BEFORE FIRST USE
POSITIONING THE DEHUMIDIFIER
• Remove all packaging and ensure that all parts are included and
undamaged prior to use.
• Ensure that the dehumidier is assembled correctly.
A badly positioned dehumidier will have little eect. Ensure circulation
of air is not restricted around the appliance.
• Place the dehumidier on a flat, rm, level surface.
• Allow at least 20cm clearance from walls/obstructions all around
the appliance.
• This dehumidier is designed for indoor residential use only.
Commercial or industrial use will invalidate the warranty.
• Use in an enclosed area for maximum eciency. Close all external
doors and windows to create an eective operating environment.
• Do not use outdoors.
• Excess moisture is dispersed throughout your home, therefore the
dehumidier should be positioned in a central and unobstructed
location so that it can draw the moist air towards it. A warm hallway
or landing is an excellent position for your dehumidier. If possible,
leave interior doors ajar to allow air circulation.
• Alternatively, if you have a serious problem in one area you can
begin by positioning the dehumidier there and move it to a more
central location at a later date.
Note: The dehumidier should not be placed directly against a radiator
or other heat source.
Note: When positioning your dehumidier, ensure that it is placed clear
of any obstacles that may limit the air circulation.
Note: Do not force the castors to move over carpet or uneven surfaces
or move the appliance with water in the tank as it may tip over and spill water.

QUICK REFERENCE GUIDE
SMART Mode:
• This is designed for maximum convenience and maintains the ideal
domestic environment humidity level of 55% while saving electricity.
It is recommended for most users.
• When the humidity setting is nished, the appliance will operate
according to the target setting humidity. When it reaches the target
humidity (the selected humidity is 2% lower than the user selected
humidistat setting), the compressor stops running, the fan continues
running for ve minutes and then stops, and the louvre will close,
but the display remains.
• The appliance keeps this status for 30 minutes, the louvre
re-opens, and the fan starts running to test the current humidity.
If it has reached the setting value, the compressor starts running. If
the current humidity has not reached the setting value, the fan will
stop after 5 minutes, the louvre closes shuts and keeps this status
again for 30 minutes, before following the same cycle as above.
Note: If the DEH. mode is set at 35% humidity, and the appliance is
running in Laundry drying mode it will continue dehumidifying, even
if the ambient humidity is less than 35%, the compressor will not shut
down. This mode applies to drying clothes and other occasions if the
permanent drainage pipe is tted the unit will not stop running. Humidity
set to achieve room humidity of around 35% is good for a quick drying
boost on an initial run or for emergencies. It is not recommended for
normal operation in a domestic/ home oce environment.
• To allow more moisture in the air, press the humidity control key and
set to a higher percent value (e.g. 60-70%).
• Humidity set to 50-55% RH, recommended setting, great for
domestic operation and dry storage.
• Humidity set to 60% RH; great for personal comfort and applications
where 50% RH is considered too dry.

Why doesn't the dehumidier seem to extract much water if the
temperature is low?
This is a compressor dehumidier which works best in temperatures
above 15°C. If the temperature is low and the air is dryer than the setting
on the humidistat the unit will not extract water. If you want to use a
dehumidier for outside buildings, unheated properties, boats or garages
please check our desiccant range.
Why doesn't the unit work/or stops suddenly?
The water tank may be full or displaced. To rectify: empty the tank and
carefully place the tank back in the unit. Also the unit maybe running in
dehumidifying mode with a low room temperature. Please check if the
room temperature is lower than 5°C. If so, the unit will stop working while in
dehumidifying mode (it may be defrosting).
The ambient operating range is between 5°C and 35°C with a relative
humidity ranging from 35% to 80%. For maximum eciency use the unit
between 15°C and 32°C.

WARNING: The appliance should be stored in a well-ventilated room.
The area of the room should be equal to the room area required for
maintenance.
Warning: Appliances should be stored in rooms where there is no
continuous burning re (such as ignited gas appliances) and ignition
sources (such as electric heaters at work).
• All operators or refrigeration circuit maintenance personnel
should obtain a valid certicate issued by an industry-approved
assessment agency to determine their qualication for safe
disposal of refrigerants as required by the industry-approved
assessment specication.
• The maintenance and repair of the equipment can only be carried
out according to the method recommended by the equipment
manufacturer. If other professionals are required to assist in
the maintenance and repair of the equipment they should be
supervised by personnel qualied to use flammable refrigerants.
Inspection of the Site:
• Prior to servicing with flammable refrigerants, a safety inspection
must be performed to ensure that the risk of re is minimized. When
servicing the refrigeration system, the following precautions should
be observed before handling the system.

