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.
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 R134a is used as the refrigerant. R134a has no damaging influence on
the ozone layer (ODP), a negligible greenhouse effect (GWP) and is available worldwide. Because
of its efficient energy properties, R134a is highly suitable as a coolant for this application.
Special precautions must be taken into consideration due to the coolant's high flammability.

2.2 SAFETY PRECAUTIONS ON SERVICING
Please follow these warnings when to undertake the following when servicing a dehumidifier
with R134a.
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.
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.
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.
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.
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 CO2fire extinguisher
adjacent to the charging area.
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.
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.

⑧Checks to the refrigeration equipment
⑨Checks to electrical devices
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.
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.
