    GENERAL INFORMATION Thorough familiarization with the contents of this manual, as well as the installation, commissioning and operation of the air handling unit according to the instructions given and with observance of all health and safety regulations will guarantee a solid basis for efficient, safe and trouble-free operation of the unit. This document does not cover all possible configurations of these devices, does not give all examples of their assembly and installation, nor does it discuss all aspects of their commissioning, operation, repair and maintenance.
  • Page 6 Suspended air handling units (AHUs) VENTUS are designed for indoor installation. The design of these units is adapted to their suspension from the ceiling. The low height of the unit makes the air handling units fit perfectly in standard inter-ceiling spaces or spaces above the suspended ceiling. VENTUS VVS005s-VVS030s air handling units are designed to work with air duct systems supplying and extracting air from rooms according to the ventilation design.

  • Page 30: Electric Heater

    ELECTRIC HEATER 5.1 GENERAL INFORMATION The electric heater consists of heating elements (heaters), connection terminal, control CONTROL (SCCR) and protection against excessive temperature rise. The heaters are Cr-Ni-Fe heating wires of 6kW/400V. They are connected in heating slices (heating sections). The heater can consist of 3 heating slices. The housing of the heater is galvanized sheet metal without thermal insulation (ventilation duct).

  • Page 31: Electrical Installation Details

    Modulating the Supply Voltage Depending on the Heating Power Demand (First Heating Slice). The first slice is controlled smoothly 0-10V, each other (ON/OFF) ON-OFF. Each time the regulated slice reaches full power, the demand is transferred to the next slice, which starts operating at full capacity.

  • Page 32: Heater Power Supply Connection And Current Protection

    5.2 HEATER POWER SUPPLY CONNECTION AND CURRENT PROTECTION The power connection must be made using a separate switchboard, which is not supplied with the VTS delivery. The connection of the heater should be made in such a way that it is not possible for the heater to switch on when the fan is not on - for this purpose there are factory-mounted, serially connected protections in the form of a thermostat and pressure switch, preventing the heater from switching on if the temperature and airflow conditions are not met.

  • Page 36: Thermal Switch (Thermic)

    5.3 THERMAL SWITCH (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 °C. fter an emergency shutdown, the heater automatically turns on when the air temperature drops by 0°C.

  • Page 37: Differential Pressure Switch

    5.4 DIFFERENTIAL PRESSURE SWITCH The differential pressure switch is another safety element, in addition to the thermostat, that prevents the heater from operating in prohibited conditions. It prevents the heater from switching on when 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.

    ELECTRIC HEATER • The electric heater battery consists of bare heating coils. During operation of the air conditioning unit, when the heater is turned off, dust may settle on the heating coils. When the heater is restarted, heavy contamination of its surface can generate unpleasant odors of burning dust, even leading to an initial fire hazard.

The accumulation of dirt on plate heat exchangers is often limited to the first 50 mm in the exchanger. Before cleaning, adjacent sections of the air conditioning unit should be protected from contamination.
