EVOLUTION™* CONTROLS
* When applied with Bryant’s Perfect Humidity™ series 355, 315 and FE Indoor Models.
† Must be installed in Dual-Fuel Evolution system applications.
ACCESSORY USAGE GUIDELINE
* For tubing line sets greater than 50 ft horizontal and/or 20 ft vertical differential, refer to Residential Split-System Long-Line Application Guideline
and Service Manual.
† Only when low-pressure switch is used.
‡ Required for MotorMaster® Control only.
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 low-ambient controller (full modulation feature) or MotorMaster®—Low-Ambient Controller is installed.
2. 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.
3. 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
Hard shut off expansion valve on indoor coil
Liquid line solenoid on indoor coil
Required for scroll compressors in the following applications:
Long line
Low ambient
Suggested for all compressors in areas with a history of low voltage problems.
4. Compressor Start Assist — PTC Type
Solid state electrical device which gives a "soft" boost to the reciprocating compressor at each start-up.
Usage Guideline:
Suggested in installations with marginal power supply.
