2. Appliance shall be installed, operated and stored in a room with a floor area larger than 4m 2 .
3. The installation of pipe-work shall be kept to a minimum.
4. The pipe-work shall be protected from physical damage, and shall not be installed in an unventilated space if
the space is smaller than 4m 2 .
5. The compliance with national gas regulations shall be observed.
6. The mechanical connections shall be accessible for maintenance purposes.
7. Follow the instructions given in this manual for handling, installing, cleaning, maintaining and disposing of the

an operating gas appliance) and ignition sources (for example an operating electric heater).
12. The appliance shall be stored so as to prevent mechanical damage from occurring.
13. It is appropriate that anyone who is called upon to work on a refrigerant circuit should hold a valid and up-to-
date certificate from an assessment authority accredited by the industry and recognizing their competence
to handle refrigerants, in accordance with the assessment specification recognized in the industrial sector
concerned. Service operations should only be carried out in accordance with the recommendations of the

16. 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 workspace shall be sectioned off.
Ensure that the conditions within the area have been made safe by control of flammable material.
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. non-sparking, adequately sealed or 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
