4. Decorative Panel Installation
Temporarily tighten the two panel mounting screws (long, supplied) diagonally
from each other as shown in Diagram 4 prior to installing the decorative panel.
(Screw in the long panel mounting screws until their first thread has gone
through the nut on the unit as shown in Diagram 5.) Finally, check that the auto
vane connector is definitely set in the direction of the piping before commencing
installation.

C Second stage bolt
E Panel Mounting Bolt (long)
Once units are directionally aligned, fit the notched holes of the panel body's
intake port over the long panel mounting bolts. (See Diagram 6.) First fit the two
holes at the side opposite the piping followed by the two holes at the piping side.
(See Diagram 12.) (Inwardly push the panel mounting bolts at the piping side to
make work easier.) Note that the panel body can be temporarily secured in this
state but may become dislodged if the panel is raised or strongly shaken. Use
the two short mounting screws to hold the other two corners.

Next, pass the vane motor lead wire through the side frame hole and the channel
on the narrow side of the drain pan. (See Diagram 8.)

In the case of Model 125
When removing the connector cover (screwed at two places) as shown in
Diagram 7, the electrical box is exposed. Find the vane motor connector.
Connect the two connectors (for vane motor drive and limit switch) leading from
the panel to each connector supplied with the electrical box. (See Diagram 8.)
* Gather the lead wire into the tie anchor provided to prevent it from becoming
trapped in the service panel.
* Never force the auto vane when handling, as doing so may cause system
failure.
• Securing the Decorative Panel
Raise the decorative panel into position and tighten the second stage panel
mounting bolts (long) until the panel touches the ceiling surface. (See Diagram
10.) Also, only in the case of the model 100, 125, the truss bolts and washers
provided should be used to secure the panel against the central section of the
main unit. (See Diagram 11.)

• Panel Bolt Tightening Order
1. Alternately and evenly tighten the two truss bolts on the middle section of the
panel (only in the case of model 100,125).
2. Once item 1. has been completed, tighten the long and short mounting bolts
temporarily tightened in Diagrams 5 and 6 and the truss bolts. (See Diagram
12.)

NOTE:
The panel may warp if the tightening order is not adhered to or temporary
tightening was not performed.
* Evenly tighten the four bolts (six bolts the panel for model 100,125) so that
there are no gaps between the unit body and decorative panel and between
the decorative panel and ceiling surface.
* If there are gaps between the unit body and decorative panel, air flow will be
insufficient, which may cause condensation and moisture dripping. Also, if
there are gaps between the decorative panel and ceiling surface, panel
condensation and ceiling smudging may occur. (See Diagram 13.)

* Recheck the suspension status of the main unit if installation of the panel is
not successful.
5. Service Panel Installation
• Service Panel Installation
Slot in one side of the service panel and then move it in the order shown in
Diagram 14 to install.
[Diagram 14] (P.4)
* Be sure to slot the anti-fall wires into the holes on both sides of the panel to
prevent accidents. (See Diagram 15.)

6. Checking Auto Vane Movement
Implement the contents in either the main unit installation manual (Trial
Operation) or the instruction manual to check the movement of the auto vane.
7. Method for Dividing Air Output
(Only in the case of model 40, 63, 100)
• The left and right auto vanes can be individually set to divide the air output.
(See Diagram 16.)

• Vane Securing Method
- Remove the vane motor cover of the vane to be secured.
The catches holding the cover may break if the cover is forcefully removed.
Press the catches with a minus screwdriver to aid easy removal. (See
Diagram 17.)
[Diagram 17] (P.5)

- Remove the connector connected to the vane. The connector is locked, so
be sure to hold down the lock release button when removing the connector.
(See Diagrams 18 and 19.)

- Remount the vane motor cover in reverse order to the removal.
- Slowly align the vane in the desired setting direction.
8. Air Flow Distribution (7:3) Method
• An air deflector (sold separately) can be used to distribute the supply air on
the left and right in the proportion of 7 to 3.
* Only in the case of the panel model 40,63, 100 The airflow types shown in
Diagram 20 can be selected if the distributor is combined with the air
output divider described in item 7.
