2. For proper temperature control, secure the thermocouple, RTD, or other sensing device, vertically along the lead wire
seam of the blanket with one strip of adhesive tape so that it is sandwiched firmly in-between the heater and glass
beaker.
- Sensor must be in close proximity to the heater to prevent overheating.
- Sensor should be connected in accordance with instructions provided with temperature controller.
3. Ensure heater is in contact with the surface to be heated. The heater must be tightly wrapped around the glass
beaker. Minimal air gaps between the heater and the beaker provide the best heat transfer and best heater life.
Do not wrap the heated areas of the blanket over itself or allow it to contact a second heater.
4. Once the beaker heater has been properly setup:
120VAC: Plug the heater into an acceptable temperature
controller. Use a variable transformer, manual control, or
automatic controller to prevent overheating.
240VAC: The two wires (same color) must be connected to
the temperature control device directly or to a connector that is
mated to a receptacle connected to the temperature control source. These heaters are non-polarized, allowing either
wire to be connected to neutral or hot.
All electrical connections must be made by qualified personnel and in accordance with all applicable
codes and regulations.
To Avoid Damage:
x
Never plug directly into a power source. Your heater MUST be operated with a temperature controller and with an
appropriate sized beaker, filled with fluid.
x
Never operate heater without fluid within the flask.
x
Never operate the heater at temperatures above 232qC (450qF).

PROBLEM
Does not heat
Circuit breaker is
tripping
Does not fit
SOLUTION(S)
Verify heater is connected to proper voltage.
reading (not an open circuit) in heater using an ohm meter.
Validate that the circuit breaker is capable of handling the amp requirement of heater. The
identification 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.
Designed for only specific sized glass beakers. Check to be sure the beaker size and
heater size match.
