Turn ON the power supply and make sure WaterPump 16 is running.5. Check and make sure no water leaking at the tubeconnecting points.11.1.8 ReconfirmationWARNINGBe sure to switch off all power supply before performing each of thebelow checkings. Before obtaining access to terminals, all supplycircuits must be disconnected.11.1.8.1 Check Water Pressure*(0.1 MPa = 1 bar)Water pressure should not lower than 0.05 MPa (withinspects the Water Pressure Gauge 14 ). If necessaryadd tap water into Tank Unit. Refer to Tank unitinstallation instruction for details on how to add water.11.1.8.2 Check Pressure Relief Valve 13 Check for correct operation of Pressure ReliefValve 13 by turning on the lever to becomehorizontal. If you do not hear a clacking sound (due to waterdrainage), contact your local authorized dealer. Push down the lever after finish checking. In case the water keeps drained out from the unit,switch off the system, and then contact your localauthorized dealer.11.1.8.3 Check RCCB/ELCBEnsure the RCCB/ELCB set to “ON” condition beforecheck RCCB/ ELCB.Turn on the power supply to the Indoor Unit.This testing could only be done when power issupplied to the Indoor Unit.WARNINGBe careful not to touch parts other than RCCB/ELCB test buttonwhen the power is supplied to Indoor Unit. Else, electrical shockmay happen. Before obtaining access to terminals, all supplycircuits must be disconnected. Push the “TEST” button on the RCCB/ELCB. Thelever would turn down and indicate “0”, if itfunctions normal. Contact authorized dealer if the RCCB/ELCBmalfunction. Turn off the power supply to the Indoor Unit. If RCCB/ELCB functions normal, set the lever to“ON” again after testing finish.This product contains fluorinated greenhouse gasses.Refrigerant type: R410A (GWP=2088)Amount: For SXC09*3E8/SXC12*9E8 2.85 kg (5.9508ton CO 2 equivalent)For SXC16*9E8 2.90 kg (6.0552 ton CO 2equivalent)For SDC09*3E8/SDC12*9E8/SDC16*9E82.55kg (5.3244 ton CO 2 equivalent)(The amount do not include the additional refrigerantwhen refrigerating piping length extended. Pleaserefer to adhered label on outdoor unit for exactamount of refrigerant used and actual tonnes of CO 2equivalent.)11.1.9 Test Run1. Fill up the Tank Unit with water. For details refer toTank Unit installation instruction and operationinstruction.2. Set ON to the Indoor Unit and RCCB/ELCB. Then,for control panel operation please refers to air-to-water heatpump operation instruction.3. For normal operation, pressure gauge 14 readingshould be in between 0.05 MPa and 0.3 MPa.4. After test run, please clean the Water Filter Set 15 .Reinstall it after finish cleaning.11.1.9.1 Reset Overload Protector 11Overload Protector 11 serves the safety purpose toprevent the water over heating.
