Safety Precautions
NOTICE
CAUTION
WARNING
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:
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 flame or
incinerate.
Only certified refrigeration technicians should
service this equipment.
Only use gauge sets designed for use with
R410A. Do not use standard R22 gauge sets.
R410A systems operate at higher pressures
than R22 equipment. Appropriate safe
service and handling practices must be used.

Make sure the wiring is adequate for your unit.
If you have fuses, they should be of the time delay HACR 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 1.
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.
This insures proper grounding. If you have a two prong receptacle you
will need to have it replaced with a grounded receptacle by a certied
electrician. The grounded receptacle should meet all national and local
codes and ordinances. Under no circumstances should you remove the
ground prong from the plug. You must use the three prong plug furnished
with the air conditioner.
Test the power cord
All Friedrich room air conditioners are shipped from the factory with a
Leakage Current Detection Interrupter (LCDI) equipped power cord. The
LCDI device meets the UL and NEC requirements for cord connected air
conditioners effective August 2004.
To test your power supply cord:
1. Plug power supply cord into a grounded 3 prong outlet.
2. Press RESET (See Figure 1).
3. Press TEST, listen for click; the RESET button trips and pops out.
4. Press and release RESET (Listen for click; RESET button latches
and remains in). The power cord is ready for use.
Once plugged in, the unit will operate normally without the need to reset
the LCDI device.
If the LCDI device fails to trip when tested or if the power supply cord is
damaged, it must be replaced with a new power supply cord from the
manufacturer. Contact our Technical Assistance Line at [phone].
To expedite service, please have your model number available.

TIMER and PRE-PROGRAMMED SCHEDULING
The TIMER SCHEDULE has three options:
24-Hour Timer - System default. (already covered)
Residential Schedule (option 1) – 40 Hr. Work Week:
This option causes your unit to raise temperatures to 85°F during the typical
work day, lower them again to 78°F prior to the time when most people will
return home, and raise slightly to 82°F overnight.
Commercial Schedule (option 2) - 5-Day Business Week
This option causes your unit to raise temperature to 84°F after typical
working hours and on weekends when commercial spaces are typically
unoccupied.
(Refer to Addendum 1 in the back of this manual for both Residential and
Commercial Schedule Tables.)
To select between these 3 options, press and hold the button
for 3 seconds. You will then be able to toggle between Timer (default),
