NOTICE:
Certain models have external panels fabricated
from a premium grade of stainless steel designed
to inhibit corrosion. For such units, if the unit is
located in a coastal region or other area subjected
to high concentrations of salt, then the unit should
be hosed off after storms and monthly otherwise
to maintain its new appearance.
2. SAFETY CONSIDERATIONS
Pressures within the System — Split system
air conditioning equipment contains liquid and
gaseous refrigerant under pressure. Installation
and servicing of this equipment should be accom-
plished by qualifi ed, trained personnel thoroughly
familiar with this type of equipment. Under no
circumstances should the Homeowner attempt
to install and/or service the equipment.
Labels, Tags, Precautions — When working
with this equipment, follow all precautions in the
literature, on tags, and on labels provided with
the equipment. Read and thoroughly understand
the instructions provided with the equipment prior
to performing the installation and operational
checkout of the equipment.
Brazing Operations — Installation of equipment
may require brazing operations. Safety codes
must be complied with. Safety equipment (e.g.;
safety glasses, work gloves, fi re extinguisher,
etc.) must be used when performing brazing
operations.
WARNING:
Ensure all electrical power to the unit
is off prior to installing or servicing
the equipment. Failure to do so may
cause personal injury or death.
3. SITE PREPARATION
Unpacking Equipment — Remove the card-
board carton and User's Manual from the
equipment. Take care not to damage the tubing
connections when removing the carton.
Inspect for Damage — Inspect the equipment
for damage prior to installing the equipment at
4
the job site. Ensure coil fi ns are straight and, if
necessary, comb fi ns to remove fl attened and
bent fi ns.
Preferred Location of the Outdoor Unit at the
Job Site — Conduct a survey of the job site to
determine the optimum location for mounting
the outdoor unit. Overhead obstructions, poorly
ventilated areas, and areas subject to accumula-
tion of debris should be avoided. The outdoor
unit should be installed no closer than 18 inches
from the outside walls of the facility and in an
area free from overhead obstructions to ensure
unrestricted airfl ow through the outdoor unit.
Facility Prerequisites — Electrical power
must be supplied to the equipment. Electrical
power supplied must be adequate for proper
operation of the equipment. The system must
be wired and provided with circuit protection in
accordance with local building codes and the
National Electrical Code.
4. INSTALLING THE OUTDOOR UNIT
Slab Mount — The site selected for a slab mount
installation requires a stable foundation and one
not subject to erosion. The slab should be level
and anchored (if necessary) prior to placing the
equipment on the slab.
Cantilever Mount — The cantilever mount
should be designed with adequate safety factor
to support the weight of the equipment, and for
loads subjected to the mount during operation.
Installed equipment should be adequately se-
cured to the cantilever mount and levelled prior
to operation of the equipment.
Roof Mount — The method of mounting should
be designed so as not to overload roof structures
nor transmit noise to the interior of the structure.
Refrigerant and electrical line should be routed
through suitably waterproofed openings to pre-
vent water leaking into the structure.
5. INSTALLING THE INDOOR UNIT
The indoor section should be installed before
proceeding with routing of refrigerant piping.
Consult the installation instructions of the indoor
unit (i.e.: air handler, furnace, etc.) for details
regarding installation.
