CONDENSING UNIT
AIR CONDITIONING
INSTALLATION & SERVICE REFERENCE
Important Safety Instructions
The following symbols and labels are used throughout this
manual to indicate immediate or potential safety hazards. It is
the owner's and installer's responsibility to read and comply
with all safety information and instructions accompanying these
symbols. Failure to heed safety information increases the risk
of personal injury, property damage, and/or product damage.
WARNING
HIGH VOLTAGE!
Disconnect ALL power before servicing.
Multiple power sources may be present.
Failure to do so may cause property damage,
personal injury or death.
WARNING
ONLY individuals meeting the requirements of an
"Entry Level Technician" as specified by the Air
Conditioning and Refrigeration Institute (ARI) may use
this information. Attempting to install or repair this
unit without such background may result in product
damage, personal injury, or death.
Shipping Inspection
Always keep the unit upright; laying the unit on its side or top
may cause equipment damage. Shipping damage, and subse-
quent investigation is the responsibility of the carrier. Verify
the model number, specifications, electrical characteristics,
and accessories are correct prior to installation. The distribu-
tor or manufacturer will not accept claims from dealers for trans-
portation damage or installation of incorrectly shipped units.
Codes & Regulations
This product is designed and manufactured to comply with
national codes. Installation in accordance with such codes and/
or prevailing local codes/regulations is the responsibility of the
installer. The manufacturer assumes no responsibility for equip-
ment installed in violation of any codes or regulations.
The United States Environmental Protection Agency (EPA)
has issued various regulations regarding the introduc-
tion and disposal of refrigerants. Failure to follow these
regulations may harm the environment and can lead to
the imposition of substantial fines. Should you have any
questions please contact the local office of the EPA.
If replacing a condensing unit or air handler, the system must
be manufacturer approved and Air Conditioning and Refrigera-
tion Institute (ARI) matched. NOTE: Installation of unmatched
systems is strongly discouraged.
Operating the unit in a structure that is not complete (either as

part of new construction or renovation) will void the warranty.
Installation Clearances
Special consideration must be given to location of the con-
densing unit(s) in regard to structures, obstructions, other units,
and any/all other factors that may interfere with air circulation.
Where possible, the top of the unit should be completely unob-
structed; however, if vertical conditions require placement be-
neath an obstruction there should be a minimum of 60
inches between the top of the unit and the obstruction(s).
The specified dimensions meet requirements for air circulation
only. Consult all appropriate regulatory codes prior to deter-
mining final clearances.
Another important consideration in selecting a location for the
unit(s) is the angle to obstructions. Either side adjacent the
valves can be placed toward the structure provided the side
away from the structure maintains minimum service clearance.
Corner installations are strongly discouraged.

This unit can be located at ground floor level or on flat roofs. At
ground floor level, the unit must be on a solid, level foundation
that will not shift or settle. To reduce the possibility of sound
transmission, the foundation slab should not be in contact with
or be an integral part of the building foundation. Ensure the
foundation is sufficient to support the unit. A concrete slab
raised above ground level provides a suitable base.

They are designed for tion having a vapor barrier equivalent to ductwork insulation, 208/230 volt single phase applications. - Page 25 PRODUCT DESIGN The ASX [16 & 18] and ASZ [16 & 18] series split system units use a two-stage scroll compressor. The two-step modulator has an internal unloading mechanism that opens a bypass port in the first compression pocket, effectively reducing the displacement of the scroll.
