Installing the units on the ceiling:
the units must be mounted preferably on a frame suspended from the structure of the
building, taking care to comply with load limits (the frame is the installer’s responsibility).
For these units,
provide a gradient of 2 to 3%
for the removal of condensate in the direction of the width. (connect the
condensate drainpipes as per section II.4). The 3000 model can be suspended directly from the ceiling by means
of M8 threaded rods connected to the attachment lugs on the lower part of the unit.
Before starting the unit, check the tightness of all bolts, particularly those of rotating components
II.4 Siphon
Provide a siphon on each condensate drainpipe. Each siphon can be used for one drainage system only. Note: the siphon
must be connected in accordance with best practices in order that condensate is removed as
efficiently as possible.
The height H must be at least equal to the maximum internal negative pressure of the unit (p in mm).
Example:
D
p = 500 Pa
50 mm CE
_
H > 50 mm 2H > 100 mm
III COMPOSITION AND OPERATION
III.1 General
The VORT NRG EC
(BASIC VERSION) models are high-efficiency heat recovery units equipped with advanced regulation
systems designed for offices and industrial installations. Their heat-exchange efficiency is greater than 90%. The standard
models are complemented by the versions summarised below:
VORT NRG EC FIRST:
manage a non-integrated changeover coil (hot water or cold water) or a non-integrated electric
coil.
VORT NRG EC PREMIUM BC:
include a hot water coil and manage an additional non-integrated cold water coil.
VORT NRG EC PREMIUM BE:
include an electric coil and manage an additional non-integrated cold water coil.
VORT NRG EC INFINITE BC:
include a hot water coil and a defrost coil, and manage an additional non-integrated cold
water coil.
VORT NRG EC INFINITE BE:
include an electric coil and a defrost coil, and also manage an additional non-integrated
cold water coil.
VORT NRG EC EH:
include a defrost coil, and manage a non-integrated changeover coil or a non-integrated hot water
coil and/or a non-integrated cold water coil.
