2.8 Safety regulations REFRIGERANT DATA Toxicity SAFETY DATA: R410A Low. If sprayed, the refrigerant is likely to cause frost burns. If absorbed by the skin, the danger is very limited; it may cause a slight irritation, and the liquid is degreasing. Unfreeze the affected skin with water. Contact with skin Remove the contaminated clothes with great care - in the presence of frost burns, the clothes may stick to the skin. Wash with plenty of warm water the affected skin.
2 - Safety 2.8 Safety regulations (continued) REFRIGERANT DATA General precautions Respiratory system protection SAFETY DATA: R410A Do not inhale concentrated vapours. Their concentration in the atmosphere should not exceed the minimum preset values and should be maintained below the professional threshold. Being more weighty than the air, the vapour concentrates on the bottom, in narrow areas. Therefore, the exhaust system must work at low level.
2.8 Safety regulations (continued) LUBRICANT OIL DATA SAFETY DATA: POLYESTER OIL (POE) Classification Not harmful. Contact with skin May cause slight irritation. Does not require first aid measures. It is recommended to follow usual personal hygiene measures, including washing the exposed skin with soap and water several times a day. It is also recommended to wash your overalls at least once a week. Contact with eyes Wash thoroughly with a suitable solution or tap water.
3 - Transport, Handling and Storage Units are supplied fully assembled and tested (except for accessories supplied loose in the units – absorbers, filter, etc.). They are ready to be installed and started on the field. Space requirements request to handling R410A units are only charged with liquid refrigerant and with oil in the quantity required for operation.
n Never store the units in a room where temperature is above 50 °C (R410A units) or where the units are directly exposed to the sunlight. n Minimum storage temperature is -25 °C. n It is recommended to leave the finned coils covered to protect them against any risk of corrosion, especially if building works are still in progress. n Store the units in areas where minimum activity is likely to take place in order to avoid any risk of accidental damage. n Never use steam to clean the unit. 3.

4 - Installation 4.4.1 Features WARNING Before filling the installation, remove any impurity, such as sand, crushed stones and welding scales, coating drops and any other material which might damage the evaporator. The kit will include an Antifreeze Electric Heater, a drain valve, an automatic filling unit and an automatic air vent. No pump is arranged on the kit since it is mounted on the unit.
4.5 Power supply 4.4.2 Supplied Material The kits will be supplied with pipelines ready for installation. An antifreeze resistance with wiring, an automatic water filling valve, a 3 bar safety valve, a drain valve and a vent valve have already been assembled. DANGER Before carrying out any operations on the electrical system, make sure that the unit is deenergized. Hydrokit is shipped with a film to protect it from atmospheric agents. Packaging has been designed in order to stack it up. 4.4.
4 - Installation Antifreeze Resistance Wiring 4.6 Electrical connections For 3-phase systems, check also that the unbalance between the phases does not exceed 2%. To perform this check, measure the differences between the voltage of each phase couple and their mean value during operation. The maximum % value of these differences (unbalance) must not exceed 2% of the mean voltage. The unit must be installed on site according to the usual procedures and standards applicable in the place of installation.

7.1 General Information Evaporators (SyScroll Air CO) Units are one-block type with one refrigerant circuit. They are intended to cool down the water required for any air-conditioning application as well as any other fluid, such as for example glycol water. Evaporators are made of stainless steel plates. They are thermally insulated by means of a thick flexible insulating mattress with closed cells.

DANGER Check the temperature of the leaving fluid When the recovered refrigerant cannot be reused, return it to the manufacturer. Do not throw away the waste oil of the compressor, because it contains refrigerant in solution. DANGER The waste oil must be returned to the manufacturer. Unless otherwise specified, the operations described below may be carried out only by a trained maintenance operator. 9.
9.3 Refrigerant charge 9.5 Condenser The condenser’s coils consist of copper pipes and aluminium fins. In the presence of leaks caused by any damage or shock, the coils shall be repaired or replaced by one authorised Service Center. To ensure the effective and correct operation of the condenser coils, it is important to keep the condenser’s surface perfectly clean, and to check that there is no foreign matter, such as leafs, wires, insects, waste etc.
9 - Maintenance 9.8 Sight glass Overheating calculation (S): The sight glass is used for inspecting the refrigerant flow and the humidity % of the refrigerant. The presence of bubbles indicates that the dehydrating filter is clogged or the charge insufficient. S = Tse - Tsa Overheating is regulated through the thermostatic expansion valve. Make the adjusting screw follow a complete turn, and operate the appliance for five minutes. A colour indicator is positioned inside the sight glass.
The table below lists the anomalies of operation of the unit, the relevant causes and the corrective measures. For anomalies of any other type or not listed, contact one of authorised Service Centre for technical assistance. Anomaly Cause Operation The unit continues to work, but without cooling Insufficient charge of refrigerant. Refill. The dehydrating filter is clogged. Replace. Ice on the suction line Wrong calibration of overheating. Excessive noise Increase overheating. Check the charge.
11 - Spare Parts 11.1 Spare part list The table below shows the list of spare parts recommended during the first two years of operation.
After draining operations, the piping of the hydraulic networks can be disconnected and disassembled. During the draining of the refrigeration circuits, do not let the refrigerant overflow in the surrounding atmosphere. DANGER Once they have been disconnected as specified, the packaged units can be disassembled in a single piece.
