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,
efcient 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.
Clean the filter frequently (See Routine Maintenance, Page 23).
3.
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 veried 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:
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.

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 decreased below 0 , 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.
After defrosting finished,the heating will recover automatically.
*
℃
Anti-cool wind function:
In "Heat" mode, under the following three kinds of state, if indoor heat exchanger doesn't
arrive at certain temp., indoor fan will not act, in order to prevent cool wind blowing(within
2 mins):
1. Heating starts. 2.After Auto Defrost finished. 3.Heating under the low temperature.
Gentle Breeze
In the following situation, the indoor unit may blow gentle breeze, and
the guide louver rotate to a certain position:
1. In “Heat” mode, the unit turned on, the compressor doesn’t arrive the starting condition
2. In “Heat” mode, the temperature arrive at the setting value and the compressor stop
running about 1min.

Install outdoor unit
Electrical wiring
Remove the cover on right side of outdoor unit.
1.
Take off wire clamp. Connect and fix the power connection
2.
cord to the terminal board. Wiring should be sized for
indoor unit too.
3.
Fix the power connection cord with wire clamp.
4.
Confirm if the wire has been tighend properly.
5.
Reinstall terminal cover.
NOTE:
●
Incorrect wiring may cause malfunction of parts.
●
After the wire has been fixed, ensure that no wires
will contact others.
Air purging and leakage test
1. Connect charging hose of manifold valve to charge end of low pressure
valve (both high/low pressure valves must be tightly shut).
2. Connect joint of charging hose to vacuum pump.
3. Fully open handle handle of Lo manifold valve.
4. Open the vacuum pump to evacuate. At the beginning, slightly
loosen joint nut of low pressure valve to check if there
is air coming inside. (If noise of vacuum pump has
been changed, the reading of multimeter is 0) Then
tighten the nut.
5.
Keep evacuating for more than 15 mins and
make sure the reading of multi-meter 500 Microns
and holding.
6. Fully open high/low pressure valves.
7. Remove charging hose from charging end of low pressure valve.
8. Tighten bonnet of low-pressure valve. (As shown in Fig.9)
Condensate drainage of outdoor unit (no for cooling only)

in the outdoor unit can be properly discharged by drainage
pipe .
Installation method:set the drain connection in 25 hole of the
chassis has been installed and then connect drainage pipe
