25VNA4
INFINITY®
VARIABLE SPEED HEAT PUMP
WITH GREENSPEED™ INTELLIGENCE
2 TO 5 NOMINAL TONS
PRODUCT DATA
Carrier’s 25VNA4 with Greenspeed™ Intelligence is a breakthrough
product providing up to 13 HSPF heating efficiency and up to 24 SEER
cooling efficiency. The variable speed capacity control results in strong
heating capacity as the outdoor temperature drops resulting in less
reliance on auxiliary heat. Lower speed operation, when needed in
cooling, for enhanced comfort and dehumidification.
This product has been designed and manufactured to meet Energy Star®
criteria for energy efficiency when matched with appropriate coil
components. Refer to the combination ratings in this Product Data for
system combinations that meet Energy Star guidlines.
NOTE: Ratings contained in this document are subject to change at any
time. Always refer to the AHRI directory (www.ahridirectory.org) for
the most up-to-date ratings information.

This product has been designed and manufactured to
meet Energy Star criteria for energy eciency when
matched with appropriate coil components. However,
proper refrigerant charge and proper air ow are critical
to achieve rated capacity and eciency. Installation of
this product should follow all manufacturing refrigerant
charging and air ow instructions. Failure to conrm
proper charge and air ow may reduce energy
eciency and shorten equipment life.

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:

MIN/MAX Airflow tables
The indoor airflow delivered by this system varies significantly based on outdoor temperature, indoor unit combination, and system demand. The
airflows on these tables are for duct design considerations.
Duct systems capable of these ranges will ensure the system will deliver full capacity at all outdoor temperatures.
Minimum and maximum airflows can be adjusted from these numbers in the Infinity Control Heat Pump Setup screen.

Accessory Description and Usage (Listed Alphabetically)
1. Compressor Start Assist
The inverter drive gently starts the variable speed compressor at all times. No other start device is compatible with this unit.
2. Crankcase Heater
This unit has a compressor crankcase heater that will be energized to prevent the compressor from being the coldest part of the system thus enhancing
reliability. the indoor unit and UI do not need to be installed for the crankcase heater to operate properly..
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 OFF mode.
Usage Guideline:
An LLS is required in all long line applications to control refrigerant off cycle migration in the OFF mode. See Long Line Guideline.
Suggested for all commercial applications.
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:
- Unit installations in heavy snowfall areas.
- Unit installations in snow drift locations.
- Unit installations in areas of prolonged subfreezing temperatures.
- All commercial installations.
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.
