1. Determine the square foot of reach room and pick the appropriate indoor unit for that room. Oversizing
is not always better. If the room is too small and the head is too large, the unit will short cycle and not
remove the humidity from the room.
• Up to 350 sq. feet = 9,000 BTU
• Up to 500 sq. feet = 12,000 BTU
• Up to 750 sq. feet = 18,000 BTU
2. Determine where to install the indoor head in each room.
• An exterior wall works best. If it must be on an interior wall you may need a condensate pump to
remove the condensation in the summer. This is purchased separately.
3. Determine where the outdoor unit will be placed.
• Try to place the outdoor unit centrally to all of the indoor units.
• Keep in mind you will need to run 230v power to the unit, so try to keep it close to your electrical
panel in the house.
4. Now that you have the location of the heads in the building and the outdoor unit outside, you will need
to gure out how long each of the line sets will be.

STEP 1. MARKING THE WALL (USING TEMPLATE)
The mounting bracket is the device on which you will mount the indoor unit, it is the silver bracket on the
back of the indoor unit. A mounting template has been provided to assist you with proper hole and indoor
unit placement to assist you with the proper location of the holes for the indoor unit mounting bracket and the
power cable / condensate drain pipe.
In the location chosen during pre-planning, locate studs in the wall using a stud nder. If you cannot nd a
stud, you will need to use wall anchors.
1. Place the mounting plate template against the wall, in a location:
• On an exterior wall, at least 6 inches (15.25 cm) from the ceiling and 4.75 inches (12 cm) from adjacent
wall (refer to Figure 1.1).
• Where two studs can be drilled directly into to support the mounting bracket.
• Where the line set hole, as marked on the template, will be free of electrical wiring, plumbing, and other
sensitive components that may be hidden in the wall.
2. Use a level to make sure your template is level.
3. Using something sharp like a nail, mark the areas of the wall where you will be drilling your screws and
the line set hole.
4. Remove the mounting template from the wall.
6 in. (15.25 cm)
4.75 in. (12 cm)
Figure 1.1
NOTE: We strongly advise using the hole located on the right side of the template, as this is where the
indoor unit will have the line set bundle located. If you choose to move the bundle to the left side of the
unit, then you will need to make your line set connections inside, before mounting the unit.

CAUTION
STEP 3. DRILLING THE LINE SET BUNDLE HOLE
STEP 4. INSTALLING THE WALL UNIT
1. Using a 2.5 in. (63.5mm) core drill, drill a hole in the wall (Figure 3.1). 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
1/2 in. (5 – 7mm) to ensure proper drainage for water condensation.
2. From the outside, place the protective wall cu/sleeve in the hole. This protects the edges of the hole
and seals it when you nish the installation process.
1. Grip the refrigerant copper piping at the base of the bend.
2. Slowly, with even pressure, bend the piping perpendicular to the indoor unit. Do not kink or damage
the piping during the process.
3. CAUTION: Be extremely careful not to kink or damage the piping while bending them away from the
unit. Any kinks in the piping will aect the unit’s performance.

STEP 5. PREPARING THE BUNDLE
Before passing the refrigerant piping, drain hose and communication cable through the wall hole, you must
bundle them together to save space. Make sure that the drain hose is at the bottom of the bundle. Putting the
drain hose at the top of the bundle can cause the drain pan to overow and backup, which can lead to re,
water damage or both. (Figure 5.1)
1. Double-check that the ends of the refrigerant pipes are sealed with color coded caps, preventing dirt
or foreign materials from entering the pipes. Do not remove these caps.
2. Slowly pass the wrapped bundle of refrigerant pipes, drain hose, and communication cable through the
hole in the wall. (Figure 5.2)
3. Hook the top of the indoor unit on the top hook of the mounting plate.
4. Check that the unit is hooked rmly on the mounting plate by applying slight pressure to the left and
right sides of the unit. The unit should not move or shift.
5. Using even pressure, push down on the bottom half of the unit. Keep pushing down until the unit
snaps onto the hooks along the bottom of the mounting plate.
