WARNING
Electrical Shock Hazard
Make sure your electrical receptacle has the
same conguration 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 death, re, or electrical shock.
Make sure the wiring is adequate for your unit.
If you have fuses, they should be of the time delay 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.
Proper grounding must be maintained at all times. Two prong receptacles
must be replaced with a grounded receptacle by a certied electrician.
The grounded receptacle should meet all national and local codes and
ordinances. You must use the three prong plug furnished with the air
conditioner. Under no circumstances should you remove the ground
prong from the plug.
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 on the end of the cord 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 1).
3. Press TEST, listen for click; the RESET button trips and pops out.

Standard Filter Cleaning / Installation Instructions
Figure 2
FRR071
HOW TO CLEAN YOUR AIR FILTER
Your Friedrich room air conditioner is equipped with a permanent/ washable mesh air lter. The lter serves to remove dust, pollen, and other impurities
from the air.
CHECK FILTER LIGHT
Your Friedrich room air conditioner is equipped with a check lter light that will illuminate after *45 – 60 days of fan operation.
To reset the CHECK FILTER reminder press the CHECK FILTER button. (While the reminder is set for 45 – 60 days of operation, we recommend checking
the lter every 30 days for optimal performance.)
*Actual timer is set for 1000 hours of fan cycle operation.
FILTER ACCESS
Remove the FRONT PANEL. Using the handles, pull panel out until it is released from the two retaining snaps. Place the cover aside carefully. Remove the
lter by pulling it from the handles releasing it from the slots on the frame. Wash the lter with water to remove all dust and then rinse, remove water excess
and let it dry – do not twist – then replace the lter by inserting each tab in their respective slot.
Replace the FRONT PANEL by positioning one of the sides in the snaps of the handle rst and then the other side, make sure that both snaps are correctly
aligned and the logo is in the right position.
