8 - Technical Data (continued) 8.7 Space requirements E SPAC FREE 2 mt 2 mt 2 mt 2 mt 3,3 mt 2 mt The units are air-cooled and are designed for outdoor application. Adequate space around chillers is mandatory, as shown in the pictures below - to guarantee the proper air flow through the condenser coils, since warm air recirculation and coil starvation may cause the degradation of performances or, in the worst cases, the unit shutdown for high pressure.
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 - Maintenance (continued) 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.
9.6 Fans 9.9 Electronic expansion valve The fans of the condenser, of axial type, are complete with impeller with aerodynamic profile blades and a cylindrical nozzle. The motor’s bearings are lubricated forever. The circuit of the unit is equipped with electronic expansion valve. Before starting the appliance, after any maintenance operations involving the disconnection of 3-phase connections, check that the direction of rotation of the fans is the one indicated by the arrow (upward air current).
