3. Description of the air handling units – 8 models

3.1 Common for all air handling unit models

All Danvent DV and TIME air handling units are manufactured in compliance with the EC Declaration of Conformity and they are CE marked as machines. If the buyer carries out changes or adds components in or on the machine, the buyer must issue a new EC Declaration of Conformity and a new CE marking of the machine. The buyer must issue a new EC Declaration of Conformity and a new CE marking of the machine, when a unit is delivered without control system and the control system is installed in the unit on the site. To promote correct use of the machines, the below-mentioned instructions are an integral part of the machine:

• Transport and Installation Manual – printed on paper and delivered with the unit

• User Manual - printed on paper and delivered with the unit

• Transport and Installation Manual, User Manual, Operator’s Guide, Commissioning protocol ,

Maintenance, Dismantling and Disposal Manual, Data sheets about components in the control system – all on a CD delivered with the unit

3.2 Specific data about each model of the air handling unit – 8 models

3.2.1 DV unit without switchboard/control system

DV unit without switchboard/control system is a unit without an intelligent controller and without components for the control of functions. This model is, however, usually delivered with some electric components - for example fan motors, motor for turning the rotary heat exchanger as well as the internal control system for revolutions per minute of the rotor. The common rule for this model is that no components are connected to an intelligent controller. The machine is CE marked, and installation of control system and other changes of the machine have the consequence that the buyer must issue a new EC Declaration of Conformity and a new CE marking of the machine.

3.2.2 TIME unit – indoor model

The indoor model of TIME has an integrated control system and the switchboard mounted on the unit. The switchboard is always mounted on the unit section with the supply air fan. The intelligent controller Systemair E28 – is mounted in the switchboard, and all electrical connections between switchboard and components in the unit are installed. The control system is configured according to the customer’s order – confirmed by the order confirmation - to promote easy start-up on the site. The unit is tested at the factory and all functions are confirmed by a final functional test and test report. After the final test the unit is divided into at least 2 and for larger units up to 6 sections to facilitate the transport. After reassembly of the unit on the site, the clearly marked cables must be reconnected in the marked switchboard terminals. Furthermore all external components must be connected on the site.

3.2.2.1 External components

terminals are present in the switchboard for valve motors and circulation pump, but cables are not installed and not connected to terminals in the switchboard. The Systemair Control Panel with 10 metres of cable is not connected to the controller in the switchboard. All external components delivered are packed in a cardboard box delivered together with the unit.

3.2.3 TIME unit – outdoor model

The outdoor model of TIME has an integrated control system and the switchboard mounted inside the unit. The switchboard is always mounted in the unit section with the heat exchanger and the switchboard is always placed at the warm side of the heat exchanger. The intelligent controller - Systemair E28 – is mounted in the switchboard, and all electrical connections between switchboard and components in the unit are installed. The control system is configured according to the customer order – confirmed by the order confirmation to promote easy start-up on the site. The unit is tested at the factory and all functions are confirmed by a final functional test and test report. The unit is delivered as one assembled section on base frame. All external components must be connected on the site.

3.2.3.1 External components

External components are Systemair Control Panel, valves, valve motors, pressure transmitters, supply air temperature sensor, sensor for water temperature in the heating coil (if water heating coil was requested) and circulation pump (Systemair does not deliver the pump). Supply air temperature sensor and sensor for water temperature in the heating coil are cabled to the terminals in the switchboard. Terminals are present in the switchboard for pressure transmitters, if it is a solution for constant pressure in the ducts, and terminals are present in the switchboard for valve motors and circulation pump, but cables are not installed and not connected to terminals in the switchboard. The Systemair Control Panel with 10 meters of cable is not connected to the controller in the switchboard. All external components delivered are packed in a cardboard box delivered together with the unit.

3.2.4 DV unit with switchboard/control system – delivered in several sections

This model of the DV unit has an integrated control system and depending on the size of the unit, the switchboard is installed on the unit or on the front of the unit. The intelligent controller - Systemair E28 – is mounted in the switchboard, and all electrical connections between switchboard and components in the unit are installed. The control system is configured according to the customer’s order – confirmed by the order confirmation - to promote easy start-up on the site. The unit is tested at the factory and all functions are confirmed by a final functional test and test report. After the final test the unit is divided in sections to facilitate the transport. After reassembly of the unit on the site, the clearly marked cables with sockets must be reconnected in the marked switchboard terminals. Cable strips are preinstalled in glue plinths for installation of the cables between the components in the unit-sections and the switchboard. Cables installed on the unit-sections in the pre-installed strips in glue plinths are protected by metal covers. The covers have been removed before installation of the cables and must be replaced after installation of the cables. Mains power supply must be installed directly in the marked circuit breakers for fan motor frequency converters and DVU (section with cooling compressor). All external components must be connected on the site.
