JBRB ECOWATT®04 to 38 can be installed with the
cover facing downwards.
• Air space of at least 100mm must be main-
tained between the unit and the horizontal sur-
face on which it is set up.
• Horizontal discharge: unconditionally author-
ised.
• Vertical discharge: authorised if connected to
an aeraulic network.
• The unit fastening mode must be su󰀩cient to
ensure it is held well in place in case of re.
3.5 Accessories assembly
3.5.1 Circular connection to discharge
Fasten the sealed at bracket using 6 self-drilling screws (not supplied).
For a unit not connected to discharge, add a vent cowl (CP) to enable 360° exhaust air outlet around
the vertical discharge axis. According to the NF DTU 68.3 P 1-1-1 standard, the CP makes it possible to
eliminate the e󰀨ects of the wind and not add 20Pa of additional pressure drop.

13/28 NT00000704-JBRB-ECOWATT-AN-210301
4. AERAULIC CONNECTION
The unit must be fastened to a very at surface, using the holes drilled in the mounting feet or the omega
bars provided for this purpose. Installation on anti-vibration supports and connection with exible connec-
tors are recommended.

5. ELECTRICAL CONNECTION
5.1 Prior precautions
Models 30 to 92:
This electronic-switching motor cannot be powered directly by mains power, on pain of destruction. Its
power must be supplied by the controller.
The device must be turned on and o󰀨 via the factory-wired REB ECOWATT®on the controller’s Start/Stop
terminals. Do not turn o󰀨 the device by directly shutting o󰀨 the controller’s power supply via the INTZ or
shutting o󰀨 the mains power supply.
Short circuit protection
The JBRB ECOWATT®power supply must have a short circuit protection. The short circuit protection
equipment must at least have a "C" curve trigger according to IEC 60898-1.
