1. 1 Reading Electrical & Refrigerant Drawings

2. 2 General An electrical drawing shows the components of the circuit as simplified standard symbols, and the power and signal connections between the devices. Arrangement of the components interconnections on the diagram does not correspond to their physical locations in the finished device. It is used for the design, construction and maintenance of electrical and electronic equipment.

4. 4 Cartouche

5. 5 Unit Configuration C version  Cooling only Uniflair units have 4 different configurations that hit with electrical options: D version  Cooling + Humidification T version  Cooling + Heating H version  Cooling + Humidification + Heating

6. 6 Electrical Symbols Junction of conductors Manual switch Automatic switch Switch Multiple switch Thermal protection Wiring connections Earth High temperature thermostat Low temperature thermostat High pressure switch Low pressure switch Customizable switch Switches

7. 7 Electrical Symbols Power devices Sensors Other components Motor PumpCompressor Heating element Temperature probe Pressure transducer Humidity probe Transformer Capacitor Fuse Three (or more) Terminal devices Indicator lamp

8. 8 Denominations The main electrical components have a particular denominations, with a multilanguage description, in order to make the reading easier.
