SECTION II - Unit Mounting
This section describes appropriate methods for mounting and securing the Allegiance /
Heritage 16, however, if these units are to be mounted in a region where high winds are an
issue, please refer to the American Standard BAYECMT001 extreme conditions mounting
kit installation instructions publication Number #18-HE44D1-* (* latest version ). The
BAYECMT001 is not suitable for seizmic restraint; please refer to local professionals who
specialize in seizmic restraint.
When mounting or securing American Standard 1 - 6 ton condensing units and heat pumps
please observe the following:
1. Anytime the unit is to be supported from the edge, the supporting material shall
extend a minimum of two inches under the perimeter of the unit’s base.
2. The mounting hole locations are molded in the basepan, however, they must be
drilled.
a) Hole locations are identified on page 6.
b) Hole diameter is 5/16”.
3. Washers should be placed in between the fastener head and the basepan.
4. American Standard recommends supporting the center of the unit.
5. Base 4 pans have four mounting holes.
Refer to the dimension tables for actual unit size.
Please refer to the following illustrations for dimensions and general information.
Drawing for illustration purposes only.

Section III - Minimum Operating Clearances
This section discusses applying a condensing unit / heat pump in installations where there
are space constraints.
These concerns must be addressed:
1. System Operation - Adequate airflow must be provided to the condensing unit / heat
pump in order to enable appropriate heat transfer. If this is accomplished, head
pressure will remain within an effective operating range.
2. System Serviceability - Proper space must be allowed for the HVAC service techni-
cian to properly maintain the condensing unit / heat pump. Furthermore, space must
be allowed for major component change out in the event of a failure. Working space
is determined by the National Electric Code.
3. Space Maintenance - Appropriate area must be allowed in order to maintain the
ground area where the units are positioned to prohibit debris from collecting on the
panels, thus further providing unobstructed airflow to the condensing unit.
4. State, Local Codes, and National Codes shall prevail. Check with the local jurisdic-
tion before installation to assure compliance.
Numerous projects require reduced clearances between outdoor units and adjacent
walls, fences and other units. The obstruction in question is usually one of the following:
1. One or more walls of an adjacent building.
2. Fences or barriers provided to reduce sound transmission or visually screen the
equipment.
3. Other outdoor units in a multi-unit installation.
4. Overhangs
5. A combination of the above.
The prime considerations involved in establishing minimum clearances are:
1. Adequate airflow to the outdoor coil with minimum recirculation.
2. Service access to the equipment.
3. Compliance with the National Electric Code and other applicable codes.
4. Design temperature - Design temperatures greater than 105°F require additional
consideration.
I. In order to assure that adequate airflow reaches the Allegiance/Heritage 16 condensing
unit, size free air passages at 300 feet per minute (FPM) maximum velocity. See con-
densing unit airflow performance on page 16 of this document; or, for the most current
information, consult the unit’s product data manual.
II. The importance of providing sufficient access for maintenance and service to equip-
ment cannot be overemphasized. The HVAC service technician’s job may be performed
with greater ease and at lower cost if adequate space is allowed.
III. Knowledge of the National Electric Code and other applicable codes for the job site
location is a necessity in order to satisfy local inspectors. These codes are in place for
service as well as safety.
IV. Be sure to read all provisions and footnotes contained in this document. When ambient
temperatures exceed 105°F, more space may be required for minimum operating clear-
ances.

Electrical Code Information
Compliance with Local, State, and National Codes is a must on every HVAC Installation.
This page discusses the criteria regarding minimum working spaces as defined in the 2002
National Electric Code.
The main concern is the safety of the HVAC service / maintenance person. Minimum work-
ing clearances are specified in the National Electric Code (NEC) Article 110.26.
For electrical equipment that from ground to power the voltage is 600 volts or less:
The National Electric Code specifically states that service area around electrical equipment
shall provide sufficient access, and shall be properly maintained in order to permit safe
operation and maintenance of the equipment. Table 110.26(A)(1) as well as the figures
beside the table describe the minimum clearance for proper service and access to electri-
cal equipment.
American Standard residential and light commercial condensing units ranging from 1 to 6
ton require access to the side service panel as indicated on the previous pages to gain
access to the electrical controls.

Condition 2

Note: Where the conditions are as follows
Condition 1 - Exposed live parts on one side and no live or grounded parts
on the other side of the working space, or exposed live parts on both sides
effectively guarded by suitable wood or other insulating materials. Insulated
wire or insulated busbars operating at not over 300 volts to ground shall not
be considered live parts.
Condition 2 - Exposed live parts on one side and grounded parts on the
other side. Concrete, brick, or tile walls shall be considered as grounded.
Condition 3 - Exposed live parts on both sides of the work space (not
guarded as provided in Condition 1) with the operator between.

Example:
Given:
Qty. of 2 units in an area surrounded by a fence on two sides and solid walls on the other
two sides. Units are 4A7A6060A1000A.
Required:
Determine free air opening space required in fence.
Solution:
4300 CFM X Qty. of 2 = 8600 CFM
8600 CFM / 300 FPM = 28.66 square feet
Round 28.66 to 29 square feet of free air opening in the fence sections surrounding the
units. It is recommended to place these opening equally on all four sides, however, if one or
two of the sides are sections of the building structure, it is acceptable to place them on two
sides.

Section IV - Refrigerant Piping
A) Purpose
1) Liquid line - The purpose of the liquid refrigerant line is to convey refrigerant, in the
liquid state, from the outdoor unit to the indoor unit in the cooling mode and from the
indoor unit to the outdoor unit in the heating mode.
2) Gas line - The purpose of the gas line is to convey refrigerant in the gas state and oil
from the indoor unit to the outdoor unit in the cooling mode and from the outdoor
unit to the indoor unit in the heating mode.
B) Limitations:
1) The Allegiance / Heritage 16 utilizes a single unloading scroll type compressor.
Therefore, it is crucial that refrigerant lines are properly sized and do not exceed the
length set forth in the unit’s installation manual.
2) Line length limits:
A. Gas line = 80’ linear length. Of the linear length, 25’ may be installed vertically.
B. Liquid line = 80’ linear length. Of the linear length, 25’ may be installed vertically.
3) No exceptions shall be allowed to these piping limitations.
C) Explanation:
1) Refrigerant lines shall not exceed 80’ total line length. 25’ of the 80’ may be vertical.
2) Liquid subcooling may not be achieved on first stage if the liquid line exceeds 80’ /
25’ vertical.
3) Insufficient oil return during first stage operation if the gas line exceeds 80’ / 25’
vertical.
D) For greater detail regarding refrigerant piping refer to Publication 32-3009-*
