For best cooling performance and highest energy efficiency
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 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: The 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 manufacturer. We recommend you contact our
Technical Assistance Line at 1-800-541-6645 ext. 662. To
expedite service, please have your model and serial number
available.
Keep the filter clean
Make sure that your air conditioner is always in top
performing condition by cleaning the filter reg u lar ly.
In struc tions for removing and cleaning the fi lter can be
found on page 5.
Provide good airflow
Make sure the airfl ow 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. Airfl ow
is critical to good operation. It is just as important on the
outside of the build ing that the airfl ow around the unit
exterior is not blocked.
Unit placement
If your air conditioner can be placed in a window or wall
that is shaded by a tree or another building, the unit will
operate even more effi ciently. Using drapes or blinds on
the sunny side of the dwelling will also add to your unit’s
effi ciency.
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 effi ciency. If the seal gasket
has not been installed, please refer to your installation
instruction manual.
