ELECTRICAL SHOCK HAZARD
WARNING
Make sure your electrical receptacle has the same
configuration 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
electrical shock, serious injury or death.
Keep the filter clean
Make sure that your air conditioner is always in top performing condition
.ylralugerretlifehtgninaelcyb
Provide goodair flow
Make sure the airflow to and from the unit is clear. Your air conditioner puts the
conditioned air out at the top of the unit, and takes in unconditioned air at the
bottom. Airflow is critical to good operation. It is just as important on the outside
.dekcolbtonsiroiretxetinuehtdnuorawolfriaehttahtgnidliubehtfo
Unit placement
If your air conditioner can be placed in a window or wall that is shaded by a tree
rosepardgnisU.yltneiciffeeromneveetarepolliwtinueht,gnidliubrehtonaro
blinds on the sunny side of the dwelling will also add to your unit’s efficiency.
Insulation
Good insulation will be a big help in maintaining desirable comfort levels.
Doors should have weather stripping. Be sure to caulk around doors and
windows.
Proper installation of seal gasket
Make sure the seal gasket has been installed properly to minimize noise
and improve efficiency. If the seal gasket has not been installed, please
refer to Step 14 of the installation instructions.
Also, if you switch from Coolmode to Fan Only, and switch back to
COOL mode, there is a three minute delay before the compressor comes
back on.
For the best cooling performance and highest energy efficiency
WARNING: Before operating your unit
Make sure the wiring is adequate for your unit.
If you have fuses, they should be of the time delay type. Before you install
rekaerbtiucricehtfognitaregarepmaehttahteruseb,tinusihtetacolerro
or time delay fuse does not exceed the amp rating listed in Figure 1.
DO NOT use an extension cord.
The cord provided will carry the proper amount of electrical power to the
.tonlliwdrocnoisnetxena;tinu
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 certified
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.
To test your power supply cord:
1. Plug power supply cord into a grounded 3 prong outlet.
2. Press RESET (See Figure 2).
3. Press TEST (listen for click; Reset button trips and pops out).
4. Press and release RESET (listen for click; Reset button latches and
remains in). The power supply cord is ready for operation.
NOTE: LCDI device is not intended to be used as a switch.
Once plugged in the unit will operate normally without the need to reset
the LCDI device.
If the device fails to trip when tested or if the power supply cord is
damaged it must be replaced with a new supply cord from the manufac-
turer. We recommend you contact our Technical Assistance Line at
[phone] ext. 845. To expedite service, please have your model
and serial number available.
