|Warnings (for using R290/R32 refrigerant only)
1. Transport of equipment containing
flammable refrigerants See transport
regulations
2. Marking of equipment using signs See local
regulations
3. Disposal of equipment using flammable
refrigerants See national regulations.
4. Storage of equipment/appliances
The storage of equipment should be in
accordance as per the user's manual.
5. Storage of packed (unsold) equipment
The storage of the package should be
constructed in such a manner that if any
mechanical damage to the equipment will
not result ina leak of the refrigerant.
6. Information on Servicing
1) Checking the area
Upon initial work, regarding systems
containing flammable refrigerants,
mandatory safety checks are required to
ensure that the risk of possible ignition is
minimized. Prior to any repairing to the
refrigerant system, the following
2) Work procedure
Any handling should be performed under a
controlled procedure as to minimize the risk
of flammable gas being present while work
is being performed.
3) General work area
All relative maintenance staff and all others
working in the area, should be clearly
instructed, on the nature of the procedure.
Any maintenance in confined spaces must be
avoided. The space around the work-area
should be securely sectioned off. Confirm that
the conditions within the area, are safe and
the flammable material is controlled.
4) Prior to and during work operation, the
area should be checked and monitored by an
appropriate refrigerant detector, also ensuring
the technicians to be aware of potentially
flammable materials in the atmosphere. It is
very important that the refrigerant detector
being used is suitable for the usage with
flammable refrigerants.
5)Presence of fire extinguisher
If any work that involves heat, is to be
conducted, the appropriate fire extinguishing
equipment should be always available. A dry
powder or CO2 fire extinguisher should be
available adjacent to the charging area.

6) No ignition sources
Work that is in relation to a refrigeration system
which involves exposing any pipe works that
contains or has contained flammable refrigerant
gases should be carried out be
no persons, as they may lead to the risk of a
fire.All possible fire hazards such as cigarette
smoking, must be kept far away from the site
of repair,installation removing and or
disposal, where the possibility of refrigerant
gas may be released to the atmosphere.
Prior to the performance of any work
conducted, the area around the equipment
should be monitored and checked to be
certain that no flammable hazards or ignition
risks are present. NO SMOKING signs are
mandatory and must be displayed..
7) Ventilated area
Prior to any work performed, be certain that
the area is well ventilated or open. Constant
ventilation while any work is carried out is
necessary. Ventilation should safely disperse
any possible refrigerant leak externally into
the atmosphere.
8) Checks to the refrigeration equipment
Where electrical components are being
changed, they should be fit for purpose and
with the correct specifications. Manufacturer's
maintenance and Service Guidelines should
be followed at all times. If there is any doubt,
please consult with the manufacturer's
Technical Debt for assistance. The following
checks should always be performed in regard
to installations using flammable refrigerants:
The charge size is in accordance with the room
size, in which the refrigerant parts are installed.
Be certain the ventilation is operative and check
the outlets do not have any obstructions.
If there is a use of an indirect refrigerant circuit,
this secondary circuit should be checked for any
refrigerant being present. Any markings to the
equipment should be clear and visible.
Markings and signs that are not clear should be
corrected. Any refrigeration pipe or components
should be installed in such a manner as to
never be exposed to any substance that may
lead to the corrosion of the refrigerant
containing components, unless these
components are designed as resistant to
possible corrosion, or are corroded resistant.
