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 R32 is used as the refrigerant. R32 has no
damaging influence on the ozone layer (ODP), a negligible greenhouse effect
(GWP) and is available worldwide. Because of its efficient energy properties,
R32 is highly suitable as a coolant for this application. Special precautions must
be taken into consideration due to the coolant's high flammability.
6

2.2 SAFETY PRECAUTIONS ON SERVICING
Please follow these warnings when to undertake the following when
servicing an appliance with R32.
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.
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 work space 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.
13
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
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;
14
– 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 no live electrical components and wiring are exposed while
charging, recovering or purging the system;
-that there is continuity of earth bonding.
WARNING!
Install the unit in rooms which exceed 8 m².
Do not install the unit in a place where inflammable gas may
leak.
NOTE!
The manufacture may provide other suitable example or may
provide additional information about the refrigerant odour.
