ENGLISH
II.3 Positioning
The system must be suspended above or supported on a sufficiently rigid surface (use a vibration damping mounts if
necessary). For ductwork connections, select duct sections to suit the dimensions of the flexible hoses, which should be
properly tensioned. The ducts should be insulated and the first accessories should be installed at a distance of 2.5 times
the duct diameter from the unit (T junction, etc.). Install the unit in such a way that internal components cannot be
damaged by bad weather or ambient temperature either during the installation or subsequent use of the unit.
Install a siphon on each condensate drain pipe. A siphon must not be used for more than one
condensate drain pipe. Caution: the siphons must be connected in the correct manner in order to
ensure that the condensate can drain freely.
The value H must correspond (in mm) to at least the maximum internal negative pressure of the
system x 1.
Example: p = 500 Pa = 50 mm CE
H > 50 mm 2H > 100 mm
Installation of systems in ceilings : units can be suspended on threaded rods. They can also be supported on a frames
attached to the structure of the building, provided that the frames have sufficient load capacity (frames to supplied by the
installer).
III GENERAL OPERATION
III.1 GENERAL
The VORT NRG EC EC/EH 600-2500 range consists of a programme of dual-flow systems with self-regulating energy
recovery, with high efficiency and high performance, designed for the service sectors and industrial installations.
Performance exceeds 90%.
VORT NRG EC (BASIC VERSION): Management of fans by potentiometer and bypass. Cannot be used with coils.
VORT NRG EC FIRST : Econological management of fans and the bypass. Allows management of a non-integrated coil
changeover (or a hot water coil and/or a cold water coil non-integrated) or an electrical non-integrated heater battery. On
request, it can be adapted for use with a non-integrated electrical heater battery and a non-integrated cold water coil.
VORT NRG EC PREMIUM BC : Econological management of fans and the bypass. Integral changeover coil.
VORT NRG EC PREMIUM BE : Econological management of fans and the bypass. Integral electrical heater battery and
provision for the addition of an extra non-integrated cold water coil.
VORT NRG EC INFINITE BC : Econological management of fans and the bypass. Integral changeover coil and integral
defrost coil.
VORT NRG EC INFINITE BE : Econological management of fans and the bypass. Integral electrical heater battery and
integral defrost coil and provision for the addition of an extra non-integrated cold water coil.
VORT NRG EC EH : Econological management of fans and the bypass. Integral defrost heater battery and provision for
the addition of one non-integrated changeover coil or (one non-integrated hot water and/or one non-integrated cold water
coil).
III.2 OPERATING SEQUENCE
Except VORT ENERGY EC versions
Start-up sequence :
• The recovery fan or VAR pressure monitoring mode starts at the same moment the fresh air damper is operated.
• The blower fan or VAR pressure monitoring mode starts at the same moment the recovery air damper is operated.
• Temperature control starts in accordance with the configured control mode. Electrical heating (if configured) starts on
the flow controller only (flow reversal). Pumps that have not yet been activated will start up.
• The alarm management function is activated after the pre-set time period. At this point the system is operating in
normal mode.
Conditions for startup :
The system starts up when one of the following conditions is met :
• The programmed schedule (timer) for normal speed or low speed operation is on "Run".
• The system is started manually from the CORRIGO controller.
• One of the digital inputs for forced run is activated.
