PART III: OPERATION

Multibloc MB-DLE
The multibloc unit is a compact unit consisting of two valves, gas pressure switch, pres-
sure stabilizer and gas filter.
The valve is adjusted by means of the
RP
regulator after slackening the locking screw
VB
by a number of turns. By unscrewing the regulator
RP
the valve opens, screwing the valve
closes. To set the fast opening remove cover
T
, reverse it upside down and use it as a tool
to rotate screw
VR
. Clockwise rotation reduces start flow rate, anticlockwise rotation incre-
ases it.
Do not use a screwdriver on the screw
VR
!
The pressure stabilizer is adjusted by operating the screw
VS
located under the cover
C
.
By screwing down the pressure is increased and by unscrewing it is reduced.
Note: the screw
VSB
must be removed only in case of replacemente of the coil.
