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.
Usage Guideline:
Required when low ambient kit has been added.
7. High Pressure Switch
A high pressure switch that protects unit against excessive pressure.
Usage Guideline:
Required in all heat pumps operated in dual fuel
applications.
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.
Usage Guideline:
Required in all heat pumps where low ambient kit has
been added.
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.
Usage Guideline:
An LLS is required in all long line heat pump
applications to control refrigerant off cycle migration in
the heating mode. See Long Line Guideline.
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
(--18_C) when properly installed.
Usage Guideline:
A Low -- Ambient Pressure Switch or MotorMasterr
Low--Ambient Controller must be used when cooling
operation is used at outdoor temperatures below 55_F
(12.8_C).

Accessory Description and Usage (Listed Alphabetically) -- CONTINUED
11. MotorMasterr Low--Ambient Controller
A fan--speed control device activated by a temperature sensor,
designed to control condenser fan motor speed in response to the
saturated, condensing temperature during operation in cooling
mode only. For outdoor temperatures down to --20_F (--28.9_C), it
maintains condensing temperature at 100_F ±10_F (37.8_C ±
5.5_C).
Usage Guideline:
A MotorMasterr Low Ambient Controller or
Low--Ambient Pressure Switch must be used when
cooling operation is used at outdoor temperatures
below 55_F (12.8_C).
Suggested for all commercial applications.
12. Outdoor Air Temperature Sensor
Designed for use with Carrier Thermostats listed in this
publication. This device enables the thermostat to display the
outdoor temperature. This device also is required to enable special
thermostat features such as auxiliary heat lock out.
Usage Guideline:
25HCS3C
13. Outdoor Thermostat
An SPDT temperature--actuated switch which turns on
supplemental electric heaters when outdoor air temperature drops
below a user--selected set point.
14. Secondary Outdoor Thermostat
An SPDT temperature--actuated switch which turns on third--stage
of supplemental electric heaters when outdoor air temperature
drops below the second--stage set point.
capable of 3--stage operation.
15. Snow Stand
Coated wire rack which supports unit 18 in. (457.2 mm) above
mounting pad to allow for drainage from unit base.
Suggested for all Carrier thermostats listed in this
publication.
Usage Guideline:
Electric supplemental heat applications in non -- variable
speed indoor units when electric heat staging is desired.
Usage Guideline:
Some local codes may require limiting the heating head
pressure in the vapor line in some applications.
Usage Guideline:
Outdoor thermostat applications where electric heater is
Usage Guideline:
Suggested in the following applications:
Heat pump installations in heavy snowfall areas.
Heat pump installations in snow drift locations.
Heat pump installations in areas of prolonged
subfreezing temperatures.
All commercial installations.
16. Sound Hood
Wraparound sound reducing cover for the compressor. Reduces the
sound level up to 2 dBA.
Usage Guideline:
Suggested when unit is installed closer than 15 ft
(4.57 m) to quiet areas, bedrooms, etc.
Suggested when unit is installed between two houses less
than 10 ft (3.05 m) apart.
Usage Guideline:
Suggested in the following applications:
Heat pump installations in heavy snowfall areas.
Heat pump installations in snowdrift locations.
Heat pump installations in areas of prolonged
subfreezing temperatures.
All commercial installations.
17. 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:
Required in all heat pump applications
18. Time--Delay Relay
An SPST delay relay which briefly continues operation of indoor
blower motor to provide additional cooling after the compressor
cycles off.
