Install Instructions

If it is not possible to locate the power control enclosure within 10 ft of the
estimated coldest point of the water pipe, the thermostat adjustment capability
can compensate for this. In such a case, however, the thermostat sensor must
be installed onto a section of the piping, which is expected to be reasonably
cold. In a typical installation of a home/cottage located on a lake with a rocky
shoreline, the piping on the outside of the cottage/home foundation could usually
be expected to be reasonably cold, even though not as cold, perhaps, as the
piping at the rocky lakeshore. Attaching the thermostat sensor to the piping
immediately outside the building foundation and increasing the thermostat
setpoint will still enable the thermostat control to keep the coldest section of
piping from freezing while minimizing energy consumption. Refer also to the
section “Operation of the Heating Cable”.
It is recommended that the power control enclosure and the T-coupling be
mounted in a dry area where no damage will occur to the water line heating
system connections. The T-coupling should be located as close as possible to
the pump, but more importantly, in close proximity to the location of the power
control enclosure. It is suggested that the pumping system be located in a
heated area, as the pump and associated downstream piping must also be
protected from freezing.
Another factor in establishing the location for the power control enclosure should
be the requirement to regularly test the GFCI. Also, the possibility of the heating
cable becoming inadvertently unplugged should be considered. The power
control enclosure contains a GFCI, and hence it is not necessary for this control
to be connected to a GFCI protected outlet. However, it is possible to plug the
power control enclosure into a GFCI protected receptacle, if convenient.
It is recommended that the heating cable be the only load on the circuit supplying
electrical power to the cable.
