Each time a regulated slice reaches full output, the demand is passed on to the next slice, which starts operating at full capacity.
  • Page 35 6.2 HEATER POWER CONNECTION AND CURRENT PROTECTION The power supply connection must be made using a separate switchboard, which is not supplied by VTS. The heater connection should be made in such a way that the heater cannot be switched on when the fan is not switched on - this is ensured by factory-fitted, series-connected safety devices in the form of a thermostat and pressure switch, which prevent the heater from being switched on if the temperature and air flow conditions are not met.

  • Page 39 6.3 THERMAL CUT-OFF (THERMIC) The functionality of the thermostat is based on the properties of the bimetallic element - it causes the contacts of the heater control circuit to open when the air temperature near the thermostat is 65°C. After an emergency shutdown, the heater automatically switches on when the air temperature drops by 20°C.
  • Page 40 6.4 DIFFERENTIAL PRESSURE SWITCH The differential pressure switch is another safety element, in addition to the thermostat, which prevents the heater from operating under unallowable conditions. It prevents the heater from switching on if the pressure generated by the fan units on the supply side of the air handling unit is insufficient to ensure safe operation of the heating elements.

  • Page 96 MAINTENANCE 10.1 MAINTENANCE The basic technical data of the air handling unit, such as the type, parameters and dimensions of the most essential components (filters, heat exchangers, fans, electric motors), can be found in the technical data sheet that is supplied with each unit. All maintenance work on air handling units should be carried out with the unit switched off.
  • Page 97 If the throttle is dirty and does not operate freely, it should be cleaned according to one of the following methods: • using a hoover with a soft suction nozzle, • by blowing with compressed air, • washing with water and non-corrosive cleaning agents for aluminium. After re-installation, the damper should be carefully sealed, above all on the outside air intake side, to prevent the water heater from freezing.
  • Page 98 AIR FILTERS • Under standard operating conditions for air handling units, filters should be changed approximately twice a year. The need to change the filter (in addition to visually visible contamination) is also indicated by a drop in pressure: EU4 - 150Pa, EU5, EU7 - 200 Pa, EU9 - 300 Pa •...
  • Page 99 damage to some components or subassemblies (motor, bearings, plastic parts, etc.) installed in adjacent sections. ELECTRIC HEATER • The electric heater battery consists of bare heating coils. During operation of the air handling unit, when the heater is switched off, dust may settle on the heating coils. When the heater is restarted, heavy contamination of the surface of the heater can generate unpleasant burning dust odours, even leading to an initial fire hazard.
  • Page 100 washing the air ducts along their entire length with water and non-corrosive aluminium cleaning agents, In the case of very dirty exchangers, a pressurised water jet can be used to clean them. • When cleaning the exchanger with mechanical means, maximum care must be taken not to damage or deform the exchanger panels.
  • Page 101 • Cleaning should be carried out by vacuuming or wiping all surfaces with a wet cloth. For more serious soiling, nylon brushes can be used: the inside of the casing using a hoover, rotor with a hoover or by damp wiping with a cloth dampened in a soft cleaning agent. www.vtsgroup.com OIMM VENTUS COMPACT HP - ver.5.0.9 (10.2024)
