2.4 - Horizontal transport
For horizontal movement pallet lifters or transport skids can
be placed under the installation frame or under the lifting
bars. It is important that these support the lifting points. At
no time should the cross beams at the ends of the unit
sections be used for jacking or tracking the AHU. FOR
HORIZONTAL TRANSPORT ALWAYS PROVIDE SUPPORT
UNDER THE LIFTING POINTS. The use of bars as rollers
can result in damage to the installation frame.
For offloading as well as hoisting lifting cables can be
attached to the lifting bars. Evenly positioned spacer bars
should be used between the lifting cables to prevent
damage to the top of the unit and ensure that no excess
pressure is applied to the side panels. For hoisting please
ensure that the weight is evenly distributed. And please use
CE marked hooks.
The AHU should not be lifted or moved under the cross
beams.
2.5 - Storage
The packaging in which the AHU is supplied can cause
condensation to be formed between the packaging and
the AHU, if the unit is stored in an unconditioned place.
Storage temperature will be between –25 to 55 oC
according to EN 60204-1. If the AHU is not immediately
used it is recommended to store it in a conditioned location
on-site. If the AHU is kept outside for a short period direct
sun radiation must be avoided.
If the fans are shut down for a longer period (longer than
three months) bearing damage can occur. To prevent this it
is recommended to loosen the belt tension or to
temporarily remove the fan belts. When the fans are
re-started the belt tension must be reset to the specified
tension. Controlled rotation of the fan impeller can also
prevent this type of damage. This is also recommended for
direct-drive fans.
2.6 - Warranty
The units will 2 years warranty after invoice date if startup,
storage and maintenance are made according to this
manuel.
2.7 - Placement
The unit have to be placed on a dry floor surface which can
handle the weight and do not give permission to slide or
vibrate. Anti vibration pads can be used if needed.
