The parts subjected to normal wear and agingneed to be serviced for ensuring full reliability of the operations. These parts may be mechanical components or electrical components. The interval at which the maintenance should be carried out depends upon the following factors: 1. The number of short-circuit interruptions 2. The switching frequency 3. The actual service time The actual conditions of use in terms of the frequency of operations, environment and severity of switching duty vary so much that it is impossible for the manufacturer to give detailed guidelines to the user concerning the frequency of maintenance.

  • How To Vacuum AC System In Your Car - The DIY Process

    Preparing and Identifying Service PortsHooking Up The Manifold GaugeMaking The ConnectionsThe Vacuuming ActionTo begin with, park your car in a garage or anywhere, where the surface is flat. Do not start the car or the AC system within. Next, you need to wear gloves and a pair of protective glasses. The next thing that would come in handy is a set of a manifold gauge. Before you attach it, you need to make sure where the high and the low services ports lie. The high service port is larger than the lower counterpart and is positioned amid the orifice tube or the expansion valve and the condenser. When you follow the AC’s compressor linkages and to the bottom of the car, a nozzle would be visible. This very nozzle is the low side service port that is stuck amid the compressor and the evaporator. Now the real work to vacuum AC systemcan start. SEE MORE : 1. Why does the car AC smell bad?
