1. Detach the mounting plate from the unit.
2. Place mounting plate on wall where unit will be installed
and mark the mounting holes. See Fig. 5. Be sure the
mounting hole marks are positioned over the wall studs.

3. Mark the condensate and refrigerant piping route. If
necessary, cut a hole in the wall to route the piping.
4. Secure the mounting plate with screws that can support
the weight of the unit. For nominal weight of the unit, see
Table 1.
5. Make sure mounting plate is level and flush with the wall.
6. Secure the unit in position by lifting the unit over the
mounting plate. Make sure the hook on the mounting
plate aligns with the slot on the back of the unit. To ensure
proper fit, slide the unit sideways. If the unit is locked in
the correct position, it should not move.
Step 4 — Connect Piping
GENERAL —
1. For condensate and refrigerant piping, lift the unit from
the bottom making sure the unit is still attached to the
mounting plate at the top. See Fig. 6.

2. Introduce temporary cushioning material to maintain the
space needed to connect the piping and to avoid damage
to the unit and wall. See Fig. 6.

3. When the piping connections are completed, remove the
cushioning material and make sure the unit is flush with
the wall.

piping. When installing condensate piping, follow these
recommendations:
• Condensate drain should slope downward in the
direction of condensate flow.
• DO NOT install any U bends or dump condensate
line in a sump filled with water. See Fig. 7.
Fig. 7 — Condensate Piping, Poor Installation
• When multiple units are connected to a common
condensate drain, ensure that drain is large enough
to accommodate the volume of condensate from all
units. It is also recommended to have an air vent in
the condensate piping to prevent any air locks.
• Condensate piping must not be installed where it
may be exposed to freezing temperatures.
• Condensate piping can be routed in one of the four
directions shown in Fig. 8.

• While routing the condensate from right to left,
behind the unit, make sure all the piping is wrapped
and placed in the piping chase as shown in Fig. 9.
