This heat pump contains R32 flammable refrigerant.
Prior approval must be obtained before any procedure is performed on the refrig-
erant circuit.
To ensure user safety, the following precautions must be followed before any procedure is
performed on the refrigerant circuit.
1. Work procedure
All work must be carried out in accordance with strict guidelines in order to minimise the risk of gas or
flammable vapour escaping during the execution of the work.
2. General workplace conditions
All persons present in the work area must be informed as to the nature of the work being carried out. Avoid
performing work in confined spaces. The area surrounding the work space must be cordoned off and
particular attention must be paid to nearby sources of heat or flames.
3. Monitoring the presence of refrigerant
The area must be monitored for the presence of refrigerant, using an appropriate detector, before and
after any work takes place in order to ensure that no potentially flammable gas has escaped. Ensure the
equipment used for detecting leaks is suitable for flammable refrigerants, i.e., does not generate sparks,
the device is properly sealed or equipped with internal safety measures.
4. Fire extinguishers
If hot work is being performed on the refrigeration system, or any related system, appropriate fire extin-
guishing equipment must be available. Install a dry powder or CO2 fire extinguisher near the work area.
5. No sources of heat, open flames or sparks
The presence of heat sources, open flames or sparks in close proximity to one or more parts/pipework
containing or having contained flammable refrigerant is strictly prohibited. All sources of sparks, including
smoking, must be located sufficiently far away from the site of installation, repairs, removal and disposal,
during which flammable refrigerant could escape into the surrounding environment. Before beginning
work, the environment surrounding the equipment must be verified to ensure there is no source of ignition.
"No smoking" signs must be displayed.
6. Ventilated area
Ensure that the workplace is open to the air, or properly ventilated, before performing any work on the
system or carrying out hot work. Sufficient ventilation must be maintained throughout the period of work.
7. Inspection of refrigeration equipment
When electrical components are replaced, they must be suitable for their intended use and meet the rele-
vant specifications. Replacements must be genuine or OEM parts. If in doubt, contact the manufacturer's
customer support team.
Inspections must be performed on installations using flammable refrigerants:
– Refrigerant charge must be appropriate for the size of the space in which the refrigeration system is
installed..
– The ventilation system and air vents must function correctly and must not be obstructed.
– If an indirect refrigeration system is being used, the secondary circuit must also be inspected.
– Equipment markings must be clearly visible and legible. Illegible signs and markings must be corrected.
– Refrigerant pipework and components must be installed in locations with no risk of exposure to sub-
stances capable of corroding components containing refrigerant fluid.
8. Inspection of electrical appliances
Repairs and maintenance performed on electrical appliances must include preliminary safety tests and in-
spection of components. In the event a fault is detected which is capable of compromising safety, electrical
power must be disconnected from the circuit until the problem is resolved.
Preliminary safety tests must include the following:
• Ensuring the condensers are fully discharged: this must performed in a safe manner to avoid the risk of
ignition;
• Ensuring that no wires or electrical components are exposed at the time of charging, recovery, or purging
the system of refrigerant gas.
• Ground continuity test.
