Drill Wall Hole For Connective Piping - Pioneer Inverter+ WAS Series Installation Manual

Refer to the following diagram to ensure these recommended distances from walls and ceiling:
8~12cm (3~5 in)
or more
Step 2: Attach mounting plate to the 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.
NOTE FOR CONCRETE OR BRICK WALLS:
If the wall is made of brick, concrete, or similar
material, drill 5mm-diameter (3/16 in-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.

Step 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 on the
next page to help you determine the optimal
position. The wall hole should have a 65mm
(2.5in) diameter at least, and at a slight
downward angle to facilitate drainage.
2.
Using a 65mm (2.5 in) or 90mm(3.5 in)
(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
(3/16~5/16 in). This will ensure proper water
drainage. (See Fig. 3.2)
3. Place the protective sleeve in the hole. This
protects the edges of the hole and will help
seal it when you finish the installation process.
CAUTION
When drilling the wall hole, make sure to
avoid wires, plumbing, and other sensitive
components.
