4.1 general notes
Use the Design Specification to select required components. Pentair
Thermal Management components must be used to satisfy Standards
and Approval Body requirements and the Pentair Thermal Management
warranty to apply.
4.2 Component installation hints
On horizontal pipes locate junction boxes below pipe where ever
possible.
Locate junction boxes for easy access, but not exposed to
mechanical abuse.
Try to position junction boxes such, that power cable and heating
cable entries point downwards to avoid water ingress in the
insulation.
Confirm junction box glands and stopping plugs are
appropriate for application and fixed firmly in place.
Route heating cable between junction box and the place where it
enters the insulation cladding such, that the risk of mechanical
damage is minimized.
Do not strain heating cable as it exits/enters junction boxes and
insulation entries.
Ensure heating cable is fixed over pipe straps such as used for
junction box support brackets so as to avoid potential mechanical
damage:
Cable joints (splices) should be located only in places, where
cable is not bent or mechanically stressed.
