INTRODUCTION
This tank washer meets the requirements set forth in EC
Directive 2006/42/EC. The latest motor manufacturer’s
Operation & Maintenance Manual is included with this
tank washer as a separate manual since important safety
precautions pertaining to the installation and operation
of the motor itself are included.

Spray Head with two nozzles
fits through a 7.25” (184.1 mm)
dia. opening
Spray Head with four nozzles
fits through a 8.25” (209.5 mm)
dia. opening
Tanks over the specified diameters could possibly be
cleaned adequately depending on the maximum tank
dimension, cleaning solutions being used, temperatures,
spray pressures, flow rates and the material being
cleaned from the tank.
The tank washer may be used with plain water or with a
variety of chemicals (compatible with 316 SS, ethylene
propylene rubber, and carbon graphite filled Teflon®).
However, if chemicals are used, review MSDS sheets and
chemical compatibility with material used to construct
this product. Also, the unit should be flushed with clean
water at the end of the day before the unit is stored. A
liquid line strainer ahead of the unit is recommended to
remove large particles which may damage the unit.

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.
