| 1 | Carrying out comprehensive maintenance of window and split type air conditioners, refrigerators, deep freezers, desert coolers and water purifiers (RO/UV/UF type) including periodic servicing, preventive maintenance and attending breakdown complaints. The work includes dismantling wherever required, thorough cleaning of filters, evaporator and condenser coils using suitable chemical solution, cleaning of blower, fan motor, drain tray and drain pipe including removal of choke and flushing. Checking, testing and servicing of compressors, fan motors, blowers, thermostats, relays, overload protectors, contactors, PCB, selector switches, SMPS, solenoid valves, RO pumps, UV lamps, membranes and allied components. Attending faults such as inadequate cooling, noise, vibration, water leakage, gas leakage etc., including leak detection using nitrogen pressure, rectification by brazing of copper tubing, vacuuming and charging of suitable refrigerant gas and topping up as required. Including replacement of minor spares such as capacitors, thermostats, relays, wiring, lugs, drain pipes, insulation tape, fasteners, rubber parts, filter candles, carbon filters and other consumables required for proper functioning of equipment. For water purifiers, work includes cleaning/ flushing of complete system, checking and servicing of RO membrane, UV lamp, sediment and carbon filters, pipelines, storage tank, ensuring proper purification and discharge. Checking of complete electrical system including wiring, earthing, insulation, tightening of terminals and ensuring safe operation. Including dismantling and refixing of units (if required during maintenance), complete testing, commissioning and handing over in satisfactory working condition, complete all as specified and directed.
