environmentally sound refrigerant allows consumers to make a
responsible decision in the protection of the earth’s ozone layer.

This product has been designed and manufactured to meet Energy
Starr criteria for energy efficiency when matched with appropriate
coil components. Refer to the combination ratings in the Product
Data for system combinations that meet Energy Starr guidelines.

NOTE: Ratings contained in this document are subject to
change at any time. Always refer to the AHRI directory

LONG LINE APPLICATIONS

An application is considered Long Line when the refrigerant level in the system requires the use of accessories to maintain acceptable
refrigerant management for systems reliability. Defining a system as long line depends on the liquid line diameter, actual length of the tubing,
and vertical separation between the indoor and outdoor units.

For Heat Pump systems, the chart below shows when an application is considered Long Line. Beyond these lengths, long line accessories
are required:

Accessory Description and Usage (Listed Alphabetically)

1. Compressor Start Assist -- Capacitor and Relay

Start capacitor and relay gives a “hard” boost to compressor motor
at each start up.

Usage Guideline:

Required for reciprocating compressors in the following
applications:

Long line
Low ambient cooling
Hard shut off expansion valve on indoor coil
Liquid line solenoid on indoor coil

Required for single--phase scroll compressors in the
following applications:

Long line
Low ambient cooling

Suggested for all compressors in areas with a history of
low voltage problems.

2. Crankcase Heater

An electric resistance heater which mounts to the base of the
compressor to keep the lubricant warm during off cycles. Improves
compressor lubrication on restart and minimizes the chance of
liquid slugging.

Usage Guideline:

Required in low ambient cooling applications.
Required in long line applications.
Suggested in all commercial applications.

3. Liquid--Line Solenoid Valve (LLS)

An electrically operated shutoff valve which stops and starts
refrigerant liquid flow in response to compressor operation. It is to
be installed at the outdoor unit to control refrigerant off cycle
migration in the heating mode.

Usage Guideline:

An LLS is required in all long line heat pump
applications to control refrigerant off cycle migration in

t he heating mode. See Long Line Guideline.

Suggested for all commercial applications.

4. Outdoor Air Temperature Sensor

Designed for use with Bryant Thermostats listed in this
publication. This device enables the thermostat to display the

outdoor temperature. This device also is required to enable special
thermostat features such as auxiliary heat lock out.

Usage Guideline:

Suggested for all Bryant thermostats listed in this
publication.

5. Outdoor Thermostat

An SPDT temperature--actuated switch which turns on
supplemental electric heaters when outdoor air temperature drops
below a user--selected set point.

Usage Guideline:

Electric supplemental heat applications in non--variable
speed indoor units when electric heat staging is desired.

6. Secondary Outdoor Thermostat

An SPDT temperature--actuated switch which turns on third--stage
of supplemental electric heaters when outdoor air temperature
drops below the second--stage set point.

Usage Guideline:

Outdoor thermostat applications where electric heater is
capable of three--stage operation.

7. Snow Stand

Coated wire rack which supports unit 18 in. (457.2 mm) above
mounting pad to allow for drainage from unit base.

Usage Guideline:

Suggested in the following applications:

Heat pump installations in heavy snowfall areas.
Heat pump installations in snow drift locations.
Heat pump installations in areas of prolonged

subfreezing temperatures.
All commercial installations.

8. Thermostatic Expansion Valve (TXV) Bi--Flow

A modulating flow--control valve which meters refrigerant liquid
flow rate into the evaporator in response to the superheat of the
refrigerant gas leaving the evaporator.

Usage Guideline:

Accessory required to meet AHRI rating and system
reliability, where indoor not equipped.

Required in all heat pump applications designed with
Puron refrigerant.
