*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 unit Installation Instruction for proper installation.
VAPOR LINE SIZING AND COOLING CAPACITY LOSS
Acceptable vapor line diameters provide adequate oil return to the compressor while avoiding excessive capacity loss. The suction line diameters shown in the chart below are acceptable for HP systems with Puron refrigerant:

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 using 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. 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. 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.
7. 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.
8. 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 MotorMasterr Low-Ambient Controller must be used when cooling operation is used at outdoor temperatures below 55_F (12.8_C).
9. 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.
