Date 15/09/2009 Version: 1.0 IMPORTANT POINTS ON SERVICE OPERATING SAFETY Please follow these instructions carefully: Unplug the unit to avoid any danger from electric shock before disassembling the unit for repair. If there is any sound of the refrigerant circulating when in operation, avoid touching the cooling coils. If you need to perform any welding or soldering, be sure you are in a well ventilated area. Only a qualified professional should perform any welding on the unit. When repairing the unit, the specifications listed in this manual must be strictly adhered to when replacing any components. When replacing any electrical components they should be factory approved units. Be sure that any electrical components are properly wired and in place. FLOW CHART FOR INSPECTING AND REPAIRING THE UNIT Electricity shutdown Check fuses on main switch Dehumidifier doesn't work Check if drain bucket water level switch is broken Can not dehumidify Humidity switch is broken Humidity switch is set on continuous operation Check if air filter is clogged Capacitors are faulty Compressor doesn't work Refrigerant is leaking Maintain & repair system Supply Nitrogen 15KG/CM2 from low pressure side and locate the leakage Use oxygen acetylene and 5% silver iron to fill cracks and holes Pump vacuum for at least 15 minutes After filling with refrigerant proceed to test run - 1- Over load protector is faulty TROUBLESHOOTING Problem Dehumidifier doesn't work Fan doesn't work Possible causes Solution Electricity shutdown or low voltage Wait for electricity to be restored Bad plug or a wire is broken Repair or replace Motor is broken Repair or replace Low voltage Call the local electricity company Compressor doesn't Still under the 3 min. protection Wait until if goes back to function after 3 min.work Can not dehumidify or the dehumidifcation volume is too low Loud noise and vibration Evaporator is frosted Compressor is broken Repair or replace Filter is dirty Clean filter Refrigerant is leaking Detect the leakage and fill with refrigerant. Low temp. and humidity Normal Uneven floor Move to level place or use blocks Motor or compressor is loose Tighten screws Sound of flowing water Normal, it is the sound when the refrigerant is flowing Filter is too dirty Clean filter Environment temp.is too low Stop use temporarily Drain bucket is broken Repair or replace Minor-moving switch is broken Repair or replace Dehumidification water overflows -2- APPEARANCE OUTLET FOR DEHUMIDIFIED DRY AIR AIR FILTER KNOB INTANK OF MOIST AIR DRAIN BUCKET TURNING WHEEL BUILT-IN CABLE STORAGE CONTINUOUS DRAINAGE HOLE FUNCTIONS CONTINUOUS OFF Dehumidifier continuously removing moisture. Dehumidifier stop removing moisture. NORMAL Humidity control between 50%-60%. BUCKET FULL LAMP When the water tank is full the full tank lamp will light up, the dehumidifier will stop operating immediately. DEFROST LAMP RUNNING LAMP When operating under low temperature for a short period, the dehumidifier will starting defrost process, the indicating lamp will light up. When the lamp lights up which means dehumidifier is operating. -3- TECHNICAL SPECIFICATIONS ITEM NARCISO 12 UNIT DEHUMIDIFYING CAPACITY L/ day 12 (at 30°C , 80%RH) POWER SOURCE V/Hz 220-240V/50Hz NOISE dB(A) 41 POWER INPUT W 260 CURRENT A 1.13 WIRE SPECIFICATION PHP-206,16A 250V H05VV-F VDE 3G0.75mm DIMENSIONS Mm 405W*632H*290D WEIGHT (Net) Kg 13.5 35D020-B1-AADM MODEL COMPRESSOR CURRENT ASS Y POWER INPUT A W MODEL HEAT EXCHANGER UNIT 233 LS-16D1-01 FAN MOTOR POWER INPUT 1.06 W 30 EVAPORATOR RxSxFPIxW 2R8S19FPI x 25.4mm CONDENSER RxSxFPIxW 1R8S21FPI x 12.7mm R-134a/g 150 REFRIGERANT CAPILLARY mm COMP O.L.P D2.2 x d1.2 xL1000 MRA12279-12095 Capacitor F/ V 8 / 450 WATER TANK CAPACITY L 5.2 -4- 2 REFRIGERATOR SYSTEM DIAGRAM CAPILLARY TUBE DRYER PTC(HEATER) EVAPORATOR CONDENSER FAN MOTOR COMPRESSOR ASS'Y FUSE T6.3AL 250V BROWN SCHEMATI C WIRING DIAGRAM CMP FAN MOTOR WHITE BLACK AC CORD RUN LAMP BLUE WHITE CAPACITOR FULL LAMP DEFROST LAMP SENSOR HUMIDITY SWITCH BLUE D6951-630 -5-
