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.
