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

* Outdoor temperature sensor is an accessory for all Carrier electronic thermostats, except the non ---programmable air conditioner version and builders
thermostats. It allows the temperature at a remote location (outdoors) to be displayed on the thermostat. The outdoor air temperature sensor must be used
with the HybridHeatt(dual fuel) thermostat.
{Thermostat conversion kit is a 24---vac accessory that can turn a 4 ---wire thermostat application into a 5 ---wire application. This kit can also be used to
replace a broken thermostat wire, or add an extra wire when needed.
The outdoor air temperature sensor is included with the Thermidistat Control and HybridHeatt(dual fuel) thermostat.
