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

service 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.

This service manual is designed to be used in conjunction with the installation and operation manuals provided

with each air conditioning system.

This service manual was written to assist the professional service technician to quickly and accurately diagnose

and repair malfunctions.

Installation procedures are not given in this manual. They are given in the Installation/Operation manual which

can be aquired on the Friedrich website.

IMPORTANT: It will be necessary for you to accurately identify the unit you are servicing, so you can be certain of

a proper diagnosis and repair.

• 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.

• 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.

WARNING

Electrical Shock Hazard

Make sure your electrical receptacle

has the same conguration as your air

conditioner’s plug. If different, consult

a Licensed Electrician.

Do not use plug adapters.

Do not use an extension cord.

Do not remove ground prong.Always

plug into a grounded 3 prong outlet.

Failure to follow these instructions

can result in death, re, or electrical

shock.

Wire Size - Use ONLY wiring size recommended for single outlet branch circuit.

Fuse/ Circuit Breaker - Use ONLY the correct HVAC/R 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 eld 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.

Make sure the wiring is adequate for your unit.

If you have fuses, they should be of the time delay type. Before you install or relocate this unit, be sure that the

amperage rating of the circuit breaker or time delay fuse does not exceed the amp rating listed in Table 206.

DO NOT use an extension cord.

The cord provided will carry the proper amount of electrical power to the unit; an extension cord may not.

Make sure that the receptacle is compatible with the air conditioner cord plug provided.

Proper grounding must be maintained at all times. Two prong receptacles must be

replaced with a grounded receptacle by a certied electrician.

The grounded receptacle should meet all national and local codes and ordinances. You must use the three prong plug

furnished with the air conditioner. Under no circumstances should you remove the ground prong from the plug.
