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
286BNC
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
the heating mode. See Long Line Guideline.
4. 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.
Note: Snow stand does not support 26” X 26” (660 X 660 mm)
small basepan size.
5. 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.
