DESCRIPTION

The nVent RAYCHEM PMK-JLP-M is a Type 4X-rated power

connection kit designed for use with RAYCHEM BTV-MCT, QTVR-MCT

and XTV-MCT industrial parallel monitor wire heating cables. This kit

may be installed at temperatures as low as –40°F (–40°C). For easier

installation store above freezing until just before installation.

For technical support call nVent at (800)545-6258.

TOOLS REQUIRED

• Wire strippers • Heat gun or propane torch

• Diagonal cutters • Utility knife

• Needle-nose pliers

• Flatblade screwdrivers, 1/8 & 1/4 inch

ADDITIONAL MATERIALS REQUIRED

• 1 Grommet (see selection chart on page 2)

• 1 Pipe strap (order separately)

• Glass cloth tape

- GT-66 Installation temperature above 40°F (4°C)

- GS-54 Installation temperature above -40°F (-40°C)

This component is an electrical device that must be installed

correctly to ensure proper operation and to prevent shock or

fire. Read these important warnings and carefully follow all of

the installation instructions.

• 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,

agency certifications, and national electrical codes, ground-

fault equipment protection must be used. Arcing may not

be stopped conventional circuit breakers.

• Approvals and performance are based on the use of nVent-

specified parts only. Do not use substitute parts or vinyl

electrical tape.

• The black heating cable core and fibers are conductive and

can short. They must be properly insulated and kept dry.

• Connection kits and heating cable ends must be kept dry

before and during installation.

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

bus wire strands when scoring the jacket orcore.

• Use only fire-resistant insulation materials, such as

fiberglass wrap or flame-retardant foam.

•

Heat damaged components can short. Use a heat gun or

torch with a soft, yellow, low-heat flame. Keep the flame

moving to avoid overheating, blistering, or charring the heat-

shrinkable tubes. Avoid heating other components. Replace

any damaged parts.

HEALTH HAZARD: Over heating heat-shrinkable tubes

will produce fumes that may cause irritation. Use adequate

ventilation and avoid charring or burning. Consult MSDS

RAY3122 for further information.

• Determine correct grommet (order separately) from

chartbelow.

WARNING: Use of the wrong grommet can result in

leaks, cracked components, shock or fire, and will

invalidate approvals and certifications.

that 1 in. (25 mm) of

heating cable outer

jacket extends past

top of threads.

• Tighten screws.

Pipe strap

• Fasten base to pipe with

strap.

• Loop and tape extra

heating cable to pipe.

• Install sealing ring.

• Install box with locknut.

Instructions for Using a Heat Gun or Torch:

• Read important warnings on Page 1 and follow safety

precautions provided with heat gun or torch.

• When using a torch use a soft yellow, low-heat flame. Apply

just enough heat to do the job.

• Keep torch or heat gun moving continuously to distribute the

heat evenly to avoid overheating, blistering or charring the

heating cable and heat-shrinkable tubes.

• Replace any heat-damaged parts.

• Slide two black

tubes onto bus

wires and green/

yellow tube onto

braid.

1/2 in

(13 mm)

• Center clear yellow tube over end of base jacket.

• Heat tube until it shrinks and adhesive flows out ends.

While still hot, pinch between wires and hold for 5 seconds.

• Use a heat gun or propane torch to heat tubes until they

are fully recovered.

Note: See Step 15 for proper heating

techniques.
