under the supervision of the person competent in the use of flammable refrigerants.
If you do not understand something or need help, please contact the dealer services
2.2 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 should be complied with prior to conducting work on the system.
2.2.2 Work procedure
Work should be undertaken under a controlled procedure 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 should be instructed on the nature of
work being carried out. Work in confined spaces should be avoided. The area around the
workspace should 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 should 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.

6
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 should 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
pipework that contains or has contained flammable refrigerant should 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 should 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 should 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 should be fit for the purpose and to the
correct specification. At all times, the manufacturer’s maintenance and service guidelines should
be followed. If in doubt consult the manufacturer’s technical department for assistance.
The following checks should 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 should be checked for the
presence of refrigerant.
– Marking to the equipment continues to be visible and legible. Markings and signs that are
illegible should be corrected.

Front shell
– 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 should include initial safety checks and
component inspection procedures. If a fault exists that could compromise safety, then no
electrical supply should 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 should be used. This should be reported to the owner of the equipment, so
all parties are advised.
Initial safety checks should include:
-those capacitors are discharged: this should 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
