all must be de-energized prior to performing any maintenance on a control
circuit.
Warning: The HTC-915 control module must be protected by external over
current and disconnect devices.

MAINTENANCE
Operator Maintenance
The HTC-915 control system is designed to be a maintenance free product.
Replaceable Parts
There are no user-serviceable parts in the HTC-915 series controller or
accessories. The unit is designed to be easily changed out in the field in a matter
of minutes.
Any HTC-915 system component appearing inoperative should be returned to
the nearest Pentair Thermal Management office.
Cleaning
If the HTC-915 components require cleaning, a damp cloth may be used to
wipe the units. This should only be done while the units are disconnected from
their power source. Do not use any harsh chemicals or solvents, as this may
damage the housing or finish.
ELECTRICAL CONNECTION
Connections are made via screw connections suitable to accept cable diameters
between 0.5 and 2.5 mm (24 to 12 Awg). Either solid or stranded wires may be
2
used.
Do not rely on the controller as a disconnect device!
Installation notes
• If contact with live parts is possible while working on the unit, it must be
completely isolated from the mains supply. Be aware that the unit might have
cables connected to it which are powered from different sources.
• Magnetic or electric fields, eg: from transformers, mobile phones or
electrostatic discharge must be avoided in the vicinity of the instrument.
• Route input, output and supply lines separately.
• Arrange sensor cable extensions as twisted and screened cables. Do not
run them close to power cables. The shield, if any, shall be earthed on the
controller's side only.
• Fluctuations in the supply signals are only permissible within the specified
tolerances.
