Important Safeguards and Warnings
WARNING: FIRE AND SHOCK HAZARD
nVent RAYCHEM HWAT Systems must be installed correctly to ensure
proper operation and to prevent shock and fire. Read these important
warnings and carefully follow all 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 nVent requirements, agency certifications, and 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.
•Approvals and performance are based on the use of nVent parts
only. Do not substitute parts or use vinyl electrical tape.
•Bus wires will short if they contact each other. Keep bus wires
separated.
•Connection kits and heating cable ends must be kept dry before and
during installation.
•The black heating cable core is conductive and can short. They must
be properly insulated and kept dry.
•Damaged bus wires can overheat or short. Do not break bus wire
strands when preparing the cable for connection.
•Damaged heating cable can cause electrical arcing or fire. Do not
use metal attachments such as pipe straps or tie wire. Use only
nVent-approved tapes and cable ties to secure the cable to the pipe.
•Do not attempt to repair or energize damaged cable. Remove
damaged cable at once and replace with a new length using the
nVent RayClic-S splice kit. Replace damaged connection kits.
•Use only fire-resistant insulation which is compatible with the
application and the maximum exposure temperature of the system
to be traced.
