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 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 figure 1.

DO NOT use an extension cord.

The cord provided will carry the proper amount of electrical power to the unit; an extension cord will not.

Make sure that the receptacle is compatible with the wall plug provided.

This insures proper grounding. If you have a two-prong receptacle you will need to have the circuit replaced by a certified electrician with a grounded circuit that meets all national and local codes and ordinances. You must use the three-prong plug furnished with the air conditioner.

Figure 1

For the Best Cooling Performance and Energy Efficiency

Keep the filter clean

Make sure that your air conditioner is always in top performing condition by cleaning the filter regularly. Instructions for removing and cleaning the filter can be found on page 6.

Provide good airflow

Make sure that the airflow to and from the unit is clear. Your air conditioner puts the air out at the top of the unit, and takes in air at the bottom. Airflow is critical to good operation. It is just as important on the outside of the building that the airflow around the unit exterior is not blocked.

Unit Placement

If your air conditioner can be placed in a window or a wall that is shaded by a tree or another building, the unit will operate even more efficiently. Using drapes or 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.

Function Controls

When the air conditioner has finished cooling the room and is turned off or set to the fan position, wait at least 3 minutes before resetting to the cooling operation again.

FUNCTION CONTROL

This dial allows you to select 2 cooling and 2 fan speeds. Turn to Off to turn everything off. Turn to Hi Cool for quick cooling. Turn to Lo Cool to maintain a desired temperature. The Hi Fan setting provides maximum circulation of filtered room air without cooling. The Lo Fan setting is a slow fan speed without cooling.

TEMPERATURE CONTROL

This dial is the thermostat. Turn it clockwise for cooler and counterclockwise for a warmer temperature.

• FOR NORMAL COOLING

1. Turn the Mode switch to the Hi Cool or the Lo Cool setting.

2. Set the Temperature control to the desired temperature point (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 switch to the Hi Cool setting.

2. Set the temperature control to the coolest temperature point (all the way to the right).

• FOR QUIETER OPERATION

1. Turn the Mode switch to the Lo Cool setting.

2. Set the Temperature control as needed.

NOTE: All supporting parts should be secured to firm wood, masonry, or metal.

1. This unit is designed for installation in standard double hung windows with actual opening widths of 22" to 36". The upper and lower sash must open sufficiently to allow a clear vertical opening of 13" from the bottom of the sash to the window stool.

2.If storm window presents interference, fasten a 2" wide wood strip to the inner window sill across

the full width of the sill. The wood strip should be thick enough to raise the height of the window sill so that the unit can be installed without interference by the storm window frame. See Fig. 5-2. The top of the wood strip should be approximately

/4" higher than the storm window frame (STORM WINDOW FRAME) or wood strip (OUTDOORS) to help condensation to drain properly to the outside.

3. Install a second wood strip (approximately 6" long by 11/2" wide and same thickness as first strip) in the center of the outer sill flush against the back off the inner sill. This will raise the L bracket as shown Fig. 5-2.

4. If the distance between STORM WINDOW FRAME and WOOD STRIP MOUNTED ON TOP OF INNER SILL is more than 1", two of wood strips are not necessary.

Troubleshooting Tips

Troubleshooting Tips save time and money! Review the chart below first and you may not need to call for service.

Problem Possible Causes What To Do

■ The air conditioner is unplugged.

■ Thefuseisblown/circuit breaker is tripped.

■ Power failure.

■ Airflow is restricted.

■ The THERMOSTAT may

not be set high enough.

■ The air filter is dirty.

■ The room may have been

hot.

■ Cold air is escaping.

■ Cooling coils have iced up.

■ Ice blocks the air flow and

stops the air conditioner from cooling the room.

• Make sure the air conditioner plug is pushed completely into the outlet.

• Check the house fuse/circuit breaker box and replace the fuse or reset the breaker.

• If power failure occurs, turn the mode control to Off. When power is restored, wait 3 minutes to restart the air conditioner to prevent tripping of the compressor overload.

• Make sure there are no curtains, blinds, or furniture blocking the front of the air conditioner.

• Turn the knob to a higher setting. The highest setting provides maximum cooling.

• Clean the filter at least every 2 weeks. See the operating instructions section.

• When the air conditioner is first turned on you need to allow time for the room to cool down.

• Check for open furnace floor registers and cold air returns.

• Set the air conditioner's vent to the closed position.

• See Air Conditioner Freezing Up below.

• Set the mode control on high fan until the ice thaws

out.

Normal Operation

• You may hear a pinging noise caused by water being picked up and thrown against the condenser on rainy days or when the humidity is high. This design feature helps remove moisture and improve efficiency.

• You may hear the thermostat click when the compressor cycles on and off.

• Water will collect in the base pan during high humidity or on rainy days. The water may overflow

and drip from the outdoor side of the unit.

• The fan may run even when the compressor does not.

• Your air conditioner is designed to cool in warm weather when the outside temperature is above 60°F(16°C) and below 115°F(46°C).
