2. Insulate the hose connections.
a. Wrap electrical tape securely around the
fluid and air hose connectors only, so the
shart metal edges of the connectors cannot
damage the plastic connectors of the heat
tapes. See Figure 5.
b. 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 Figure 6.
c. Wrap the insulation tubing (E) around the
hose connections, overlapping at the seam.
See Figure 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
Pressure Relief Procedure
Always relieve the fluid pressure in the sprayer
and hoses before checking or adjusting any part
of the system or any component, to reduce the
risk of serious bodily injury, including fluid
injection, splashing in the eyes or on the skin, or
injury from moving parts or electric shock.
1. Engage the spray gun trigger safety latch.
2. Shut off the air to the feed pumps.
3. Turn off the air to the proportioning pump.
4. Close the gun manifold needle valves.
5. Disengage the trigger safety latch, trigger the
gun, to relieve pressure, and engage the
trigger safety again.
6. Open both fluid filter drain valves, having a
container ready to catch the draining fluid.
7. If you are working on any part of the heater,
shut off the main electrical power to the

t
To reduce the risk of serious injury, including fluid
injection or electric shock:
Do not use the heated hoses for
spraying without the insulation
tubing in place (see step 12) and
the abrasioncover installed (see
step 13).
Replace the insulation immediately
if any portions of it are worn away.
WARNING
Wrap hose connections with electrical tape
Tape heat tape connectors to hose
connections with electrical tape
