Installation, Operation and Maintenance Manual

Immediately upon receipt of goods, check for possible damage in transit paying particular
attention to fan impellers, coil connections and unit casing. Prior to installation please check
to ensure alignment and smooth rotation of the impeller after transit. Also check to ensure
that any ancillary items are included. These will normally be supplied fi tted or, in the case of
small items, taped to the unit.
In the event of any damage having occurred or if any item is found to be missing, it is
essential to inform VES Andover Ltd. within
7 days
of delivery quoting sales order number
and the unit type, as found on the unit nameplate.
After this period, VES would be unable to accept any claim for damaged or missing goods.

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. If the unit is installed where there is a
reasonable possibility of persons or objects coming into contact with the impeller whilst
operational, a guard should be fi tted or steps taken to prevent this.
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 in accordance with Health and Safety and
Building Regulations. For confi rmation of required access please see the appropriate unit outline
drawing; note that some access doors are hinged.
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 airfl ow and reduce performance.
Consideration must also be given by the installer for adequate illumination of the unit location in
order for safe maintenance.
Handles, lids, housings and coil connections must NOT be used as lifting points
Larger NRG units are sectional. It is important to ensure that all sections are joined together
securely prior to positioning and installation.
Units that are supplied in one section as standard will be factory assembled with the appropriate
fi xings. Units over 2.5 metres in length and units with fi tted silencers may be supplied in
sections, and some site assembly will be required. Units supplied in sectional form should be
assembled using self-adhesive rubber tape at the joints prior to assembly so as to prevent air
leakage; replace with similar if damaged.
Units should only be supported using the support feet or channel base as provided by VES with the
unit. Contact VES before attempting to support the unit using alternative methods.
Only experienced fi tters should undertake this work.
Take necessary safety precautions when working in elevated positions.
For associated components (inverters, speed controllers, controls) please refer to the relevant
accompanying O&M

When moving the unit, handle with care and
in such a manner as to avoid damaging the
external fi nish 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 see right.
