Carrier 25VNA4 PRODUCT DATA

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.

Quality ISO 9001

This product has been designed and manufactured to meet Energy Star criteria for energy eciency when matched with appropriate coil components. However, proper refrigerant charge and proper air ow are critical to achieve rated capacity and eciency. Installation of this product should follow all manufacturing refrigerant charging and air ow instructions. Failure to conrm

proper charge and air ow may reduce energy eciency 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.
