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.
