• Wear the appropriate PPE (Personal Protective Equipment) before any work is carried out.
• Before installing the ventilation unit, make sure that the support and the location are strong enough
to support the weight of the unit and any accessories.
• Do not open the access panels without disconnecting the power supply at the lockable disconnect
switch on the unit.
• If work is to be done on the unit, turn o󰀨 the power at the main circuit breaker and make sure that no

Operating mode
COP mode: Constant pressure regulation
This operating mode allows to maintain a constant pressure in the network over the whole operating range
of the fan. The pressure losses in the network (opening/closing of dampers, dual ow vents...) modify the
pressure in the suction plenum of the ventilation box.
This pressure is measured by a sensor present in the VCHV control box.
This pressure measurement coupled with a regulation loop allows the VCHV to adapt the fan speed to
maintain a constant pressure in the network.
The pressure set point is adjustable from the control buttons of the VCHV control box.
The operation is fully automatic.
This mode of operation is programmed by default on the casing at the factory with a pressure set point of
140 Pa.

• A minimum air gap of 100 mm must be main-
tained between the unit and the horizontal sup-
porting structure.
• Horizontal discharge: unconditionally per-
mitted.
• Vertical discharge: allowed if connected to an
air duct system.
• The xing method of the unit must be dimen-
sioned in such a way as to ensure that it is held
securely in the event of a re.
3.5 Assembly of accessories
Circular discharge connection
Fix the at spigot with a gasket using 6 self-drilling screws (not supplied).
For a unit not connected to the discharge, add a Chinese Cap (CP) to allow a 360° exhaust air outlet
around the vertical axis of the discharge. According to the NF DTU 68.3 P 1-1-1, the CP allows to be free
from wind e󰀨ects and not to add 20 Pa of additional pressure drop.

4. AERAULIC CONNECTION
The unit must be xed on a at surface, through the holes on the xing brackets or on the omega provided
for this purpose. We recommend mounting on anti-vibration pads and connecting with exible sleeves.

5. ELECTRIC CONNECTION
5.1 Preliminary precautions
Models 30 to 92 :
This electronically commutated motor cannot be powered directly from the mains, otherwise it will be des-
troyed. The power supply must be provided by the controller. The unit must be switched on and o󰀨 via the
external Start/Stop control, type BCCA (wiring, see §"5.4 Electrical connection of the Start/Stop control",
page 16). Do not shut down the unit by directly disconnecting the power supply to the controller via the
INTZ or by a mains failure.
Switch o󰀨 and disconnect the power supply before working on the unit.
When working on the fan, the proximity switch dened according to IEC947-3/695-2-1 must be opened
and locked in this position (according to NF C 15-100).

7. MAINTENANCE
7.1 Preliminary precautions
Switch o󰀨 the power supply before any intervention and make sure that it cannot be restored by mistake
(+ lock the optional switch-disconnector in the OFF position during all handling).
Note:
For models 04 to 22: presence of an auxiliary fan to cool the motor when operating in "re mode".
In "re mode": when a re breaks out, the C4 unit automatically switches to its maximum rotation speed to ex-
tract the smoke. At this time, for unit sizes 04 to 22, an auxiliary fan will start up to cool the motorized fan of the
C4 unit.
A push button on the side of the unit allows to test the correct operation of the auxiliary fan.
7.2 Frequency of maintenance
Carry out a periodic inspection on the following indicative basis:
Organ At start-up Every 6 months minimum
Impeller Check the direction of rotation, check the absence of friction between the moving parts
and the xed parts
Clean if necessary, check that there is no
friction between the moving and xed parts
Controller Check the connections, especially the ground
connection Tighten terminals if necessary, check current rating
Switch Check the connections, especially the ground
connection Tighten the lugs if necessary
Duct networks Check for leaks Clean if necessary
Pressure tap Check the air connections Check the operation
Auxiliary fan Check the operation with the test button Check the operation with the test button
Auxiliary fan (JBRB ECOWATT®PR VCHV 04/06/10 and 22 only).

7.4 Replacement of the motor fan
7.4.1 JBRB ECOWATT®VCHV PR 04 to 22
• Turn o󰀨 the power supply.
• Unscrew the 2 screws of the door, then remove the door.
• Disconnect the power cable from the switch.
• Unlock the 4 toggles, then remove the top of the unit using the handles.
• Disconnect the 2 quick connectors behind the command support.
• Unscrew the screw inside the command part, then remove the compartment.
• Unscrew the 4 screws of the motor turbine assembly, then remove the motor turbine assembly.
• Put in position the new motor turbine assembly on the 2 lugs.
• Screw the 4 screws M8x20 without tightening them.
• Screw the 2 M8x80 screws into the motor support, and adjust the wheelhouse clearance by
screwing or unscrewing these screws.
• Tighten the 4 M8x20 screws, then remove the 2 M8x80 screws.
• Reassemble the command compartment, reconnect the 3 quick connectors, and replace the
screw at the bottom of the compartment.
• Make sure that the assembly turns freely (fan wheel) and that there is no object likely to be thrown
by the turbine.
