WEEE Directive
Background
The goal of the WEEE Directive is to encourage design of environment-friendly products that increase reuse, recycling and other forms
of recovery to reduce waste streams and applies to listed Electronic and Electrical Equipment (EEE) and Koehler's equipment falls broadly
into Appendix 1A; Section 9 Monitoring and Control Equipment: Measuring, weighing or adjusting appliances for household or as
laboratory equipment.
Any associated non-embedded equipment such as Lighting (Saybolt Color) and PCs/Printers also fall under WEEE. If provided with an
order these ancillary items must be WEEE compliant. For these and other reasons (printer cartridges are regionalized) the equipment
must be supplied through a third party supplier in Europe.
The WEEE Directive applies to electrical and electronic equipment falling under the categories set out in Annex IA provided that the
equipment concerned is not part of another type of equipment that does not fall within the scope of this Directive. Annex IB contains a list
of products which fall under the categories set out in Annex IA.
http://eur-lex.europa.eu/LexUriServ/LexUriServ.do?uri=OJ:L:2003:037:0024:0038:en:PDF
We do not qualify for any of the 10 exemption categories.
http://www.dpa-system.dk/en/WEEE/Products/Exemptions
Professional use
For equipment defined for ’professional use’ local authorities have no role to play. Producers and importers are basically responsible for
collection of WEEE recyclables from the professional user and for subsequent management. A separate statement is given cataloging
the items that require separation from the equipment along with basic information on subsequent processing or recycling prior to disposal
of the equipment.
http://www.dpa-system.dk/en/WEEE/Products/Private-or-professional-use
Responsibility for Registration and Annual Reporting:
Koehler will not sell directly to end users in the EU and so has no responsibility to register within each EU state and to make annual
reports. Koehler declares that this responsibility is born by the importer who is the first level of the distribution chain and is subject to
producer responsibility. We will communicate this in writing to our distributor/importers in the EU stating they are responsible to satisfy
WEEE registration and reporting requirements in the EU states where they conduct sales activities.
It is illegal to market electrical and electronic equipment covered by producer responsibility without being registered.
http://www.dpa-system.dk/en/WEEE/Producers/Whoissubjecttoproducerresponsibility
Product Design
Koehler's designs allow for complete disassembly to a modular level which usually allows for standard recycling. A qualified refrigeration
system technician must be consulted when disassembling and de-commissioning any equipment with refrigeration systems.
Koehler's scientific testing equipment is robustly designed to function over a long service life and are typically repaired many times over
the course of years rather than being replaced. We believe that re-use and refurbishment is the very best form of re-cycling.
All batteries must be readily removable not soldered in place.

Recycling instructions
In the event that replacement becomes necessary, we will include instructions, particularized to each instrument that informs the customer
of their recycling responsibilities and giving them guidance in doing this. All Koehler equipment has been placed on the market since 13th
August 2005 and so Koehler is defined as a "new WEEE producer". As such we must provide information on refurbishment, treatment,
and re-use.
Our instrument manual will include this compliance statement and indicate that any collection of materials will be handled by their
authorized distributor. In the event that the distributor is unreachable or is no longer a distributor for Koehler Instrument, Co., other
arrangements may be made including accepting the materials directly.
Recycling is free of charge. Shipping is the responsibility of the end users. Whether shipping to a distributor or to Koehler directly, safe,
properly declared, and labeled packaging and shipping expenses are the sole responsibility of the end user.
WEEE Marking
Since Koehler products are subject to the WEEE Directive we must display the WEEE symbol shown above in accordance with European
Standard EN 50419 on the equipment. It must be indelible, at least 5mm in height, and clearly legible. If the equipment is too small the
mark must be in the product literature, guarantee certificate, or on the packaging. Rules on marking are established in section 49 of the
WEEE Order.
Koehler Instrument Company, Inc.
c/o RECYCLING
1595 Sycamore, Ave.
Bohemia, NY 11716
As a minimum the following substances, preparations and components have to be removed from any separately collected WEEE:
- Mercury containing components, such as switches or backlighting lamps (compact fluorescent lamps, CFL),
- Batteries
- Printed circuit boards if the surface of the printed circuit board is greater than 10 square centimeters (about 4 sq in.),
- Toner cartridges, liquid and pasty, as well as color toner,
- Chlorofluorocarbons (CFC), hydrochlorofluorocarbons (HCFC) or hydrofluorocarbons (HFC), hydrocarbons (HC)
- Liquid crystal displays (together with their casing where appropriate) of a surface greater than 100 square centimeters and all those
back-lighted with gas discharge lamps,
- External electric cables
- Components containing refractory ceramic fibers as described in Commission Directive 97/69/EC of 5 December 1997 adapting to
technical progress Council Directive 67/548/EEC relating to the classification, packaging and labeling of dangerous substances (2),
- Electrolyte capacitors containing substances of concern (height > 25 mm, diameter > 25 mm or proportionately similar volume)
2. The following components of WEEE that is separately collected have to be treated as indicated:
- Equipment containing gases that are ozone depleting or have a global warming potential (GWP) above 15, such as those contained in
foams and refrigeration circuits: the gases must be properly extracted and properly treated. Ozone-depleting gases must be treated in
accordance with Regulation (EC) No 2037/2000 of the European Parliament and of the Council of 29 June 2000 on substances that
deplete the ozone layer (4).

2. Check labeling for correct orientation of instrument. (e.g. This Side Up)
3. Carefully open top of box with box cutter and remove packing foam.
4. Look inside bath from top of box, to verify that the Glass Bath Jar is in tact.
5. Make two additional vertical cuts, using box cutter, along length of two sides of the box and remove packing foam.
6. Extract instrument and place on suitable cart for transportation to work area / lab bench.
WARNING: Be sure two or more individuals are available for extracting and lifting instrument from box to cart and from cart
to bench. Individuals must lift in accordance to proper technique. See Figure below.
7. Lift instrument from cart and place on bench.
8. Remove foam insert Borosilicate Glass Jar as per steps 9 thru 19.
9. Using a flat head screwdriver, remove the four (4) silver screws located at the four corners of the back panel.
10. Remove the back panel plate and set aside.
11. A collection of wires runs from the lower control panel up the left side, while looking at the back of the bath. Halfway up the
wiring are three points where the wires can be disconnected. See Figure below:
12. There are a total of three joints to disconnect. First disconnect the single large cluster of wires by pressing in the sides of the
lower plastic piece then pulling the top plastic piece.
13. Then disconnect the two smaller joints. Each side of the joint is labeled with an identical number one (1) or number two (2).
This makes for easy connection when re-assembling the instrument.
