*Fan motor with ball bearings required.
† Start assist capacitor and relay required when using liquid solenoid valve or hard shutoff TXV (except 036 and 042, Series 30; 048, 060 Series 30,
31 single phase; and all 3-phase units). Do not use hard shutoff TXV with liquid solenoid valve.
N/A — Not Applicable
Accessory usage guideline
* For tubing line sets between 50 and 175 ft, refer to Residential’s Split Systems Long-Line Application Guideline.
† Only when low-pressure switch is used.
‡ Required for Low-Ambient Controller (full modulation feature) and 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.
SUGGESTED USE: Required on all units where Low-Ambient Controller (full modulation feature) or MotorMaster® Control has been added.
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.
SUGGESTED USE: In geographic areas where salt damage could occur.
3. Compressor Start Assist — Capacitor and Relay
Start capacitor and start relay gives ‘‘hard’’ boost to compressor motor at each start-up.
SUGGESTED USE: Installations where interconnecting tube length exceeds 50 ft.
Installations where outdoor design temperature exceeds 105°F (40.6°C).
Replacement installations with hard shutoff expansion valve on indoor coil.
Installations where Liquid-Line Solenoid Valve has been added.
4. Compressor Start Assist — PTC
Solid-state electrical device which gives a ‘‘soft’’ boost to the compressor at each start-up.
SUGGESTED USE: Installations with marginal power supply.
Replacement installations with rapid pressure balance (RPB) expansion valve on indoor coil.
5. 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 chance of refrigerant slugging. May or may not include a thermostat control.
SUGGESTED USE: When interconnecting tube length exceeds 50 ft.
When unit will be operated below 55°F (12.8°C) outdoor air temperature. (Use with low-ambient controller.)
All commercial installations.
