INTRODUCTION

Overview

Thank you for choosing VertEx as your fume or dust control system. Please read this document before

installation and use.

This document details maintenance activities which are essential to the safe use of your VertEx. We

recommend that the Responsible Person reads this manual fully prior to installation and operation of the VertEx.

This document refers to the VertEx range. Models of this type are available with a range of filter configurations.

The filter configuration in use is detailed on the system Commissioning Certificate and is used within this

document to provide filter-specific maintenance information.

About VertEx

VertEx is a self-contained cross draught extraction system which utilises a fan and filter combination selected

for your specific application, to extract and filter dust/fumes and return filtered air to the work place.

Some models vary in filtration and filtered air delivery point.

It is used by running the fan at either fixed speed or variable speed (if speed controller fitted) to draw the

pollutant away and through the filters, allowing work or the process to proceed next to the face.

About this Document

This document provides general maintenance and operation instructions for the VertEx range. It should be read

in conjunction with the Commissioning Certificate supplied with the unit. If you have any concerns or doubts

about maintenance or operation of this unit, contact the manufacturer.

INSTALLATION

General

Unpack the unit and check for damage, if not already completed.

The VertEx must be installed on a flat and level floor capable of carrying the weight of the unit. For nominal unit

weights, see Specifications section at rear of manual. When determining an installation location, be aware that

the air exhaust must discharge somewhere. Do not position the unit so all outlets are blocked.

These models are designed to be moved into place using a forklift or pallet truck, taking care not to damage

fittings on the base of the unit.

Please note installation may be required when using certain accessories, external fansets, or ducting (see

below).

Modular System

VertEx units are built as modular systems. For ease of shipping and installation, the top section may be shipped

separately. The top section is fitted with forklift eyes to enable positioning; note that these eyes are not

designed to lift the complete VertEx unit.

If using a forklift to position the top section on the base section, always ensure operators are fully trained and

that other users are outside the working zone of the forklift. Once loosely positioned, ensure mounting holes are

aligned and seal tape is not disturbed; then bolt top section into position.

Do not move the unit while the top section is not securely fastened.

If in doubt, contact us for advice.

Electrical

WIRING

VertEx is supplied as standard with an internal fan or fans. These are pre-wired to a switch or speed controller

and fitted with a lead and plug for your convenience. Standard electrical supply is 240V/1Ph/50Hz. Certain

models can be supplied with 110V/1Ph/50Hz internal fans if specified in advance; this is noted on the front left

of each unit where applicable.

BS7671 requires that the lead is appropriate for the working environment and you must satisfy yourself that the

pre fitted lead is satisfactory.

VertEx can be supplied configured for multi-unit installations. In this instance a single electrical panel with

plugged connections will be provided.

EARTH BONDING

If in doubt consult a qualified electrician.

FUSES

Switched units: A fuse is provided on the switch front plate.

Speed controlled units: An additional fuse is provided within the speed control panel. To check this fuse,

remove the service panel; the speed control panel is mounted on the rear of the service panel.

Ducted Units

As standard, VertExes are configured to discharge upwards through the top of the unit, without ductwork.

Ducting should not be retrofitted to the discharge from the unit without consultation with the manufacturer.

When configured for exhaust to atmosphere via ductwork a discharge spigot will be visible. These units are

designed to connect to ductwork of the same size as the discharge spigot (generally 250 or 300 mm diameter).

Ducting should be installed by a professional and should not provide greater than 100 Pascals resistance.

Flexible ducting should be avoided as it may cause excessive back-pressure on the fan, and lead to reduced

airflow.

Any other configuration is non-standard and should be discussed with the manufacturer.

Assembly of Accessories

These items apply only when they have been ordered with the VertEx.

ENCLOSURE

Enclosures are supplied flat packed for assembly at point of use. Each enclosure is supplied with installation

drawings and assembly should follow the process laid out in these drawings.

COMMISSIONING

General

The initial commissioning and testing of your VertEx has been performed prior to delivery. However, as part of

in-house commissioning we recommend that you complete the following tasks and record the results as

appropriate in the system logbook.

In House Commissioning

The following tasks should be completed by a responsible person; for example, the Health and Safety Officer,

or Director, responsible for this process.

-Review the commissioning certificate for this unit, in particular any notes made by our engineer in relation to

use.

-Ensure all operators are trained to use this machine and are aware of the effective capture zone in which

they should aim to work.

-Ensure all operators are aware of the filter maintenance routine required for this machine.

Once complete, you should note this on the commissioning certificate and retain the certificate for future

reference.

As operating conditions vary, each installation will vary in maintenance needs and this is best established by

empirical means, regularly checking filter condition in the first weeks of operation to establish a procedure.

Reduced airflow is a key indication of filter condition. If the filter pressure gauge on the front of the unit is

showing in the red zone, this indicates low airflow and filters should be checked and cleaned or changed

promptly, according to the instructions contained within this manual.

We recommend keeping the commissioning certificate, Quick Start guide, and logbook with the machine at all

times for operator access.

If in doubt please contact the manufacturer quoting the machine serial number.

OPERATION

This page contains the same information as the Quick Start guide provided with your VertEx.

Prior to use

Check the system logbook to ensure no routine maintenance is required.

General use

To use VertEx, ensure it is plugged in to a mains socket and the socket is switched on. Turn on the switch on

the front of the bench.

If a speed controller is fitted, turn it to full power before switching on, then adjust it to an appropriate level. Our

recommended settings are shown below:

Fume: 50-75%

Light dusts, 50-100%

Heavy dusts, 75-100%

During commissioning, an optimum setting may have been determined and this should be noted in the system

logbook.

Note that the fan will take some time to initialise and come to maximum power. Extraction is not fully effective

until the fan has reached full power.

Check the filter pressure gauge on the front of the unit. If the needle on the gauge is showing in the upper red

zone, check the filter condition –they may require cleaning or replacement. This can also be checked against

the filter inspection pressure drop readings in the Commissioning Certificate.

Your VertEx has a zone in front of the surface in which capture is most effective, extending approximately 1m

forwards in normal use when no enclosure is fitted. This zone forms a box in which you should aim to do the

majority of your work. Working outside this zone may reduce the effectiveness of the extraction. If an enclosure

is fitted, you should aim where possible to work within the enclosure.

Continue to work as normal, aiming to work within the extraction zone described above. On completion of

work, switch the VertEx off using the switch on the front.

Record any maintenance you have undertaken, or any that is required, in the logbook.

To avoid fan overload, do not block more than 50% of the face or the air outlet.

MAINTENANCE

Filter care

The filters are not self-cleaning and must be maintained / cleaned / replaced as described below. Proper filter

care is essential for the effective operation of your VertEx. If in doubt, contact the manufacturer for advice.

When changing filters, the seals on which the filters sit should be checked for damage and replaced if

necessary.

All filters should be regularly checked for wear, damage, or by-passing.

When completing filter maintenance activities these should be recorded in the accompanying log sheet.

Take precautions and wear appropriate PPE when handing filters.

They may contain hazardous dusts.

If using a vacuum cleaner to empty filters, excessive cleaning will reduce filter life.

Remove excess dust only.

FILTER ACCESS

The filters are held into position by clamping bars mounted to the rear of each door.

To open the door, use a screwdriver to turn the quarter turn latches towards the centre of the unit. Do not

release the final latch without supporting the door.

Lift the door upwards out of the locating pins, and place to one side.

Filters can then be removed in order. When replacing filters, they should be installed in the order in which they

were fitted; which is detailed in the Commissioning Certificate.
