Accessory Description and Usage (Listed Alphabetically)

1. Coastal Filter
A mesh screen inserted under the top cover and inside the base pan to protect the condenser coil from salt damage without restricting airflow.
Usage Guideline:
Suggested in geographic areas where salt damage could occur.
2. Outdoor Air Temperature Sensor
A device that allows the temperature at a remote location (outdoors) to be displayed at the thermostat.
Usage Guideline:
Suggested in all Carrier programmable thermostats.
3. Support Feet
Four stick-on plastic feet that raise the unit 4 in. above the mounting pad. This allows sand, dirt, and other debris to be flushed from the unit base, minimizing
corrosion.
Usage Guideline:
Suggested in the following applications:
Coastal installations.
Windy areas or where debris is normally circulating.
Rooftop installations.
For improved sound ratings.
4. Thermostatic Expansion Valve (TXV)
A modulating, flow-control valve that meters refrigerant liquid flow rate into the evaporator in response to the superheat of the refrigerant gas leaving the evap-
orator. Kit includes valve, adapter tubes, and external equalizer tube.
NOTE: Furnace coils and variable-speed fan coils designed for Puron refrigerant are factory supplied with balanced-port Puron-refrigerant TXV.
Usage Guideline:
A balanced-port TXV specifically designed for Puron refrigerant is required for all installations.

† If wire is applied at ambient greater than 30°C (86°F), consult Table
310-16 of the NEC (ANSI/NFPA 70). The ampacity of nonmetallic-
sheathed cable (NM), trade name ROMEX, shall be that of 60°C
(140°F) conductors, per the NEC (ANSI/NFPA 70) Article 336-26. If
other than uncoated (non-plated), 60 or 75°C (140 or 167°F) insula-
tion, copper wire (solid wire for 10 AWG and smaller, stranded wire
for larger than 10 AWG) is used, consult applicable tables of the NEC
(ANSI/NFPA 70).
‡ Length shown is as measured 1 way along wire path between unit
and service panel for voltage drop not to exceed 2%.
