Fixed Orifice

1. Temporarily install the thermometer on the suction (large) line 

near the compressor. The thermometer should be located 
within 4" (10.2 cm) to 6" (15.2 cm) of the compressor. Ensure 
that the thermometer makes adequate contact and is 
insulated.

NOTE: An optional method is to locate the thermometer at the 
suction line service valve. Ensure that the thermometer makes 
adequate contact and is insulated.

2. Refer to the System Superheat chart provided for proper 

system superheat. Add charge to lower superheat or recover 
charge to raise superheat.

Expansion Valve System

Single Speed Application

1. Temporarily install the thermometer on both the liquid (small) 

and vapor (large) lines near the service valves. Ensure that 
there is adequate contact. Insulate the sensors well for the 
best possible reading. Use the liquid temperature to 
determine subcooling and the vapor temperature to 
determine superheat.

2. Check subcooling and superheat. Systems with TXV 

application should have a subcooling of 5ºF to 9ºF and 
superheat of 7ºF to 9 ºF.

If the subcooling and superheat are low, adjust TXV to 7ºF 
to 9ºF superheat. Check subcooling.
NOTE: To adjust the superheat, turn the valve stem 
clockwise to increase and counterclockwise to decrease.

If the subcooling is low and the superheat is high, add 
charge to raise the subcooling to 5ºF to 9ºF. Check 
superheat.

If subcooling and superheat are high, adjust TXV valve to 
7ºF to 9ºF superheat. Check subcooling.

If subcooling is high and superheat is low, adjust TXV 
valve to 7ºF to 9ºF superheat and remove charge to lower 
the subcooling to 5ºF to 9ºF.

NOTE: Do not adjust the charge based on the suction 
pressure unless there is a gross undercharge.

2-Stage Application

1. Temporarily install the thermometer on both the liquid (small) 

and vapor (large) lines near the service valves. Ensure that 
there is adequate contact. Insulate the sensors well for the 
best possible reading. Use the liquid temperature to 
determine subcooling and the vapor temperature to 
determine superheat.

2. Check the subcooling and superheat. Systems with TXV 

application should have a subcooling of 5ºF to 9ºF and 
superheat of 7ºF to 9ºF.

If the subcooling and superheat are low, adjust TXV to 7ºF 
to 9ºF superheat. Check subcooling.
NOTE: To adjust the superheat, turn the valve stem 
clockwise to increase and counterclockwise to decrease.

If the subcooling is low and the superheat is high, add 
charge to raise the subcooling to 5ºF to 9ºF. Check 
superheat.

If subcooling and superheat are high, adjust TXV valve to 
7ºF to 9ºF superheat. Check subcooling.

If subcooling is high and superheat is low, adjust TXV 
valve to 7ºF to 9ºF superheat and remove charge to lower 
the subcooling to 5ºF to 9ºF.

Goodman 30

To prevent personal injury, carefully connect and 
disconnect manifold gauge hoses. Escaping liquid 
refrigerant can cause burns. Do not vent refrigerant into 
the atmosphere. Recover all refrigerant during system 
repair and before final unit disposal.
