Goodman Mfg 000 &12, MSC/MSH 9, 000 BTUH + 115 Volt Safe Refrigerant Handling, Safety Check

•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.)

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.

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.

•Securely tighten the valve stem cap with a spanner or similar tool.

•See tightening torque table in Tightening Connection section.

Safety Check

After completing the electrical installation:

1.Grounding: After grounding the unit, measure the ground- ing resistance by visually inspecting the unit and by us- ing a grounding resistance tester, making sure the ground- ing resistance is less than 4.0 ohms.

2.Electrical leakage check (to be performed during opera- tion): During the test operation after complete installation of the unit, the qualified installer may use the electroprobe and multimeter to perform the electrical leakage check. Turn off the unit immediately if leakage occurs.
