Mobile Air Conditioner
This Mobile Air Conditioner is a small size appliance which can control the temperature and
humidity in a room. Its flexible characteristics make it easy to use on different occasions and in
different rooms. It also has multiple functions including cooling, heating, dehumidifying, and fan
ventilation. This unit is designed es pecially for the hom e, office , spot cooling/he ating, e tc. it ha s a
compact design compared to others with the same cooling capacity. Power consumption and
noise are especially low.

ATTENTION
Before you use your Mobile Air Conditioner, please read this manual carefully. This Instruction
Manual is for reference only, and does not constitute a contract. We reserve the right to make
technical changes without prior notice.

Theory of Operation
The gas has a heat exchange with air in a room and changes into liquid, then passes to a capillary
tube to lower temperature and pressure and enters into the evaporator. With heat exchange,
refrigerant absorbs heat to lower the temperature. The evaporator is lower than th e d ew point
temperature of air in the room; water vapor will condense on the outside surface of the
evaporator and drop down into the drain tank. This cycle lowers the relative humidity in the room
and attains the goal of dehumidification.

OPERATION
ATTENTION:
DEHUMIDIFYING AND COOLING OPERATION
The operating ranges for cooling and dehumidifying operation is 62ºF - 95ºF.

LOCATION:
Put the mobile air conditioner at an open place where the air outlets cannot be covered up. Place
the unit no less than 20 inches away from a wall or other obstacle.

POWER SUPPLY:
Before connecting the air conditioner to the power supply, please check:
The power supply is rated voltage 115V +- 6%.
The power supply line is PROPERLY grounded and sized for a pickup current of 20A, so as to
avoid voltage drops when starting the air conditioner.
The unit is connected to a 16Amp socket by a 16Amp plug. The wire size should be 10AWG.

This room air conditioner is equipped with a power supply cord required by UL. This
power supply cord contains state-of-the-art electronics that sense leakage current. If
the cord is crushed, the electronics detect leakage current and power will be
disconnected in a fraction of a second.

please replace it with a special power supply cord by a qualified electrician.

If the power supply cord of the unit is damaged,

NOTE: Your unit’s device may differ from the ones shown.

OPERATION

In order to prevent power fluctuations during the start of the compressor, the following
installation conditions apply:

1. The power source must be capable of handling 16A continuous.

2. Avoid connecting other equipment to this power source.

3. For power details of the air conditioner, refer to the rating plate of the product.

OPERATION
WATER DRAINAGE
When operating the air conditioner in cooling or dehumidifying mode under normal conditions,
the condensation water is automatically evaporated from an internal drip pan out through the
exhaust duct. Under extremely high humidity conditions, the water in the drip pan may reach a
level that triggers a shut-off mechanism. The compressor and fan will turn off and th e water must
be drained via one of the following two methods.

CONTINUOUS DRAINAGE
When the unit is operating on continuous drainage mode, excess condensatio n in the drip pan is
discharged by gravity through the drainage tube to either an external tank (not provided) or to a
condensation water pump device (Optional Item). When the unit is operating on continuous
drainage mode, it can operate continuously regardless of humidity level.

Installation Steps:
Remove the plug from the drainage spout.
Connect the drainage tubing to the drainage spout.
Place the other end of the drainage tube into either an external water
tank or the inlet side of a condensation water pump.

MANUAL DRAINAGE
When the unit is operating in manual drainage mode, excess
condensation in the drip pan will rise until it reaches a predetermined level, at which time the air
conditioner will signal a warning (E4 on LCD) and shut off. To drain the excess condensation, turn
off the conditioner, remove the drain plug and allow water to drip into an external p an or draina ge
tubing.

Warning: Do not operate the air conditioner without the drain plug unless the drainage tube is
directed to an external drain or bucker. Dripping water may damage wood floor and carpet and
may also cause injury if not properly contained.

THE AIR EXHAUST DUCT MOUNTING MENTOD CAUTION

Fix the square end of the exhaust duct to the exhaust terminal of the unit.
Put the other end (discharge) to the nearest window.

ATTENTION:
The length of the air exhaust must be between 19”-78”
When mounting, try to keep the air exhaust duct horizontal.

Correct mounting shown below. (If mounting in the wall, the height of the hole should be 15”-51”
above the floor)

21

WINDOW KIT INSTALL ATION

Open window or sliding door approximately 5 inches (13 cm). Adjust the length of the window kit
to the same length of the window or sliding door. Use
two or three panels if necessary and secure panels
into place by fastening the 3/4” Phillips head screws
into the pre-drilled panel holes.
Alternatively you may need to mark a single panel
and cut it down to properly fit the window opening.
The window kit (three panels) has a maximum length
81 inches.
Place the window kit between the window and the
window frame as shown in the picture to the right.
Close the window onto the window kit to form a tigh t
seal.
Attach the exhaust duct window kit adapter to the
window kit. Tabs located on the adapter will lock into
place securing the adapter to the window kit.

NOTE:
Using the window kit will cause the window not to be properly closed and locked. Consider taking
additional security measurements.

MAINTENANCE

WARNING
We recommend you follow the cleaning and maintenance operations regularly as indicated in the
instructions. Unplug the unit before performing any cleaning operations to prevent accidents
caused by electrical shock.

AIR FILTER
If the air filter is clogged with dust the air flow volume is reduced.
For this reason, clean the filter regularly.

To remove the air filter, lift up the filter cover and pull the air filter out from the
cover.

Once the filter is dry, hook the filter onto its cover using the fastening hooks on
the inside of the cover. Place the hooks on the front into the holes on the
structure itself and push it back into place.

AIR CONDITIONING UNIT SURFACES
Clean the surfaces of the air conditioning unit with a damp cloth and dry it with a dust cloth.

WARNING:
KEEP AWAY FROM FLAMMABLE FLIUIDS OR SUBSTANCES!
