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)
- 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 using MotorMaster®.
- 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.
- Compressor Start Assist - PTC Type: Solid state electrical device which gives a soft boost to the compressor at each start-up. Usage Guideline: Suggested for single phase unit installations with marginal power supply.
- 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.
- 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.
- Isolation Relay: An SPDT relay which switches the low-ambient controller out of the outdoor fan motor circuit when the heat pump switches to heating mode. Usage Guideline: Required in all heat pumps where low ambient kit has been added.
- 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 the heating mode. See Long Line Guideline.
- 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. The control will maintain working head pressure at low-ambient temperatures down to 0°F (-18°C) when properly installed. Usage Guideline: A Low-Ambient Pressure Switch or MotorMaster® Low-Ambient Controller must be used when cooling operation is used at outdoor temperatures below 55°F (12.8°C).
- MotorMaster® 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 MotorMaster® 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.
- Outdoor Air Temperature Sensor: Designed for use with Carrier 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 Carrier thermostats listed in this publication.
- 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.
- 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 3-stage operation.
- Snow Stand Rack: 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.
- 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. (4.577 m) to quiet areas, bedrooms, etc. Suggested when unit is installed between two houses less than 10 ft. (3.05 m) apart.
- 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.
- 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: Accessory required to meet AHRI rating, where indoor not equipped.

Clearances
Diagram Description: Diagrams illustrating recommended clearances around the outdoor unit for proper installation and airflow. Clearances are shown for service access, sides, and between multiple units.
Note: Numbers in () = mm
IMPORTANT: When installing multiple units in an alcove, roof well, or partially enclosed area, ensure there is adequate ventilation to prevent re-circulation of discharge air.
Balance Point Worksheet
Diagram Description: A graph titled "BALANCE POINT WORKSHEET" plotting Building Heat Loss and Unit Integrated Heating Capacity (MBTUH) against Outdoor Temperature (°F and °C). Several curves represent different model numbers (e.g., 25HCE460, 25HCE448, etc.), showing their heating capacity at various outdoor temperatures. The graph is based on indoor entering air at 70°F (21.1°C) and at rated CFM.

System Design Summary
- Intended for outdoor installation with free air inlet and outlet. Outdoor fan external static pressure available is less than 0.01-in. wc.
- Minimum outdoor operating air temperature without low-ambient operation accessory is 55°F (12.8°C).
- Maximum outdoor operating air temperature for cooling mode is 125°F (51.7°C).
- Minimum outdoor operating air temperature for heating mode is –10°F (–23.3°C).
- Maximum outdoor operating air temperature for heating mode is 66°F (18.9°C).
- For reliable operation, unit should be level in all horizontal planes.
- 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.
- 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).
- Use only copper wire for electric connection at unit. Aluminum and clad aluminum are not acceptable for the type of connector provided.
- Do not apply capillary tube indoor coils to these units.
- Factory-supplied filter drier must be installed.
