Page 7: Connection Of Sections
Air Handling Unit Installation, Operation And Maintenance Instructions WARNING: Air handling units should be installed on a rigid and level surface. Correct alignment of the sections is essential to maintain a satisfactory airtight enclosure and to avoid distortion to the casing and components. -
Page 8: Connections
Air Handling Unit Installation, Operation And Maintenance Instructions WARNING: Do not use excessive forces to align the sections, because it may deform the aluminum framework and casing. Sections are locked together by special connection parts, bolts, and nuts. Section connection parts are mounted on the unit sections, bolts and nuts are fitted on the connection pieces. - Page 9 Air Handling Unit Installation, Operation And Maintenance Instructions 5.1.2- Ducted Outlet Conditions With the outlet connected to the discharge duct by a flexible connector, which is desirable for noise and vibration isolation, it is important that the connector is correctly fitted. The fan outlet and the duct should not be misaligned (Fig.6) nor should the flexible connector be allowed to concertina.
- Page 10 Air Handling Unit Installation, Operation And Maintenance Instructions Extremely high losses occur when attempts are made to change the direction of the airflow close to the fan discharge. If this is necessary the installation should be carried out as in (Fig.12) and ever as in (Fig.13) A better solution is to have a parallel section of ducting prior to changing direction and it should be as long as can be accommodated.

Page 11: Piping Connections
Air Handling Unit Installation, Operation And Maintenance Instructions 5.2- Piping Connections Coils should be piped in counter flow arrangement to achieve required capacity. This arrangement requires that the entering heating or cooling fluid contacts the air leaving the coil. Water heating and cooling coils should be arranged with inlet connection at the lowest level on one side of the coil near downstream and water outlet connection on the same side but at high level near the upstream. - Page 12 Air Handling Unit Installation, Operation And Maintenance Instructions www.doguhvac.com...

Page 13: Condensate Drain Lines
Air Handling Unit Installation, Operation And Maintenance Instructions 5.3- Condensate Drain Lines Moisture condensed out of the airstreams on cooling / dehumidifying coils should be drained out of the unit, to prevent water damage in the air handling unit and ductwork system. Following precautions should be observed in piping of condensate drain lines. - Page 14 Air Handling Unit Installation, Operation And Maintenance Instructions Starter for centrifugal fans in the air handling units for single speed motors driving through V-belts are normally of the direct-on-line type. However the customer or Electric Supply Authority may require motors above 3kW to be operated by a star-delta starter, to reduce starting current.
- Page 15 - If the operating point of the fan will exceed the design operating point of the fan, there is a risk of motor to overload and overheat. Please consult to DOGU IKLIMLENDIRME A.S., if the design operating point of the fan will be exceeded.
