Section I - Off Season Cooling Operation

American Standard Allegiance / Heritage cooling units and heat pumps may be operated in the coolingmode to 45oF as shipped from the factory. In general, all units that utilize refrigerant HFCF-22 areapproved for use with head pressure control. Units that utilize refrigerant HFC-410A are not approved foroperation with head pressure control.

Please refer to the table on the following page when determining if the unit will operate at the specifiedconditions as well as required accessories.

Compressor Hard Start Kits: BAYKSKT

Windshields:Windshields may be required, please refer to page 17 of this document for information regarding theinstallation of wind barriers. For all applications where cooling operation @ 0F outdoor ambient isspecified, windshields are required in order to prohibit cross winds from affecting operation. In applicationswhere cooling operation is required above 30F, windshields are not a requirement unless the unit is placed inan area where cross winds are prevalent.

Head Pressure Controller: BAYLOAMBAYLOAM103: Approved for heat pumps and cooling units

More Information:As noted in the table on the following page, American Standard Allegiance cooling units and Heritage heatpump units may be operated in the cooling mode to 0oF if necessary, by applying the BAYLOAM103 headpressure controller and other required accessories. The BAYLOAM103 is a newly developed head pres-sure controller that cycles the OD fan as needed to maintain liquid line temperature as set by the DIPswitches located on the control. There is no need to change the outdoor fan motor on approved productssince the controller does not vary the frequency to the motor. For more information please refer to publica-tion number 18-HE46D1-1or latest version.

SECTION II - Unit Mounting:This section describes appropriate methods for mounting and securing Allegiance cooling units and Heritageheat pump units. However, if these units are to be mounted in a region where seizmic loads or high windsare an issue, please refer to the American Standard BAYECMT001 extreme conditions mounting kitinstallation instructions publication Number #18-HE44D1-* (* latest verstion )

When mounting or securing American Standard 1 - 6 ton condensing units and heat pumps please observethe following.

1. Anytime the unit is to be supported from the edge, the supporting material shall extend minimum twoinches under the perimeter of the unit’s base.

2. The mounting hole locations are molded in the basepan, however, they must be drilled through.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.

Section III - Minimum Operating Clearances

This section discusses applying a condensing unit / heat pump in installations where there are spaceconstraints. The reduced clearances described in this document are for operation purposes only.Local Codes prevail for servicing and sefety.

These concerns must be addressed:1. System Operation - Adequate airflow must be provided to the condensing unit / heat pump in orderto enable appropriate heat transfer. If this is accomplished, head pressure will remain within an effectiveoperating range.2. System Servicability - Proper space must be allowed for the HVAC service technician to properlymaintain the condensing unit / heat pump. Furthermore, space must be allowed for majorcomponent change out in the event of a failure. Working space is determined by the National ElectricCode3. Space Maintenance - Appropriate area must be allowed in order maintain the ground area where theunits are positioned to prohibit debris from collecting on the panels, thus further providing unobstructedairflow to the condensing unit.4. State, Local Codes, and National Codes shall prevail. Check with the local jurisdiction beforeinstallation to assure compliance.

Numerous projects require reduced clearances between outdoor units and adjacent walls, fences and otherunits. 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. Overhangs5. 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 105F require additional consideration.

I. In order to assure that adequate airflow reaches the Allegiance 18 condensing unit, size free air passagesat 300 feet per minute maximum velocity (FPM). See condensing unit airflow performance on page 16 ofthis 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 equipment cannot beoveremphasized. The HVAC service technician’s job may be performed with greater ease and at lower costif adequate space is allowed.

III. Knowledge of the National Electric Code and other applicable codes for the job sight location is anecessity 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 temperaturesexceed 105F, more space may be required for minimum operating clearances.

Electrical Code Information

Compliance with Local, State, and National Codes is a must on every HVAC Installation. This pagediscusses 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 working clearancesare 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 providesufficient access, and shall be properly maintained in order to permit safe operation and maintenance of theequipment. Table 110.26 as well as the figures beside the table describe the minimum clearance for properservice and access to electrical equipment.

American Standard residential and light commercial condensing units ranging from 1 to 6 ton require accessto the side service panel as indicated on the previous pages to gain access to the electrical controls.

Condition 1(3 ft min. for 151 - 600 V)

Condition 2(Space would increase to 3 1/2 ft for 151 - 600 V)
