Preparation (units with heated hose & transformer)
Each section of heated hose set features one connector for supply voltage and one connector
for TCS temperature control.
WARNING!
Use suitable protective gear and follow the safety recommendations of the
suppliers of the chemical components when preparing or working with the unit.
NOTE:
To ensure the correct operation of the unit, the electrical power supply must
meet the specifications given on p 7 of this manual a
nd on the unit’s rating plate.
The hose connection
system includes special
terminals (fast lock) to
facilitate the electrical
connection
to
the
transformer
and
between the different
sections installed in the
unit.
The transformer offers
the option of connecting
to a 40 V output voltage
valid for a total hose
length of up to 48
meters (158 ft), or an
output voltage of 75 V,
for
hose
lengths
exceeding 48 meters
(158 ft) to 93 meters
(305 ft). Connect to one
output voltage or the
other depending on the
total
hose
length
installed. Before starting up the unit, make sure that the
connection made in the factory adapts to the total length
of hose installed. If you add or eliminate sections of
hose, make sure the output voltage of the transformer
to which it is connected is suitable for the resulting total
length. Otherwise, change the connection.
a) Connect
the
power
cables
(fast
lock
connectors) of the heating hoses on the front
side of the electrical transformer as follow:
a. Unscrew the Nylon Safety Plug from
the “fast lock” connector body.
b. Unscrew partially the Socket Head Set
Screw from electrical wires.
c. Insert the heated hose electrical wire
with terminals into the “fast lock” connector body.
d. Tighten the Socket Head Set Screw of the terminals and place the Nylon Safety
Plugs.
