Charge Verification - Goodman CONDENSING UNIT Installation & Service Reference

90 minutes. This setting should be adjusted at this time if
needed. The defrost control also has SmartShift™
technology, which delays compressor operation at defrost
initiation and termination. If disabling this function is
desired, move the jumper from "DLY" to "NORM" on the
defrost control
Adequate refrigerant charge for a matching evaporator and 15
feet lineset is supplied with the condensing unit. If line set
exceeds 15 feet in length, refrigerant should be added at .6
ounces per foot of liquid line.
Open the suction service valve first! If the liquid service valve is
opened first, oil from the compressor may be drawn into the
indoor coil TXV, restricting refrigerant flow and affecting opera-
tion of the system.
CAUTION
POSSIBLE REFRIGERANT LEAK
To avoid a possible refrigerant leak, open the service
valves until the top of the stem is 1/8" from the retainer.
When opening valves with retainers, open each valve only until
the top of the stem is 1/8" from the retainer. To avoid loss of
refrigerant, DO NOT apply pressure to the retainer. When open-
ing valves without a retainer remove service valve cap and in-
sert a hex wrench into the valve stem and back out the stem
by turning the hex wrench counterclockwise. Open the valve
until it contacts the rolled lip of the valve body.
NOTE: These are not back-seating valves. It is not necessary
to force the stem tightly against the rolled lip.
After the refrigerant charge has bled into the system, open the
liquid service valve. The service valve cap is the secondary
seal for the valve and must be properly tightened to prevent
leaks. Make sure cap is clean and apply refrigerant oil to threads
and sealing surface on inside of cap. Tighten cap finger-tight

and then tighten additional 1/6 of a turn (1 wrench flat), or to
the following specification, to properly seat the sealing sur-
faces.
1. 3/8" valve to 5 - 10 in-lbs
2. 5/8" valve to 5 - 20 in-lbs
3. 3/4" valve to 5 - 20 in-lbs
4. 7/8" valve to 5 - 20 in-lbs
Do not introduce liquid refrigerant from the cylinder into the
crankcase of the compressor as this may damage the
compressor.
1. Break vacuum by fully opening liquid and suction base
valves.
2. Set thermostat to call for cooling. Check indoor and out-
door fan operation and allow system to stabilize for 10
minutes for fixed orifices and 20 minutes for expansion
valves.

Charge Verification

WARNING
REFRIGERANT UNDER PRESSURE!
• Do not overcharge system with refrigerant.
• Do not operate unit in a vacuum or at negative pres-
sure.
Failure to follow proper procedures may cause
property damage, personal injury or death.
CAUTION
Use refrigerant certified to
refrigerant may cause compressor damage. Most portable
machines cannot clean used refrigerant to meet
standards.
