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 7.
Provide good airflow
Make sure that the airflow to and from the unit is unobstructed. Your air conditioner puts the air out on the
right side of the unit, and takes in air on the left side. Airflow is critical for 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.

How to Operate Your ZStar®Room Air Conditioner
The controls will look like the following.
Controls
•FOR NORMAL COOLING
1. Turn the Mode switch to the High, Med, or Low 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 High 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 Low Cool setting.
2. Set the Temperature control as needed.
•EnergySaver Switch
This rocker switch can be depressed to either YES or NO. In the yes position, you will
get the most economical operation. Both the fan and the compressor will cycle on and
off together, maintaining the selected temperature at a more constant level and
reducing the humidity more efficiently. This control will only operate when the unit is in
a cooling mode. In the NO position, the fan will run constantly as long as the unit is in
the cooling mode.
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.

Care and Maintenance
The air filter behind the front grille should be checked and
cleaned at least once every 2 weeks or more often if
necessary.
•To Remove the Filter
1. Remove the front cover by gripping the top outside edges
and pulling toward you.
You will notice that the grille will only open to about a 56°
angle. Do not force the grille open too far.
2. Find the two clips that hold the filter in place.
Gently lift the filter out.
•To Clean the Filter
1. Clean with warm water. Be sure to shake all water off
before replacing the filter.
2. Carefully position the filter, bottom first, and snap the
grille back into place.
CAUTION: DO NOT operate the air conditioner without a filter
because dirt and lint will clog it and reduce
performance.
The coils on the outdoor side of the air conditioner should be
checked regularly. If they are clogged with dirt or soot they may be
professionally steam cleaned, a service available through a dealer.
Turn the air conditioner off and remove the plug
from the wall outlet before cleaning. To clean, use water and a mild detergent. Do not use bleach or abrasives.
In humid weather, excess water may cause the
BASE PAN to overflow. To drain the water,
remove the DRAIN CAP and secure the DRAIN
PIPE to the rear hole of the BASE PAN.
