Safeguard and Protect
Effectively Removes Moisture

1. BEFORE YOU BEGIN
1.1 PRODUCT DESCRIPTION
The dehumidifier is used to remove excessive moisture from the air. The resulting reduction
in relative humidity protects buildings and their contents from the adverse effects of excess
humidity.
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
availableworldwide. Because of its efficient energy properties, R290 is highly suitable as a
coolant forthis application. Special precautions must be taken into consideration due to the
coolant's highflammability.
WARNING
Any person who is involved with working on or breaking into a refrigerant circuit
should hold a current valid certificate from an industry-accredited assessment
authority, which authorizes their competence to handle refrigerants safely in
accordance with an industry, recognized assessment specification.
WARNING
Servicing shall only be performed as recommended by the equipment
manufacturer. Maintenance and repair requiring the assistance of other skilled
personnel shall be carried out under the supervision of the person competent in
the use of flammable refrigerants.
1.2 SYMBOLS FROM THE UNIT AND USER MANUAL
If the user ignores this warning and mishandles the product, it may result in serious
and fatal injury or death to the user.
If the user ignores this note and mishandles the product, it may result in injury to the
user, or material damages.
This unit uses a flammable refrigerant.
If refrigerant leaks and comes in contact with fire or heating part, it will create
harmful gas and there is risk of fire.
Read the USER MANUAL carefully before operation.
Further information is available in the USER MANUAL, SERVICE MANUAL, and the like.
Service personnel are required to carefully read the USER MANUAL and SERVICE
MANUAL before operation.

2.3 SAFETY PRECAUTIONS ON SERVICING
Please follow these warnings when to undertake the following when servicing a dehumidifier with
R290.
2.3.1 Checks to the area
Prior to beginning work on systems containing flammable refrigerants, safety checks arenecessary to
ensure that the risk of ignition is minimized. For repair to the refrigeratingsystem, the following
precautions shall be complied with prior to conducting work on thesystem.
2.3.2 Work procedure
Work shall be undertaken under a controlled procedure so as tominimize the risk of aflammable gas or
vapor being present while the work is being performed.
2.3.3 General work area
All maintenance staff and others working in the local area shall be instructed on the nature ofwork
being carried out. Work in confined spaces shall be avoided. The area around theworkspace shall be
sectioned off. Ensure that the conditions within the area have been madesafe by control of flammable
material.
2.3.4 Checking for presence of refrigerant
The area shall be checked with an appropriate refrigerant detector prior to and during work, toensure
the technician is aware of potentially flammable atmospheres. Ensure that the leakdetection
equipment being used is suitable for use with flammable refrigerants, i.e. no sparking,adequately
sealed or intrinsically safe.
2.3.5 Presence of fire extinguisher
If any hot work is to be conducted on the refrigeration equipment or any associated parts,appropriate
fire extinguishing equipment shall be available to hand. Have a dry powder orCO2 fire extinguisher
adjacent to the charging area.
2.3.6 No ignition sources
No person carrying out work in relation to a refrigeration system which involves exposing anypipe
work that contains or has contained flammable refrigerant shall use any sources of ignition in such a
manner that it may lead to the risk of fire or explosion. All possible ignition sources, including cigarette
smoking, should be kept sufficiently far away from the site of installation, repairing, removing and
disposal, during which flammable refrigerant can possibly be released to the surrounding space. Prior
to work taking place, the area around the equipment is to be surveyed to make sure that there are no
flammable hazards or ignition risks. “No Smoking” signs shall be displayed.

8
2.3.7 Ventilated area
Ensure that the area is in the open or that it is adequately ventilated before breaking into the system
or conducting any hot work. A degree of ventilation shall continue during the period that the work is
carried out. The ventilation should safely disperse any released refrigerant and preferably expel it
externally into the atmosphere.
2.3.8 Checks to the refrigeration equipment
Where electrical components are being changed, they shall be fit for the purpose and to the correct
specification. At all times the manufacturer’s maintenance and service guidelines shall be followed. If
in doubt consult the manufacturer’s technical department for assistance.
The following checks shall be applied to installations using flammable refrigerants:
–The charge size is in accordance with the room size within which the refrigerant containing parts are
installed;
–The ventilation machinery and outlets are operating adequately and are not obstructed;
–If an indirect refrigerating circuit is being used, the secondary circuit shall be checked for the
presence of refrigerant;
–Marking to the equipment continues to be visible and legible. Markings and signs that are illegible
shall be corrected;
–refrigeration pipe or components are installed in a position where they are unlikely to be exposed to
any substance which may corrode refrigerant containing components, unless the components are
constructed of materials which are inherently resistant to being corroded or are suitably protected
against being so corroded.
2.3.9 Checks to electrical devices
Repair and maintenance to electrical components shall include initial safety checks and component
inspection procedures. If a fault exists that could compromise safety, then no electrical supply shall be
connected to the circuit until it is satisfactorily dealt with. If the fault cannot be corrected immediately
but it is necessary to continue operation, an adequate temporary solution shall be used. This shall be
reported to the owner of the equipment so all parties are advised.
Initial safety checks shall include:
-those capacitors are discharged: this shall be done in a safe manner to avoid possibility of sparking;
-that there no live electrical components and wiring are exposed while charging, recovering or
purging the system;
-that there is continuity of earth bonding.

6.4 DRAINAGE
There are two ways of removal collected water produced by the unit.
A. Manual draining: Empty water tank by manual.
B. Continuous draining: Use gravity to drain condensate water by attaching a drain hose.
6.4.1 Emptying the water tank
⚫Unplug the dehumidifier from its power
source.
⚫Pull on the water tank and simply slide out
of the body of the dehumidifier.
⚫Do not remove the float out of the tank.
Make sure that the float can move freely
and that it will actuate the level switch
when the tank is full.
⚫Clean the inside of the tank as well as the
outside.
⚫Allow the tank to air-dry completely and
slide it back into place within the
dehumidifier.
⚫After you have replaced the tank, plug the
unit back into its power source.
Warning!!!
Use only mild soap, water and soft cloth. Do not use any commercial cleaning solvents.

17
6.4.2. CONTINUOUS DRAINAGE
Condensate water can be automatically flow into a bucket or drain by gravity with a water hose.
•Set the unit in a horizontal surface and
stable position.
•Switch off the unit before operating.
•Gently take out the water tank from the
dehumidifier.
•Securely and properly connect the drain hose
and make sure it is not kinked and clear of
obstruction.
•Put back the water tank.
•Place the outlet of hose over a drain or
bucket and ensure that water could freely
flow out of the unit.
•Do not submerge the end of hose into
water;otherwiseit can cause "Air Lock" in the
hose.
To avoid water spillage:
•As the negative pressure of condensate
drain pan is large, tilt the drain hose
downward toward the floor.It is appropriate
that the degree of inclination should exceed
20 degrees.
•Straighten the hose to avoid a trap existing
in the hose.

7. CLEANING AND CARE
•CLEANING THE AIR FILTER (every two weeks)
◼The air filter is removable for easy cleaning. Do not operate the unit without an air filter, or the
evaporator may be contaminated. Do not clean the appliance with any chemicals.
Pic1. Switch off the unit and remove air filter.
Warning!!!
Do not touch the evaporatorsurface with
bare-hand, or could cause injury of your
fingers.
Pic2. Rinse the air filter under running water.
Pic3. Re-install the air filter.
