DREXAN CMH-LE-1R Installation Instructions

WARNING: This is an electrical device and in order to ensure proper operation and prevent shock or fire it must
be installed correctly. Read these important warnings. Follow all installation instructions.
CAUTION: Ground-fault equipment protection shall be provided to de-energize all normally ungrounded conductors of
electrical heating cable sets, with ground fault settings sufficient to allow normal operation of the heater unless
applicable codes permit otherwise, and to minimize the danger of fire from sustained electrical arcing if the heating
cable is damaged or improperly installed and to comply with Drexan requirements, agency certifications and national
electrical codes. Conventional circuit breakers may not stop arcing.
Do not use substitute parts or use electrical tape unless directed. Component approvals and performance
characteristics are based on Drexan specific parts only. Substitution will void warrantee, approvals and performance
claims.
The heating cable core is conductive and can short if not properly insulated and kept dry. Component and heating
cable ends must be kept dry before and during installation. Fire-resistant thermal insulation materials should be used.
Heating cable core bus wires can overheat and short when damaged. When cutting the cable jacket or core do not
break bus wire strands.
 The metal sheath of CMH cable shall be grounded, but shall not be used as the grounding means.
 Metallic structures or materials such as metal pipes used to support CMH cable shall be grounded.
 CMH cable is not to cross or come in contact with itself.
 CMH cables are to be thermostatically controlled.
 CMH cable may be terminated or spliced in any certified enclosure mounted off heated surface.
