1. BEFORE YOU BEGIN
Please read the operating instructions carefully before using your
dehumidifier for the first time.
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 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.
1.2 SYMBOLS FROM THE UNIT AND USER MANUAL
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. SAFETY PRECAUTIONS ON SERVICING
Please follow these warnings when to undertake the following when servicing
a dehumidifier with R290.
2.2.1 Checks to the area
Prior to beginning work on systems containing flammable refrigerants, safety
checks are necessary to ensure that the risk of ignition is minimized. For
repair to the refrigerating system, the following precautions shall be complied
with prior to conducting work on the system.

7
2.2.2 Work procedure
Work shall be undertaken under a controlled procedure so as to minimize the
risk of a flammable gas or vapor being present while the work is being
performed.
2.2.3 General work area
All maintenance staff and others working in the local area shall be instructed
on the nature of work being carried out. Work in confined spaces shall be
avoided. The area around the workspace shall be sectioned off. Ensure that
the conditions within the area have been made safe by control of flammable
material.
2.2.4 Checking for presence of refrigerant
The area shall be checked with an appropriate refrigerant detector prior to
and during work, to ensure the technician is aware of potentially flammable
atmospheres. Ensure that the leak detection equipment being used is suitable
for use with flammable refrigerants, i.e. no sparking, adequately sealed or
intrinsically safe.
2.2.5 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 or CO2 fire extinguisher adjacent to the charging
area.
2.2.6 No ignition sources
No person carrying out work in relation to a refrigeration system which
involves exposing any pipe 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.
2.2.7 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.
2.2.8 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

8
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.
2.2.9 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 are no live electrical components and wiring are exposed while
charging, recovering or purging the system;
-that there is continuity of earth bonding

●Securely and properly connect the drain hose and make sure it is not
kinked and clear of obstruction.
●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; otherwise it can cause "Air
Lock" in the hose.
%%%%%%%%%%%%%%%%%%%%% %
6.2 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.%
•CLEANING THE AIR FILTER (every two weeks)
Dust collects on the filter and restricts the airflow. The restricted airflow
reduces the efficiency of the system and if it becomes blocked it can
