11--Introdução Foreword 1.1 Introduction 1.3 Emergency stop / Normal stop Units, manufactured to state-of-the-art design and implementation standards, ensure top performance, reliability and fitness to any type of air-conditioning systems. The emergency stop of the unit can be enabled using the master switch on the control panel (move down the lever). For a normal stop, press the relevant push-buttons.
English 2 - Safety 2.1 Foreword These units must be installed in conformity with the provisions of Machinery Directive 2006/42/EC, Pressure Equipment Directive 2014/68/EU, Electromagnetic Compatibility Directive 2014/30/EU, as well as with other regulations applicable in the country of installation. If these provisions are not complied with, the unit must not be operated.
2 - Safety (continued) disassemble connections, filters, joints or other line items 2.2 Definitions OWNER: means the legal representative of the company, body or individual who owns the plant where unit has been installed; he/she has the responsibility of making sure that all the safety regulations specified in this manual are complied with, along with the national laws in force.

2 - Safety (continued) 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. Remove Contact with skin 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.
2.8 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 - Safety (continued) 2.8 Safety regulations (continued) LUBRICANT OIL DATA SAFETY DATA: POE/PVE OIL 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.
Refrigerators are supplied assembled (apart from standard antivibrating rubber supports, that will be installed on site). The equipment are full of refrigerant and oil, in the quantity required for a proper operation. It is recommended to use a spacer to prevent cables from damaging the unit (see the figure). 3.1 Inspection When the unit is delivered, it is recommended to check it carefully and to identify any damage occurred during transportation. The goods are shipped ex-factory, at the buyer’s risk.
3 - Transport, Lifting and Positioning (continued) The eyebolts must be mounted on the unit whenever it shall be displaced and then lifted again. During the lifting and handling of the unit, be careful not to damage the finned pack of the coils positioned on the sides of the unit. WARNING WARNING WARNING 3.3 Anchoring The sides of the unit must be protected by cardboard or plywood sheets.
4.1 Positioning of the unit DANGER 4.2 Spring Isolator Installation Before installing the unit, make sure that the structure of the building and/or the supporting surface can withstand the weight of the appliance. The weights of the units are listed in Chapter 8 of this manual. n Prepare the base, that must be flat and plane. n Lift the appliance and insert shock absorbers as follows: These units have been designed for outdoor installation on a solid surface.
4 - Installation (continued) 4.3 External Water Circuit The expansion tank shall be dimensioned in such a way that it can absorb a 2% expansion of the total volume of the water in the plant (exchanger, pipelines, uses and storage tank, if available). The flow switch and the filter water, although not included in the supply, must always be fitted such as plant components. Their installation is mandatory for warranty.

8.4.1 Variable flow hydronic systems • Manual flow control 1. Note: When VPF works at 30 Hz, the absorbed power consumption of the pump is reduced by 80% compared to 50Hz pump operation. Application Provide the user with the required flow rate and hydraulic balance without the need of mechanical balancing valve but taking advantage of the energy consumption optimization of the pump using the frequency drive. 2. • Variable primary flow (Constant ΔP) 1.

DANGER 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 Do not inject refrigerant liquid into the LP side of the circuit. Be very careful, and charge the circuit properly. If the charge is insufficient, the efficiency of the unit will be lower than expected. (In the worst of cases the LP transducer may stop the unit.) 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 of authorised Service Centers.
9 - Maintenance (continued) 9.9 Electronic Expansion Valve 9.10 Evaporator The circuit of the unit is equipped with electronic expansion valve, with external equalizer The valve is shop-calibrated for an overheating of 5°C. Check at regular intervals that the water side of the heat exchanger is perfectly clean. To do this, measure the pressure drop, water side (see Section 8) or measure the temperature of the liquid leaving and entering the heat exchanger, and compare it to the evaporation temperature.
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. Component Number Fan 1 Flow switch 1 High pressure transducer 1 Low pressure transducer 1 Expansion valve 1 Gas filter 1 4 way valve 1 Electronic main board 1 Auxiliary circuit trasformer 1 Compressor contactor 2 Pump contactor 1 Water sensor 4 Air sensor 1 Auxiliary contact 4 Driver EEV 1 Fuses 4 11.
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.
