C HAPTER 2
S AFETY
This machinery was designed to be safe in the use for which it was planned provided that it is installed, started up and maintained in accordance
with the instructions contained in this manual. The manual must therefore be studied by all those who want to install, use or maintain the unit.
The machine contains electrical components which operate at the line voltage, and also moving parts.
It must therefore be isolated from the electricity supply network before being opened. Maintenance operations involving work inside the machine
must be performed by skilled and adequately qualified personnel equipped with suitable protection means (active and passive, e.g. work gloves)
ton ensure work in maximum safety. Do not allow extraneous persons (such as children) where the machine is installed.
2.1 General
When handling or maintaining the unit and all auxiliary equipment, the personnel must operate with care observing all instructions concerning
health and safety at installation site.
ATTENTION
Most accidents which occur during the operation and maintenance of the machinery are a result of failure to observe basic safety rules or
precautions.
An accident can often be avoided by recognising a situation that is potentially hazardous.
The user should make sure that all personnel concerned with operation and maintenance of the unit and all auxiliary equipment have read and
understood all warnings, cautions, prohibitions and notes written in this manual as well as on the unit.
Improper operation or maintenance of the unit and auxiliary equipment could be dangerous and result in an accident causing injury or death.
We cannot anticipate every possible circumstance which might represent a potential hazard.
The warnings in this manual are therefore not all-inclusive.
If the user employs an operating procedure, an item of equipment or a method of working which is not specifically recommended, he must ensure
that the unit and auxiliary equipment will not be damaged or made unsafe and that there is no risk to persons or property.
Any improper use of the machine will relieve the manufacturer from any liability for possible personal injury or property damage.
Arbitrary modifications made to the unit will automatically invalidate all forms of guarantee provided by the manufacturer.
ATTENTION
The hot / cold water produced by MTA units cannot be used directly for domestic hygiene or food applications. In the
case of such applications, the installer is responsible for fitting an intermediate exchanger.
If the intermediate exchanger is not fitted, the installer should affix a notice stating "non-drinking water".
2.2 Liquids of the user circuit
The liquids of the user circuit must be compatible with the materials used. These can be water or mixtures of water and glycol, for example.
Additives and glycol suppliers must guarantee compatibility with the materials. For further information refer to 4.10 “Materials in contact with
the liquid to be cooled” .
ATTENTION
If the liquids of the user circuit contains dangerous substances (e.g. ethylene glycol) is very important to collect any liquid which leaks
because it could cause damages to the ambient. Furthermore, when the chiller is no longer used, dangerous liquids must be disposed of by
firms specialised and authorised for treating them.
2.3 Lifting and carriage precautions
Avoid injury by using a hoist to lift heavy loads.
Check all chains, hooks, shackles and slings are in good condition and are of the correct capacity.
They must be tested and approved according to local safety regulations.
Cables, chains or ropes must never be applied directly to lifting eyes.
Always use an appropriate shackle or hook properly positioned.
Arrange lifting cables so that there are no sharp bends.
Use a spreader bar to avoid side loads on hooks, eyes and shackles.
When a load is on a hoist stay clear of the danger area beneath and around it.
Keep lifting acceleration and speed within safe limits and never leave a load hanging on a hoist for longer than is necessary. The weight values
shown in the following table were obtained with the unit empty, pump P3 and axial fans.
The manufacturer does not supply bars, belts and lifting hooks with the unit.

Weight values are guideline, with the water circuit empty. The values may vary in relation to the configuration of the unit (pump type, supply
type, and ventilation type).
2.4 Installation precautions
The connections to be made are for the process water circuit. Use the electrical diagram accompanying this manual to for the connection to the
power grid.
2.5 Precautions during operation
Operation must be carried out by competent personnel under a qualified supervisor.
All the water piping must be painted or clearly marked in accordance with local safety regulations in the place of installation.
ATTENTION
Never remove or tamper with the safety devices, guards or insulation materials fitted to the unit or auxiliary equipment.
All electrical connections must comply with local codes.
The unit and auxiliary equipment must be earthen and protected by fuses against short-circuits and overloading.
When mains power is switched on, lethal voltages are present in the electrical circuits and extreme caution must be exercised whenever it is
necessary to carry out any work on the electrical system.
Do not open any electrical panels or cabinets or touch any electrical components or associated equipment while voltage is applied unless it is
necessary for measurements, tests or adjustments. Such work should be carried out only by a qualified electrician equipped with the proper tools
and wearing appropriate body protection against electrical hazards.
2.6 Maintenance and repair precautions
ATTENTION
When disposing of parts and waste material of any kind make sure that there is no pollution of any drain or natural water-course and that no
burning of waste takes place which could cause pollution of the air. Protect the environment by using only approved methods of disposal.
Keep a written record of all maintenance and repair work carried out on the unit and auxiliary equipment. The frequency and the nature of the
work required over a period can reveal adverse operating conditions which should be corrected.
ATTENTION
Use only refrigerant gas specified on the specification plate of the unit.
Make sure that all instructions concerning operation and maintenance are strictly followed and that the complete unit, with all accessories and
safety devices, is kept in good working order. The accuracy of pressure and temperature gauges must be regularly checked. They must be
renewed when acceptable tolerances are exceeded.
ATTENTION
Do not weld or carry out any operation which produces heat near a system which contains oil or flammable liquids. The systems which may
contain oil or flammable liquids must be completely drained and cleaned (with steam, for example), before carrying out these operations.

