1.7.3 Safety instructions on vacuum supply

Prior to commissioning the cham ber m ake sure that all r elevant nation al and int ernational r egulations are observed. Within the European Union, units that will be operated in potentially explosive areas have to meet the requirements of ATEX Directive 2014/34/EU.
If combustible solvent is introduced i nto the dryin g cham ber, the vacuum pump must be constructed in a suitable explosion-proof manner.
Observe the safety instructions of the pump manufacturer.
1.7.3.1 Selection and location of a suitable pump
The mixtures extrac ted f r om the inner chamber mus t be carr ie d a wa y m aking sure that there is no da nger by ignition of these atmospheres. Sparking in t he p ump motor or the switchi ng elements, electrostatic dis­charges, as well as hot pump parts can ignite solvent vapors in the event of an error. To minimize this risk, use an ATEX Directive 2014/34/EU com pliant vacuum pump suitable for s uction from Zone 0 or 1 and, if appropriate, from the zone of its installation site.
Explosion hazard due to the spread of an explosive atmosphere to unprotected pump parts and ignition due to electric sparking on the pump motor or switching el­ements, electrostatic discharges, or hot surfaces.
Serious injury or death from burns and / or explo sion pressure.
Use only suitable, explosion-proof pumps. See chap. 6.5.1. Operate the pump in a stationary position and secure it so it is immobile. Make sure that the suction line to the vacuum connection (6) of the VDL is fixed and
conductive.
Ensure sufficient solvent condensation, e.g., in an exhaust waste vapor condenser, to
avoid that ignitable solvent concentrations are conducted from the pump. Otherwise, the exhaust pipe after the pump must be fixed and conductive and suction must be done in an explosion-proof area.
Ensure equipotential bonding between the pump, the VDL vacuum drying oven and, if
appropriate, the pump module using the connections of the grounding conductors ac­cording to the grounding concept (Chap. 6.8).
Confirm that the vacuum pump is designed for a gas inlet temperature corresponding to
the used drying temperature, or take appropriate measures to cool down the extracted vapor before it enters the vacuum pump.
Use ATEX compliant vacuum pumps providing an integral protective device for the
pump OR Install a current-dependent, delayed protective device for the pump (for the triggering time of this protective device, see the manufacturer’s specifications). The pro­tective and monitoring device must not be able to turn on independently again or be re­leased.
Use ATEX compliant vacuum pumps providing an integral explosion proof switch OR
make sure that the switch gear box is either installed outside the hazardous area or that it is explosion proof.
The ATEX compliant vacuum pump offered by BINDER provides an integral protective device for the pump and an integral explosion proof switch.
DANGER
VDL (E3.1) 10/2020 Page 17/196
1.7.3.2 Observing the permissible gas inlet temperature
Confirm that the vacuum pum p / vacuum s ystem is designe d for a gas inlet tem perature corresponding to the used drying temperature, or take appropriate measures to cool down the extracted vapor before it enters the vacuum pump / vacuum system. If the gas inlet temperature is too high and then becomes even warmer by compression in th e p um p, th e r es ult ing temperature (of the gas-solvent mixture inside t he pump) could exceed the solvent’s temperature class and auto-ignition temperature. The ATEX compliant vacuum pumps offered by BINDER are designed for a gas inlet temperature of 40 °C / 104 °F max. Do NOT exceed this temperature.
DANGER
Fire and explosion hazard by exceeding th e auto-ignition temperature of the solvent due to excessive gas inlet temperature
Damage to the vacuum pump. Serious injury or death from burns and / or explosion pressure.
∅ Do NOT exceed the maximum gas inlet temperature of the pump (ATEX compliant vac-
uum pumps from BINDER: 40 °C).
When operating with a higher set-point temperature take appropriate measures to cool
down the extracted vapor before it enters into to the vacuum pump.
1.7.3.3 Technical Ventilation (extraction)
When manipulating the vacuum pump (removing the filled condensate catchpot of the pump) or in the event of an error (e.g. drop pi ng o r spil ling the filled condensate c atchpot) spreading of an ex p los ive atmosphere to unprotected parts of the pump or the vacuum drying oven would be possible.
The operator must pr ovide ac tiv e extr ac tio n (technical ventilation acc ord ing t o c ou ntry-specific regulations – TRBS 2152 P art 2 f or G e rmany) prior to comm is s ioning an d manipulating the vac uum pump. Extraction must include the entire installation area of the vacuum drying oven, the pump and, if appropriate, the pump module. Handling the pump always takes place under technical ventilation.
This will prevent spreading of an explosive atmosphere to unprotected chamber parts other than the defined area (see Chap. 3.5).
DANGER
Explosion hazard due to the spread of an explosive atmosphere to unprotected parts of the pump or the vacuum drying oven and ignition due to electric sparking or hot surfaces.
Serious injury or death from burns and / or explo sion pressure.

