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 connec-
tors 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.
NOTE:
Standard black electrical tape can be used if
additional tape is needed to secure the tubing.
WARNING
To reduce the risk of serious injury, including fluid
injection or electric shock:
D
Do not use the heated hoses for spray-
ing without the insulation tubing in
place (see Step 12) and the abrasion
cover installed (see Step 13).
D
Replace the insulation immediately if
any portions of it are worn away.
