CHECKING INSTALLATION CONDITIONS

ATTACHING THE CABLE TO THE PIPE
1.
Before installing the heating cable, make sure that the area on and around the
pipe is free and clear of sharp edges and combustible materials. Remove old
heat tape before proceeding, and use the file to remove any sharp edges.
2.
Make sure there is a properly grounded electrical receptacle close enough to
plug in the cable. We strongly recommend the use of a GFCI protected circuit.
Use cable with a 120 V power cord and be sure the electrical outlet is not
overloaded. This heating cable will consume five amps or less. If an extension
cord is necessary, use only a properly sized and grounded product suitable for
outdoor use.
3. The minimum installation temperature of the cable is -10°C (14°F).
Never
install the SCPT heating cable when it is colder than this temperature. If the
heating cable is stiff (due to cold), first uncoil it and then plug it into a 120 V
power outlet until it is warm and pliable before unplugging it and applying it to
the pipe.
1.
The temperature sensor (located at the junction between the cold lead and
heating cable) must be placed tightly against the pipe and secured with fibreglass
or aluminum adhesive foil tape. The temperature sensor should be placed on
the coldest end of the pipe and turn the cable on and off to ensure economical
operation.
2.
Apply fibreglass or aluminum adhesive foil tape at 6 in. (15 cm) intervals to secure
the heating cable straight along the pipe. The minimum heating cable bend radius
is 1 in. (2.5 cm).
WARNING: Always use
fibreglass or aluminum
adhesive foil tape. Other
adhesive tapes may allow
the cable to move at
normal cable operating
temperatures and could
result in overheating, fire
or electrical shock.
