Personality Type

  • Enterprising / Conventional


  • Electricity

    Understand the principles of electricity and electrical power circuits, as well as the associated risks.

  • Mechanics

    Theoretical and practical applications of the science studying the action of displacements and forces on physical bodies to the development of machinery and mechanical devices.

  • Refrigerants

    The characteristics and properties of the different fluids used in heat pump and refrigeration cycles.

  • Fluid mechanics

    The characteristics and properties of fluids, including gases, liquids and plasmas, at rest and in motion, and the forces on them.

  • Heating, ventilation, air conditioning and refrigeration parts

    The different parts constituing heating, air conditioning and refrigeration systems such as the different valves, fans, compressors, condensers, filters and other components.

  • Electrical wiring plans

    Pictorial representation of an electrical circuit. It shows the components of the circuit as simplified shapes, and the power and signal connections between the devices. It gives information about the relative position and arrangement of devices and terminals on the devices, to help in building or servicing the device. A wiring diagram is often used to troubleshoot problems and to make sure that all the connections have been made and that everything is present.

  • Hydraulics

    The power transmission systems that use the force of flowing liquids to transmit power.

  • Thermodynamics

    The branch of physics that deals with the relationships between heat and other forms of energy..


  • Use measurement instruments

    Use different measurement instruments depending on the property to be measured. Utilise various instruments to measure length, area, volume, speed, energy, force, and others.

  • Install heating boiler

    Place heating, ventilation, air conditioning and refrigeration boilers, which heats up water and circulates it through a closed radiator system to distribute heat around a structure. Connect the boiler to a source of fuel or electricity and to the circulation system. Connect it to the water supply if it features an automatic filling system. Configure the boiler.

  • Maintain electrical equipment

    Test electrical equipment for malfunctions. Take safety measures, company guidelines, and legislation concerning electrical equipment into account. Clean, repair and replace parts and connections as required.

  • Install electrical and electronic equipment

    Install equipment which is dependent on electric currents or electromagnetic fields in order to work, or equipment to generate, transfer or measure such currents and fields. This equipment includes switchboards, electric motors, generators or direct current systems.

  • Conduct routine machinery checks

    Check machinery and equipment to ensure reliable performance during use and operations in worksites.

  • Install air conditioning device

    Install air conditioning devices, which remove heat, and often moisture, from the air through a variety of mechanisms. Create the necessary openings through walls and floors and place the device. Connect it to a power supply. Configure the device.

  • Operate welding equipment

    Use welding equipment to melt and join together pieces of metal or steel; wear protective eyewear during the working process.

  • Use testing equipment

    Use equipment to test performance and operation of machinery.

  • Install ventilation equipment

    Install equipment to enable the ventilation of a structure. Mount fans and install air inlets and outlets. Install ducts to permit the transfer of air. Configure the ventilation system if it is electronically controlled.

  • Install heating, ventilation, air conditioning and refrigeration ducts

    Install ducts to deliver and remove air. Determine whether the duct should be flexible or not, and select the appropriate material based on projected usage. Waterproof and airproof the duct and insulate it against temperature influence to ensure maximum efficiency and prevent contamination with mould. Make the correct connections between the ducts and endpoints.

  • Operate soldering equipment

    Use soldering equipment to melt and join together pieces of metal or steel, such as a soldering gun, soldering torch, gas-powered iron, and others.

  • Operate hand drill

    Use a hand drill to make holes in various types of material such as stone, brick and wood. Take care to use the appropriate equipment, settings, drill bit and pressure for the task.

  • Perform maintenance on installed equipment

    Perform the maintenance on installed equipment on-site. Follow procedures to avoid uninstalling equipment from machinery or vehicles.

  • Install heating furnace

    Place a furnace which heats air to be distributed around a structure. Connect the furnace to a source of fuel or electricity and connect any air ducts to guide the heated air. Configure the furnace.

  • Handle refrigerant transfer pumps

    Handle the different transfer pumps used to keep a refrigerant in the liquid phase at the right pressure for an optimal accuracy and speed of the charging station.

  • Operate hot glue gun

    Operate the electric machine used to apply hot melt adhesive to join two pieces of material.

  • Apply proofing membranes

    Apply specialised membranes to prevent penetration of a structure by dampness or water. Securely seal any perforation to preserve the damp-proof or waterproof properties of the membrane. Make sure any membranes overlap top over bottom to prevent water from seeping in. Check the compatibility of multiple membranes used together.

  • Maintain electronic equipment

    Check and repair electronic equipment. Detect malfunction, locate faults and take measures to prevent damage.

  • Record test data

    Record data which has been identified specifically during preceding tests in order to verify that outputs of the test produce specific results or to review the reaction of the subject under exceptional or unusual input.

  • Work ergonomically

    Apply ergonomy principles in the organisation of the workplace while manually handling equipment and materials.

  • Resolve equipment malfunctions

    Identify, report and repair equipment damage and malfunctions; communicate with field representatives and manufacturers to obtain repair and replacement components.
