Do not spray or pour water on the return air grille, discharge air grille, evaporator coil, control panel, and sleeve on the room side of the air conditioning unit while cleaning.

Electrical component malfunction caused by water could result in electric shock or other electrically unsafe conditions when the power is restored and the unit is turned on, even after the exterior is dry.

Never operate the A/C unit with wet hands.

Use air conditioner on a single dedicated circuit within the specifi ed amperage rating.

Use on a properly grounded electrical circuit only.

Do not use extension cords with the unit.

Follow all safety precautions and use proper and adequate protective safety aids such as: gloves, goggles, clothing, adequately insulated tools, and testing equipment etc.

Failure to follow proper safety procedures and/or these warnings can result in serious injury or death.

REFRIGERATION SYSTEM HAZARDS:

Use approved standard refrigerant recovering procedures and equipment to relieve pressure before opening system for repair.

Do not allow liquid refrigerant to contact skin. Direct contact with liquid refrigerant can result in minor to moderate injury.

Be extremely careful when using an oxy-acetylene torch. Direct contact with the torch’s fl ame or hot surfaces can cause serious burns.

Make sure to protect personal and surrounding property with fi re proof materials.

Have a fi re extinguisher at hand while using a torch.

Provide adequate ventilation to vent off toxic fumes, and work with a qualifi ed assistant whenever possible.

Always use a pressure regulator when using dry nitrogen to test the sealed refrigeration system for leaks, fl ushing etc.

Make sure to follow all safety precautions and to use proper protective safety aids such as: gloves, safety glasses, clothing etc.

Failure to follow proper safety procedures and/or these warnings can result in serious injury or death.

MECHANICAL HAZARDS:

Extreme care, proper judgment and all safety procedures must be followed when testing, troubleshooting, handling, or working around unit with moving and/or rotating parts.

Be careful when, handling and working around exposed edges and corners of sleeve, chassis, and other unit components especially the sharp fi ns of the indoor and outdoor coils.

Use proper and adequate protective aids such as: gloves, clothing, safety glasses etc.

Failure to follow proper safety procedures and/or these warnings can result in serious injury or death.
