ensure minimum vibration and
noise transmission to surrounding
ductwork and building frames.
Antivibration mountings and
sound attenuating accessories
are available. Please contact
your local distributor.
- The fan should always be
installed so that safe operation
and maintenance can be ensured.
- Before installing the unit
ensure the impeller is running
freely and there are no
obstructions to the airflow.
ELECTRICAL CONNECTION
- Before Installation and Wiring
ENSURE THE MAINS
ELECTRICAL SUPPLY IS
DISCONNECTED!
- The electrical installation must
include a double pole switch
with a contact clearance of at
least 3 mm, correctly sized
and in accordance with the
electrical standards of the
country of installation.
- Ensure that the voltage and
frequency of the electrical
supply match the information
stated on the Data Plate of the
unit (maximum recommended
tolerance of Voltage (V) and
Frequency (Hz) ± 5%).
- The standard fans are fitted
with single-phase 2-speed
motor. All motors are also
100% speed controllable via
electronic voltage regulating
speed controllers.
Wiring diagram of the two
motors together:
- Connection to a change over
switch for two speeds operation fig.3.
- Connection to a speed controller
fig.4.
Wiring diagram of the two motors
separately:
Very important: if the operation of
only one motor is required, it will be
the one fitted at the inlet side of the
unit; otherwise the efficiency of the
unit would be impaired.
- Connection to a change over
switch for two speeds operation
fig.5.
- Connection to a speed controller
fig.6.
- Check that all models wich so
require are properly earthed.
- Before operation, check all
connections are correct and
there are no obstructions to the
airflow.
- On connecting the electrical
supply ensure the direction of
rotation and airflow correspond
with the direction of airflow / rotation
arrows (sited on unit).
MAINTENANCE
- Before inspection or repair, ensure
that the unit is disconnected from
the mains electrical supply.
- The fan impeller should be cleaned
at least once (1) a year to ensure
trouble free operation.
- Do not clean the unit with strong
detergents or cleaning fluids. Use
a damp (not wet) cloth only for
cleaning.
