Bolt Heaters
IXS Series
Installation & Maintenance Instructions
1. Installation
1.1
Bolt heaters are designed for operation only while
completely inserted into the bolt holes.
1.2
The stainless steel ¾" BSPF threaded fitting at the
cold end is used to hold the heater in an upright
position if a corresponding thread is provided at the
bolt hole.
1.3
Protect terminals of heating elements from drippings,
condensation, fumes, spray or any other substance
which could result in element contamination.
1.4
Heaters must be wired by qualified personnel to
electrical code requirements.
1.5
Check supply voltage for compliance with heater
nameplate voltage before energizing.
1.6
Ensure the heater is cooled and power supply is
disconnected when removing the heater from the
bolt hole.
2. Start-up Inspection
2.1
Check that all terminal connections are tight.
2.2
Heaters stored for prolonged periods may absorb
moisture. Using a megger (insulation resistance tester)
check the value of the insulation resistance to ground
for each circuit. Initial readings of over 500,000 ohms
to ground are normally acceptable. Should lower
readings be observed, check factory for instructions.
3. Maintenance
3.1
DISCONNECT POWER BEFORE SERVICING.
3.2
Inspect periodically for corrosion, sludge build-up and
for scale removal.
3.3
Periodically check electrical connections for tightness.
