WARNING

Read Installation Operation
Manual

Please read this manual thoroughly prior to
equipment installation or operation.

It is the installer’s 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.

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

Thank you for your decision to purchase Friedrich. Your new Friedrich has been carefully engineered and manufactured to give you many years of dependable,

efcient operation, maintaining a comfortable temperature and humidity level. Many extra features have been built into your unit to assure quiet operation,

the greatest circulation of cool, dry air, and the most economic operation.

General Instructions

This Installation and Operation Manual has been designed to insure maximum satisfaction in the performance of your unit. For years of trouble-free service,

please follow the installation instructions closely. We cannot overemphasize the importance of proper installation.

and the controls are properly set, the unit may need service and

WARNING

Refrigeration system

under high pressure

Do not puncture, heat, expose to flame or
incinerate.

Only certified 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.

Here are some suggestions to help you use your

new Friedrich most efficiently:

1. Carefully read and follow the installation instructions.

2. Make sure the unit is the right capacity for the area being cooled.

An undersized unit makes the unit work too hard, using more
electricity than needed and increases wear. An oversized unit
will cycle on and off too rapidly, and therefore cannot control
humidity as well.

3. Clean the lter frequently (See Routine Maintenance, Page 27).

4. Do not block the air ow to and from the unit.

5. A dirty lter or improperly set controls can affect the cooling

ability of the unit.

6. If cooling is weak and you have veried that the lter is clean

you should call your Friedrich service provider to check the unit.

7. Keep blinds, shades and drapes closed on the sunny side of the
room being cooled to reduce radiant heat.

8. Proper insulation helps your unit maintain the desired inside
temperature.

9. Whenever possible, shade south and west facing windows.

10. Keep window coverings away from the unit to provide free air ow.

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:

indoor unit microcomputer will stop compressor running and protect the unit.

Working principle and special functions for heating

Principle:

Air conditioner absorbs heat from outdoor and transmits to indoor, in this way to increase

*

room temperature. This is the heat pump heating principle, its heating capacity will be
reduced due to outdoor temperature decrease.
If outdoor temperature becomes very low, please operate with other heating equipments.

*

Defrosting:

When outdoor temperature is low but high humidity, after a long while running, frost will

*

form on outdoor unit, that will effect the heating effect, at this time, the auto defrosting
