Safe Refrigerant Handling - Goodman MSC 15 SEER 9,000 BTUH Manual De Instalación Y Funcionamiento

NOTES:
• If the pressure rises to 1000 microns or less and re-
mains steady, the system is considered leak-free; pro-
ceed to start-up.
• If pressure rises above 1000 microns but hold steady
below 2000 microns, moisture and/or non-condensables
may be present or the system may have a small leak.
Return to step 2. If the same result is encountered,
check for leaks as previously indicated and repair as
necessary, then repeat evacuation.
• If pressure rises above 2000 microns, a leak is present.
Check for leaks as previous indicated and repair as nec-
essary then repeat evacuation.

• When relocating the unit to another place, perform the
evacuation using a vacuum pump.
• Refrigerant added to the unit must be in liquid form. (Does
not apply to units using R-22.)

Safe Refrigerant Handling

While these items will not cover every conceivable situation,
they should serve as a useful guide.
WARNING
Refrigerants are heavier than air. They can "push out"
the oxygen in your lungs or in any enclosed space.To
avoid possible difficulty in breathing or death:
• Never purge refrigerant into an enclosed room or
space. By law, all refrigerants must be reclaimed.
• If an indoor leak is suspected, throughly ventilate the
area before beginning work.
• Liquid refrigerant can be very cold. To avoid possible
frostbite or blindness, avoid contact and wear gloves
and goggles. If liquid refrigerant does contact your
skin or eyes, seek medical help immediately.
• Always follow EPA regulations. Never burn refrig-
erant, as poisonous gas will be produced.
WARNING
To avoid possible explosion:
• Never apply flame or steam to a refrigerant cylinder.
If you must heat a cylinder for faster charging,
partially immerse it in warm water.
• Never fill a cylinder more than 80% full of liquid re-
frigerant.
• Never add anything other than R-22 to an R-22 cy-
linder or R-410A to an R-410A cylinder. The service
equipment used must be listed or certified for the
type of refrigerant used.
• Store cylinders in a cool, dry place. Never use a cy-
linder as a platform or a roller.
WARNING
To avoid possible explosion, use only returnable (not
disposable) service cylinders when removing refrig-
erant from a system.
• Ensure the cylinder is free of damage which could
lead to a leak or explosion.
• Ensure the hydrostatic test date does not exceed
5 years.
• Ensure the pressure rating meets or exceeds 400
lbs.
When in doubt, do not use cylinder.
Use caution when handling the packed valve:
• Open the valve stem unit it comes in contact against the
stopper. Do not attempt to open further.
