INSTALLING THE THERMOSTAT
1. Verify that the thermostat is
suitable for the area where it is to
be installed.
2. Check the line voltage and the
heat-tracing load to ensure that
the thermostat ratings are not exceeded.
3. Mount the unit using unistrut or the Raychem universal
mounting bracket (UMB-263757) in a position that prevents
condensation from draining into the enclosure from the
connecting conduit (see diagram above).
POSITIONING THE SENSOR BULB
4. Position the bulb in the
lower quadrant of the pipe
as shown in the diagrams
to the left. Place the bulb
at least three feet from
pipe supports, valves, or
other heat sinks; protect
the capillary from kinks or
bends less than 1⁄2 inch in
radius.

5. Tape the bulb firmly to the pipe with AT-180 aluminum tape,
making sure there is no air space between the bulb and pipe.
Do not overlap the bulb and heating cable with the same piece
of AT-180 tape.
6. For metal-tank-wall sensing, use the BCK-35 bulb clamp
(purchased separately from Raychem) and install the clamp
per the instructions provided. Make sure there is no air space
between the tank wall and the bulb.
For installation on plastic tanks, contact Pentair Thermal
Management at (800) 545-6258.
SETTING THE THERMOSTAT
7. Set the thermostat dial to the desired temperature, then finish
wiring.
8. Complete insulating. Do not turn the system on until the bulb is
covered with thermal insulation.
9. Fill the piping or tank. Once the thermostat has begun to cycle,
check the fluid temperature with an immersed thermostat
(best for plastic systems) or an accurate temperature indicator.
Adjust the dial setting, if necessary.
