Important Safety Information
READ AND FOLLOW ALL SAFETY INSTRUCTIONS
Transport of equipment containing flammable
refrigerants:
See transport regulations.
Marking of equipment using signs:
See local regulations.
Disposal of equipment using flammable
refrigerants:
See national regulations.
Storage of equipment / appliances:
The storage of equipment should be in accordance with the
manufacturer's instructions.
Storage of packed (unsold) equipment:
Storage package protection should be constructed such that
the mechanical damage to the equipment inside the package
will not cause a leak of the refrigerant charge. The maximum
number of pieces of equipment permitted to be stored together
will be determined by local regulations.
Information on servicing
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. Work procedure: Work shall be undertaken under a
controlled procedure so as to minimize the risk of a
flammable gas or vapour being present while the work is
being performed.
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 work
area have been made safe by removing all flammable
material.
4. Checking for the 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. non-sparking,
adequately sealed and intrinsically safe.
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 C0
extinguisher adjacent to the work area.
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 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 there are no flammable hazards or ignition risks. No
smoking signs shall be displayed.
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 preferable expel it externally into the
atmosphere.
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 become illegible must
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 suitable protected against being
corroded.
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
