Bryant 650A - Product Specifications; Electrical and Compressor Details

Manual for Residential Split-System Air Conditioners and Heat
Pumps Using Puron Refrigerant to minimize losses. Refer to Table
1 for field tubing diameters. Refer to Table 2 for accessory
requirements.
Refrigerant tubes and indoor coil must be evacuated to 500
microns to minimize contamination and moisture in the system.
A. Outdoor Unit Connected to Factory-Approved
Indoor Unit
These outdoor units are carefully evaluated and listed with specific
indoor coils for proper system performance.
IMPORTANT: Do not apply indoor coils which are not factory
approved to these units.
B. Install Adapter Tube
1. Remove plastic retainer holding outdoor piston in liquid
service valve.
2. Check outdoor piston size with matching number listed on
unit rating plate.
3. Locate plastic bag taped to unit containing adapter tube.
4. Remove teflon washer from bag and install on open end of
liquid service valve. (See Fig. 8.)
5. Remove adapter tube from bag and connect threaded nut to
liquid service valve. Tighten nut finger tight and then with
