Important Safety Information

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.

Maintenance is the responsibility of the owner. Failure to properly maintain or repair equipment may result in personal injury

and/or various types of property damage (re, ood, etc.).

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.

Due to continuing research in new energy-saving technology, all information in this manual is subject to change without notice.

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

STAGES OF CONSTRUCTION

WARNING

EXPLOSION HAZARD

Please read this manual thoroughly prior to

equipment installation or operation. It is the installers

responsibility to properly apply and install the

equipment. Installation must be in conformance with

the NFPA 70-2008 National Electric Code or current

edition, International Mechanic code 2009 or current

edition and any other applicable local or national

codes.

WARNING

EXPLOSION HAZARD

Refrigeration system under high pressure. Do not

puncture, heat, expose to ﬂame or incinerate. Only

certiﬁed refrigeration technicians should service this

INTRODUCTION

Personal Injury Or Death Hazards

ELECTRICAL HAZARDS:

• Shutdown 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. Wait a few minutes after shutdown to allow the capacitors to discharge the stored energy.

• 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 turned 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.

• Ensure that the unit is properly grounded.

• Follow all safety precautions and use approved protective safety equipment such as: gloves, goggles, and clothing. Ensure

that properly insulated tools, and testing equipment are are used as well to protect against equipment damage and reduce

the risk of injury.

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

• REFRIGERATION SYSTEM REPAIR HAZARDS:

• Use approved standard refrigerant recovering procedures and equipment to relieve high pressure before opening system for

repair. Reference EPA regulations (40 CFR Part 82, Subpart F ) Section 608.

• 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.

• 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.
