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 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-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 the 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.

3

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 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.

Be extremely careful when using acetylene torch and protect surrounding property.

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 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 damage to the unit and/or minor to serious property damage.

For the best cooling performance and highest energy efficiency

Keep the filter clean

Make sure that your air conditioner is always in top performing condition by cleaning the filter regularly.

Provide good air flow

Make sure the airflow to and from the unit is clear. Your air conditioner puts the conditioned air out at the top of the unit, and takes in unconditioned air at the bottom. Airflow is critical to good operation. It is just as important on the outside of the building that the airflow around the unit exterior is not blocked.

Unit placement

If your air conditioner can be placed in a window or wall that is shaded by a tree or another building, the unit will operate even more efficiently. Using drapes or blinds on the sunny side of the dwelling will also add to your unit’s efficiency.

Insulation

Good insulation will be a big help in maintaining desirable comfort levels. Doors should have weather stripping. Be sure to caulk around doors and windows.

Proper installation of seal gasket

Make sure the seal gasket has been installed properly to minimize noise and improve efficiency. If the seal gasket has not been installed, please refer to the installation instructions.

ELECTRICAL DATA

WARNING

ELECTRIC SHOCK HAZARD

Turn off electric power before service or installation.

All electrical connections and wiring MUST be installedbyaqualifiedelectricianandconformto the National Electrical Code and all local codes

which have jurisdiction.

Failure to do so can result in personal injury or death.

 

NOTICE

 

 

FIRE HAZARD

 

 

Not following the above WARNING could result in fire or

 

 

electically unsafe conditions which could cause moderate

 

 

or serious property damage.

 

 

Read, understand and follow the above warning.

 

 

 

 

Wire Size

Use ONLY wiring size recommended for single outlet branch circuit.

Fuse/Circuit Breaker

Use ONLY the correct HACR type and size fuse/circuit breaker. Read electrical ratings on unit’s

 

rating plate. Proper circuit protection is the responsibiity of the homeowner.

Grounding

Unit MUST be grounded from branch circuit through service cord to unit, or through separate

 

ground wire provided on permanently connected units. Be sure that branch circuit or general

 

purpose outlet is grounded.

Receptacle

The field supplied outlet must match plug on service cord and be within reach of service cord.

 

Do NOT alter the service cord or plug. Do NOT use an extension cord. Refer to the table above

 

for proper receptacle and fuse type.

Theconsumer-throughtheAHAMRoomAirConditionerCertificationProgram-can

 

be certain that the AHAM Certification Seal accurately states the unit’s cooling and

 

heating capacity rating, the amperes and the energy efficiency ratio.
