Grounding the unit
Make sure that the unit is properly grounded by using the grounding cable (item 2 illustration 3).
Ventilation
The air-driven extractor (item 1 illustration 1) must be connected to a metal ducting to lead the exhaust outdoors (see illustration
4).
An alternative is to lead the metal ducting into a hood that is in turn connected to a suitable ventilation system approved for Zone
1. This hood should have an open design so as to avoid constant extraction (see illustration 5).
The metal ducting may not be longer than 15 metres, and must be connected in such a way as to ensure grounding.
The unit can be used with solvents and solvent mixtures intended for spray-gun cleaning, such as acetone, toluene, isobutanol,
xylene that are listed as Group IIA according to IEC 79-20 (EN 60079-20).
In addition to the solvents classified as IIA, the unit is furthermore approved for use with the following solvents classified as IIB
under the condition that the solvents described do not exceed 70 % of the solvent mix used in the Machine:
Solvent:
Propanol (=n-propyl alkohol)
Methyl ethyl ketone (MEK) (=Butanon)
Ethylalcohol (=Ethanol)
Tetra hydro-2-furylmethanol
Further information is provided in the Instruction 17556.
The unit can also be used with water or water based solvents.
All solvents must have a pH value between 4 and 10. Be sure not to mix water-based solvents with thinner-based solvents. It is
important that all users are informed of what solvent is being used, at all times.
Never use any solvent if it is not provided with an MSDS (Material Safety Data Sheet). Read the MSDS carefully, and follow all
the instructions and procedures provided in the MSDS. If unsure, or if more information is needed concerning the solvent, please
contact your solvent supplier.
Do not add other chemicals to the solvent including, but not limited to, kerosene, gasoline, detergents, fuel oil or chlorinated
solvents.
The DRESTER Compact DC11 can be used with different types of drums, but they must comply with the following:
- The drums must fit into the unit
- The drums must be leak-free.
- The drums must be made of a conductive material.
- Check for local regulations concerning max allowed volume for keeping solvent in the unit
Solvent drums are not provided by Hedson Technologies, thus Hedson Technologies does not take any responsibility for the drums.
Follow the solvent supplier's instructions carefully.
