DESCRIPTION
1.0 Pipe insert heaters are designed for heating the air in a metal
pipe or tube which is, in turn, immersed in a liquid or attached to the
sides or ends of a sluice gate.
2.0 Use the heater only in approved applications. Check factory
for recommendations if you are unsure of the suitability of the MX
heater to your application.
INSTALLATION
DO NOT insulate over the heater flange, stilted
area and terminal enclosure.
Heaters with overtemperature devices require
specific installation orientation.
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.
INSTALLATION AND OPERATION INSTRUCTIONS FOR
PIPE INSERT HEATERS – TYPE MX
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.
3.0 Note that single phase heaters can be wired in groups for
three phase operation.
4.0 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).
5.0 Check supply voltage for compliance with heater nameplate
voltage. DO NOT connect the heater to a voltage source other than
listed on the heater nameplate.
6.0 Depending on heater length, they may be coiled to facilitate
shipping and handling. Gradual bends will not affect heater
performance; sharp bends could cause splitting of the heater sheath
and should be done only at the factory.
7.0 When energized, the heating element will expand in length.
Allow a minimum tolerance of 2% of the heater insert length inside the
pipe for expansion and factory tolerance.
8.0 The heater is suitable for horizontal (tank) or vertical (gate)
installation. In either orientation, the heater sheath is permitted to
touch the pipe wall since a hot spot will not occur due to the low watt
density on the heater sheath.
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.
FIRE/EXPLOSION HAZARD. Do not exceed the ratings of the flange as listed in ANSI B16.5. Do not operate
the heater in the presence of combustible gases, vapours, dusts or fibres unless the heater is specifically
marked for the hazardous location and heater operating temperature does not exceed the temperature code
rating. Corrosion of the sheath could result in a ground fault which, depending upon the fluid being heated,
could cause a fire or an explosion.
FIRE HAZARD. If a thermostat is provided, it is designed for temperature control service only. Since the
thermostat does not fail safe, it should not be used for temperature limiting duty. Wiring to this device is the
users responsibility.
Heaters are capable of developing high temperatures, therefore extreme care should be taken to:
a) use explosion-proof terminal enclosures in hazardous locations;
b) maintain distance between heater and combustible materials.