General Working Area:
• All maintenance personnel and other personnel in the work area
should be aware of the nature of the work being performed and
should work within a conned space that should be avoided. The
work area should be properly segregated to ensure the safety
of working conditions in the work area by controlling combustible
materials.
• Check if the Refrigerant is Present:
• Pre-operation and during operation should be monitored in
the area using an appropriate refrigerant monitor to ensure
that the technicians are aware of the presence of potentially
flammable gases and that all leak detection equipment is suitable
for flammable refrigerants, such as: no spark, fully enclosed or
intrinsically safe.
Fire Extinguisher Placement:
• When performing heat-processing operations on the refrigeration
system or related components, the appropriate re extinguisher
should be located nearby and the refrigerant injection area should
be equipped with a dry powder or carbon dioxide re extinguisher.
Prohibition of Fire:
• When working in connection with exposed pipelines that contain
or have contained flammable refrigerants, all forms of ignition
sources that may cause re or danger to the station should not be
used. All sources of ignition, including smoking, are combustible. The
agent may be released into the surrounding environment. It must
be far away from the area where it is installed, repaired, relocated
or disposed. Before starting work, the surrounding environment of
the equipment must be inspected strictly to ensure that there is no
danger of flammability or re, should set up the mark of
"No Smoking".

Ventilated Area:
• Ensure that the work area is open or fully ventilated before opening
the system or performing hot work operations. Ventilation should be
maintained during operation. Ventilation will safely dilute the leaked
refrigerant and quickly release it into the atmosphere.
Inspection of Refrigeration Equipment:
If you replace electrical components, these electrical components
should be installed in accordance with the day-to-day and night-time
operating regulations. At all times, the manufacturer's maintenance and
repair guides should be followed. If in doubt consult the manufacturer's
technical department. The following inspection items apply to the
installation of flammable refrigerant appliances:
• The charge should be determined according to the size of the room
containing the refrigerant containing components.
• Ventilation equipment should operate normally and vents should be
free from obstructions.
• If an inter-refrigeration, refrigeration cycle is used, check the
presence of refrigerant in the secondary circuit.
• The logo on the appliance should be clearly visible. Marks and
symbols that are indelible.
• Refrigerating lines or electrical components should not be installed
in environments that contain possible housing contact elements,
unless the electrical components are made of corrosion-resistant
materials or suitable corrosion protection measures are taken.

28
Inspection of Electrical Installations:
• The repair and maintenance of electrical components should
include initial safety inspections and component inspection
procedures. If there is a defect that compromises safety, the
appliance power supply must be de-energised until the defect is
properly disposed of. If the defect cannot be completely eliminated
in the end, and must continue to operate, then appropriate
temporary solutions should be taken, report the situation to the
owner of the appliance, and warn all relevant personnel.
• The initial security check should include:
Capacitor discharge should be performed in a safe manner to
avoid sparks.
No exposed electrical components and wiring during lling,
recycling and cleaning of the system.
Continuity of grounding.
Maintenance of Sealing Elements:
When repairing close components, disconnect the power supply of the
device before opening the sealed cover. If there is power supply during
the maintenance process, uninterrupted leak detection should be
performed on the most dangerous parts to prevent potential dangerous
situations from occurring.
• In the following maintenance of electrical components, special care
shall be taken not to cause maintenance methods aecting the
degree of protection of the enclosure. Improper maintenance may
result in damage to the cables, excessive connection, improper
installation of the terminals, damage to the seals and sealing. Cover
installation errors and other hazards. Ensure the installation of the
equipment is safe and reliable.
• Ensure that the sealing or sealing material does not lose its eect
of preventing the entry of flammable gases due to aging, and
the replacement parts should comply with the manufacturer's
specications.

• Note: The use of silicon-containing sealants may reduce the
detection capabilities of leak detection equipment, intrinsically safe
components do not have to be isolated before operation.
Intrinsically Safe Component Maintenance:
• If it cannot be ensured that the appliance does not exceed the
limits of the allowable voltage and current during use, no permanent
inductance or capacitive load must be used in the circuit. The
essential Ankh-type element is the only element that can continue
to operate within the flammable gas. The test instrument should be
set in the correct gear.
• If the replacement component can only use components specied
by the manufacturer, other components may cause the refrigerant
that is leaking in the air to catch re.
Cable:
• Check the cable for wear, corrosion, overpressure, vibration, sharp
edges or other adverse environmental eects. This inspection
should also consider the impact of aging or the continuous vibration
of the compressor and fan on the cable manufacturing.
Inspection of Flammable Refrigerants:
• Inspection of refrigerant leakage should be done in an environment
where there is no potential source of ignition and should not be
detected using a halogen probe (or any other detector using an
open flame).

