4 - SAFETY INSTRUCTIONS
To avoid any risk of accident during installation, start-up and adjustments, the following equipment specics must be taken into
account:
■Pressurised refrigeration circuits
■Presence of refrigerants
■Presence of electrical voltage
Only experienced and qualied persons may work on such equipment.
The recommendations and instructions in this manual and on each drawing provided with the unit must be followed.
In the case of units with pressure equipment or components, we recommend that you contact your professional organisation for
information on the regulations that apply to operators or owners of pressure equipment or components. The characteristics of this
equipment/these components are given on the name plate or in the regulatory documentation supplied with the products.
A re protection device is tted as standard on all units.
Make sure the main disconnect switch in the unit's electrical panel is in the OFF position before working on the
unit.
5 - MACHINE COMPLIANCE
Refer to the "Declaration of conformity" document supplied with your equipment.
6 - WARRANTY
The warranty is effective for a period of 12 months from the date the unit is rst commissioned into service provided said date
occurs within three months of the invoice date.
It is effective for a period of 15 months from the unit invoice date in all other cases.
NOTE: Refer to our general terms and conditions of sale for further information.
7 - UNIT LOCATION
These units are typically used for refrigeration and are not required to withstand earthquakes. Earthquake resistance has therefore
not been checked.
Before setting up the unit in its intended location, the installer must check the following points:
■These units are designed to be installed and stored inside a machine room that is sheltered from frost and the elements. Failure
to do so will incur the loss of the manufacturer's warranty.
■The surface area of the ground or structure must be strong enough to bear the unit's weight.
■The unit must be perfectly level.
■There must be sufcient free space around and above the unit to allow servicing and maintenance (see dimensional drawing
provided with unit).
■The room housing the unit must comply with the requirements of regulation EN 378-3 and other specications applicable at the
installation site.
■The selected location must be above ood level.
■Allow for drainage of defrosting water.
■Sound level:
-Our units are designed to operate quietly.
-In the installation design, you must take into account the interior environment for radiated noise and the building type for airborne
and solid-borne noise transmission.
-To ensure vibrations transmitted by solid materials are reduced as much as possible, it is strongly recommended to t anti-
vibration mounts between the unit support and frame (see the section on anti-vibration mounts), as well as exible couplings
on the hydraulic piping.
-Have an analysis carried out by an acoustics engineer.
The ambient temperature must not exceed 50°C during the unit's off cycles.

8 - HANDLING AND POSITIONING
To raise the unit, attach the slings to the designated handling holes.
The data relating to the centre of gravity and the position of the anchorage points are given on the dimensional drawing.

POWER
Holes for handling
Ø 35.2 mm
The unit can be handled with a forklift truck (check the maximum permissible load of the forklift).
In this case, it is important that the necessary precautions be taken to avoid the unit sliding on the forks of the forklift. You must
observe the instructions given on the label afxed to the unit. Failure to observe these instructions may result in the unit tipping
over and causing physical injury.
■Attach the slings only to the anchorage points intended for this purpose and which are designated on the unit.
■Use slings with a suitable lifting capacity and follow the lifting instructions on the drawings provided with the
unit.
■Caution: The centre of gravity is not necessarily at the middle of the unit and the forces applied to the slings
are not always identical.
■Raise and set down the unit carefully. Take care not to tilt it by more than 15°, as this could adversely affect
its operation.
■To avoid damaging the casing, use textile slings with shackles.
■Use a frame with an adjustable centre of gravity to keep the slings away from the top of the unit.
■Always protect the unit casing (panels, posts, front access door) from damage during handling. Only the base
frame is designed to withstand handling.
■Safety when lifting can only be guaranteed if all these instructions are followed.
Otherwise, there is a risk of damage to the equipment and personal injury.

on the water outlet temperature.
Example:
For a water outlet temperature of +5°C
■The minimum TΔ is 2.6°C, which gives a water temperature of 7.6/5°C
■The maximum TΔ is 6°C, which gives a water temperature of 11/5°C
If the temperature difference calculated is outside the two curves, contact us.

12 - MAIN COMPONENTS OF THE REFRIGERATING CIRCUIT
Compressor
The DYNACIATPOWER units use hermetic SCROLL compressors.
Oil
The compressor is lubricated with a polyester oil, (POE) type
160SZ for the DYNACIATPOWER 700 V to 1200 V chillers. This
oil will be the 3MAF (32 cSt) type for the DYNACIATPOWER 1400
V to 2400 V chillers.
If necessary, top up the compressors with ICI Emkarate RL 32
CF oil or Mobil EAL Arctic 22 CC oil if no 3MAF is available for
R410A models.
Refrigerant
The DYNACIATPOWER 700 V to 2400 V use R410A.
The Global Warming Potential (GWP) is 2088 GWP for R410A,
in compliance with standard EN378-1.
Exchangers
With the DYNACIATPOWER, the evaporators and condensers are
double-circuit brazed-plate heat exchangers.
The evaporators are provided as standard with 19 mm
polyurethane foam insulation, adapted for operation with low-
temperature brine solution below 0 °C.
The heat-transfer medium must be filtered and internal
inspections must be carried out.
Repairs or modications of any kind to the plate heat exchangers
are prohibited. CIAT only authorises replacement of the heat
exchanger by a qualied technician using original equipment. If
the heat exchanger is replaced, this must be noted in the
maintenance booklet.
Expansion valve
Expansion valves have a load for the thermostatic element (MOP)
to obtain the maximum evaporation pressure in order to protect
the compressor.
The DYNACIATPOWER 700 to 1600 models are tted as standard
with one-piece hermetically-sealed thermostatic expansion
valves and the 1800 to 2400 models are tted with electronic
expansion valves that are set in the factory.
Every unit is fitted with one-piece hermetically-sealed
thermostatic expansion valves that are set in the factory to
maintain superheat of 5-7 °C under all operating conditions.
Dryer
Every unit is tted as standard with a dehumidier lter (the lter
unit has a replaceable cartridge) to keep the refrigerating circuit
clean and free of moisture. The dryer lter consists of aluminium
oxide and a molecular sieve that neutralises any acids in the
refrigeration circuit.
Liquid sight glass
Located on the liquid line just after the lter dryer, the liquid sight
glass is used to monitor the charge in the unit and to check for
moisture in the circuit. Bubbles in the sight glass mean that the
refrigerant load is insufcient or that non-condensable gases are
in the refrigeration circuit. If the sight glass indicator paper
changes colour, there is moisture in the circuit.
Some of the sight glasses may turn yellow when the
machine is powered off, as their sensitivity is
affected by the uid temperature.
The sight glasses should return to green after the
unit has been operating for a few hours.
If the sight glasses remain yellow, there is excessive
moisture in the circuit. A specialist intervention is
required.
