Important Safeguards and Warnings
WARNING: FIRE AND SHOCK HAZARD
Raychem HWAT Systems must be installed correctly to ensure proper
operation and to prevent shock and fire. Read these important warn-
ings 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 Pentair Thermal Management requirements, agency certifica-
tions, and national electrical codes, ground-fault equipment protec-
tion 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 Pentair
Thermal Management 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
Pentair Thermal Management 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
Raychem 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.
