These components are electrical devices. They must be

installed correctly to ensure proper operation and to

prevent shock or fire. Carefully follow all of the installation

instructions and read these important warnings.

• To minimize the danger of fire from sustained electrical

arcing if the heating cable is damaged or improperly

installed, and to comply with the requirements of nVent

and the National Electrical Codes, ground-fault equipment

protection must be used on each heating cable branch

circuit. Arcing may not be stopped by conventional circuit

breakers.

• Component approvals and performance are based on the

use of specified parts only. Do not use substitute parts or

vinyl electrical tape.

• The black heating-cable core is conductive and can short.

It must be properly insulated and kept dry.

• Keep components and heating cable ends dry before and

during installation.

• Damaged bus wires can overheat or short. Do not break bus

wire strands when scoring the jacket or core.

• Bus wires will short if they contact each other. Keep bus

wires separated.

• Heat-damaged components can short. Use a heat gun or

a torch with a soft, yellow flame. Keep the flame moving to

avoid overheating, blistering, or charring the heat-shrinkable

tubes. Avoid heating other components. Replace any

damaged parts.

• Use only fire-resistant insulation materials such as

fiberglass wrap.

• Leave these installation instructions with the user for future

reference.

• Shrink the tube completely. Start at

end farthest from the cap and work

toward the open end.

• Keep heating after tube has shrunk, to melt

adhesive and mastic inside tube. Total heating

time should be about 5 minutes.

Important:

Additional

heat is needed

after the tube is

shrunk to melt

mastic and adhe-

sive inside.

• Immediately after shrinking, pinch the

end of the tube with needle-nose

pliers until the end stays sealed;

this normally takes 10

seconds.

CAUTION: Health Hazard.

Consult material safety

data sheet RAY3122.

CAUTION: To

avoid burns

allow heated

sections to

cool before

touching.

Lay the first piece of aluminum tape as shown.

Ensure the edge of the tape is 1" away from the mastic.

Lay the second piece of tape on the opposite side.

Press and form the aluminum tape onto the heat shrink tube.

Press and form the second piece of the aluminum tape onto

the first piece of the aluminum tape. Ensure the heat shrink

tube is fully covered by the tapes.
