1.2 - Changing the boom from right

with the cubicle positioned on the left looking from behind the gate.
The boom is supplied as a right hand unit.

01. Disengage the balancing spring (step 1 - fig. 4).
02. Hook the balancing spring onto the bottom left (step 2 fig. 4).

motor on the control unit (see enclosed controller instructions).

1.3 - Installing the boom gate
01. Bury the supplied base (fig. 5) in a concrete foundation. This
anchorage o base must be flush with the foundation and peffectly
level; also make one or more, passageways for electric cables. Then
proceed as shown in fig. 7 and 8.
02. Stand the cubicle on the already installed base and anchor it with
the screws and washers provided (fig. 8).
03. Mount the bar using the connection provided and lock it with the
4 screws (fig. 9). Cut any excess bar off.
The vertical and horizontal precision of the bar when it is open or
closed can be adjusted via the shock absorbers with stop (see par.

Nota - Standard bars guarantee a net opening of 4 meters and 6
metres; we recommend using a support for the bar, especially when
the distance is greater than 4 metres.
