IMPORTANT SAFETY INFORMATION

The information contained in this manual is intended for use by a qualified service technician who is familiar with the safety procedures required for installation and repair, and who is equipped with the proper tools and test instruments required to service this product.

Installation or repairs made by unqualified persons can result in subjecting the unqualified person making such repairs as well as the persons being served by the equipment to hazards resulting in injury or electrical shock which can be serious or even fatal.

Safety warnings have been placed throughout this manual to alert you to potential hazards that may be encountered. If you install or perform service on equipment, it is your responsibility to read and obey these warnings to guard against any bodily injury or property damage which may result to you or others.

Your safety and the safety of others are very important.

We have provided many important safety messages in this manual and on your appliance. Always read and obey all safety messages.

This is a Safety Alert symbol.

This symbol alerts you to potential hazards that can kill or hurt you and others.

All safety messages will follow the safety alert symbol with the word “WARNING” or “CAUTION”. These words mean:

WARNING

CAUTION

You can be killed or seriously injured if you do not follow instructions.

You can receive minor or moderate injury if you do not follow instructions.

All safety messages will tell you what the potential hazard is, tell you how to reduce the chance of injury, and tell you what will happen if the instructions are not followed.

A message to alert you of potential property damage will have the NOTICE word “NOTICE”. Potential property damage can occur if instructions

are not followed.

PERSONAL INJURY OR DEATH HAZARDS

ELECTRICAL HAZARDS:

Unplug and/or disconnect all electrical power to the unit before performing inspections, maintenance, or service.

Make sure to follow proper lockout/tag out procedures.

Always work in the company of a qualified assistant if possible.

Capacitors, even when disconnected from the electrical power source, retain an electrical charge potential capable of causing electric shock or electrocution.

Handle, discharge, and test capacitors according to safe, established, standards, and approved procedures.

Extreme care, proper judgment, and safety procedures must be exercised if it becomes necessary to test or troubleshoot equipment with the power on to the unit.

2

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 specified amperage rating.

Use on a properly grounded outlet only.

Do not remove ground prong of plug.

Do not cut or modify the power supply cord.

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-acetylenetorch. Direct contact with the torch’s flame or hot surfaces can cause serious burns.

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

Have a fire extinguisher at hand while using a torch.

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

Always use a pressure regulator when using dry nitrogen to test the sealed refrigeration system for leaks, flushing 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 fins 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.

PROPERTY DAMAGE HAZARDS

FIRE DAMAGE HAZARDS:

Read the Installation/Operation Manual for this air conditioning unit prior to operating.

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

Connect to a properly grounded outlet only.

Do not remove ground prong of plug.

Do not cut or modify the power supply cord.

Do not use extension cords with the unit.

Failure to follow these instructions can result in fire and minor to serious property damage.

WATER DAMAGE HAZARDS:

Improper installation maintenance, or servicing of the air conditioner unit, or not following the above Safety Warnings can result in water damage to personal items or property.

Insure that the unit has a sufficient pitch to the outside to allow water to drain from the unit.

Do not drill holes in the bottom of the drain pan or the underside of the unit.

Failure to follow these instructions can result in result in damage to the unit and/or minor to serious property damage.
