Correct an undercharged system by adding
refrigerant to the system to reduce superheat
and raise sub-cooling.
If the sub-cooling is correct and the
superheat is too high, the TXV may need
adjustment to correct the superheat.
Elevation Limitations
See CB Series Installation, Operation, and
Maintenance manual for rise and run
limitations. All lengths listed are in
equivalent feet. An equivalent foot of the
line includes the pressure drop of all valves,
components, fittings and other pipes in the
sections.
Evaporator Coil
The indoor coil is pressurized. The copper
caps must be punctured to permit a gradual
escape of the pressure prior to unsweating
those caps. Immediately couple the tubing to
the indoor unit to avoid exposing the coils to
moisture. A properly sized filter drier is
furnished in the condenser. When making
solder connections, make sure dry nitrogen
flows through the lines, when heating the
copper, to prevent oxidization inside of the
copper.
Evaporator coils are shipped under
high pressure. Use extreme care and
follow the installation instructions
provided with the evaporator coil to
avoid personal injury.
