SAFETY CONSIDERATIONS

Installation and servicing of air-conditioning equipment can be hazardous due to system pressure and electrical compo- nents. Only trained and qualified service personnel should install, repair, or service air-conditioning equipment.

Untrained personnel can perform basic maintenance func- tions of cleaning coils and filters and replacing filters. All other operations should be performed by trained service per- sonnel. When working on air-conditioning equipment, observe precautions in the literature, tags and labels attached to the unit, and other safety precautions that may apply.

Follow all safety codes. Wear safety glasses and work gloves. Use quenching cloth for unbrazing operations. Have fire extin- guishers available for all brazing operations.

WARNING: Before performing service or mainte- nance operations on unit, turn off main power switch to unit and install lockout tag to disconnect switch. Elec- trical shock could cause personal injury.

2.Do not store or use gasoline or other flammable vapors and liquids in the vicinity of this or any other appliance.

What to do if you smell gas:

1.DO NOT try to light any appliance.

2.DO NOT touch any electrical switch, or use any phone in your building.

3. IMMEDIATELY call your gas supplier from a neighbor’s phone. Follow the gas supplier’s instructions.

4.If you cannot reach your gas supplier, call the fire department.

WARNING: Disconnect gas piping from unit when pressure testing at pressure greater than 0.5 psig. Pres- sures greater than 0.5 psig will cause gas valve damage resulting in hazardous condition. If gas valve is subjected to pressure greater than 0.5 psig, it must be replaced before use. When pressure testing field-supplied gas pip- ing at pressures of 0.5 psig or less, a unit connected to such piping must be isolated by closing the manual gas valve(s).

IMPORTANT: Units have high ambient operating limits. If limits are exceeded, the units will automatically lock the com- pressor out of operation. Manual reset will be required to restart the compressor.
