Step 3 — Complete Refrigerant Piping
GENERAL — All field leak and pressure testing should be in
accordance with local code requirements. If no local code
exists, follow American National Standards Institute (ANSI)/
American Society of Heating, Refrigeration and Air Condi-
tioning Engineers (ASHRAE) Safety Standard 15, latest
revision.
For leak testing procedures, refer to the Carrier Refrigerant
Service Techniques Manual.
COIL CIRCUITING CONVERSION INSTRUCTIONS —
See Table 2 for standard unit circuiting and for the circuiting
available by installing the supplied parts kits. Note that for
044 size units, all circuiting must be field installed using field
supplied parts. Field supplied and installed parts are also
required for 100% circuiting of all 020-034 size units.
The following sections describe how to modify the standard
unit circuiting (as shipped from the factory) for optional splits.
NOTE: All coils are purged with dry air and then capped prior
to shipment. The coils DO NOT contain a refrigerant holding
charge.
