INSTRUCTIONS
INSTRUCTIONS
NOTE: DO NOT apply power to heater prior to
proper installation. Disconnect power supply to
heater before removing the heater.
1. Attach the heater assembly to the drum by hooking
the spring over the hook clip at the other heater end
as pictured below.
2. Most importantly, make sure that the heater is
perfectly flat against the side of the drum to avoid
hot spots that can shorten the life of the heater
(avoid installing heater over drum ridges).
a. DO NOT place the drum heater over dents or
extreme rust spots.
b. DO NOT immerse heater in water.
c. DO NOT operate heater at a voltage higher than
specified or rated as indicated on the label.
d. DO NOT expose heater to chemicals, acids,
alkalis, oils, fluids or other substances that could
ignite or cause damage to the heater.
e. DO NOT place any insulated material over the
heater unless adequate measures are taken to
control heater temperature.
f. DO NOT leave heater operating unattended
unless an external temperature controller is
installed to ensure safety.
g. DO NOT attempt to repair damaged heater.
Immediately discard damaged or torn heater to
avoid injury and hazardous conditions.
3. Heater must be below the level of liquid in the drum.
4. To avoid damaging the internal element of the
heater, do not bend the heater sharply.
5. It is recommended to open the bung to allow for
expansion of the contents when heating.
6. Make sure heater is installed and used by qualified,
trained professionals.
THERMOSTAT EQUIPMENT MODELS
1. Set the thermostat to the minimum temperature
setting by rotating the knob fully counter clockwise.
2. Follow the steps below to bring the temperature of
contents to desired level.
a. Rotate the thermostat clockwise a small amount.
b. Allow contents to stabilize at new temperature.
c. Repeat steps 1 and 2 until desired temperature is
reached.
IMPORTANT! The maximum allowable
temperature of the silicone rubber drum heater
is 450° F.
Certain conditions, such as thermodynamic
heat transfer involving the thermostat, physical
condition of the drum, liquid level in the drum
and the desired temperature of drum contents,
may cause the heater to exceed its maximum
temperature. Be careful to avoid damaging
the heater under such conditions.
