INSTRUCTIONS

WARNING! Do not leave on overnight or for extended periods of time. Most products do not require full power. Once heated to point of use, turn off and remove heater from drum.

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.
