The ventilator is delivered packaged and can be transported on a pallet. Once unpacked
the ventilator should be handled carefully, especially the spigots etc. Deformation could
result in internal damage to the moving parts.
If there is not a lot of space to move the ventilator, the service door can be dismounted
as shown in section 1.1.
NB The ventilator must not be lifted using the service door handle.
Weight
1.3.1 Fitting indoors
There are various ways of fitting the
ventilator indoors (Fig. 2).
With methods B and D the service door
must be kept in the open position during
service. A safety fitting for this purpose can
be supplied (including an assembly kit).
If the ventilator is to run intermittently, there
is a risk of condensation in the motor.
Therefore, use mounting method A or B
only.
Service access Wherever the ventilator is fitted, there
should be space enough to be able to open
the service door to an angle of approx. 80°
and to access the locking screws.
Warning The motor must never be placed vertically under the cabinet and the
motor and EC control must never be covered or they will overheat.

outdoor use and can be used for
transport of air in the temperature range
up to 200°C. This version is also fitted
with a drain in installation method "A"
A and B fitting methods should be
used for outdoor fitting. Fitting
methods C and D require a specially
designed ventilator (Fig. 4) — contact
EXHAUSTO.
All exterior seams, including spigots
have been jointed to prevent water from
getting inside.
The cabinet is class C4 DS/EN ISO12
944.2 certified and designed for
outdoors.
Service access Wherever the ventilator is fitted, there should
be space enough to be able to open the
service door to an angle of approx. 80° and to
access the locking screws.
1.3.3 Fitting the mounting bars
• Mounting should be done on a stable vibration-resistant base, to minimise any
vibration that might be caused by the ventilator. A cement slab placed on a
wooden base construction is recommended.
• Fit the mounting bars on the cabinet with the supplied fitting screws. The cabinet
has holes already bored for fitting method A.
•BESB/FSB 400 and 500: When using fitting method B (Fig. 2/4) for BESB/FSB
400 and 500, holes (Ø16 - Ø20) are bored in the cabinet for the fitting of the

Earth leak circuit
breakers
If current earth leak circuit breakers are fitted in the installation, they must be of
a type that meets the following requirements:
• PFI type A breaker that breaks the circuit when a vagrant current with DC
content (pulsating DC) in accordance with EN 61008.
• The circuit breakers must be marked with the following symbol:
Requirements • Disconnection time of max 0.3 seconds
Dimensioning of
the neutral
conductor.
Multiple one-phase BESB/FSB with EC installations in a shared network with a common
neutral, require special dimensioning of the neutral, as the current is not a pure sine
wave.
Example For example if three EC motors are installed, sharing 3-phases, the neutral current is
the sum of the three motors’ current.
Existing
installations
If you are fitting motors to an existing installation, check that the neutral conductor can
cope with the resultant load.

Flexible
connections
The ventilator must always be connected to the duct system with FLF, to avoid any
chance of vibrations being transmitted. The spigots on the ventilator are standard-sized
and fitted with rubber seals.
To achieve maximum performance with minimal energy consumption the ventilator
should be connected to the duct system with the specified lengths of duct before and
after the ventilator. The FLF connections must always be fitted as shown.
Sound pressure
level
The ventilator is fitted with sound dampers suited to the requirements of the operating
area. The sound pressure for all types of BESB/FSB is less than 70 dB (A). The duct
system is insulated against sound propagation, heat loss, fire and condensation.
No Duct A protective net (accessory) with mesh size of 12 mm must be fitted if the ventilator is
not fitted to a duct. It should be noted that:
• such fittings result in a pressure drop in the system
• Air volume measurements cannot be measured correctly when there is no duct
fitted on the suction side
