Read Your Warranty
Please read the separate warranty document completely. It
contains valuable information about your system.
1. GENERAL INFORMATION
Read the following instructions completely before performing
the installation.
Condensing Unit Section — Each condensing unit is
shipped with a refrigerant charge adequate to operate the
outdoor section with an indoor matching coil or air handler
and 15 feet of refrigeration line.
NOTE: DO NOT USE ANY PORTION OF THE CHARGE
FOR PURGING OR LEAK TESTING.
Matching coils and air handlers are shipped with a small
holding charge to pressurize them to keep out contaminants.
To release the pressure, read the indoor section of the
installation instructions carefully.
Liquid and Suction Lines — Refrigerant grade copper
tubing should be used when installing the system. Refrigerant
suction line tubing should be fully insulated.
Field Connections for Electrical Power Supply — All
wiring must comply with the current provisions of the "National
Electrical Code" (ANSI C1.) and with applicable local codes
having jurisdiction. Size of electrical conductors and circuit
protection must be in compliance with the information listed
on the outdoor unit data label.
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 accomplished by qualified, trained
personnel thoroughly familiar with this type of equipment.
Under no circumstances should the homeowner attempt to
install and/or service the equipment without proper
supervision from trained and qualified service personnel.
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.
Labels, Tags, Precautions — When working with this
equipment, follow all precautions in 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.
3. SITE PREPARATION
Unpacking Equipment — Remove the cardboard carton
and Homeowner's Package from the equipment.
Inspect for Damage — Inspect the equipment for damage
prior to installing the equipment at the job site. Ensure coil
fins are straight and, if necessary, comb fins to remove
flattened and bent fins.
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 accumulation 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 airflow
through the outdoor unit.
Facility Prerequisites — 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.
Minimum Circuit Ampacity — Electrical wiring to the
equipment must be compatible and in compliance with the
minimum circuit ampacity listed on the outdoor unit data
label.
Maximum Fuse/Circuit Breaker Size — Circuit protection
for the outdoor unit must be compatible with the maximum
fuse/circuit breaker size listed on the outdoor unit data label.
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 the mount is subjected to
during operation. Installed equipment should be adequately
secured 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 lines
should be routed through suitably waterproofed openings to
prevent water leaking into the structure.
