7. START-UP 7.1 PRELIMINARY CHECKS – Check that the electrical connections have been made correctly, and that all terminals are well tightened. – Check that the voltage on the RST terminals is 400 V ± 5% (or the unit’s rated value, in the event of units supplied to run on non-standard power supplies). If the mains voltage is subject to frequent fluctuations, consult our Engineering Department to discuss the necessary protection systems. – Check that the display shows the gas pressure in the refrigerant circuit. – Inspect the unit for refrigerant leaks using a leak detector if necessary. – Check that the crankcase heaters are correctly supplied with power. Significant leakage of R407C refrigerant in the gaseous state will alter the percentages of the remaining mixture with consequent fall-off of performance. The heaters must be connected at least 12 hours before starting the unit; the heaters are automatically connected when the main disconnect switch is set to the ON position. – Verify that heaters are working correctly: after the warm up period the crankcase must be warm to the touch and must have at least a temperature 10 - 15 °C higher than ambient temperature. – Check that all hydraulic connections are correctly installed and all indications on unit labels are observed. – Check that the hydraulic system has been vent to eliminate any air remaining; charge it gradually and open the vent devices on the upper part, provided at the care of the installer together with an expansion tank of a proper size. Warning: before starting up the unit check that all the closing panels are in position and secured with the relative screws. <strong>Air</strong> Blue • 24
8. STARTING THE UNIT Fixed protections – The protections are positioned and fixed in a solid manner. – Their opening requires the use of specific tools. They do not stay in place without the fixing devices. 8.1 SEASONAL STOP – Disconnect the power supply via main switch/main disconnect switch – Drain the system circuit (unless it contains a water/glycol solution) – When the unit is to be restarted repeat the initial start-up procedure 8.2 EMERGENCY STOP Emergency stops are obtained by turning the red colour main disconnect switch on the electrical panel to position 0. Turning the main disconnect switch to position 0, the entire unit is disconnected from the power. If the unit fails to start: do not change internal electrical connections on penalty of immediate invalidation of the warranty. During idle periods do not disconnect the unit from the power supply (the compressor crankcase heaters must remain switched on in these intervals). Disconnect the unit from the power supply only in the event of prolonged disuse (e.g. seasonal shutdowns). Caution: to stop the unit, do not disconnect the power supply via the main switch of the machine: this device is used to to shut off power supply when there is no current transit, i.e. when the unit is set to OFF. Also if the power supply to the machine is shut off completely, the crankcase heaters would not be powered, with the risk of impairing compressor operation on restart. <strong>Air</strong> Blue • 25
