INTRODUCTION
This service manual is designed to be used in conjunction with the installation manuals provided with each unit.
This service manual was written to assist the professional HVAC service technician to quickly and accurately
diagnose and repair any malfunctions of this product.
This manual, therefore, will deal with all subjects in a general nature. (i.e. all text will pertain to all models).
Regarding the Portable Air Conditioner
This Portable Air Conditioner is designed to provide a quick and easy cooling solution for areas that either do not have
air conditioning or areas that the current system cannot maintain at a comfortable level.
This unit is also great as a back-up system in case the primary cooling system should fail.
Other means of conditioning should be employed when the indoor temperature is either below 17°C (63°F) or above
35°C (95°F) .
This unit is designed with human comfort in mind.
IMPORTANT:It will be necessary for you to accurately identify the unit you are
servicing, so you can be certain of a proper diagnosis and repair.
(See Unit Identication.)

Window installation
Maintain a clear distance (from walls, furniture, etc.)
of at least 10 inches around the unit to allow proper
air circulation and prevent damage to the unit.
Important: Do not over-stretch the exhaust tube or
make any unnecessary bends in it.
Installing the window adapter kit
Note: The window adapter kit must be installed and
connected for the air conditioner to work properly in
Cool mode. The window adapter kit is not required
when using the unit in Heat, Dehumidify, or Fan
modes.
Your window adapter kit has been designed to fit
most standard vertical and horizontal window
applications. However, it may be necessary for you to
improvise/modify some aspects of the installation
procedures for certain types of windows.
1. Open window. (fig.A)
2. Place window panel with extensions into window
frame and adjust to width of window. (fig.B)
Window adapter kit may be installed vertically as
well as horizontally. This installaton may also be
used for crank style windows. (fig.E)
3. Tighten the four screws on the window panel to
secure the window panel extensions.
4. Close window. (fig.C)
5. The window adapter kit should now fit securely
within the window frame and you can now attach
the air exchange tubes. If you are having trouble
attaching the air exchange tubes, you may attach
the tubes prior to installing the window adapter kit.
Attaching the air exchange tubes to the air
conditioner
1. Attach the tubes to the window adapter kit.
2. Attach the other end to the air conditioner.
To attach air exchange tubes: push tube onto tube
adapter and twist until the tab is in place in the hole
on the tube.
To remove air exchange tubes: twist the end until the
tab is clear of the hole in the tube and pull off.
Do not attach the tubes if using the unit in
dehumidify or heat mode.

Your ZoneAire® Portable Air Conditioner is designed to
evaporate the condensation removed from the interior space
through the exhaust hose. Under certain conditions it is
possible that the unit will not evaporate 100% of the removed
moisture.
The unit is designed with a built-in reservoir to accumulate
excess condensate and help dispose of it.
Internal Water Level
1. Under any mode if the water level is in the “low” area the
unit will function normally.
2. If the water level is in the “normal” area the unit will
continue to function normally while internally evaporating
the condensate.
3. If the unit cannot evaporate all of the condensate internally,
the tank may become full. If the tank becomes full, the unit
will turn off, and the Water Full light will illuminate.
Draining Water
The water can be drained from the unit by removing the base
stopper and letting the water drain by gravity.
1. When the WATER FULL lamp is on unplug the unit
and move the unit to a suitable location for draining the
condensation.
2. Using the gravity drain method, ensure that the base
stopper is located above a suitable area for draining the
condensate and remove the stopper. Re-install the stopper
once all water has drained.
3. Return the unit to the original location and restore power
and duct connections.
4. The WATER FULL indicator should be off and the unit will
return to normal operating mode.
Permanent Drainage
For permanent and continuous drainage, a 1/2" hose may be
attached to the unit and led down a drain.
8
Maintenance
Draining excess water
Condensed water may accumulate in the unit. If the
internal tank becomes full, the Warning Light will shine
and the unit will not operate until the unit has been
drained.
First, uplug electrical cord from wall outlet. Then, drain
excess water from the tank by placing a pan under the
drain valve, removing the drain plug, and letting the
water drain into the pan.
When the water stops draining out, replace the drain
plug, and remove the pan of water. Operate the air
conditioner in fan mode to dry the interior of the unit.
Always drain the unit before putting it into storage.
Cleaning and Maintenance
• The unit has an air filter that must be cleaned with
water every two weeks and put back in the unit after it
is completely dry.
• The air discharge grille can be cleaned with a rag or
sponge, warm water and mild detergent.
• Never use hot water, bleach, gasoline, acids, cleaning
fluid or a brush to clean the unit. This will damage the
cabinet and the air discharge area.
• Do not wash the unit with a hose.
Cleaning the filter.
1. Turn Power OFF.
2. Remove the air filter by grasping the bottom and
pulling it up and out of the unit.
3. Wash in hot soapy water, rinse and shake dry.
4. Replace the filter with the front of the filter toward you.
5. To dry the filter thoroughly, run your unit in fan mode
for a few minutes. Remember, only a clean filter works
properly and delivers top efficiency at every setting.

Warning: Make sure unit is unplugged before
performing any maintenance procedure.
Proper use and care of
your air conditioner will
help ensure longer life of
the unit. It is
recommended to have a
professional annually
inspect and clean the coils
and condensate water
passages. Expense of
annual inspection is the
consumer’s responsibility.
CAUTION:
• Use only AAA or IEC R03 1.5V batteries.
• Do not attempt to recharge the supplied batteries
• All batteries should be replaced at the same time.
• Do not dispose of the batteries in a fire as they may
explode.
• Do not mix old and new batteries.
• Do not install the batteries with the polarity (+/–)
reversed.
• Do not mix alkaline, standard (carbon - zinc), or
rechargeable (nickel-cadmium) batteries.
• Keep batteries and other things that could be
swallowed away from young children. Contact a
doctor immediately if an object is swallowed.

CAUTION
Failure to keep air filter clean will result
in poor air circulation. DO NOT operate
without filter. This can render the unit
inoperative.

MAINTENANCE / SERVICE
Unplug and/or disconnect all electrical power
to the unit before performing inspections,
maintenances or service.
Failure to do so could result in electric shock,
serious injury or death.
WARNING
RISK OF ELECTRIC SHOCK
Preparation for storage
1. Turn off the air conditioner, disconnect the power.
2. Perform proper maintenance to the air lter and other
parts.
3. Open the base stopper to drain out all of the water from
the base. Operating the unit in fan only mode for 12 hours
will help ensure there is no moisture within the unit.
4. Cover the unit to prevent dust or lth from entering the unit.
Cleaning the air lter
If the air lter is blocked with a lot of dust, the air ow volume
will be reduced. Clean the lter once every two weeks.
Open and clean the air lter:
1. Pull the lter out as shown in the drawing.
2. Take out the air lter from the lter cover.
3. Wash the air lter by immersing it gently into warm (about
40°C or 104°F) water with a neutral detergent or vacuum
the lter clean.
4. Rinse the lter and dry it thoroughly in a shaded place.
5. Install the air lter back to its original place.
Cleaning the air conditioner
Clean the surface of the unit with a damp cloth, then dry us-
ing a duster or similar.
Do not use chemical solvent (like benzene or alcohol) to
clean the surface of the unit. If you do so, the surface may
be scratched, damaged or even cause the case to become
deformed.
Prior to operating seasons
1. Check to ensure that the air inlets and outlets of the unit
are not blocked.
2. Make sure that air lter is properly in place before operat-
ing the machine. If the machine is operated with air lter
removed, dust and foreign objects will result in faulty per-
formance of the air conditioner.
