Before starting to arm the valve with the release and control mechanism of RST+EK type, make sure that the
electromagnet operates correctly. In order to do so:
-
plug the electrical wires into the terminal block (according to point 6.5.)
-
carefully clean the contact surfaces
and connect the plate with the electromagnet
-
apply the signal that initialises the electromagnet release – supply voltage with the relevant value (after the
initialising signal, the plate should detach from the electromagnet)
In order to arm the RST+EK release and control mechanism, the following actions have to be taken:
-
screw the valve from the connection stub pipe
-
in the case of the RST+EKP mechanism (controlling via the "current gap"), plug all electric wires into
the terminal block (in accordance with point 6.5.) and enable the electromagnet power supply.
-
in the case of the RST+EKI mechanism (controlling via the "current impulse"), plug all electric wires
into the terminal block (in accordance with point 6.5.) and without enabling the electromagnet power
supply.
-
Connect the plate with the electromagnet
-
rotate the valve so that the mushroom is on top
-
simultaneously release the locking sheet and press the valve nozzle at its circumference (fig. 4a)
-
push the fuse element onto the catches (fig. 2)
6.2. FIXING HOLE___________________________________________________________
Minimum diameter of the hole that allows correct installation of the mcr ZIPP valve equals:
- D + 22 – in the case of a wall made of plasterboards
- D + 40 – in the case of concrete, masonry and ceiling partitions
6.3. EMBEDDING / SETTING THE VALVE
INSTALLATION IN A CONCRETE OR MASONRY WALL
In the fixing hole, set the connection stub pipe with bent expansion sheets, so that the stub pipe axis is lined up
with the hole axis. The gap between the stub pipe and the hole edge should be tightly packed with mortar or
another material that provides the required fire resistance (fig. 5a). In case of installation through the wall to the
duct, concurrently set the connection stub pipe and the extension stub pipe (figs 5b, 5c).
In rigid walls and ceiling
In light plasterboards walls
