▷
We recommend preparing the connection boxes
before the double solenoid valve is installed in
the pipework. Alternatively, one of the actua-
tors must be dismantled as described below
and reinstalled rotated by 90° in preparation for
installation of the double solenoid valve.
▷ The cable gland set can only be used if the con-
nection boxes are at the same height and on
the same side.
1 Disconnect the system from the electrical power
supply.
Shut off the gas supply.

In both connection boxes, push through the
knock-out for the cable gland set – then remove
the covers. The covers must not be taken off
before pushing through the knock-outs as it pre-
vents damage to the connection boxes.
