Indoor Unit Installation - Midea BREEZELESS Technical Manual

3. Indoor Unit Installation

3.1 Service space for indoor unit
15cm (5.9in) or more
12cm (4.75in)
or more
2.3m (90.55in) or more
3.2 Attach mounting plate to wall
• The mounting plate is the device on which you
will mount the indoor unit.
1. Remove the screw that attaches the mounting plate to
the back of the indoor unit.
2. Place the mounting plate against the wall in a location
that meets the standards in the Select Installation Location
step. (See Mounting Plate Dimensions for detailed
information on mounting plate sizes.)
3. Drill holes for mounting screws in places that:
• have studs and can support the weight of the unit.
• correspond to screw holes in the mounting plate.
4. Secure the mounting plate to the wall with the screws
provided.
5. Make sure that mounting plate is flat against the wall.
• Mounting plate dimensions
Different models have different mounting plates. For
the different customization requirements, the shape of
the mounting plate may be slightly different. But the
installation dimensions are the same for the same size of
indoor unit.

• Note for concrete or brick walls:
If the wall is made of brick, concrete, or similar material,
drill 5mm-diameter (0.2in-diameter) holes in the wall
and insert the sleeve anchors provided. Then secure the
mounting plate to the wall by tightening the screws
directly into the clip anchors.
3.3 Drill wall hole for connective piping
You must drill a hole in the wall for refrigerant piping, the
drainage pipe, and the signal cable that will connect the
indoor and outdoor units.
1. Determine the location of the wall hole based on the
position of the mounting plate. Refer to Mounting Plate
Dimensions.
2. Using a 65mm (2.5in) or 90mm(3.54in) (depending on
models )core drill, drill a hole in the wall. Make sure that
the hole is drilled at a slight downward angle, so that the
outdoor end of the hole is lower than the indoor end by
about 5mm to 7mm (0.2-0.27in). This will ensure proper
water drainage.
3. Place the protective wall cuff in the hole. This protects
the edges of the hole and will help seal it when you finish
the installation process.
NOTE: When drilling the wall hole, make sure to avoid
wires, plumbing, and other sensitive components.

3.4 Prepare refrigerant piping
The refrigerant piping is inside an insulating sleeve
attached to the back of the unit. You must prepare the
piping before passing it through the hole in the wall.
