10. Connect the feed hose to the displacement
pumps.
Slide an identification band (ISO or
RES) over the end of each feed hose (45).
Connect a feed hose between the feed pump
fluid outlet (46) and the 3/4" npt (f) fluid intake
valve (202) of each displacement pump (48).
Refer to the Typical Installation on page 5.
11. Remove the ATC Sensor (49) from the clamp
(50) and locate it outside in air that is typical of
the surface to be sprayed. The sensor has a
50' (4.6 m) cable. See Figure 6, page 8.
WARNING
The electrical wiring should be done only by
trained and qualified personnel to reduce the
risk of serious bodily injury and electric shock.
Observe
all
local
regarding electrical wiring.
13. Wire the electrical service to the heater junction
box. The electrical requirements for the heater
are shown on the inside cover to the heater
junction box.
The heater is grounded through the electrical
wiring to a grounding screw on the inside
bottom of the junction box. The proportioning
pump must also be grounded to provide
adequate system electrical grounding. Refer to
Step 14.

connection to a properly grounded 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
VDC 0100.
To ground the pumps and sprayer:
a. Loosen the grounding lug locknut (55)
and washer (52) located on the
proportioning pump motor (48). Insert
one end of a 12 ga (1.5 mm²)
minimum ground wire (53) into the slot
in the lug (54) and tighten the locknut
securely. See Figure 6.
b. Connect the other end of the wire to a
good ground such as a steel building
column (check you local code).

installation, be sure the truck or trailer
is connected to a true earthen ground.
d. Connect the heated hose to a properly
grounded heater. The Ground Fault
Interrupter on the hose control panel of
the Foam-Cat Heater senses electrical
continuity in the heated hoses; it cannot
function unless the heater is positively
grounded. In Europe, hose continuity
must comply with VDE 0100.
