6. Check the continuity of the heat tapes.
a. Use an ohmmeter to check the electrical
resistance of the two outer prongs of the
connector (D) that attaches to the heated hose
control. See Fig. 3. The resistance for the
various lengths of coupled hose assemblies is
given in the following coupled hose chart.
Coupled Hose Length
315 feet (96 m)
215 feet (66 m)
115 feet (35 m)
65 feet
(20 m)
50 feet
(15.2 m)
b. Between the middle and outer prong of the
connector, the resistance should be more than
1 megohm. If it is less, there is a fault in one of
the connectors (D) or the heat tapes, which
will cause the Ground Fault Interrupter of the
Foam-Cat Heater hose control to shut off
electric power to the hose. If there is a fault,
check each 50 foot (15.2 m) hose section
individually and replace the faulty section.
c. Check the continuity of the middle prong of the
connector (D) from one end of the coupled
hoses to the other. The resistance should be
less than 10 ohms.
d. Check the continuity of the whip hose between
the two outer prongs and then between the outer
and middle prongs of the exposed connector as
instructed in steps 6a. and 6b. The resistance
between the outer prongs should be 300 to 400
ohms.

7. Connect the whip hose to the main hose assembly.
a. Connect the corresponding fluid hoses.
b. Connect the hose electrical connector to the
control box cable.
c. Connect the air hoses. Do not alter the air
hose length at this connection. Loop it down
from the gun as shown in Fig. 4.

8. Check all hose connections to be sure they are
securely tightened.
9. Connect the main hose(s) to the heater and the
whip hose to the gun.
10. Ground the system.
WARNING
FIRE, EXPLOSION, AND ELECTRIC
SHOCK HAZARD
Before operating the system, ground it
as explained in your separate compo-
nent manuals and local code. Also read
the section FIRE, EXPLOSION, AND
ELECTRIC SHOCK HAZARD, page 4.
The Foam-Cat Heated Hose is grounded through
connection to a properly grounded Foam-Cat
Heater. In a mobile installation, be sure the truck
or trailer is grounded to a true earth ground.
In Europe, the hose continuity must comply with
VDE 0100.
