Raychem h910 Installation Instructions 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.
