OPERATION
For metal sheathed heaters, prior to operation
an insulation resistance check must be
performed. Heater with values less than .5 MΩ
Ω Ω Ω Ω
should follow a drying process. Please contact
factory for details on procedure if heater is
under .5 MΩ
Ω Ω Ω Ω.
FIRE HAZARD. Heater element should be
submersed in the fluid for proper operation and
to avoid element overheating that could result in
fire or damage of the heater.
14.0 DISCONNECT POWER BEFORE SERVICING.
15.0 Perform an IR test prior to energization and verify that levels
are acceptable 500,000 ohms.
16.0 The TX heater has a general purpose terminal enclosure
which is not suitable for wet or hazardous locations or spray
washing.
17.0 Periodically check electrical connections for tightness.
18.0 Check that there is no water leakage at the heater to vessel
seal.
19.0 Check the immersion heater periodically to inspect for
corrosion or for sludge or scale build-up which must be removed
before re-energizing.
20.0 Always maintain a minimum of 25 mm (1”) of liquid above the
heated portion of the element or element failure may result.
MAINTENANCE
Disconnect all power before installing or
servicing the heater. Failure to do so could
result in personal injury and/or property damage.
All maintenance and installation should be done
by qualified personnel in compliance with local
codes.
21.0 Heaters stored for prolonged periods may absorb moisture.
Using a 500VDC 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.
22.0 Periodically check electrical connections for tightness and
check wire insulation for any damage and replace if necessary.
23.0 Remove the immersion heater periodically to inspect for
corrosion, sludge build-up and for scale removal. Do not continue to
use a heater showing visible signs of damage.

WIRING
10.0 Heaters must be wired by qualified personnel to local
electrical code requirements.
11.0 Check supply voltage and current for compliance with heater
nameplate voltage and wattage.
12.0 Suitable temperature controls and level controls are
recommended for a complete system.
13.0 The built-in cutout (when included) is a single pole device
rated at 25 amps. Whenever the heater current exceeds 25 amps or
when the heater is rated for three phase operation the cutout is
unwired and is intended for pilot duty only. This limit must then be field
wired to the coil of a suitably sized magnetic contactor provided by
others.
