40MBAB: Installation Instructions

INSTALLATION REQUIREMENTS

Review the following information before installing the unit:
• Do not install the indoor units near a direct source of heat such as
direct sunlight or a heating appliance.
• Allow sufficient space for airflow and unit servicing. See Fig. 8 — on
page 6 for the minimum required distances between the unit and the
walls or ceilings.
• Communication wiring must be at least 3 ft. (1m) away from all
electromagnetic interference (televisions, radios, etc.) sources.
Interference is still possible even if this distance is maintained.
• Ensure any hanger used is strong enough to withstand the unit's
weight.
• If the indoor unit is installed in an unconditioned space, running for
long periods of time when the temperatures are outside the
recommended indoor unit operation ranges, it is recommended that the
installer seal all corners of the indoor unit to prevent any leaks and add
insulation material (13/32 to 13/16 in (10-20 mm)) to the entire surface
of the indoor unit to avoid condensation or heat transfer.
NOTE: Nuisance sweating may occur if the unit is installed in a high
humidity environment with low airflow.

WARNING
PRODUCT INSTALLATION
• Installation must be performed by an authorized dealer or
specialist. A defective installation can cause water leakage,
electrical shock, or fire.
• The installation must be performed according to the installation
instructions. Improper installation can cause water leakage,
electrical shock, or fire. (In North America, installation must be
performed in accordance with the requirements of NEC or CEC
by authorized personnel only.)
• Contact an authorized service technician for repair or maintenance
of this unit. This appliance must be installed in accordance with
local codes.
• Only use the included accessories, parts, and specified parts for
installation. Using non-standard parts can cause water leakage,
electrical shock, fire, or unit failure.
• Install drainage piping according to the instructions in this manual
and in accordance with local codes. Improper drainage may cause
water damage to your home and property.
• For units that have an auxiliary electric heater installed, ensure 1"
of clearance from any combustible materials for first 3 feet (1
meter) of plenum and duct work exiting the unit.
• DO NOT install the unit in a location that may be exposed to
combustible gas leaks. If combustible gas accumulates around the
unit, it may cause a fire.
• DO NOT turn on the power until all work has been completed.
• When moving or relocating the system, consult experienced
service technicians for the disconnection and re-installation of the
unit.
NOTE: DO NOT install the indoor or outdoor units in a location with
special environmental conditions. For those applications,
contact your Ductless representative.
Manufacturer reserves the right to change, at any time, specifications and designs without notice and without obligations.
Securely install the indoor unit on a structure that can sustain its
weight. If the structure is too weak, the unit may fall and cause
personal injury, unit and property damage, or death.
DO NOT install the indoor unit in a bathroom or laundry room as
excessive moisture can short the unit and corrode the wiring.
Install the indoor and outdoor units, cables and wires at least 3.2 ft
(1m) from televisions, routers, computer equipment or radios to
prevent static or image distortion. Depending on the appliances, a
3.2 ft (1m) distance may not be sufficient.
If the indoor unit is installed on metal, it must be electrically
grounded.

Unpack the unit and move to the final location. Remove the carton, taking
N/A
care not to damage the unit. Inspect the equipment for damage prior to
installation. File a claim with the shipping company if the shipment is
damaged or incomplete. Locate the unit rating plate, which contains the
proper installation information. Check the rating plate to be sure the unit
matches the job specifications.
The indoor unit should be installed in a location that meets the following
requirements:
• Enough room for installation and maintenance
• Enough room for the lineset and drainpipe
• A structure that can sustain the weight of the indoor unit
• The air inlet and outlet are not impeded
• There is no direct radiation from heaters
DO NOT install the unit in the following locations:
• Areas with oil drilling or fracking
• Coastal areas with high salt content in the air
• Areas with caustic gases in the air, such as near hot springs
• Areas with power fluctuations, such as factories
• Enclosed spaces, such as cabinets
• Areas with strong electromagnetic waves
• Areas that store flammable materials or gas
• Rooms with high humidity, such as bathrooms or laundry
rooms.
