Receipt of equipment
Depending on the order placed with your supplier; the
equipment will either be delivered as separate modules, for ease
of movement and assembly on site, or as full / sectional
assemblies complete with a base frame.
In either case a dimensional drawing of the system will be
supplied (attached to the supply fan module). The installer must
check that the delivered items correspond with those detailed on
the drawing.
Note: when assembling the system, the specified position of the
components with the associated orientation and airflow
directional restraints must be followed.
Lifting, moving and storage of equipment
When moving the units follow the procedure as shown in the
diagrams. Do not attach lifting devices other than those shown.
When using slings ensure that spreaders are employed to
prevent damage to the unit casings.
Equipment should be stored in a dry location and protected from
the accumulation of building dust and debris.
Do not stack the equipment during storage. Ensure that no
impact loads are applied to the equipment
The handles fitted to the side panels of the units are for panel
removal only. DO NOT attempt to move the unit using the
handles.
Note: Avoid the panel handles when lifting. Consider the
centre of gravity of the unit- this is not always central to the unit.
