Before attempting to carry out any work on our units, all accompanying documentation
including warning labels on the unit must be referenced.
Should it be necessary to remove any component ensure that these 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 rest.
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 been allowed to completely cool before attempting
any work to the unit
For units featuring dual hinge/handle access, please see page 5 for further details
For bottom access units, should it be necessary to remove the heat exchanger from the unit
casework take care to ensure that all components are correctly supported during their removal.
Remove the lids and central mullion from the unit, exposing the bypass damper. As an additional
safety measure some components are held into place using PK screws. Remove the required
components with care and ensure all components are replaced correctly.
