IMPORTANT SAFETY INFORMATION

Th e inf or m a ti on co nt ain ed i n thi s ma nua l is inten de d fo r use by a qua l if i ed ser vi c e

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 unqualiﬁ ed persons can result in subjecting the unqualiﬁ 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.

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 qualiﬁ 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.

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, understand and obey

all safety messages.

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.

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:

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.

A message to alert you of potential property damage will have the word “NOTICE”.

Potential property damage can occur if instructions are not followed.

WARNING

CAUTION

NOTICE

• 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 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 REPAIR 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 the 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.

6

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 speciﬁ 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 ﬁ 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 sufﬁ 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.
