3.0 Packing
All packing is in accordance to the specific requirements of the individual purchase order
or contract as well as to the regulations of the country of destination.
3.1 Choice of the Packing Type
The choice of the packing type and the requirement of particular protections depend on
characteristics of the equipment and material to be packed, its handling requirements
and kind of transport chosen.
The packing provides both mechanical and environmental protection.
3.2 Wood treatment
All solid wood,used for packing (including wooden pallets) is treated (heat treatment or
fumigation) according to the international standard ISPM 15 (IPPC),latest revision.
As these rules are not the same for all countries, the procedure is to meet the demands of
a country of final destination.
3.3 Pallets
Equipment is packed on pallets that provide adequate load support during transportation
and storage. The pallets have a dynamic load capacity,enough to carry the mass loaded
on the pallet.
Where feasible the top surface of the pallet must be flat.
The pallet must be tight on all sides with steel or synthetic straps on each side.
Bolts, clamps, supporting beams, etc. will properly fix all equipment and materials.
Fragile, easily damageable and loose parts will be pertaining to the equipment securely
and properly packed in a separate case.
3.4 Handling
Under no circumstances may the equipment itself be used as a platform for gaining access
to installation and construction areas above. If such access is required then suitable
scaffolding must be established, the equipment may not be used as a support.
3.5 Centre of gravity
If required, large and heavy equipment are marked with Centre of Gravity (COG).
3.6 Labelling and tagging of equipment / Identification
If no specific identification is required, (see the Purchase Order for the technical
specifications) the labeling is in accordance to JEVI standard.
On demand the identification label is in accordance with the final packing list/delivery
note.
3.7 Shipping marks / labelling
All packages are marked or labelled in accordance with the data shown
in the packing list/delivery note

08099901 8
4.0 Transportation
The product is packed according to agreement, with indication of CoG if required by
customer.
The product is packed on pallets. The packing is easily moved either by forklift or by use
of crane, handled by authorised personnel.
For lifting lugs, see GA
For weight, see GA or rating plate
For COG - if any, see GA
CAUTION
Heating elements must NOT be used for lifting, this causes
damage on the elements
4.1 HVAC
All Heaters and inserts weighing > 25kg are supplied with lifting devices.
Lifting lugs

5.0 Storage and preservation
The purpose of this chapter is to specify how to handle and preserve a product from the
day of shipment until the equipment is installed and commissioned.
Following conditions shall be observed for the installation/construction period.
CAUTION
During storage, prior to installation the unit must be stored
dry with a relative humidity <60 %, temperature >15ºC.
CAUTION
Replace desiccant bag in junction boxes and enclosures (if
any) every 6 months.
Keep a log of the replacements as documentation.
CAUTION
The Anti condensation heater, if any, must be powered up
and connected at all time.
5.1 Preservation during the transportation and pre-installation period
The packaging provides both mechanical and environmental protection. If the equipment
is intended for service in an outdoor environment, to avoid any risk of harmful metallic dust
during storage it is protected with enveloping plastic foil.
All openings such as cable entry holes are adequately sealed.
Packages must not be opened, or their integrity disturbed during the transport.
Packing may only be opened when the equipment has been taken from storage and has
been transported to its intended location of installation, or to connect the anti-condensation
heater, after which the packing must be resealed. Storage preservation measures are
immediately invalidated as soon as the packaging is disturbed.
One shall inspect packages on receipt at the storage warehouse and at regular monthly
intervals during the storage period in regard to external damages. Any visible damage that
may have a consequence to the condition of the contents or integrity of the preservation
must be immediately documented and reported. In case of such an event, the supplier
must be contacted immediately for advice
5.2 Preservation during the installation/construction period
The product must be unpacked only when the equipment is to be installed, or to connect
the anti-condensation heater. It is recommended to maintain the integrity of the packaging
during transport from the storage warehouse to the installation site.
Inspect the equipment within each package for damage and condition as soon as the
package is opened. Report and document any damage immediately. In case of such an
event, the supplier must be contacted immediately for advice.
Installation and handling of the equipment once unpacked must be performed in
accordance with the relevant elements of the documentation for the equipment delivered.
