Preparation
Step 1-2 Choosing the installation
location
If using a multi system, install as described in the
installation manual supplied with the outdoor unit.
WARNING
•
Verify that a dedicated circuit breaker and a disconnect
switch of the appropriate sizes for the air conditioner
are preinstalled and available for use.
•
Verify that the voltage and frequency of the power
supply comply with the rated voltage as defined on the
unit name plate.
•
Verify that a suitable grounding connection is available.
•
Do not install this appliance in an environment
containing hazardous substances or close to equipment
that releases open flames.
•
Do not install this appliance near a heater or flammable
material.
CAUTION
•
The manufacturer shall not be responsible for damage
occurring as a result of the wrong voltage being
applied to this air conditioner.
•
The indoor and outdoor units must be installed in
compliance with minimum clearances to ensure that
both units are accessible from both sides and can be
maintained or repaired. Insufficient clearance may
reduce product performance, generate excessive noise,
and reduce the life of some unit components.
IMPORTANT
•
Any changes or modifications to the installation
described in this manual that are not expressly
approved by the manufacturer could void the
manufacturer's warranty.
To determine where to locate the indoor and outdoor units,
you must survey the entire site and consider many variables.
The goal is to select locations that comply with all safety
precautions while also minimizing the total effort involved.

Indoor unit location requirements
WARNING
•
Do not install the unit in a humid, oily, or dusty location
or in a location exposed to direct sunlight, water, or rain.
•
Make sure that the wall can support the unit weight.
Examine the area that the customer wants to be air
conditioned. Consider the following:
•
What wall location will meet minimum clearances and
provide optimal product performance?
•
Will the wall provide adequate support for the unit
weight (wall with stud construction or concrete)? If
applicable, where are the studs?
•
Where will you place the wall penetration for
routing the piping bundle (consisting of power and
communication cables, refrigerant pipes, and the drain
hose) through the wall to the outdoor unit? Will the
hole intersect any plumbing or wires in the wall?
•
Is the location as close as possible to where the outdoor
unit will be installed, to minimize the length of piping
and cables?
•
Will the condensate drain inside the room, through the
wall penetration to the outdoor unit, or be connected to
a condensate pump?
NOTE
•
This manual covers a typical gravity-drain installation
where the drain hose is routed to the outdoor unit
through a hole in the wall.
