This product has been designed and manuf actured to
meet Ener gy Star® criteria for energy efficiency when
matched with appropriate coil components. However,
proper ref rigerant c harge and proper air f low are cri tical
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 a nd shorten equipment life.

** Outdoor temperature sensor is an accessory for all Carrier electronic thermostats, except the non --- programmable air conditioner version and builder;s
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.
{ Th ermostat 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.

Accessory Description and Usage (Listed Alphabetically)
1. Ball--Bearing Fan Motor
A fan motor with ball bearings which permits speed reduction
while maintaining bearing lubrication.
Usage Guideline:
Required on all units when MotorMasterr is used.
2. 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
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.
3. Compressor Start Assist — PTC Type
Solid state electrical device which gives a ”soft” boost to the
compressor at each start--up.
Usage Guideline:
Suggested in installations with marginal power supply.
4. 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.
5. Cycle Protector
The cycle protector is designed to prevent compressor short
cycling. This control provides an approximate 5--minute delay after
power to the compressor has been interrupted for any reason,
including power outage, protector control trip, thermostat jiggling,
or normal cycling.
6. Evaporator Freeze Thermostat
An SPST temperature--actuated switch that stops unit operation
when evaporator reaches freeze--up conditions.
7. High Pressure Switch
A high pressure switch that protects unit against excessive pressure.
8. Isolation Relay
An SPDT relay which switches the low--ambient controller out of
the outdoor fan motor circuit when the heat pump switches to
heating mode.
9. 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.
10. Low-- Ambient Pressure Switch Kit
A long life pressure switch which is mounted to outdoor unit
service valve. It is designed to cycle the outdoor fan motor in order
to maintain head pressure within normal operating limits
(approximately 100 psig to 225 psig). The control will maintain
working head pressure at low--ambient temperatures down to
0_F/--17.78_C when properly installed.
