cal attention.
D Do not point the spray gun at anyone or at any part of the body.
D Do not put your hand or fingers over the spray tip/nozzle.
D Do not stop or deflect leaks with your hand, body, glove or rag.
D Do not “blow back” fluid; this is not an air spray system.
D Always have the trigger guard on the spray gun when spraying.
D Be sure the gun trigger safety operates before spraying.
D Lock the gun trigger safety when you stop spraying.
D Follow the Pressure Relief Procedure on page 9 whenever you: are instructed to relieve pres-
sure; stop spraying; clean, check, or service the equipment; and install or clean the spray tip/

Installation
Each hose assembly is 50 feet (15 m) long. A maximum combined length of 300 feet (92 m) can be used,
in addition to a 15 foot (4.6 m) whip hose assembly.
The whip hose assembly is smaller in diameter, which
makes maneuvering the hose easier for the operator.
The fluid hoses are marked ISO or RES and are
oppositely coupled to prevent incorrect connection,
which can cause fluid crossover and permanently
damage the hose. Refer to Fig. 1.
WARNING
ELECTRIC SHOCK HAZARD
Strain on the heat tape wires can pull
them loose from the connectors when
the hose is moved or coiled. To reduce
the risk of an electric shock from loose or damaged
wires, follow these precautions.
D Make the bend in the heat tape as instructed
below.
D Do not wrap the heat tape around the hoses.
Connecting the 50 foot (15.2 m) Hoses
a. Slide the male end of the sleeve (A) over the
hose (B).
b. Grease the barbed end of the stud (C) and
push it into the hose until it seats properly.
c. Tighten the sleeve until it bottoms on the
fitting.

Resistance Range
11–15 ohms
20–25 ohms
37–46 ohms
65–80 ohms
84–124 ohms
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.
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.

Installation
WARNING
INJECTION HAZARD
To reduce the risk of serious injury,
follow the Pressure Relief Procedure
on page 9 whenever you are instructed
to relieve pressure.
11. Pressure check the hose assemblies. Refer to the
heater manual 308219 for priming and pressurizing
the fluid hoses. Check carefully for leaks at the
hose connections. If there are leaks, relieve the
pressure as instructed on page 9. Tighten the
connections, then pressurize the sprayer and
hoses again to make sure the leaks have stopped.
Shut off the sprayer and relieve the pressure.
12. Insulate the hose connections.
a. Wrap electrical tape securely around the fluid
and air hose connectors only, so the sharp
metal edges of the connectors cannot damage
the plastic connectors of the heat tapes. See
Fig. 5.
b. Tape the heat tape connectors together sepa-
rately to help prevent the connectors from
pulling apart. Then tape the heat tape connectors to the air and fluid hose connectors; leave
the wires free to move slightly to prevent strain
on the wires at the connectors. See Fig. 6.
c. Wrap the insulation tubing (E) around the hose
connections, overlapping at the seam. See
Fig. 7. Wrap the tape (F) continuously around
the tubing, beginning and ending about 2 inches
(51 mm) past the slit in the insulation.

Operation and Maintenance
Pressure Relief Procedure
WARNING
INJECTION HAZARD
The system pressure must be manually
relieved to prevent the system from
starting or spraying accidentally. Fluid
under high pressure can be injected through the
skin and cause serious injury. To reduce the risk of
an injury from injection, splashing fluid, or moving
parts, follow the Pressure Relief Procedure
whenever you:
D are instructed to relieve the pressure,
D stop spraying,
D check or service any of the system equipment,
D or install or clean the spray tip/nozzle.
1. Lock the gun trigger safety.
2. Shut off the air to the feed pumps.
9. If you suspect that the spray tip/nozzle or hose is
completely clogged, or that pressure has not been
fully relieved after following the steps above, very
slowly loosen the tip/nozzle retaining nut or hose
end coupling to relieve pressure gradually, then
loosen completely. Wear protective gloves to avoid
skin injection or burns. Now clear the tip/nozzle or
hose.
10. Be sure the fluid is cool before disconnecting the
hoses.
Operation
WARNING
INJECTION HAZARD
Never operate the hose when it is coiled.
A coiled hose creates excessive heat
buildup which can result in hose rupture
and cause serious injury, including injection. The
high heat can also cause poor foam development.
Refer to your system manual for complete startup and
operating instructions.
3. Turn off the power (air or electric motor switch) to
the proportioning pump.
4. Close the gun manifold fluid valves.
5. Unlock the spray gun trigger safety.
6. Hold a metal part of the gun firmly to the side of a
grounded metal pail, then trigger the gun to relieve
pressure.
7. Lock the trigger safety again.
8. Open both fluid filter drain valves; have a container
ready to catch the draining fluid.
Maintenance
WARNING
INJECTION HAZARD
Do not mend or repair any part of a hose
assembly. If the hose is damaged,
replace it immediately to avoid serious
injury from fluid injection and electric shock.
If a section of hose is not heating, be sure the connector at the hose control box is firmly plugged in. If that
does not correct the problem, relieve the fluid pressure
in the sprayer and hoses, as instructed at left. Remove
the abrasion cover and the insulation tubing on each
end of the hose in question. Make sure the heat tape
connections are secure and repeat the continuity
check in Step 6, page 6. If the hose is faulty or the
problem not corrected, replace the hose.
