6. DEVICE INSTALLATION ___________________________________________
NOTE
During the installation of valve and the finishing works, take into account the possibility of
access to the device later and the disassembly of release and control mechanism in order to
carry out the possible service works and technical inspections.
The mcr ZIPP valve can be installed in the following partitions (walls or ceilings):
masonry walls – concrete with a thickness of at least 110 mm
masonry walls from bricks or blocks at least 120 mm thick
walls from panels at least 125 thick
ceilings of at least 150 mm
Additionally, the valve can be installed:
outside walls
in batteries (multiple sets)
The mcr ZIPP shut-off valve may also be installed in partitions with lower fire resistance class In case of such an
installation, valves have fire protection equal to the fire protection of the partition, maintaining the smoke tightness
criteria.
