INSTRUCTIONS

INSTALLATION

WARNING! Electrical terminations must be completed by qualified person.

NOTE: Installation temperature range is -60°F to 131°F.

NOTE: Minimum clearance of 3" is required around vessel during installation.

NOTE: Voltage and frequency must be within +/- 10% of the rated value specified on the product.

SURFACE PREPARATION

Always install heater on a clean, even surface for best performance and longevity. Debris and residue on the surface can not only damage heater, but may also reduce the effectiveness of the heater by reducing the heat transfer between the surface and the heater.

NOTE: Remove or avoid contact with sharp edges including rough corners, welds and weld spatter, exposed bolts, dents, etc.

NOTE: Remove or avoid contact with rust, stickers or other coverings.

NOTE: Remove oil, moisture, gel or other liquids from the vessel's surface.

1. Inspect heater prior to each installation.
2. Inspect vessel to be heated for any sharp edges, rust, oil, etc.
3. Ensure there are no combustible materials within 12" of the surface to be heated.
4. Select a suitable location to install the heater.
5. Attach the heater assembly to the drum to be heated by hooking the spring over the hook clip at the other heater end. (See Figure 1)

Finger Grip Figure 1 Hook End Place loop of spring over hook when installing.

1. Wrap the heater tightly around the drum where it will be in full contact with the drum, ensuring the heater is perfectly flat and straight against the side of the drum to avoid hot spots that can shorten the life of the heater (avoid installing heater over drum ridges).

NOTE: Do not place drum heater over dents or extreme rust spots.

NOTE: Do not immerse heater in liquid.

NOTE: Do not operate heater at a voltage higher than the specified or rated voltage as indicated on the label.

NOTE: Do not expose heater to chemicals, acids, alkalis, oils, fluids or other substances that could ignite or cause damage to the heater.

NOTE: Do not place any insulated material over the heater unless adequate measures are taken to control heater temperature.

NOTE: Do not leave heaters operating unattended unless an external high limit temperature controller is installed to ensure safety.

NOTE: Do not attempt to repair damaged heater. Immediately discard damaged or torn heater to avoid injury and hazardous conditions.

1. The heater must be mounted below the level of liquid in the drum. The heater should be located below the lowest expected content level (typically the bottom 1/3) of the vessel.
2. To avoid damaging the internal element of the heater, do not bend the heater sharply.
3. Do not twist the heater or cover any protrusions that may cause an air gap between the vessel and the heater.
4. It is recommended to open the bung of the vessel to allow for expansion of the contents when heating.
5. Ensure heater is installed and used by qualified, trained professionals.

NOTE: When not in use, heater should be rolled for convenient storage and placed in original packaging.

CONNECTING HEATER TO POWER SOURCE

WARNING! All electrical wiring must be completed by qualified person and must be in compliance with local codes and regulations.

HEATER PROVIDED WITH A PLUG

Connect the provided plug to the matching power supply receptacle.

INSTRUCTIONS CONTINUED

HEATER PROVIDED WITH WIRE LEADS

The power cable consists of three color-coded conductors: black, white and green. The black wire should be connected to line 1. The white wire should be connected to line 2. The green wire should be connected to earth ground. The power connections must be adequately rated to electrically support the voltage and amperage of the heater. The identification mark on the heater displays voltage and wattage of the heater. Never cut or remove the ground plug pin.

THERMOSTAT-EQUIPPED MODELS

1. Before connecting the heater to an electrical source, set the thermostat to the minimum temperature setting by rotating the knob fully counterclockwise.
2. Follow the steps below to bring the temperature of contents to desired level.

a. Rotate thermostat clockwise a small amount.
b. Allow contents to stabilize at new temperature. Stabilization may take a few hours. Ensure temperature has stabilized before increasing the temperature set point.
c. Repeat steps 1 and 2 until desired temperature is reached.

1. The maximum allowable temperature of the silicone rubber drum heater is 450^ F.

NOTE: 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 thermostat to allow the set temperature to be exceeded.

NOTE: Be careful to avoid damaging the heater prematurely.

NOTE: Ambient conditions will affect the dial's position in which the heater begins to heat. In cooler temperature conditions, the heater will begin to heat at a lower temperature position on the dial. In warmer temperature conditions, the heater will begin to heat at a higher temperature position on the dial. It is recommended that a thermometer is attached to the vessel being heated. Adjust the dial until you achieve the desired temperature.

NOTE: For heating temperature-sensitive materials that require a specific set-point or have a tight tolerance temperature range, use of an external temperature controlling device is required. Select a temperature controller that has the accuracy necessary for the application and is approved for the location and conditions where the heater is to be used. If assistance determining a proper temperature controlling device is required, contact Uline Customer Service at 1-800-295-5510.

EMERGENCY PROCEDURES

Read and understand these procedures prior to using the heater. Disconnect power to the heater in the event of an emergency.

ELECTRIC SHOCK

• Do not touch the injured person while they are still in contact with the electrical current.
• Call emergency service if injured person experiences severe burns, confusion, difficulty breathing, heart rhythm problems, cardiac arrest, muscle pain and contractions, seizures or a loss of consciousness.

MINOR BURNS

• Hold the burned area under cool running water for 10-15 minutes.
• Remove rings or other tight-fitting items from the burned areas.

MAJOR BURNS

• Call local emergency service.
• Protect the person from further harm.
• Remove rings or other tight-fitting items from the burned areas.
  • Monitor breathing and perform CPR if necessary.

FIRE

• Call local emergency service.
• If it is safe to do so, use a fire extinguisher to fight the fire; otherwise, evacuate to a safe distance and wait for help to arrive.
• This heater is built from materials that will not support a flame but could ignite nearby combustible materials.

MAINTENANCE AND INSPECTION

• All maintenance and inspection should be performed after heater has cooled to room temperature and with the electricity disconnected.
• This product should be inspected prior to being installed and at least every three months during use.
• Dirt, oil, grease or other foreign matter can be removed with a damp rag and mild household cleaners.
• Do not attempt to repair a damaged heater.

• The heater should be free of any cuts, cracks or punctures.

• The power leads should not have any visible breaks in their insulation.

• The heater should be free of any buildup of dirt, oil, grease or other foreign matter.
• Store product indoors. After cooling, it is recommended that the heater be rolled up and placed in its original box. Never fold or crease the heater.
• This product does not contain any hazardous materials and may be discarded with domestic waste.

TROUBLESHOOTING

OPERATING ISSUE RECOMMENDATIONS

Does not heat. Verify heater is connected to proper voltage. The identification stamp located on the heater displays the heater's voltage requirements.If supplied with a thermostat, set the dial to the maximum heating position. Using an ohm meter, check to see if there is a resistance reading (not an open circuit) in the heater. Correct OHMS is approximately R = V^2/W .If external temperature controlling device is installed, ensure the heater's control dial is in the maximum heating position.

Circuit breaker is tripping. Validate that the circuit breaker is capable of handling the amp requirement of the heater: A = W/V.Examine heater and cord for any damage.

Does not fit. Confirm that the heater provided was designed to fit around specified drum. The heater is intended to fit tightly on the drum when the spring is connected to the hook end.
