Installation, Operation and Maintenance Manual

Maintenance

6

Before attempting to carry out any work on VES units, all accompanying documentation
including warning labels on the unit must be referenced.
Should it be necessary to remove any component, ensure they are secured into position once
reinstalled. It is critical that after any maintenance work has been conducted that all
components removed/replaced be refitted correctly by a competent engineer.

Before attempting to carry out any maintenance work, investigative or repair 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 complete standstill.
Care should also be taken when accessing external units as the wind and elements may cause
moving parts to ‘windmill’.

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.

When accessing the unit 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 particularly important with
bottom access units. Ensure the AHU has come to a complete stop before attempting any work
on the unit
