3 INSTALLATION OF INDOOR UNIT

Ceiling opening and installation of hanging bolts

•Evaluate and determine the piping and wiring requirements inside the ceiling prior to the hanging of the unit.

•After installation place of the indoor unit has been determined, create opening in ceiling and install the hanging bolts.

•For the ceiling opening size and pitch for hanging bolts refer to the dimensional drawing and the supplied installation pattern.

•Once the ceiling void has been created, ensure that the drain pipe, refrigerant pipes, inter-connecting wires and all control wires are in place prior to installing the actual indoor unit.

Please procure the hanging bolts and nuts for installation of the indoor unit at local site.

How to use the supplied installation pattern

Installation of indoor unit

•Attach the nut (M10 or W3/8: Procured locally) and washer (Ø34 mm) to the hanging bolt.

•Put washers at either side of the T-groove on the hanging bracket of the indoor unit in order to hang the unit.

•Using a spirit level, check that all four sides are horizontal. (Horizontal positioned within 5 mm)

•Cut off the installation gauge from the installation pattern.

•Using the installation gauge check and adjust clearance between the indoor unit and the ceiling opening (1) (10 to 42 mm on each side). Ensure that the unit is level to the ceiling and within a distance of (2) 23 mm to 28 mm below.

The installation gauge has details of how to use printed on it.

Note) Install the indoor unit so that the end part of opening does not come into contact with the drain socket piping.

•Install the indoor unit after installation of the hanging bolts.

•Using the supplied pattern attach it to the indoor unit using the supplied fixing screws (M5 × 16L 4off). (Screw pattern to the ceiling panel hanging brackets of the indoor unit)

•When creating the opening ensure it is as per the outer dimensions of the supplied pattern.

These screws are exclusive to the installation pattern. When installing the ceiling panel, the other exclusive screws attached to the ceiling panel (sold separately) are used.)

REQUIREMENT

Before installation of the indoor unit be sure to remove the transportation cushion found between the fan and the bell mouth.

Running the unit without removing the cushion may damage the fan motor.

Installation of ceiling panel (Sold separately)

Install the ceiling panel after completion of the installation of the indoor unit, including all piping and wiring.

Install the ceiling panel as per the supplied Installation Manual.

Treatment of ceiling

The ceiling differs according to the structure of the building. For details, consult your architect.

In the process after the ceiling panels have been removed, it is important to reinforce the ceiling construction and ensure the ceiling remains in a horizontal position. This is to prevent possible vibration of the ceiling panels.

1.Cut and remove the ceiling material.

2.Reinforce the cut surface of the ceiling construction and add support for fixing the end of ceiling panel.

Installation of hanging bolt

Use M10 hanging bolts (4 off, locally procured).

When mounting the unit, set the pitch of the hanging bolts according to the size of the unit as detailed on the dimensional drawing.

Be sure to remove the cushion for transportation between the fan and the bell mouth.

Check the installation dimensions of the indoor unit and the ceiling opening are correct and then install.

REQUIREMENT

Ensure the ceiling panel is mated to the ceiling surface or the indoor unit.

If the panel and unit are not mated together this may result in the formation of dew condensation causing a possible water leak.

First remove the 4 corner caps from the ceiling panel and fit to the indoor unit.
