10.3.3 Refrigerant charge - Connect the refrigerant gas cylinder to the male 1/4 SAE charge connector on the liquid line and allow a small amount of gas to escape in order to purge the connection hose of air. - The circuit must be charged exclusively with liquid; therefore, if the cylinder is not equipped with a dip pipe it must be turned upside-down. 10.4 ENVIRONMENTAL CONSIDERATIONS Units operating with R407C must be charged exclusively with liquid refrigerant by way of the charge connection on the liquid line. A unit that was originally factory charged with R407C cannot be charged with R22 (and vice versa)! Laws governing the use of substances detrimental to the ozone layer prohibit the dispersal of refrigerant gases in the environment, obliging users to recover refrigerants at the end of their useful life and consign them to the dealer or to specific collection centres. Refrigerant R407C IS mentioned among substances subject to special monitoring regimes established by law, and as such they are subject to the prescriptions indicated above. 11. TROUBLESHOOTING Use special care during maintenance work in order to limit the risk of refrigerant leakage as far as possible. The following pages contain a list of the most common causes that can result in the shutdown or anomalous operation of the chiller. Faults are arranged in accordance with easily identifiable symptoms. In relation to possible corrective action, adopt the maximum attention in the operations you intend to perform as overconfidence coupled with insufficient attention due to lack of expertise can lead to serious accidents. We therefore recommend that Blue Box or other skilled HV<strong>AC</strong> engineers are contacted to identify and correct the problem. Blue Box 52
SYMPTOM A) No compressor running. Fans stopped (display Off) B) No compressor running. Display On: ”OFF from external consent” C) No compressor running. Display On: ”OFF from supervision system” D) No compressor running. Display On: ”OFF” OPERATION COOLING HEATING PROBABLE CAUSE Blue Box 53 POSSIBLE CORRECTIVE <strong>AC</strong>TION ˜ ˜ No mains power Check presence of mains power ˜ ˜ Main power switch Off (position "O") Turn main power selector to position "I" ˜ ˜ No power to control circuits Check fuses FU50, FU51, FU52. Check operation of transformer ˜ ˜ Incorrect phase sequence (relay KA5 with only green LED lit) ˜ ˜ Relay KA5 with green and yellow LEDs off Invert two of the phase wires of the power supply line; when the unit is powered up again both the green and yellow LEDs should light Check fuses FU56; If fuses are OK replace phase sequence relay ˜ ˜ No external consent Check presence of external consent; if not present, bridge terminals 1 and 2 ˜ ˜ No consent from supervision system ˜ ˜ No consent from “on/off” key of user interface Activate operation from supervision system Press “on/off” key
