certificate from an industry-accredited assessment
authority, which authorises their competence to handle
refrigerants safely in accordance with industry, recognized
assessment specification.
warning
This unit uses a flammable refrigerant. R290
If refrigerant leaks and comes in contact with fire or heating
part, it will create harmful gas and there is a risk of fire.

THE FOLLOWING SHOULD ALWAYS BE OBSERVED FOR SAFETY
The environmentally friendly R290 is used as the refrigerant. R290 has no
damaging influence on the ozone layer (ODP), a negligible greenhouse effect
(GWP) and is available worldwide. Because of its efficient energy properties,
R290 is highly suitable as a coolant for this application. Special precautions
must be taken into consideration due to the coolant's high flammability.
The unit is designed only for use with R-290(propane) gas as the
designated refrigerant
The refrigerant loop is sealed.
Only a qualified technician should attempt to service!
Do not discharge the refrigerant into the atmosphere.
R-290 (propane) is flammable and heavier than air. It collects first in low
areas but can be circulated by the fans.
If propane gas is present or even suspected, do not allow untrained
personnel to attempt to find the cause.
The propane gas used in the unit has no odour. The lack of smell does
not indicate a lack of escaped gas.
If a leak is detected, immediately evacuate all persons from the store,
ventilate the room and contact the local fire department to advise them
that a propane leak has occurred.
Do not let any persons back into the room until the qualified service
technician has arrived and that technician advises that it is safe to return
to the room.
No open flames, cigarettes or other possible sources of ignition should be
used inside or in the vicinity of the units.
Component parts are designed for propane and non-incentive and non-
sparking. Component parts shall only be replaced with identical repair
parts.
Be aware that refrigerants do not have any odour.
FAILURE TO ABIDE BY THIS WARNING COULD RESULT IN AN EXPLOSION,
DEATH, INJURY AND PROPERTY DAMAGE.
Do not use the appliance in any other orientation other than upright
as shown in this manual.

control sequence is as follows:

AFTER SALES SUPPORT
Email: [e-mail]
Phone: [phone] - Mon-Fri 8:30am –4.30pm Page 15
Remove the
rubber seal.
When the unit operates in the cooling function or drying operation, the ambient
temperature sensor senses the evaporator coil temperature.
If it is below -1°C, the compressor will stop operating for 10 minutes
Once it is up to 7℃, the unit restarts in cool operating mode.
Overflow Protection Function
When the water in the water pan exceeds the warning level, the machine will
automatically sound an alarm, and the "FULL" indicator light will flash. At this point,
you need to empty the water from the unit (refer to Drainage Instructions of this
chapter). After the water is emptied, the machine will automatically return to the
working state.
Drainage Instructions
Self- evaporating system
The self-evaporating system uses the collected water to cool the condenser coils for
better, more efficient performance. There is no need to empty the drainage tank in the
cooling operation, only in dehumidifying operation and high humidity conditions. The
condensed water evaporates at the condenser and is evacuated through the exhaust
hose.
Manual Drainage
This unit will stop if the internal water collection bowl is full. If this happens follow the
below for manual drainage.
1. Turn off the unit and unplug the power cord from the
supply.
2. Move the unit carefully so as not to spill the water in
the water pan. NOTE: this may require two people.
3. Find a place to drain the water or place a bucket
below the water outlet on the back of the unit.
4. Unplug the rubber plug and allow it to drain. During
draining the body can be tilted back slightly.
5. When the water is emptied the rubber plug can be re-
inserted securely.
Allow to sit for at least 5 minutes before turning back on.

Continuous drain hose
(Inner diameter=16mm)
Continuous Drainage
For continuous operation or unattended operating in dehumidifier mode, please
connect a hose to the unit at the bottom drainage plug. NOTE: to operate permanent
drainage you need to allow the water to drain outside via gravity.
When the appliance is in cooling or dehumidifying mode, the continuous drainage
house needs to be inserted into the bottom drain hole.
1. Turn off the unit and unplug the power cord from the supply.
2. Remove the plug of the water outlet opening.
3. Securely connect the drain hose and make sure it is
not kinked and clear of obstruction.
4. Place the outlet of the hose over a drain or bucket
and ensure that water could freely flow out of the unit.
5. Do not submerge the end of the hose into the
water; otherwise, it can cause an "Air Lock" in the
hose.
6. As the condensate drain pan has negative pressure,
tilt the drain hose down toward the floor. It is appropriate that the degree of
inclination should exceed 20 degrees.

CLEANING and MAINTENANCE
This appliance contains no user-serviceable parts. Any servicing requiring disassembly
other than cleaning must be performed by a qualified appliance repair technician.
Before Cleaning
Before unplugging the unit ensure all controls are set off.
When not in use or before cleaning, always disconnect the appliance from the
mains supply.
Care and Cleaning
Accumulated dust may be removed from the appliance surface with a dry soft
cloth.
For more thorough cleaning, use a cloth that is slightly moist with a solution of
mild detergent and water.
Never use rough scouring pads or abrasive cleansers on any plastic or metal parts
as the surface may be damaged.
Dry the appliance casing thoroughly with a soft, dry cloth before operating the
unit again.
Filters
Dust collects on the filters and restricts the airflow. The restricted airflow reduces the
efficiency of the system and if it becomes blocked it can cause damage to the unit.
The air filter requires regular cleaning. The air filter is removable for easy cleaning.
Do not operate the unit without an air filter, or the evaporator may be contaminated.
1. Press the POWER button to switch off the unit and unplug the power cord.
2. Remove the filter mesh from the unit.
3. Use a vacuum cleaner to suck dust from the filter.
4. Turn the filter over and rinse the air filter under running water. Let the water run
through the filter in the opposite direction of airflow. Set aside and allow the filter
to air dry completely before reinstalling.

water.
Warning!!! Do not touch the evaporator surface with bare-hand, or may
cause injury to your fingers.
Storing the Air Conditioner
If the machine will be unused for a long period store your appliance and all its
accessories and instruction manual in a safe and dry place.
1. Unplug the unit and remove the exhaust hose and window kit store with the unit.
2. Drain the remaining water from the unit.
3. Clean the filter and let the filter dry completely in a shaded area.
4. Collect the power cord at the water tank.
5. Re-install the filter at its position.
6. The unit must be kept in an upright position when in storage.
7. Preserving the machine in ventilating, dry, non-corrosive gas and safe place
indoor.
ATTENTION:
The evaporator inside the machine has to be dried out before the unit is packed to
avoid component damage and mould. Unplug the unit and place it in a dry open area
for days to dry it out. Another way to dry the unit is to set the humidity point more
than 5% higher than the ambient humidity to force the fan to dry the evaporator for a
couple of hours.