1.7.5 Safety instructions on operating the vacuum drying oven

Note the following points before starting up the oven: When loading the chamber and possibly at the moment of unloading, also in the context of
intended use, an explosive mixture may form in the working space. Define a safety area of at least 1m from the chamber front and ensure active extraction (technica l vent ilat i on).
The walkable installation and operating surface of the chamber must be conductive. This
installation and operating surface must be connected to the vacuum drying oven according to the grounding concept. Cyclic measurements of the equipotential bonding are required.
The operator must ensure an appropriate ventilation of the loading area in front of the
oven front prior to commissioning of the chamber.
Ensure that at no time any solvent vapors could enter in the area of the electrical installa-
tion room, preheating chamber, and controller housing (triangular instrument box).
Provide technical ventilation in the area of the vacuum pump stand, particularly in the areas
of the condensate catchpot (when emptying it) and the exhaust air of the vacuum pump.
The personal protective equipment (PPE) of the operating personnel must be ESD pro-
tected.
Only trained personnel with password authorization may work on the VDL vacuum drying
oven.
DANGER

VDL (E3.1) 10/2020 Page 20/196
The unit must not be operated without compressed air flushing at maximum overpressure and
When operating the VDL vacuum drying oven with inert gas correctly follow the technical ventilation measures, as described in the DGUV guidelines 213-850 on safe working in laboratories (for Germany).
Do not start up the chamber without active technical ventilation .
During operation with inert gas the chamber is supplied with an oxygen displacing gas (e.g. N2). Inert gases in high concentrations are hazardous to health. They are colorless and almost odorless and therefore prac­tically imperceptible. I nhalation of inert gases can c ause drowsiness up to respir a t or y arres t. When the O content of the air decreases below 18%, t here is risk of death f rom lack of oxygen. An y gas that might escape has to be led out via good room ventilation or a suitable exhaust system.
DANGER
Suffocation hazard due to high concentration of inert gas. Death by suffocation.
∅ Do NOT set up chambers in non-ventilated recesses.
Make sure that technical ventilation measures are active. Respect the relevant regulations for handling inert gases. When decommissioning the vacuum drying oven, shut off the inert gas supply.

1.9 Intended use

Following the instructions in this operating manual and conducting regular maintenance work (chap. 25) are part of the intended use.
Any use of the chambers that does not comply with the requirements specified in this Operating Manual shall be considered improper use.
Other applications than those described in this chapter are not approved. Use
VDL vacuum dr ying ovens are s uitable f or drying and heat treatm ent of solid or nonf lamm able pulveri zed charging material, as well as bulk material, using the supply of heat under vacuum.
During this process, the contained solvent may be able to form an explosive mixture with air under normal conditions. Ignition of an explos ive atmos phere is preven ted in the VD L vacuum drying ovens b y various safety measures. T he maximum dr ying temperature li es by a standard s afety factor be low the max imum permitted auto-ignit ion temperature. The drying tem perature must lie belo w the sublimation point of the loading material.
The VDL vacuum drying ovens are approved for drying of materials with organic solvents. This may cause unlimited amounts of solvents to app ear tem por aril y. The cham bers are equipp ed w ith an expl osion-proof inner chamber.
The VDL vacuum drying ovens are not intended for installation in a Zone 1 or 0. The chamber must not be installed or operated in an occas ionall y or conti nuous ly / f or long p eriods / fr equentl y poten tially explos ive area. Measures must be taken to prevent the spread of explosive atmospheres to unprotected areas.
The chamber plug (power plug) is unprotected b ecaus e it m ust be disconnec ted in case of an em ergenc y to completely sep arate the c hamber fr om the power s upply. Therefore, t he electrical connection m ust be established outside a zone.
Temperature class The temperature clas s of the inner chamber accor ding to IEC 60 079-0 is T3. It depends on t he m axim um
operation temperatur e ins id e the ov en. The auto-ignition tem peratur e is d eter mined from the safet y speci­fications of the solvent us e d. In t he cas e of s olven t mixtures, the solvent with the lowest auto-ignition tem­perature as this is critical.
According to IEC 60079-0 the VDL vacuum drying ovens are NOT suitable for the temperature classes T4, T5 and T6. Insert only substances with an auto-ignition temperature that is higher than 200 °C / 392 °F.
The information listed on the on the type plate.for explosion protection is essential for classification. For the Device category, refer to the area classification information on the s ite of installat ion in Cha p. 3.5
