SAFETY PRECAUTIONS

YOUR SAFETY AND THE SAFETY OF OTHERS IS EXTREMELY IMPORTANT.
We have provided important safety messages in this manual for your product. Always read and obey all safety messages. Safety alert symbols alert you to hazards that can kill or harm you as well as others. The safety alert symbol and the words “DANGER” and “WARNING” will precede all safety messages. Read the following words and what they signify:

• DANGER: You may be killed or seriously injured if you don’t follow these instructions.
• WARNING: You may be seriously injured if you don’t follow these instructions.

All safety messages will identify the hazard, tell you how to reduce the chance of injury and tell you what can happen if the safety instructions are not followed.
NOTE: Certain atmospheres within the tank being cleaned could become explosive, such as dust particles in a flour silo, or fumes in paint mixing tanks. For this reason, the following safety precautions should be observed.

INSTALLATION PRECAUTIONS

Qualified personnel must perform all work required to assemble, install, operate, maintain and repair this equipment. Improper installation and operation can result in severe personal injury and/or damage to property. Correct installation is your responsibility.

WARNING : Install proper guards as needed. Follow basic lifting guides when transporting or handling this product. Failure to follow this instruction can result in back injury, burns or other serious injury.
CONNECTIONS
Please refer to datasheet 290E-EP during installation. Also reference the instructions for the electric motor shipped with the 290E-EP tank washer. Connect the power supply to the conduit connection hole as shown on datasheet 290E-EP, and verify that the nozzle hub rotates clockwise when viewed from the nozzle hub end. Connect the liquid line to the inlet connection of the liquid inlet body.

WIRING
Route cabling through the most appropriate conduit entry making sure that cables will not foul on the cover assembly or internal components after refitting. Refer to the motor wiring diagram for connection details. Wire type must meet local and certifying agency (CSA, IEC Ex, ATEX, etc.) requirements and have a minimum temperature rating of 88°C.
MOUNTING
Bolt or clamp the unit to the tank to be cleaned as dictated by the mounting flange provided. Adjustable flanges allow easy positioning of the tank wash unit to various spray depths for maximum cleaning effectiveness.
LIQUID INLET CONNECTION
Proper installation requires liquid supply line (pipe, hose, etc.) meet or exceed maximum working pressure. Use of PTFE Pipe Tape or other appropriate sealant compatible with your process fluids is highly recommended for leak free connections.

DANGER: Failure to install the tank washer with insufficient connections could result in leaks and/or explosion. If you do not follow these instructions, you may be killed or seriously injured.

MECHANICAL CLEARANCES

Proper installation requires that sufficient clearance be maintained between the rotary housing and nozzles of the tank wash unit and any internal baffles or the walls of the tank being cleaned.

• DANGER : It is your responsibility to ensure that there is no possibility of the moving parts coming in contact with fixed objects. Failure to install the tank washer with sufficient clearances could result in the generation of sparks with a resultant explosion or fire. If you do not follow these instructions, you may be killed or seriously injured.

GENERAL SAFETY

1. Never allow motor to be submerged in any liquid or operated while wet.
2. Never touch unit with wet hands or while standing in a wet environment until power is turned off to unit.
3. Always use a properly grounded power supply to unit.
4. Use wire/extension cords should be underwriters laboratories listed. The proper fuse size should always be used.
5. All wiring should be performed by a qualified electrician and follow all electrical and safety codes as well as the most recent national electrical code (NEC) and the occupational safety and health act (OSHA).
6. Protect electrical cord from sharp objects, hot surfaces, oil, and chemicals. Avoid kinking the cord. Replace or repair damaged or worn cords immediately.
7. Disconnect power before servicing unit. If power disconnect is out of sights, lock it in the open position and tag it to prevent unexpected application of power.
8. Do not touch an operating motor. Modern motors are designed to operate at high temperatures.
9. Never operate unit around explosive fumes or liquids or in an explosive atmosphere.

GROUNDING
A ground screw is provided on the Liquid Inlet Body marked with a ground symbol. A ground wire should be clamped under the screw head and connected to earth ground via an approved grounding method. Likewise, a ground wire should be affixed to the tank and terminated at an earth ground.

• DANGER: It is not sufficient to ground only the tank washer or the tank itself because the electrical continuity between the tank wash unit and tank cannot be guaranteed. A separate ground connection from both the tank wash unit and the tank itself should be made. Failure to follow this instruction can result in buildup of static charge between the tank and the tank washer parts which could cause a sudden discharge of current with a resultant explosion or fire. You may be killed or seriously injured if you do not follow these instructions.

HIGH IMPACT SPRAYS
This tank washer may be equipped with solid stream nozzles which concentrate the flow energy into a small area for maximum impact and cleaning efficiency. Operation at high pressure increases their effectiveness but also creates a hazard if the proper precautions are not followed.

• WARNING: INJURY HAZARD FROM HIGH IMPACT SPRAYS. High impact sprays can cause severe injury. The liquid pressure to the tank washer should never be turned on while the unit is outside the tank. Failure to follow this instruction can result in fluid penetration through clothing and into the human skin causing severe injury, possibly resulting in amputation or death. If any part of the body comes in contact with the spray stream, immediately consult a physician.

OPERATION PRECAUTIONS

It is your responsibly to operate this product at recommended speeds, loads and temperatures.
Run the unit within the specified pressures and flow rates for the liquid and air motor to ensure safety. To maintain proper operations do not run the unit dry, always keep liquid flow on before stopping the air motor.

• DANGER : DO NOT USE TO SPRAY FLAMMABLE LIQUIDS–SUCH USE COULD RESULT IN FIRE OR EXPLOSION CAUSING BODILY INJURY OR DEATH. Sound level from motor may exceed 85db(A). Check compatibility of service fluid with materials used to construct this product. Use a pressure gauge to monitor liquid pressure (see 290E-EP-1 for flow rate data). Ensure that the pumping system has monitor controls and emergency shut off system in case of pressure spike which can cause harm to this product. Failure to follow this instruction can result in burns, eye injury or other serious injury.
