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. 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 is used.
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 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. 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.
4. 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.
5. 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.
6. 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 to
225 psig). The control will maintain working head pressure at
low-ambient temperatures down to 0_F (-18_C) when properly installed
and also using wind baffles. Instructions provided in accessory kit.
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).
7. 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 0°F/–17.8°C), it maintains condensing
temperature at 100_F ±10_F (37.8_C ±5.5_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.
8. Outdoor Air Temperature Sensor
This device enables the thermostat to display the outdoor temperature.
This device is also required to enable special thermostat features such as
auxiliary heat lock out.
Usage Guideline:
Suggested for use with compatible Carrier thermostats.
9. Sound Hood
Wraparound sound reducing cover for the compressor. Reduces the
sound level of the compressor.
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 m) apart.

25SCA5: Product Data
Accessory Description and Usage (Listed Alphabetically) Continued
10. Support Feet
Four or five 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.
11. 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.
Usage Guideline:
Required to achieve AHRI 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.
12. 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.
Usage Guideline:
For improved efficiency ratings for certain combinations of indoor
and outdoor units. Refer to AHRI Directory of Certified Product
Performance (AHRI Directory).
When a Time-Delay Relay (TDR) is called for in the AHRI Directory,
use a 30 second TDR for MicroChannel Indoor units and use a 90
second TDR for Round Tube Plate Fin Indoor units.
13. 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.
Manufacturer reserves the right to change, at any time, specifications and designs without notice and without obligations.

#Detailed cooling capacities are based on indoor and outdoor unit at the same elevation per AHRI standard 210/240-2008. If additional tubing length and/or indoor unit is located above outdoor unit, a slight variation in capacity may occur.
}Sensible capacities shown are based on 80_F (27_C) entering air at the indoor coil. For sensible capacities at other than 80_F (27_C), deduct 835 Btuh (245 kW) per 1000 CFM (480 L/S) of indoor coil air for each degree below 80_F (27_C), or add 835 Btuh
(245 kW) per 1000 CFM (480 L/S) of indoor coil air per degree above 80_F (27_C).
**Total System. kw is total of indoor and outdoor unit kilowatts.
{{At TVA rating indoor condition (75_F edb/63_F ewb). All other indoor air temperatures are at 80_F edb.
NOTE: When the required data falls between the published data, interpolation may be performed. Extrapolation is not an acceptable practice.

25SCA5: Product Data
System Design Summary
1. Intended for outdoor installation with free air inlet and outlet. Outdoor fan external static pressure available is less than 0.01-in. wc.
2. Minimum outdoor operating air temperature without low-ambient operation accessory is 55_F (12.8_C).
3. Maximum outdoor operating air temperature for cooling mode is 125_F (51.7_C).
4. Minimum outdoor operating air temperature for heating mode is –10_F (–23.3_C).
5. Maximum outdoor operating air temperature for heating mode is 66_F (18.9_C).
6. For reliable operation, unit should be level in all horizontal planes.
7. For interconnecting refrigerant tube lengths greater than 80 ft (23.4 m) and/or elevation differences between indoor and outdoor units greater than
20 ft (6.1 m), consult Residential Piping and Longline Guideline and Service Manual available from equipment distributor.
8. If any refrigerant tubing is buried, provide a 6 in. (152.4 mm) vertical rise to the valve connections at the unit. Refrigerant tubing lengths up to 36
in. (914.4 mm) may be buried without further consideration. Do not bury refrigerant lines longer than 36 in. (914.4 mm).
9. Use only copper wire for electric connection at unit. Aluminum and clad aluminum are not acceptable for the type of connector provided.
10. Do not apply capillary tube indoor coils to these units.
