Electrical Shock Hazard
Plug into a grounded 3 prong outlet. Do not remove ground prong.
Do not use an adapter.
Do not use an extension cord.
Failure to follow these instructions can result in death, fire, or electrical shock.
All wiring should be done in accordance with local electrical codes and regulations.
NOTE : Aluminum house wiring may pose special problems. Consult a qualified electrician.
■ ELECTRICAL SAFETY
IMPORTANT GROUNDING INSTRUCTIONS
The air conditioner has a three-prong grounding plug on its power supply cord, which must be plugged into properly grounded three-prong wall receptacle for your protection against possible shock.
FUSE – Use a time-delay fuse or circuit breaker. Refer to the nameplate for proper power supply requirements.
208/230 VOLT UNITS
These units are equipped with a three-prong grounding plug on the power supply cord, which must be plugged in to a matching, properly grounded three-prong wall receptacle for your protection against possible shock hazard. If such an outlet is not present, one must be installed by a qualified electrician in accordance with the National Electrical Code and local codes and ordinances.

Turn the knob clockwise for greater cooling.
Turn the knob counter-clockwise for more moderate cooling.
• FOR NORMAL COOLING
1. Turn the MODE Knob to the Med Cool setting.
2. Set the Temperature Knob to the desired temperature (the mid-point is a good starting position).
If the room temperature is not satisfactory after a reasonable time, adjust the control to a cooler or warmer setting, as appropriate.
• FOR MAXIMUM COOLING
1.Turn the MODE Knob to the High Cool setting.
2.Set the Temperature Knob to the coolest temperature setting all the way to the right.
• FOR QUIETER OPERATION
1.Turn the Operation Knob to the Low Cool setting.
2.Set the Temperature Knob as needed.

The controls will look like one of the following:
Controls – Cooling & Heating
Off |
- Turns the air conditioner off. |
Fan Only |
- The low fan speed operation without cooling/heating. |
Low Cool |
- Cooling with the low speed fan operation. |
High Cool |
- Cooling with the high speed fan operation. |
Low Heat |
- Heating with the low speed fan operation. |
High Heat |
- Heating with the high speed fan operation. |
Turn the Temperature Knob to the desired setting. The central position is a normal setting for average conditions. You can change this setting, if necessary, in accordance with your temperature preference.
The thermostat automatically controls cooling or heating, but the fan runs continuously whenever the air conditioner is in operation. If the room is too warm, turn the thermostat control clockwise. If the room is too cool, turn the thermostat control counterclockwise.
The compressor will turn on and off to keep the room at the set temperature.
In the heating operation, the electric heater will turn on and off to keep the room at the set temperature.
CAUTION
When the air conditioner has been operated in the cooling or heating mode and is turned off or set to the fan position, wait at least 3 minutes before resetting to the cooling operation again.
A slight burning odor may come from the unit when first switching to HEAT after the cooling season is over. This odor, caused by fine dust particles on the heater, will disappear quickly. This is normal operation.

PULL OPEN / PUSH CLOSE
Air Direction
The direction of air can be controlled by adjusting the horizontal and vertical louvers.
• HORIZONTAL AIR-DIRECTION CONTROL
The horizontal air direction is adjusted by moving the vertical louver. The lever for the vertical louver is located in the right and left side of the air discharge.
• VERTICAL AIR-DIRECTION CONTROL
The vertical air direction is adjusted by moving the horizontal louver.

Care and Maintenance
TURN THE AIR CONDITIONER OFF AND REMOVE THE PLUG FROM THE POWER OUTLET.
Air Filter Cleaning
The air filter should be checked at least twice a month to see if cleaning is necessary. Trapped particles in the filter will build up and block the airflow. This reduces the cooling capacity and can also cause an accumulation of frost on the cooling coils.
If the filter becomes torn or damaged you should replace it immediately. Replacement filters are available from your salesperson, dealer, and authorized customer service centers.
1. Open the inlet grille downward by grasping the top outside edges of the inlet grille and pulling it towards you.
2. Remove the air filter from the front grille assembly by pulling the air filter up slightly.
3. Wash the filter using lukewarm water and a mild detergent.
4. Gently shake all excess water from the filter.
Make sure the filter is completely dry and replace the filter back into the unit.
How to Attach Front Grille to Cabinet
The front grille can be removed for cleaning or to check the model and serial numbers. For your safety, you should attach the front grille using the following procedures.

CAUTION
Installing the FRIEDRICH USC sleeve ensures optional performances of the unit.
If you decide to keep the existing wall sleeve, you have to redirect the louvers at the back of the wall sleeve. Refer to FIG. 8 on p14. The use of pliers is recommended. If you DO NOT redirect, you run the risk of poor performance or premature product failure. This is not covered under the terms of the FRIEDRICH warranty.
•Pick a location which will allow the conditioned air to blow into the area you want. Good installation with special attention to the proper position of the unit will lessen the chance that service will be needed.
