The hoses receive vacuum drying treatment and are supplied interconnected at the ends to
prevent them from absorbing moisture. Do not separate them until they are going to be installed
in the unit.
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.
f)
Connect the heated hoses wires to the “fast
lock” connector coming out of the hose
transformers 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
NB:
A good practice is to add some dielectric grease to the ID of the connector.
Repeat the same steps to connect the “fast lock” that you will find in the middle hose
connections
g) Connect the rest of the product hoses to complete the required length. Remember that
the hoses are identified with red (Isocyanate) and blue (Polyol).
NB:
Assure the proper mechanical and electrical connection of the hoses to avoid
possible product leakage and hose heat problems.
