ERGOVENT diffusers’ installation instructions

ERGOVENT diffusers can help hide air conditioning systems when used with Fan-coil units. The windspeeds are lower, making the A/C quieter and air is distributed more evenly across the room when RONDO models are placed in different corners of the room.

ERGOVENT diffusers can be successfully connected to any standard duct system with 100 mm, 125 mm, 150 mm or 160 mm diameter. If steel ducts are used, the diffuser can be connected directly to the duct or via a flexible connection. If a flexible 75 mm plastic duct system is used, the diffuser is connected via a standard plenum box or special ERGOVENT plenum box.

POSSIBLE DIFFUSER CONNECTIONS AND CORRESPONDING INSTALLATION METHODS

OPTION 1:

CONNECTION: via a flexible corugated pipe
AIR DUCT SYSTEM: metal ducts

OPTION 2:

CONNECTION: via a plenum box (metal/plastic)
CEILING CONDITION: plasterboards are not attached
AIR DUCT SYSTEM: 75 mm plastic ducts

OPTION 3:

CONNECTION: via a plenum box (metal/plastic pipe)
CEILING CONDITION: plasterboards are attached
AIR DUCT SYSTEM: 75 mm plastic ducts

DIMENSIONS REQUIRED FOR A SUCCESSFUL INSTALLATION

INSTALLATION METHODS
Here we will show all possible diffuser connection situations.

OPTION 1
DIRECT CONNECTION TO A STEEL DUCT

OPTION 2
VIA A FLEXIBLE CORRUGATED PIPE (steel duct system)

Diffusers can be connected to steel ducts also via a corrugated flexible duct. This is a very simple way.

OPTION 3
CONNECTION THROUGH A DIFFUSER BOX BEFORE THE PLASTERBOARDS ARE ATTACHED

If flexible plastic ducts (75 mm diameter) are used for the ventilation system, the diffusers are connected via a plenum box.

See the detailed installation instructions for a full description

OPTION 4
INSTALLATION AFTER THE PLASTERBOARDS HAVE BEEN ATTACHED

If the ceiling plasterboard is already installed and ventilation ducts are cut flush with the surface of the gypsum ceiling, Ergovent diffuser is installed this way:

AIR FLOW REGULATION

The diffuser cover must always be level with the ceiling. Each diffuser comes with a convenient ERGOVENT balancing valve. If there is a need to additionally regulate the air flow, we recommend using these dampers.

ERGOVENT LINEO PRO is intended for mechanical ventilation systems. Diffusers have an air flow balancing velve. Aerodynamic air valve is inside the diffuser and can be conveniently controled from the outside.
