Congratulations

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

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 filter frequently (See Routine Maintenance, Page 27).

4.Do not block the air flow to and from the unit.

5.A dirty filter or improperly set controls can affect the cooling ability of the unit.

6.If cooling is weak and you have verified that the filter is clean

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

Working principle and special functions for cooling

Principle:

Air conditioner absorbs heat in the room and transmit to outdoor and discharged, so that indoor ambient temperature decreased, its cooling capacity will increase or decrease by outdoor ambient temperature.

Anti-freezing function:

If the unit is running in COOL mode and in low temperature, there will be frost formed on the heat exchanger, when indoor heat exchanger temperature decreases below 32ºF, the 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 function will act, the heat running will stop for 8-10mins.

*During the auto defrosting, the fan motors of indoor unit and outdoor unit will stop.

*During the defrosting, the indoor indicator flashes, the outdoor unit may emit vapor. This is due to the defrosting, it isn't malfunction.
