The following pressure tables show nominal pressures
for the units. Since many installation specific
situations can affect the pressure readings, this
information should only be used by certified
technicians as a guide for evaluating proper system
performance. They shall not be used to adjust charge.
If charge is in doubt, reclaim, evacuate and recharge
the unit to the serial plate charge.
