INSTALLATION
DO NOT insulate over the heater flange, or
terminal enclosure.
ELECTRIC SHOCK HAZARD. 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.
FIRE OR SHOCK HAZARD: Moisture
accumulation on the dielectric material of the
elements, sheath corrosion or overtemperature
on the heaters could cause a fault to ground
generating arcing and molten metal. Install
proper ground fault protections to prevent
personal injury or property damage.
Heaters are electrical components only, and
system designers are responsible for the proper
integration to the electrical systems, including
safety protections, back-ups and controls.
1.0 Unpack and check heater for any damage that may have
been caused during shipping.
Use copper conductors only with sufficient
current carrying capacity for the heater circuit
load and in accordance with the local electrical
code. Check the heater nameplate for minimum
conductor temperature rating. Temperature
deration factors must be applied for heaters
operating above 30°C(86°F).
2.0 TX heaters are designed primarily for heating water at
atmospheric pressure in steam tables, coffee urns, kettles, etc.
During operation the heating elements must be fully immersed.
Operation of heaters with elements exposed to air may present a fire
hazard and will also result in premature failure of the heater.

TYPES TXC, TXCC, TXI, & TXIC IMMERSION HEATERS
ELECTRIC SHOCK HAZARD. All electric heating equipment installations must be performed
by qualified personnel in accordance with the local electrical codes and standards and
must be effectively grounded to eliminate shock hazard.
Heaters are capable of developing high temperatures, therefore extreme care should be
taken to maintain distance between heater and combustible materials.
FOR USE ONLY SUBMERSED IN WATER
3.0 The TX heater is available with copper or incoloy sheathed
elements (see Table 1). Incoloy sheathed models are intended for
severe water conditions.

TXI Incoloy Sheath (no cutout)
TXIC Incoloy Sheath with cutout
4.0 If there is any possibility that the liquid level could fall,
exposing the elements, a model with a built-in low level cutout is
required (see Table 1). Note that the cutout is a safety device to
guard against abnormal conditions and should not be used as a
regular control means.
5.0 The heater is normally installed in the bottom of the vessel or
tank. In special circumstances the heater can be adapted for side
mounting (check factory).
6.0 A 2 7 /
16
" (62 mm) diameter hole is required for mounting.
7.0 Since the heater is installed from the inside of the tank,
a handhole opening in the tank top or side may be required (see
Table 2).

8.0 Refer to Figure 1 for installation details. Note that the heater
utilizes an "O" Ring to provide a liquid tight seal. Ensure that the
contact surfaces are clean.
9.0 Three mounting screws are used to compress the "O" Ring.
Tighten screws a bit-at-a-time to effect even seating of the gasket.