Leak Detection Method:
For systems containing flammable refrigerants, the following methods
for detecting leaks are acceptable:
• Electronic leak detectors can be used for the detection of
flammable refrigerants, but the sensitivity may not be sucient
or may require recalibration (the instrument calibration should be
performed in a refrigerant-free environment) to ensure that the
leak detector does not become a potential ignition source, and
applies to the measured refrigerant the leak detector should be
set to the lowest flammable concentration of the refrigerant (in
percent), calibrated with the used refrigerant and adjusted to the
appropriate gas concentration test range (max.25%).
• The leak detection fluid is suitable for most refrigerants, but do not
use oxygenated solvents to prevent oxygen and refrigerant from
reacting and corroding the copper pipeline.
• If leakage is suspected, all open flames should be removed from the
site or extinguished.
• If a leak occurs where welding is required, all the refrigerant should
be recovered, or the refrigerant should be completely isolated away
from the leak (using shut-o valves). Before welding and during
welding, use oxygen-free. Nitrogen (OFN) puries the entire system.

Remove and Vacuum:
• When performing maintenance or other operations on the
refrigeration circuit routine procedures should be followed, but the
flammability of the refrigerant should also be considered. Follow
these procedures:
- Clear refrigerant.
- Purge the line with inert gas.
- Vacuum.
- Purge the pipe again with inert gas.
- Cutting pipelines or welding.
• Refrigerant should be recycled to a suitable storage tank. The
system should be purged with oxygen-free nitrogen to ensure
safety. This process may need to be repeated several times. This
operation must not be performed with compressed air or oxygen.
• In the purging process, the system is lled with oxygen-free nitrogen
to reach the working pressure under the vacuum state, and then
the oxygen-free nitrogen is discharged to the atmosphere. Finally,
the system is evacuated to a vacuum, and the process is repeated
until the refrigerant in the system is completely removed. After
the last charge of anaerobic nitrogen, the gas is released to
atmospheric pressure and the system can then be welded. Such as
pipe welding operations, the above operation is very necessary.
• Make sure there are no ignition sources near the outlet of the
vacuum pump and that it is well ventilated.

Charge the Refrigerant Program:
As a supplement to regular procedures, add the following requirements:
• Ensure that when using the refrigerant charging equipment, no
inter-contamination between dierent refrigerants will occur,
and the piping for charging the refrigerant should be as short as
possible to reduce the residual amount of refrigerant therein.
• Tanks should be kept vertically upward.
• Ensure that the cooling system has been grounded before lling the
refrigerant.
• Label the system after lling (or when it has not been completed).
• Must pay attention not to overcharge.
The pressure test was performed with oxygen-free nitrogen before
recharging the system. After the ling was completed, a leak test was
performed before the test operation. A leak test should be conducted
when leaving the area.

Recycling:
The refrigerant in the system needs to be removed during maintenance
or scrap. It is recommended that the refrigerant be completely removed.
When loading the refrigerant into the tank, use only a dedicated
refrigerant tank. It is necessary to ensure that the capacity of the tank
is compatible with the amount of refrigeration injection in the entire
system. All are tanks intended to be used for refrigerant recovery and
are identied with this refrigerant (i.e. refrigerant recovery dedicated
tanks). Tanks should be tted with pressure relief and shut-o valves
and in good condition. If possible, empty storage tanks should be
evacuated and kept at room temperature before use.
The recovery equipment should maintain a good working condition,
and the equipment operation instructions should be provided for
easy reference. The equipment should be suitable for the recovery of
flammable refrigerants. In addition, there must be qualied weighing
instruments that can be used normally. The hose should be connected
using a leak free, releasable joint and keep it in good condition. Before
using the recycling equipment, check whether it is in good condition,
whether it is well maintained, and all the electrical components are
sealed to prevent the re from leaking once the refrigerant leaks. If
in doubt, consult the manufacturer. Recovered refrigerant should be
contained in the used storage tank, attached with shipping instructions
and returned to the chiller manufacturer. Do not mix the refrigerant in
the recovery equipment, especially the storage tank.
If you remove the compressor or remove the compressor oil make sure
that the compressor is evacuated to a suitable level to ensure that
there is no residual flammable refrigerant in the lubricant. Evacuation
is performed before the compressor returns to the supplier. Only use
electric heating to heat the compressor housing to speed up this
process. When the oil is discharged from the system, safety should be
ensured.
