This range of Cased Axial Jet Fans has been
manufactured to the rigorous standards of production
and quality control in accordance with the International
Quality Standards ISO 9001. All components have been
checked and tested at the end of the manufacturing
process.
All appliances are supplied in perfect condition and
operation. We recommend that you check the following
when receiving this product:
1.
That it is the correct size.
2.
That it is the correct model type.
3.
The details on the rating label are those required:
voltage, frequency...
All Jet Fans should be installed in accordance with all
applicable National and Local standards for smoke
extract ventilation systems.
Installation.
- When installing the Jet Fan, for optimum operation ensure
there are no obstructions to restrict / obstruct inlet /
outlet airflow.
- Before connecting the unit to the electrical supply, ensure
that the impeller turns freely and there are no obstructions
to the airflow.
- Before finalizing the installation ensure that there is no open
access to any moving parts and check that the system
complies with all standards concerning the safety of rotating
electrical machines.
Electrical Connection
- Before starting any installation or wiring of the Jet Fan
range, ensure that the mains electrical supply is
disconnected.
- Before making any electrical connections ensure that the
Voltage and Frequency of the mains electrical supply
matches that of the fan data plate label (maximum
permissible deviation of voltage and frequency +/- 5%).
- TJHT, TJHU Jet Fans are fitted with motors capable of
working at emergency High Temperatures for periods of
time:
F200
200ºC / 120 mins
F300
300ºC / 120 mins
F400
400ºC / 120 mins
Motor connection to electrical supply should be with
suitable rated cable. Example: OMERIN type MA-VAS or
equivalent in accordance with Standard UNE 20431
(CEI-331).
- Before installation ensure that the electrical cable
selected is rated (in accordance with all appreciable
standards) to withstand the maximum absorbed
current of the fan.
JETFANS
-
Where motors are equipped with accessories:

-
Check that the fan earth connection is correctly
wired to a suitable grounding point.
Impeller.
-
All impellers are manufactured from high grade die
cast aluminium.
-
Do Not alter or modify the angle of the blades. Any
unauthorized alteration to the impeller blade angle
could have dangerous implications to the intended
operation of the fan. Any alteration to the product by
any means will invalidate the S&P guarantee.
Operating Conditions.
-
The range of Jet Fans has been designed to
withstand one off emergency exposure to the
stated High Temperature / time duration, on the
Jetfan:
F200 200ºC / 120 mins
F300 300ºC / 120 mins
F400 400ªC / 120 mins.
The range has been tested and independently
certified by the Applus laboratory under the EN
12101-3/2002 Standards.
-
The product range is designed to operate in the
case
of
a
fire
recommended that the fan is checked at least every
six (6) months for electrical and mechanical
operation.
-
Each time the fan is checked, ensure that the
impeller rotates in the correct direction as indicated
by the arrow on the fan casing.
Maintenance.
-
Before conducting any maintenance or cleaning of
the fan ensure that the unit is disconnected from
the mains electrical supply.
-
Fans for emergency High Temperature smoke
operation may provide a critical life saving function and
thus should be inspected and maintained under a
