Units are suitable for external or internal use. When moving
the unit, handle with care and in such a manner as to limit
damaging the external finish as this may reduce the ability to
resist corrosion. Units are to be rigged and lifted using
spreaders, taking into account the weight of the unit, and lifting
gear should be arranged so as not to bear on the casework.

This manual must be read in full before Installation, Operation
and Maintenance of the units supplied

IMPORTANT
!
Only experienced fitters should undertake this work.
The WORKHORSE is a range of utility extract fan units, with a
duty range of between 0.5 and 11m³/s.
The unit offers a reliable solution to arduous environments,
complete with a drive/weather guard and fitted isolator. The
standard operating temperature of the unit is -20 to +35°C.
For further technical details contact VES on 08702 404340
quoting the sales order (SO) number and the unit type as found
on the unit nameplate.

Installation
The entire system must be considered for safety purposes and
it is the responsibility of the installer to ensure that all of the
equipment is installed in compliance with the manufacturer’s
recommendations, with due regard to the current HEALTH
AND SAFETY AT WORK ACT and conforms to all relevant
statutory regulations.
Where a unit is installed so that a failure of components could
result in injury to personnel, precautions should be taken to
prevent such an injury.
Reciept of Goods/Handling
Immediately upon receipt of goods, check for possible damage
in transit, paying particular attention to fan impeller, motor and
flexible connections. Prior to installation please check to ensure
smooth rotation of the impeller after transit. Also check to ensure
that any ancillary items are included. These will normally be
supplied fitted or taped to the unit (in the case of small items).!
In the event of any damage having occurred or if any item
found to be missing, it is essential to inform VES Andover Ltd.
within 3 working days of delivery quoting sales order number
and the unit type as found on the unit nameplate. After this
period we will be unable to accept any claim for damaged or
missing goods.
It is the installer’s responsibility to ensure that access panels
are not obstructed in any way and safe working access for
maintenance must be provided.
For optimum unit performance, careful consideration must be
paid to the location of the unit in relation to the ductwork and
associated items; placing the unit directly adjacent to a bend
in ductwork will impede airflow and reduce performance.
Should the system require the unit to work in free air, guards
should be fitted to the exposed inlet/outlet opening.

WORKHORSE Centrifugal fans
Installation, Operation and maintenance Manual
Consideration must also be given by the installer for adequate
illumination of the unit location in order for safe maintenance.
The force required to deflect the belt should be from 0.5 to 0.8
kg. After the unit has been positioned, re-check that the impeller
is smooth running as this may have moved during transit.
Where provided, flanges and spigots should not be used to
support the ductwork and used solely as a means of ductwork
connection.
For internal / plant room applications, where extra ventilation
may be required, remove the weather lid as per fig.4. This will
assist in the thermal stability of the motor.
Each unit is fitted with a Ø22mm drain connection to the lowest
point of the fan scroll (omitted on those units where the outlet
is facing down). If this connection is redundant ensure that the
drain plug is fitted.
IMPORTANT
!
Consideration should be given to the units location, this is
especially important with external mounting as the wind and
elements may affect the overall stability of the unit. Secure
unit in place as appropriate.

Set-up
Motor and electrical details must be checked prior to connection
to mains supply. All motor information can be found on the unit
data sheet, supplied attached to the unit.

!
IMPORTANT
Electrical Supply must be fully isolated before attempting to affect any work on this unit
Ensure correct pulley alignment as indicated in fig.2.
To check the tension of the drive belt apply a force
perpendicular to the centre of the belt span sufficient to deflect
the belt 16mm for every metre of span length as indicated in
fig.3.
WORKHORSE units comprise a single inlet backward curve
fan powered by a belt-driven drive assembly, terminated to a
local isolator.
All electrical connections to any unit must be carried out in
accordance with the current edition of the
I.E.E REGULATIONS and only competent Electricians should
be allowed to affect any electrical work to our units.
IMPORTANT
!
Do not connect any unit to an electrical supply voltage outside
of that indicated on the motor nameplate
Mains cables should be suitably sized as per details found on
the unit nameplate, see fig.5 & 6 for guidance and terminated
as shown on the appropriate wiring diagram see fig.7. Note: 2
speed motors are dual wound
WARNING
!
When used in conjunction with an Inverter for speed control a
minimum of 5 minutes should be given to allow the capacitors
to discharge before commencing any work

Maintenance
IMPORTANT
!
Before attempting to carry out any work on our units, the unit
MUST BE COMPLETELY ISOLATED from its electrical supply.
Ensure a minimum of two minutes after electrical disconnection
before removing access panels - this will allow any moving
parts to come to a rest.
In general, this series of units require little maintenance. In
the unlikely event of component failure, spares are available
from stock at VES Andover Ltd.
IMPORTANT
!
Before attempting to carry out any maintenance work or repair
work on our units, all accompanying documentation including
warning labels on the unit must be referenced.
Recommended checks
To keep the unit in good running order, the following
maintenance routine is recommended.
Three Monthly Check
•The belt drive should be thoroughly checked. Belts are subject
to fatigue and will stretch over a period of time. Within normal
operating conditions, belts tend to stretch in the first few days
of running which should be taken into consideration when
commissioning the unit. Inspection of belts at this early stage
is advised. After this initial period, regular 3 monthly checks
should be made. If belts are found to be loose or worn retighten
by slackening bolts and slide the motor plate down, retighten
the bolts. Refer to fig.3 for the recommended tension. Replace
the belts if necessary.
Do not mix belts. If two or more belts are used make sure that
all are replaced at the same time. Excess wear on the side of
belts indicates misalignment of the pulleys and should be
rectified at once see fig.2.
•A check for excessive noise or vibration should be carried out.
This will help to identify fan and motor defects at an early stage.
The cause of excessive noise and vibration could be due to:
loose connections, mis-aligned fan belts, unbalanced fans or
worn bearings.
WEEE Directive
At the end of their useful life the packaging and product
should be disposed of via a suitable recycling centre.
Do not dispose of with normal household waste.
Do not burn.
!
IMPORTANT
Lubricate the bearings via the grease nipple, with grease
suitable for high temperature applications.
When enquiring after or ordering spares contact VES
Customer Services Department, quoting the sales order
(SO) number and unit type as found on the unit nameplate.
Six Monthly Check
Telephone
Fax
Check for grease build-up in the system, especially around
the impeller. Remove the grease residue if necessary. Failure
to do this periodically could lead to a loss of performance or
cause the fan to become out of balance, ultimately leading to
bearing failure. If the drain connection is used ensure that this
is also free of any contaminants.

PLEASE ENSURE THAT THIS DOCUMENT IS
PASSED ON TO THE END USER.
It is recommended that for external units, particularly where
adverse environmental conditions prevail, all painted surfaces
be checked for signs of deterioration. Repaint as necessary;
paint can be supplied upon request.
Check for missing fixings which can go missing during
maintenance. Missing fixings should be replaced to maintain
the integrity of the unit.
