2.0 Description of product
The duct heater is designed for heating of air. Reference should be made to the general drawing of this item for the intended use: Drawing no. : Refer to equipment drawing GA Electric supply : See electrical diagram Voltage : See electrical diagram Ref. number : Same as order number and item number
The heater consists of an enclosure (IP rating according to GA and/or Datasheet). Containing: Certified electric heating elements (Ex e II) max load of 1,3 W/cm².
A protective device with manual reset (TSHH) Ex de IIC Gb. Optional, protective device with auto reset (TSH) Ex de IIC Gb Alternative protective device, TSHH, thermocouple sensor type K connected to certified transmitter, Ex ia IIC T4...T6 Ga end user applies barrier, reset must be done by hand. Temperature sensors are placed at the highest temperature areas of the heating bundle. In case of no airflow the TSHH will cut off the heater.
Optionally the certified equipment mentioned below may be fitted into the junction box. A certified Ex ia IIC T4 temperature transmitter. A certified Ex d IIC T5 anti-condensation heater. A certified Ex de IIC T6 or Ex d IIC T6 or Ex e IIC T6 control device.

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
