Hanging panel

Hanging panel with water valve

Hanging panel without water valve

Two types of hanging panel are available: one is for use in
installations with a water valve and the other without.

Hanging panel with water valve

The panel contains:

water shut-off valves with 1/2” female gas threaded fitting for
connection to the water system;

thermo-electric valve piloted by the room thermostat control;

printed circuit for electrical connections;

unit support chain; this permits the unit to be swung downwards
through 90

°

 facilitating installation;

flexible pipes with threaded fitting for the unit hydraulic connection;

control.

The system side hydraulic connections are made inside the
hanging panel, using the 1/2” female gas threaded fitting of the
shut-off valves.
The unit is then connected to the valve group using the flexible
pipes supplied in the hanging panel.

Hanging panel without water valve

The panel contains:

printed circuit for electrical connections;

unit support chain; this permits the unit to be swung downwards
through 90

°

 facilitating installation;

 

telescopic extensions;

side closing plugs;

control;

The water connections are made using the copper pipes supplied
with the unit and fitted with 3/8” male gas threaded fittings.

If the installation foresees the use of side closing plugs 

,

fix them with the screws supplied (ref. a) before hanging the panel
on the wall.

If you use the telescopic extensions 

 

 make sure that these close

against the wall.
