By adjusting compressor running times, it prevents short-cycle protection cycles from starting and, in most cases, eliminates the need for a buffer tank by improving the reliability of the machine. The calculation of the minimum water volume is given for EUROVENT rated conditions, in cooling mode only. N.B.: Calculations of minimum volumes of chilled water are made for the following conditions: - chilled water temperature to evaporator: 12 C/7 C - condensation temperature: 45 C This value is applicable for most air conditioning applications (unit with fan coil units) Comment: For installations running with a low volume of water (assembly with air handling unit) or for industrial processes, the buffer tank is a required component. 120V 150V 200V 240V 300V 350V 400V 500V 540V 600V Min. system capacity (litres) 226 299 197 222 292 286 279 454 217 274 DYNACIAT POWER LGN 700V 800V 900V 1000V 1100V 1200V 1400V 1600V 1800V 2100V 2400V Min. system capacity (litres) 636 880 844 1146 1043 1346 1286 1735 1262 1336 1595 HEAT PUMPS - AIR CONDITIONING - REFRIGERATION - AIR HANDLING - HEAT EXCHANGE - NA 17.705 B 15

Installation recommendations n Water quality criteria to be respected N.B.: It is essential that an 800 micron water filter be placed on the unit's water inlet during installation. The quality of the water used has a direct impact on the correct and compliant operation of the water chiller and its service life. This is particularly true if the water used clogs or corrodes components or promotes the growth of algae or micro-organisms. The water must be tested to determine whether it is suitable for the unit and whether chemical treatment will suffice to make it of acceptable quality and if a water softening/demineralising system should be installed. The results of the analysis must confirm whether the site's water is compatible with the various materials used on the CIAT unit's circuit: - 99.9% copper tubes brazed with copper and silver, - threaded bronze couplings or flat steel flanges, depending on the unit model, - plate heat exchangers and AISI 316/DIN 1.4401 stainless steel connections brazed with copper and silver. N.B.: The guarantee shall be void if these instructions are not followed. n Lifting and handling The utmost safety precautions must be taken when lifting and handling the unit. Always follow the lifting diagram affixed to the unit and the installation, operation, commissioning and maintenance manual. Before attempting to lift the unit, make sure the path leading to its intended location is free from obstacles. Always keep the unit vertical when moving it. Never tip it or lie it on its side. n Choosing a location for the unit DYNACIAT POWER units are designed for installation in a machine room. Precautions should be taken to protect it from freezing temperatures. Special attention should be paid to ensure sufficient free space (including at the top) to allow maintenance. The unit must be placed on a perfectly level, fireproof surface strong enough to support it once charged. Noise pollution from auxiliary equipment such as pumps should be studied thoroughly. Depending on the room and its structure, potential noise transmission routes should be studied, with assistance from an acoustical engineer if necessary, before installing the unit. Flexible couplings MUST be placed over pipes (available as options). n Machine room ventilation According to the regulations in force in the place in which the machine is to be installed, the machine room must comply with certain ventilation rules for fresh air to ensure there is no risk of discomfort or hazard in the event of a refrigerant leak. n Assembly of separately supplied accessories: A number of optional accessories may be delivered separately and installed on the unit on site. Always follow the instructions in the user manual (Installation, Operation, Commissioning and Maintenance). n Electrical connections: Always follow the instructions in the user manual (Installation, Operation, Commissioning and Maintenance). All information concerning electrical connections is stated on the wiring diagrams provided with the unit. Always follow this information to the letter. Electrical connections must be made in accordance with best current practices and applicable standards and regulations. Electrical connections to be made on site: unit's electrical supply, outdoor operation authorisation (optional) information feedback (option). It should be noted that the unit's electrical system is not protected against lightning strikes. Therefore components to protect against transient voltage surges must be installed on the system and inside the electrical supply unit. 24 HEAT PUMPS - AIR CONDITIONING - REFRIGERATION - AIR HANDLING - HEAT EXCHANGE - NA 17.705 B

n Pipe connections: Always follow the instructions in the user manual (Installation, Operation, Commissioning and Maintenance) All pipes must be correctly aligned and slope toward the system's drain valve. Pipes must be installed to allow sufficient access to the panels and fitted with heat insulation. Pipe mountings and clamps must be separate to avoid vibrations and placing pressure on the unit. Water shut-off and control valves must be fitted when the unit is installed. - Pipe connections to be made on site:. system water supply with pressure-reducing valve,. evaporator and discharge, - Accessories essential to any hydraulic system must also be installed, such as: - a thermostatically-controlled valve for controlling the flow rate of cooling water placed at the condenser water inlet or outlet.. water expansion vessel,. drain nozzles at pipe low points,. exchanger shut-off valves equipped with filters,. air vents at pipe high points, - check the system's water capacity (install a buffer water tank if necessary),. flexible couplings on exchanger inlets and outlets,. thermometers on each water inlet and outlet to allow all the necessary checks during start-up and maintenance. N.B.: - Pressure in the water circuits below 4.0 bar. - Place the expansion vessel before the pump. - Do not place any valves on the expansion vessel. - Make sure the water circulation pumps are placed directly at the exchanger inlets. - Make sure the pressure of the water drawn in by the circulation pumps is greater than or equal to the required minimum NPSH, particularly if the water circuits are "open". - Test the water quality in accordance with the relevant technical requirements. - Take the necessary precautions to protect the unit and hydraulic system from freezing temperatures (e.g. allow for the possibility of draining the unit). If glycol is added to prevent freezing, check its type and concentration beforehand. - Before making any final hydraulic connections, flush the pipes with clean water to remove any debris in the network. n Refrigerant connections Performance levels are provided for a refrigerant connection between the LGN unit and the OPERA (7 m long). The maximum recommended length is 30 m, with a maximum height difference of 15 m. - Always follow the instructions in the user manual (Installation, Operation, Commissioning and Maintenance). - The pipes are made from refrigeration quality copper and in accordance with accepted engineering practice. - CIAT does not offer this equipment which is designed to be connected to a non-brand condenser or refrigerant connections, nor can CIAT provide system start-up services in this case. - The pipes must be carefully routed taking into account the constraints of the oil return to the compressor and pressure drops which could affect performance levels. n Commissioning Dynaciat machines must be commissioned by CIAT or a CIAT-approved firm. Always follow the instructions in the user manual (Installation, Operation, Commissioning and Maintenance). Partial list of precommissioning checks: - Correct positioning of unit, - Power supply protections, - Phases and direction of rotation, - Wiring connections on unit, - Direction of water flow in unit, - Cleanliness of water circuit, - Adjusting water flow rate to specified value, - Pressure in the refrigeration circuit, - Direction of rotation of compressors, - Water pressure drops and flow rates, - Operating readings. n Maintenance operations Specific preventive maintenance operations must be carried out regularly on the unit by CIAT-approved firms. The operating parameters are read and noted on a "CHECK LIST" form to be returned to CIAT. To do this, always refer to and follow the instructions in the user manual (Installation, Operation, Commissioning and Maintenance). You must take out a maintenance contract with a CIAT-approved refrigeration equipment specialist. Such a contract is required even during the warranty period.
