INSTRUCTIONS FOR TECHNICAL PERSONNEL
13
The electrical safety of this equipment is only assured if it is connected as
follows.
It is necessary to connect the equipment to an effective ground installation,
as specified by the electrical safety regulations in force.
Check that this basic requirement is complied with and, in case of doubt, ask
for a careful check of the installation by a qualified personal.
In addition, the equipment shall be part of an equipotential system, the
effectiveness of which should be checked according to the regulations in
force.
The connection should be made at the screw marked by the respective label
located on the equipment back side. ( )
The manufacturer declines any responsibility for any damages caused by lack
of an effective ground installation.
2)WATER CONNECTION
Install a water cock in a well accessible place, terminating in a 3/4" gas
fitting, which the draining pipe shall be connected to.
Carefully comply with any national or regional regulations in force.
The operating pressure should not be less than 2 bar nor greater than 4 bar
(200/400 kPa). In order to get a good result, it is suggested that the feeding
water has an hardness not greater than 5/10°F and a temperature of 55°C -
0+10°C.
3)STEAM FEEDING (*)
As far as steam feeding is concerned, connect to the machine fittings
indicated in the installation drawings. In order to make the equipment
independent from the general steam distribution network, it is necessary to
use gate and 1”gas on/off valves.
This type of feeding should be supplied at a pressure ranging from 0.5bar
(110,8°C-50kPa) to 2bar (132,9°C-200 kPa).
The steam used should be absolutely saturated and dry.
4)WATER DRAIN
Install a water drain at the floor level, complete with siphon, and connect to
the drain through a flexible pipe, making sure that there are no throttlings
along it. Make sure that the draining pipe is resistant at a temperature of
70°C.
