Introduction
This manual has been prepared as a guide for the persons who will be operating and maintaining your tank
cleaning machine.
The key to long life for your tank cleaning machine is a carefully planned system for preventive maintenance;
you must appreciate that a tank cleaning machine which has a rough and dirty job to do will need more
frequent attention than one working under ideal conditions.
Note: Get the best and most economical performance from your tank cleaning machine. Insufficient
preventive maintenance means poor performance, unscheduled stops, shorter lifetime and extra costs. Good
preventive maintenance on the contrary means good performance, no unscheduled stops and superior total
economy.
The information in this manual is simple to follow, but should you require further assistance, our Customer
Service Department and world-wide net of Distributors will be pleased to help you. Please quote the type,
article and serial number with all your enquiries; this will help us to help you. The type, article and serial
number are placed on the gear house of the tank cleaning machine.
Note: The illustrations and specifications contained in this manual were effective at the date of printing.
However, as continuous improvements are our policy, we reserve the right to alter or modify any unit
specification on any product without prior notice or any obligation.

General Description
The Toftejorg TZ-89 is a media driven and media lubricated tank cleaning machine. No lubricating
substances such as oil or grease are used. All materials are selected for contact with food.
Functioning
The flow of the cleaning fluid passes through a guide
and a turbine, which accordingly is set into rotation.
Through a gear set and a driver tube, the turbine
rotation is transmitted to the Cleaner Head.
The 90O Angle gear in the Cleaner Head transmits the
rotation from the gear unit to a horizontal rotation of
the Cleaner Head body and a vertical rotation of the
Nozzle head.
The combined motion of the Cleaner head and the
Nozzle head ensures a fully indexed tank cleaning
coverage. After 5 1/8 (for 2 nozzle version: 10 1/4)
revolutions of the Nozzle head, corresponding to 4 7/8
(for 2 nozzle version: 9 3/4) revolutions of the cleaner
head, a coarse cleaning pattern is laid out on the tank
surface and the first cycle has been made. During the
following cycles, this pattern is repeated 7 (for 2
nozzle version: 3) times, each of which is displaced
and the pattern gradually becomes more dense. After
8 (for 2 nozzle version: 4) cycles - a total of 41
revolutions of the Nozzle head (39 revolutions of the
Cleaner head), a complete cleaning pattern has been
laid out, and the first pattern is repeated.
A complete cleaning pattern is illustrated below for a
square tank with the machine placed in the centre:

Throw length
Note: Throw lengths are measured as horizontal
throw length at static condition. Vertical throw
length upwards is approx. 1/3 less.
Effective throw length is defined as impact centre
of jet 250 mm water column (50 lbs/sq.ft).
Effective throw length varies depending on jet
transverse speed over surface, substance to be
removed, cleaning procedure and agent.
The inlet pressure has been taken immediately
before the machine inlet. In order to achieve the
performance indicated in the curves, the pressure
drop in the supply lines between pump and
machine must be taken into consideration.

Installation and Normal Operation
General Installation Instructions
The Toftejorg TZ-89 is designed to be installed in a vertical upright position, however, the machine can
operate horizontally or in any desired angle position.
The machine is equipped with a sliding and locking type flange connection, permitting to adjust the
protruding of the cleaning head into the tank from 65 - 766 mm for the standard configuration. For the
optional lengths, the max. protuding varies with the length.
It is recommended to install a filter with mesh size 250 µm (0,01") in the supply line in order to avoid
particles, scale, etc. from clogging inside the machine. It is essential to avoid fine solid particles, such as fine
sand, in the cleaning fluid as they will increase wear considerably. This is particular important in case of
recirculation.
It is recommended that the fluid valve fitted is of a type that prevents hydraulic shocks, which may cause
severe damage to the entire installation.
Before installation, all supply lines and valves must be flushed to remove remains of welding electrodes,
grinding dust, scale and other foreign matter.
Note: Do not try to turn Nozzle head by hand, since this will damage the Gear. Nozzle head can be turned
by blowing air from an air pistol through the inlet connection.
Note: The machine shall be installed in accordance with national regulations for safety and other relevant
regulations and standards. Precautions shall be made to prevent starting of the cleaning operation, while
personnel are inside the tank or otherwise can be hit by jets from the nozzles. In EU-countries the complete
system must fulfil the EU-machine directive and shall be CE-marked.
Warning:
If the machine is used in potential explosive atmospheres, tapes or joint sealing compounds
which are electrical insulators must not be used on threads or joints. In addition, connecting
pipe work, must be electrically conductive and earthed to the tank structure.
This is essential to avoid the build-up of static electricity on the machine.

IM-TE91A500-EN4
Installation and Normal Operation (continued)
Normal Operation
Pressure
In order to protect the machine, your pipe and valve installation, etc. against damage:
Avoid hydraulic shocks! Put on pressure gradually!
Recommended working pressure: 3 - 6 bar (44 - 87 psi). Too high pressure will increase consumption of
wear parts.
Cleaning Media
Use only cleaning fluids, which are compatible with Stainless Steel AISI 316/316L, SAF2205, FEP/Silicone,
PEEK and PTFE. Please note that PEEK is not resistant to concentrated sulfuric acid. Normal detergents,
moderate solutions of acids and alkalics are acceptable as well as a number of solvents at ambient
temperature during cleaning. Aggressive chemicals, excessive concentrations of chemicals at elevated
temperatures as well as certain dissolvents and hydrochlorides should be avoided. If you are in doubt,
contact your local Alfa Laval Tank Equipment sales office.
After-Use Cleaning
Cleaning solutions must never be allowed to dry out in the machine, due to possible "salting out" or "scaling"
of the cleaning ingredient. Therefore, the machine should always be flushed with fresh water after it has
been used. The machine is self-draining.

IM-TE91A500-EN4
Preventive Maintenance
In order to keep your tank cleaning machine servicing you as an efficient tool in your tank cleaning
operations, it is essential to maintain its high performance by following a simple preventive maintenance
programme.
Good maintenance is careful and regular attention!
The following recommended preventive maintenance is based on tank cleaning machines working in
average conditions. However, you will appreciate that a tank cleaning machine, which has a rough and dirty
job to do, will need more frequent attention than one working in ideal conditions. We trust that you will adjust
your maintenance programme to suit.
Recommended Preventive Maintenance
Every 300 work hours disassemble the machine according to the instruction "Dismantling and Assembling"
(page 14-19).
Clean material build-up and deposits from the internal parts. Inspect and clean the individual parts with
Scotch-brite, S-Ultrafine, or chemical cleaner. Do not wipe with cotton waste, use always a non-fluffing cloth.
Special attention must be directed to the wear parts. To check which parts that are wear parts, please see
Reference Lists of Parts, page 23-24. Replace worn or damaged parts.
When holding components in a vice, use lead or aluminium jaws or jaws made from other soft material. If it is
necessary to knock any components, use a plastic hammer.
Never place parts directly on dirty floors or tables. Always place the parts on a piece of cloth, cardboard, etc.
Always perform all assembly/disassembly steps in the order described in this manual. Never assemble
components without previous cleaning. Work in a well-lighted work area.
Note: Recommended tightening torque for all screws: 4-5 Nm.
