MOUNTING YOUR HEATING BLANKET
1. If your heating blanket does not have its own internal temperature control
device, it
must
be connected to an external control device. The heater must not
be operated without some form of temperature control.
- Your heater is designed to operate at a speci fi c voltage ±10%. Refer to the label on the heater
for proper operating voltage and wattage information. Failure to operate the heater at the speci fi ed
rating could result in overheating of the heating blanket, the surface being heated, or personal injury.
Also note lower-than-rated voltage will result in under-heating.
- All electrical connections must be made by quali fi ed personnel and in accordance with all applicable
codes and regulations.
- SEBHB series: A NRTL (National Recognized Testing Laboratory) listed temperature controller with
a failure annunciation must be used to control the surface temperature of the blanket. The controller
must be approved for the area where it is located.
Installation of heater using factory supplied Pressure Sensitive Adhesive
(PSA):
3. Peel off the release fi lm [Figure A] and then press the heater onto the surface
of the item being heated using a medium to hard rubber roller [Figure B]. Ensure
blanket is making intimate contact with the surface to be heated.
- The pressure sensitive adhesive will cure when the blanket is energized
and heat is generated. PSA generally cures in twenty minutes at 200ºF
(93ºC) in a 68ºF (20ºC) ambient environment. The cure time will vary
with temperature of the blanket and surrounding ambient conditions.
The higher the ambient temperature and set-point of the blanket, the
faster the cure time.
- The blanket may require a temporary method of attachment to secure
the heater until the PSA cures. Use a high-temperature adhesive tape
to secure the heater.
- For larger heaters, press the heater onto the surface as the fi lm is
removed.
NOTE: OMEGA
®
does not recommend allowing pressure sensitive adhesive to
cure at temperatures below 40ºF (4ºC).

TROUBLESHOOTING GUIDE
PROBLEM SOLUTION(S)
Does not heat Verify heater is connected to proper voltage.
Check to see if there is a resistance reading (not an
open circuit) in heater using an ohm meter.
Pressure sensitive adhesive is not
adhering Verify date of manufacture. PSA has a shelf life of six
months.
Ensure there are no air gaps and heater is making
intimate contact with surface being heated. Use a
medium to hard rubber roller.
Circuit breaker is tripping Validate that the circuit breaker is capable of handling
the amp requirement of heater. The identi
fi cation
label located on the power cord displays the heater’s
amperage requirement.
Examine heater and cord for any damage.
Check to see if there is a resistance reading between
power leads and the ground lead.
2. Most heating blankets are available with an optional high-limit safety
thermostat to protect both the heater and the product being heated from
damage if the main controlling device fails. This option is especially
recommended for surfaces that are high risk for heat damage (e.g. plastic).
3. Ensure heater is protected by a properly rated circuit breaker or fuse.
4. Use of a ground fault circuit interrupter (GFCI) is highly recommended and
may be required according to local electric code.
5. Two wires (same color) should be connected to the power source (or
temperature control device) directly, through a junction box, or to a connector that
is mated to a receptacle connected to the power source. These heating blankets
are non-polarized, allowing either wire to be connected to the neutral or hot. The
third wire (if applicable), designated by the color green (or a green stripe), should
be connected to ground.
6. SEBHB series: The conduit connection is 3/4” hub.
