7.1 Introduction SYSCREW WATER EVO units are designed for indoor installation. They can be equipped with one or two circuits (depending on the model) and may be used to cool water to the evaporator and / or to heat water to the condenser. When heating capacity is not the required useful effect, is is necessary to match the unit with a cooling tower or well water in order to reject condenser heat load. The units are suitable for indoor installation.

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 Do not inject refrigerant liquid into the LP side of the circuit. Be very careful, and charge the circuit properly. WARNING If the charge is insufficient, the efficiency of the unit will be lower than expected. In the worst of cases the LP pressure switch may be activated, resulting in the halting of the unit. WARNING 9.
9 - Maintenance (continued) 9.7 Sight glass 9.9 Evaporator 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. Check at regular intervals that the water side of the heat exchanger is perfectly clean.
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 HP pressure switch 2/4 LP pressure switch 2/4 Gas filter 1/2 Electronic expansion valve 1/2 Auxiliary relays 2 Compressor’s fuses 3/6 Auxiliary fuses 6 Set of compressor contactors 1 Water sensor 2 Electronic card 1 Keyboard 1 Compressor oil resistor 1/2 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.
