Part Number Coding
The T-Line is a range of direct drive duct mounted extract fans, designed typically for
arduous condions i.e hot air with high grease content. The standard ambient operang
temperature of the unit is -20 to +35°C, with in-duct airflow temperature up to 120°C.

Immediately upon receipt of goods, check for possible damage in transit. Also check to
ensure that any ancillary items are included. These will be supplied fied or taped to the
unit (in the case of small items). In the event of any damage having occurred or if any item
is found to be missing, it is essenal to inform VES Andover Ltd. within 3 working days of
delivery, quong the sale s order (SO) number, and the unit type as found on the unit
nameplate. Aer this period VES Andover Ltd. will be unable to accept any claim for
damaged or missing goods.
Receipt of Goods
When moving the unit, handle with care and in such a manner liming damage to the
casework. Parcular care must be taken when moving weatherproof units, any damage to
the external powder coat finish may reduce the ability to resist corrosion. Units are to be
rigged and lied using spreaders, taking into account the weight of the unit, liing gear
should be arranged so as not to bear on the casework.
Installaon
Safety for the enre system must be considered when installing the unit and it is the
responsibility of the installer to ensure that all of the equipment is installed in
compliance with the manufacturer’s recommendaons, with due r egard to the current
HEALTH AND SAFETY AT WORK ACT and conform to all relevant statutory regulaons.
Precauons should be in place so that in the unlikely event of component failure the risk of
personnel injury is reduced. For opmum unit performance, careful consideraon must be
paid to the locaon of the unit in relaon to the ductwork and associated items; i.e placing
the unit directly adjacent to a bend in the ductwork will impede airflow and reduce
performance.

The T-Line unit is de signed to be mounted in a range of orientaons. The unit can be
suspended from the cei ling using drop-rods, or bolted to the plant room floor. It is the
installer’s responsibility to ensure that there is sa fe working access provided to the unit f or
maintenance. The ins taller must also c onsider, adequate illuminaon of the unit, in order
for safe maintenance to be carried out .

Installaon
Units should only be supported using the support feet as provided by VES Andover Ltd.
with the unit. Contact VES Andover Ltd. before aempng to support the unit using
alternave methods. Only experienced engineers should undertake this work.
Take necessary safety precauons when w orking in ele vated posions.
Cauon
The electrical supply must be fully isolated before aempng to complete any work on
this unit. All electrical connecons to any unit must be carried out in accordance with
the current edion of the I.E.T Regulaons and only competent electricians should be
allowed to carry out any electrical work to our units.

On weatherproof units the motor must be guarded, this is done by rotang the motor guard
to the correct orientaon. (Meshed edges facing the ground).

Before aempng to carry out any maintenance work, invesgave work, or repair work
on our units, the unit MUST BE COMPLETELY ISOLATED from its electrical supply. Ensure a
minimum of two minutes aer electrical disconnecon before removing access panels.
Warning
Before aempng to carry out any work on our units, all accompanying documentaon
including warning labels on the unit must be referenced.
Should it be necessary to remove any component ensure that these are secured into
posion once reinstalled. It is crical that aer any maintenance work has been
conducted that all components removed/replaced are refied correctly by a competent
engineer.
When accessing the unit always use the handles to ensure the access panels are
handled/opened in a controlled manner so as to avoid damage to the unit or injury to
personnel. This is parcularly important with boom access units.
Cauon
Remove the access panels and loosen the bolts holding the inlet eye in place. Align the
inlet eye and impeller ensuring the inlet eye is central to the impellor and make sure gap
‘A’ is constant. Hand ghten the bolts and rotate the impellor to ensure the it runs
smoothly, secure into posion b y ghtening the retaining bolts.
A
Ensure that the clearance gap “A” between fan and inlet eye is constant. Misalignment
may cause undue wear on the impeller and inlet eye.
Always make sure the fan is rotang in the
correct direcon (an-clockwise when viewed
from the motor). Direcon of airflow is
indicated on the unit.
Impeller/Inlet Eye
Alignment
The impeller should r otate freely, this posion is f actory set. In the unli kely event of
movement during transit realign the impellor with the inlet eye.

Before starng the unit ensure the following set-up procedures are completed. Work to
be carried out by a competent engineer.

This differenal pressure compares the stac pressure in front of the fan inlet ring with the
stac pressure in the inlet ring of the narrowest point. The differenal pressure between
the stac pressures is related to the air volume via the energy conservaon rate as per the
graph below. Simply read across from the pressure measurement to the appropriate fan
curve and down to calculate the resultant air volume.
Measured differenal pressure: 1400Pa - Unit: TLL400

Spares & Repairs
The fan impeller should be cleaned every 6 months. Failure to clean the fan on a regular
basis could result in loss of fan performance, or cause it to fall out of balance. If a fan is
staonary for long periods in a humid atmosphere, it should be switched ON for minimum
of two hours every month to remove any moisture that may have condensed within the
motor.
T-Line units are supplied in both unp ainted and po wder coat painted galvanised sheet
