Introduction
Each hose assembly must be controlled by a Graco
zone controller. The amount of hose used depends on
the zone controllers available for control.
The hose has two electrical connectors with cables,
each extending from the end of the hose.
The large rectangular connector is the machine end
and has 8 foot (2.42 m) of cable (see Fig. 1). The
small square connector is the gun end and has 2 foot
(0.6 m) of cable (see Fig. 2).
PH00051
Fig. 2
Connect the machine end connector to the Graco
temperature controller by pushing the connector on the
mating receptacle of the temperature controller or
accessory device and securing the latch.
Connect the gun end connector to any temperature
controller accessory device. These include Graco
manual and automatic hot melt dispense valves,
pressure compensators, manifolds, headers, and
pressure regulators.

Operation
WARNING
WARNING
This equipment should not be used with
more than one type of fluid due to poten-
tial compatibility issues which could
result in an unpredictable reaction.
Graco recommends using new hoses
when chemicals are changed or care
SKIN INJECTION HAZARD
The system pressure must be manually
relieved to prevent the system from
starting or dispensing 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:

Operate at lowest possible temperature and
pressure necessary for application.
1. Lock the gun trigger safety.
Hose must be vented during startup and shut-
down.
The dispense valve must be kept open over a
waste container while the system is heating up
and also when cooling down. This will prevent a
pressure build–up caused by fluids or gasses
expanding from the heat.
2. Shut off the air to the supply pumps.
3. Turn off the power (air) to the proportioning pump.
4. Unlock the spray gun trigger safety.
Refer to your system operation manual for complete
startup and operating instructions.
5. Hold a metal part of the gun firmly to the side of a
grounded metal pail, then trigger the gun to relieve
pressure.
Maintenance
WARNING
SKIN 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.
7. If you suspect that the dispense valve or hose is
completely clogged, or that pressure has not been
fully relieved after following the steps above, very
slowly loosen the tip 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.
If the 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
pump and hoses, as instructed at left. If the hose is
faulty or the problem not corrected, replace the hose.
See Troubleshooting on page 8 for electrical mea-
surements.
8. Be sure the fluid is cool before disconnecting the
hoses.
