Your safety and the safety of others is 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:
Indicates a hazard which, if not avoided, can result in severe personal
injury or death and damage to product or other property.
Indicates a hazard which, if not avoided, can result in personal injury
and damage to product or other property.
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.
Indicates property damage can occur if instructions are not followed.
WARNING
Refrigeration system
under high pressure
Do not puncture, heat, expose to ame or
incinerate.
Only certied refrigeration technicians
should service this equipment.
R410A systems operate at higher pressures
than R22 equipment. Appropriate safe ser-
vice and handling practices must be used.
Only use gauge sets designed for use with
R410A.
Do not use standard R22 gauge sets.
NOTICE
CAUTION
WARNING
The information in this manual is intended for use by a qualied 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 unqualied persons can result in subjecting the unqualied 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.

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 qualied 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.
• Do not spray water on the air conditioning unit while the power is on.
• 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.
• Use air conditioner on a single dedicated circuit within the specied amperage rating.
• Use on a properly grounded outlet only.
• Do not cut or modify the power supply cord or remove the ground prong of the plug.
• Never operate the unit on an extension cord.
• Follow all safety precautions and use proper and adequate protective safety aids such as: gloves, goggles,
clothing, properly 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 REPAIR HAZARDS:
• Use approved standard refrigerant recovering procedures and equipment to relieve high 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 ame or hot surfaces
can cause serious burns.
• Make certain to protect personal and surrounding property with re proof materials and have a re extinguisher
at hand while using a torch.
• Provide adequate ventilation to vent off toxic fumes, and work with a qualied assistant whenever possible.
• Always use a pressure regulator when using dry nitrogen to test the sealed refrigeration system for leaks,
ushing etc.
• 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 the sleeve, chassis, and other unit
components especially the sharp 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.
• PROPERTY DAMAGE HAZARDS
• FIRE DAMAGE HAZARDS:
• Read the Installation/Operation Manual for the air conditioning unit prior to operating.
• Use air conditioner on a single dedicated circuit within the specied 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.
• Be extremely careful when using acetylene torch and protect surrounding property.
• Failure to follow these instructions can result in re and minor to serious property damage.
• WATER DAMAGE HAZARDS:
• Improper installation, maintenance or servicing of the air conditioner unit can result in water damage to personal
items or property.
• Insure that the unit has a sufcient 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 damage to the unit and/or minor to serious property damage.
