Shown in Figure 7 is the correct fan blade setting 
dimension for proper air delivery across the outdoor coil.

Any service work requiring removal or adjustment in 
the fan and/or motor area will require that the dimension

REFRIGERANT CHARGE

This unit was charged at the factory with the quantity of 
refrigerant listed on the serial plate.  AHRI capacity and 

efficiency ratings were determined by testing with this 

refrigerant charge quantity.

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.
