charge indicated on Heat Pump nameplate (remember to also
add any charge required for line set differences from 15 feet).
SN indicates serial number.

IMPORTANT
Use table 6 as a general guide when performing maintenance checks. This is not a procedure for charging the unit (Refer
to Charging / Checking Charge section). Minor variations in these pressures may be expected due to differences in
installations. Significant differences could mean that the system is not properly charged or that a problem exists with some
component in the system.

*These are most−popular−match−up pressures. Indoor match up, indoor air quality, and indoor load cause pressures to vary.
**Temperature of the air entering the outside coil (outdoor ambient temperature).
