Wall Sleeve Installation - Lennox VWMA007S4 Installation Instructions Manual

WALL SLEEVE INSTALLATION

The utility bundle may be routed out of the back of the unit
or out either side. If the bundle is to be routed out the back
through an external wall, use a fi eld-provided wall sleeve to
protect the utility bundle. NOTE - If the utility bundle will be
routed out the side of the indoor unit and up the wall above
a false ceiling, continue to the next section.
1. Prior to making the hole and installing the wall sleeve
for the utility bundle, check to ensure that there are no
other utilities located in the wall behind the hole location.
WARNING
!
Electric Shock Hazard. Can cause injury or death.
Avoid location where electric wiring or conduits may
be present inside the wall.
2. Cut a hole in the wall using a suitable hole saw. Hole
should be at a slight downward slant - 3/16" to 3/8"
toward the outdoor side.

3. Measure the thickness of the wall from the inside edge
to the outside edge and cut the fi eld-provided wall
sleeve at a slight angle 1/4" (6 mm) shorter than the
thickness of the wall.

4. Place the provided plastic cover over the end of the
pipe that will be visible from the inside wall and insert
the pipe in the wall.
NOTE - When passing bundled services through an exterior
brick or concrete wall, protect the copper pipes and wiring
from the effects of these construction materials by using a
sleeve made of a suitable material. The integrity of copper
pipe and wiring can deteriorate when exposed to these
construction materials

shown.
INSTALL UNIT ON WALL MOUNTING PLATE
1. A length of fi eld-provided fl exible condensate piping
should be connected to the drain prior to securing the
unit to the wall mounting plate.
2. If the factory-provided refrigerant piping connections
and fi eld-provided fl exible condensate piping are long
enough to enable fi nal fi eld connections after unit is
installed on wall mounting plate, use fi eld-provided tape
to bundle them together.
3. The utility bundle may be routed out of the back of the
unit or out either side. If the bundle is to be routed
out the back through an external wall, feed the utility
bundle through the wall sleeve. If the utility bundle is
to be routed out of the side of the indoor unit and up
an inside wall, carefully form the utility bundle so that it
makes a gentle 90° turn.
4. Align the back of the indoor unit with the hooks at the
top of the wall mounting plate. Move the unit from side
to side to make sure that it settles securely.
5. The bottom of the unit can be lifted to facilitate refrigerant
piping and condensate drain connections, if necessary.