D ESCRIPTION
4.1 Components
The data relating to the materials refer to standard machines. In case of particular units special materials are used, so it is necessary to refer to the
data on the offer.
The machines essentially consist of the following components:
• Refrigerant compressor
• Condenser
• Evaporator
•Tank
•Pump
• Frame/outer panelling
• Electronic controller
4.2 Cooling circuit
Models TAEevo have a single refrigerant circuit with one or two compressors connected in parallel (tandem).
The circuits consist of the following components:
• refrigerant fluid used R407C;
• piston hermetic compressor or scroll compressor;
• fan pressure switch with on/off regulation;
• pressure switches for high and low refrigerant pressure;
• high pressure transducer for fan electronical regulation and for unloading (NOT present with 460/3/60 supply, centrifugal fans
and in TAEevo015÷020);
• liquid solenoid valve (with prismatic tank and plate-type evaporator);
• thermostatic throttle valve with external equalization (in models without prismatic tank present only from TAEevo031);
• dryer filter;
• liquid flow sight glass (in models without prismatic tank present only from TAEevo031);
• lamination capillary (only for TAEevo015÷020);
• refrigerant manometers (TAEevo031);
• Schrader service valves;
Consult the enclosed drawings for additional information.
4.3 Compressors
All the machines are equipped with piston or SCROLL hermetic compressors, which are distinguished for their high energy efficiency, low
vibrations and consequent silence in normal operation.
They are cooled by the aspirated gas, protected against overheating of the windings by an internal module that monitors their temperature and,
upstream, by magnetothermic circuit breakers. These components are housed in a closed, but easily accessible, compartment.
4.4 Condenser
Condensation occurs through fin-pack coils consisting of copper tubes and collectors, aluminium fins and shoulders in galvanised sheet.
4.5 Evaporator
The evaporator is a finned pack type; the water flows in contact with the finned surface and at a speed that guarantees low pressure drops, while
the refrigerant fluid flows inside the tubes.
A plate exchanger can be fitted as an alternative.
In the TAEevo models, the exchanger is protected against the formation of ice, caused by low evaporation temperatures, through an anti-freeze
function in the electronic controller. A probe monitors the temperature of the evaporator outlet water. If it is necessary to achieve a negative
ambient/water temperatures, a mixture of water and glycol must be used.
To drain the circuit, see Chapter 9.4 “Emptying the process water circuit” .
4.6 Tank
The storage tank is cylindrical.
Alternatively a prismatic atmospheric tank can be supplied.
The tank can be protected against freezing by means of an electric heater managed by the electronic controller. A level sensor in the tank serves
to signal low water level conditions. The standard supply includes anti-condensation cladding, a drain valve and an air bleed valve. An internal
bypass between the water delivery and return connections, makes it possible to read the anti-freeze probe if the unit's process water inlet and
outlet connections are inadvertently closed. In this case the unit stops due to tripping of the antifreeze alarm and the shut-off valves must be
reopened.
The bypass serves exclusively to allow an antifreeze alarm to trip (if present) and to allow the pump to run with a reduced water flow rate
without damage. It is advisable to avoid repeated antifreeze alarm trip cycles in the foregoing conditions.

4.7 Pump
Centrifugal pumps are installed and it is possible to choose between 2 different types, which provide two different pressures based on
requirements (a 3 or 5-barg pump). It is also possible to have units without pump.
The tandem pump can be installed in certain models.
The management procedure is manual. The selector for pumps rotation is located inside the electrical cabinet.
For more information consult the attached diagrams.
The pump seals are made of ceramics/treated carbon/EPDM.
ATTENTION
Bleed the circuit by unscrewing the bleed cap on the pump whenever the water circuit is filled .See 5.4 “Collegamenti idraulici” .
NOTE
The pump must never run dry.
4.8 Fans
Axial fans
The fans of axial type consist of a die-cast aluminium fan with sickle profile.
The protection rating of the fans is IP54.
The protection rating of the fans is IP44 for TAEevo015÷020.
All fans have “F” insulation class to assure the external working with all types of climates. The assembly is completed with a superior (support
to the fan) safety protection grill.
Centrifugal fans (NOT present in models with 460/3/60 supply)
Can be installed exclusively on models higher than TAEevo031.
These are double drive fans with the fanwheel coupled directly to the motor shaft and they feature ON/OFF control. The delivery port is located
on the top of the unit.
The delivery direction can be modified on models TAEevo201÷351.
4.9 Casing
The base, uprights and panels are made of galvanized carbon steel and held together by screws and/or rivets. All panels undergo a phosphor
degreasing process followed by epoxy polyester powder coating.
The frame is designed to allow easy access to all machine components.
With the prismatic atmospheric tank process water
filling is performed utilising a kit comprising a semi-
transparent plastic container secured to the rear of the
machine. In steady-state operating conditions the
liquid level must be about half way up the container.

“Safety“ in this manual.
5.1 Inspection
Immediately after uncrating, inspect the unit.
5.2 Positioning
1. The unit may be installed both outdoors and indoors.
2. If installed indoors, the room must be well ventilated and with a sufficient height which allows the air to be expelled by fans. In
some cases it may be necessary to install fans or extractors to limit the temperature of the room.
3. The minimum and maximum working ambient temperature are specified on the unit data plate. In extreme temperature conditions,
the protection devices may trip.
4. The machine must be positioned on any flat surface capable of supporting its weight.
5. Leave at least one metre around the unit to permit access during service operations.
6. Do not obstruct or disturb the condenser's flow of thermal exchanging air.
5.3 Antifreeze protection
Even if the minimum working ambient temperature is above 0°C it is possible for the machine - during stoppages in the cold seasons - to find
itself in an environment with a temperature below 0°C.
In these cases, if the machine is not emptied, antifreeze (ethylene glycol) must be added in the following percentages to prevent the formation of
ice:
Add the following anti-freeze (ethylene glycol) percentages in order to avoid freezing when operating at low water outlet temperature:
ATTENTION
Carry out the level sensor calibration when the unit is activated the first time. Repeat the operation each time the composition of the process
liquid changes.
