Raychem h910 User manual

Description
The WinterGard H910 Splice and Tee Kit is for use with WinterGard
self-regulating heating cables to make splice, tee, and end seal
connections. The kit contains materials for one splice and one end
seal, or one tee connection and one end seal. This kit does not
provide a power connection; use an H900, H908, or H911 power
connection kit for complete installation.
Applications
Use the H910 kit with the following WinterGard heating cables:
H311, H611, H612, H621, and H622. All are designed for pipe
freeze protection in dry locations, but H612 and H622 cables are
designed for both wet and dry areas, as well as for roof and gutter
de-icing. The cable type is printed on the outer jacket of the cable.
Installation and Support
The minimum installation temperature for this kit is 0°F (–18°C).
See the WinterGard Application and Design Guide (H53585) or the
H900, H908, or H911 installation instructions for design information.

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 Raychem and the 1996
National Electrical Code, ground-fault equipment
protection must be used on each heating cable
branch circuit. Arcing may not be stopped by
conventional circuit protection.
•Component approvals and performance are
based on the use of specified parts only. Do
not substitute parts or use 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 braid or 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,
low-heat flame, not a blue focused 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.
Charring or burning the heat-shrinkable tubes
in this kit will produce fumes that may cause
eye, skin, nose and throat irritation. Consult
Material Safety Data Sheet RAY/3122.
