This range of Cased Axial Jet Fans has been manu-
factured to the rigorous standards of production and
quality control in accordance with the International
Quality Standards. All components have been chec-
ked and tested at the end of the manufacturing pro-
cess.
All appliances are supplied in perfect condition and
operation. We recommend that you check the fo-
llowing when receiving this product:
1. That it is the correct model and size.
2. 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 / obs-
truct inlet / outlet airfl ow.
• Before connecting the unit to the electrical supply,
ensure that the impeller turns freely.
• Before fi nalizing the installation ensure that there
is no open access to any moving parts and check
that the system complies with all standards con-
cerning 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 elec-
trical supply matches that of the fan data plate la-
bel (maximum permissible deviation of voltage and
frequency +/- 5%).
• TJHT, TJHU Jet Fans are fi tted 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 appre-
ciable standards) to withstand the maximum ab-
sorbed current of the fan.
• Where motors are equipped with accessories:
thermal protection, space heaters, speed control
device, these must be disabled during operation in
smoke extraction mode.
• All Jet Fans models should be wired to the electri-
cal supply in accordance with diagram provided in
connection box.
• Check that the fan earth connection is correctly wi-
red to a suitable grounding point.
IMPELLER
• All impellers are manufactured from high grade
die cast aluminium.
• Manipulation by any means of the impeller or mo-
tor may result in inmbalance and damage to motor.
• Any alteration to the product by any means will in-
validate the S&P guarantee.
OPERATING CONDITIONS
• The range of Jet Fans has been designed to wi-
thstand 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 certi-
fi ed by the Applus laboratory under the EN 12101-3
Standards.
• It is 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 im-
peller 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 un-
der a verifi able maintenance system in accordance
with these instructions. We recommend Jet Fan
is inspected and cleaned regularly to ensure safe
operation.
