*Units are rated with 25 ft (7.6 m) of lineset length. See Vapor Line Sizing and Cooling Capacity Loss table when using other sizes and lengths of lineset.NOTE: See un it Installation Instruction for proper installation.
VAPOR LINE SIZI NG AND COOLING CAPACITY LOSS
LONG LINE APPLICATION: An application is considered
”Long line” when the total equivalent tubing length exceeds 80
ft. (24.38 m) or when there is more than 20 ft. (6.09 m) vertical
separation between indoor and outdoor units. These applications
require additional accessories and system modifications for
reliable system operation. The maximum allowable total
equivalent length is up to 250 ft. (76.2 m). The maximum
vertical separation is 200 ft. (60.96 m) when outdoor unit is
above indoor unit, and up to 80 ft. (24.38 m) when the outdoor
unit is below the indoor unit. Refer to Accessory Usage Guideline
below for required accessories. See Longline Application
Guideline for required piping and system modifications. Also,
refer to the table below for the vapor tube diameters based on the
total length to minimize the cooling capacity loss.

Accessory Description and Usage (Listed Alphabetically)
1. Ball--Bearing Fan Motor
A fan motor with ball bearings which permits speed reduction
while maintaining bearing lubrication.
Usage Guideline:
Required on all units when MotorMasterr —
2. 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.
3. Compressor Start Assist — PTC Type
Solid state electrical device which gives a ”soft” boost to the
compressor at each start--up.
Usage Guideline:
Suggested in installations with marginal power supply.
4. 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.
5. Cycle Protector
The cycle protector is designed to prevent compressor short
cycling. This control provides an approximate 5--minute delay
after power to the compressor has been interrupted for any
reason, including power outage, protector control trip, thermostat
jiggling, or normal cycling.
6. Evaporator Freeze Thermostat
An SPST temperature--actuated switch that stops unit operation
when evaporator reaches freeze--up conditions.
Usage Guideline:
Required when low ambient kit has been added.
7. Low--Ambient Pressure Switch Kit
A long life pressure switch which is mounted to outdoor unit
service valve. It is designed to cycle the outdoor fan motor in
order to maintain head pressure within normal operating limits
(approximately 100 psig/689.5 KpA to 225 psig/1551.3 KpA.
The control will maintain working head pressure at low--ambient
temperatures down to 0_F ( --17.8_C) when properly installed.
Usage Guideline:
A Low--Ambient Pressure Switch or MotorMasterr
Low--Ambient Controller must be used when cooling operation is
used at outdoor temperatures below 55_F (12.8_C).
8. MotorMasterr Low--Ambient Controller
A fan--speed control device activated by a temperature sensor,
designed to control condenser fan motor speed in response to the
saturated, condensing temperature during operation in cooling
mode only. For outdoor temperatures down to --20_F (--28.9_C),
it maintains condensing temperature at 100_F ±10_F (37.8_C ±
6.5_C).
Usage Guideline:
A MotorMasterr Low Ambient Controller or
Low--Ambient Pressure Switch must be used when
cooling operation is used at outdoor temperatures
below 55_F (12.8_C).
Suggested for all commercial applications.
9. 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.

Accessory Description and Usage (Listed Alphabetically) (Continued)
10. Sound Hood
Wraparound sound reducing cover for the compressor. Reduces
the sound level by about 2 dBA.
Usage Guideline:
Suggested when unit is installed closer than 15 ft (4.57 m) to
quiet areas, bedrooms, etc.
Suggested when unit is installed between two houses less
than 10 ft (3.05 m) apart.
11. Support Feet
Four stick-- on plastic feet that raise the unit 4 in. (101.6 mm)
above the mounting pad. This allows sand, dirt, and other debris
to be flushed from the unit base, minimizing corrosion.
Usage Guideline:
Suggested in the following applications:
Coastal installations.
Windy areas or where debris is normally circulating.
Rooftop installations.
For improved sound ratings.
165A
12. Thermostatic Expansion Valve (TXV)
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.
Kit includes valve, adapter tubes, and external equalizer tube.
Hard shut off types are available.
NOTE: When using a hard shut off TXV with single phase
reciprocating compressors, a Compressor Start Assist Capacitor
and Relay is required.
Usage Guideline:
Required to achieve ARI ratings in certain equipment
combinations. Refer to combination ratings.
Hard shut off TXV or LLS required in air conditioner
long line applications.
Required for use on all zoning systems.
13. Time-- Delay Relay
An SPST delay relay which briefly continues operation of indoor
blower motor to provide additional cooling after the compressor
cycles off.
NOTE: Most indoor unit controls include this feature. For those
that do not, use the guideline below.
14. Winter Start Control
This control is designed to alleviate nuisance opening of the
low--pressure switch by bypassing it for the first 3 minutes of
operation.
Usage Guideline:
For improved efficiency ratings for certain
combinations of indoor and outdoor units. Refer to
ARI Unitary Directory.
