WARNING:
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 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 Pentair Thermal Management,
agency certifications, and national electrical codes, ground-
fault equipment protection must be used. Arcing may not be
THERMAL BUILDING SOLUTIONS
stopped by conventional circuit breakers. The ECW-GF provides
the required ground-fault equipment protection.
• The ECW-GF must be effectively grounded to ensure proper
operation. Do not rely on the conduit system to provide a ground
path. Use the grounding terminals/screws to connect to system
ground leads.
• Component approvals and performance are based on the use of
Pentair Thermal Management-specified parts only. Do not use
substitute parts or vinyl electrical tape.

DESCRIPTION
The Raychem ECW-GF is an electronic ambient, pipe, or slab sensing
controller with 30-mA ground-fault protection. It is ideal for pipe
freeze protection, flow maintenance, freezer frost heave and snow
melting applications. The controller can be programmed to maintain
temperatures up to 200°F (93°C) at voltages from 100 to 277 V and
can switch current up to 30 Amperes. The ECW-GF is complete with
a 25-ft (7.6-m) temperature sensor and is housed in a NEMA 4X rated
enclosure. The controller features an AC/DC dry alarm contact relay
for monitoring critical applications such as fire protection piping.
The controller may be wall mounted or pipe mounted with the
optional FTC-PSK kit.
An optional ground-fault display panel (ECW-GF-DP) can be added
to provide ground-fault or alarm indication in applications where
the controller is mounted in inaccessible locations.
For technical support call Pentair Thermal Management at

• 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 scoring the jacket or core.
• Keep components and heating cable ends dry before and during
installation.
• Use only fire resistant insulation materials, such as fiberglass
wrap or flame-retardant foam.
• Needle nose pliers
• Wire strippers
