor unit TB5 to a M-NET remote controller.
(Non-polarized 2-wire)

• Adjust the front panel so that it ts properly in the angle between the ceiling and
the wall, and install the securing bolts 2 (supplied with this grille) in their four
places at left and right, leaving them slightly loose. (Fig. 5-5)
• Next tighten the securing bolts 2and securing screws 3in the centre three
places.
• Finally tighten the securing bolts 2in the four places at left and right.
• At this point, make sure there are no gaps between the indoor unit and the front
panel, and between the front panel and the ceiling surface. If there are gaps, the
wind may come in and it may cause water to drip (Fig. 5-6).
* Tighten the securing bolts 2and securing screws 3completely.
• Replace the air lter and screw cover, and press the intake grille on the place
marked Push until you hear it snap into place.

5.2. Checksbeforesettinginplace(Fig.5-2,3)
• Before installing the front panel, make sure the indoor unit is square with the ceil-
ing opening (or parallel to the angle between the wall and the ceiling).
• Check that the four points where the front panel will be secured are in contact
with the ceiling surface.
• Check that the insulation for the refrigerant pipes, drainage pipes, etc. is in place
and that wiring connections and arrangements are complete.
