WARNING: To ensure the drive is not unexpectedly
started, turn off and lock-out or tag power source before
proceeding. Failure to observe these precautions could
result in bodily injury.
WARNING: All products over 25 kg (55 lbs) are noted on the
shipping package. Proper lifting practices are required for
these products.
The Dodge heater and thermostat is combined into one
assembly. The thermostat is built into the first 2" from the tip of
the heater. The thermostat is set to turn the heater on at 70°F
(21°C) and off at 100°F (38°C). Also, an LED indicates when the
heater is on.
Assembly components:
1. Heater-Thermostat
2. LED light
3. Toroid (copper winding ring)
4. LB conduit enclosure
5. Brass Reducer*
6. Aluminum reducer (for electrical outlet)
*Only used when the heater plug on the bearing is 1/2" or 3/4"
NPT.
WARNING: Because of the possible danger to person(s) or
property from accidents which may result from the improper
use of products, it is important that correct procedures be
followed. Products must be used in accordance with the
engineering information specified in the catalog. Proper
installation, maintenance and operation procedures must
be observed. The instructions in the instruction manuals
must be followed. Inspections should be made as necessary
to assure safe operation under prevailing conditions. Proper
guards and other suitable safety devices or procedures as
may be desirable or as may be specified in safety codes
should be provided, and are neither provided by ABB nor
are the responsibility of ABB. This unit and its associated
equipment must be installed, adjusted and maintained by
qualified personnel who are familiar with the construction
and operation of all equipment in the system and the
potential hazards involved. When risk to persons or property
may be involved, a holding device must be an integral part
of the driven equipment beyond the speed reducer output
shaft.

1. Shut down the main fan by following the manufacturer's
instructions.
2. To prevent oil from seeping out during installation, drain
the oil from the bearing until the oil level is below the
heater plug. The heater plug location is specified in the
appropriate Sleevoil Instruction Manual.
NOTE: If the heater-thermostat is replacing an existing
heater and thermostat, the old thermostat should be
removed and replaced with a threaded plug.
3. Remove the heater plug.
4. Apply sealant to the pipe fitting (inner threads) on the
heater-thermostat and install it in the bearing housing
where the heater plug was removed. (On bearings where
the heater plug is 1/2" or 3/4" NPT, use sealant to install the
supplied brass reducer first.)
5. The conduit body can be mounted vertically or horizontally.
Determine which mounting configuration will be easiest to
install. If space limitations prevent the LB enclosure from
being installed, alternate conduit can be provided by a
qualified electrician. Use sealant to install the conduit body
on the outer threads of the heater thermostat.
6. Wrap one of the two red power leads around the toroid
(copper winding ring) 1 or 2 times. See Figure 1.
7. Connect the heater leads to a power supply and
ground. The 2 red leads are 120 or 240 VAC power leads
(depending on heater) and the green lead with the yellow
tracer is the ground lead.
8. The aluminum reducer is for the outlet of the conduit
enclosure and can be installed if desired.
9. Install the conduit body cover.
10. Fill the bearing with oil to its recommended level.

WARNING: Do not start the fan if the oil temperature is too
low. This can result in an insufficient oil film in the bearing
which may result in bearing failure. ABB recommends the
oil temperature to be 70°F (21°C) or above.
