  • Page 7: Using Of The Bi Distillation Apparatus

    Intended Use In LAUDA Puridest Bi Distillation Apparatus models PD 2 D, PD 4 D and PD 8 D, electric heating elements serve to boil water in the mono stage boiler (left-hand side) and evaporate it. The steam is led to the steel condenser of the mono stage where it condenses on a water-cooled cooling coil.

  • Page 8: Warranty

    For all laboratory apparatus and their accessories from LAUDA-GFL Gesellschaft für Labortechnik mbH, there is a war- ranty claim, as well for spare parts, repairs and modifications, carried out by LAUDA-GFL. In order to identify defective units, we require both model and serial number on the nameplate, left-hand side of the Distillation Apparatus and, if appli- cable, a copy of the invoice.

  • Page 9: Removing The Transport Protection Of The Glass Condenser

    Removing the Transport Protection of the Glass Condenser When installing the glass condenser and the glass fittings, pay special attention due to danger of glass breakage. The glass condenser and the glass fittings are placed beneath the hood of the Distiller. In order to be able to remove the hood, two each quick-release catches on each side of the unit as well as two hidden screws (see photo below) between the hood and the basic housing need to be loosened.

  • Page 10: Water Connections

    Water Connections All water connections of the Distillation Apparatus, except the distillate withdrawals, are situated on the right-hand side of the unit. Hoses for water inlet and outlet are not included in the standard scope of supply. Tap water inlet ① The tap water inlet provides the Distillation Apparatus with water through a solenoid valve.

  • Page 11: Cooling Water Outlet ⑥

    Cooling water outlet ⑥ Connect a ¾" temperature-resistant hose to the cooling water outlet. It must not be longer than approx. 1.5 m. The hose must be led into a drain on a lower level and must have a slope on its complete length. It must be ensured that the cooling water flows off without causing backwater.

  • Page 12: Functional Description

    Distillation Apparatus for double distillation LAUDA Puridest Bi Distillation Apparatus models PD 2 D, PD 4 D und PD 8 D work fully automatically. After switching on the main switch oft he Distillation Apparatus, the green pilot lamp in the main switch (I) will light up.

  • Page 13: Maintenance, Service And Trouble Shooting

    Maintenance, Service and Trouble Shooting Caution: Before service and maintenance always let the Double Distiller cool down! Danger of scaldings! Caution: Before opening the Distillation Apparatus and before cleaning always cut off power (pull the plug or switch the main switch off). Danger of electrical shocks! 10.1 Descaling...

  • Page 14: Water Shortage In Mono Or Bi Stage

    The operational interruption "Clean" is reset by switching the unit's main switch off and then on again after 10 seconds. The LAUDA-GFL Puridest Bi Distillation Apparatuses are produced of first class materials. Nevertheless, the unit should only be subjected to mechanical strain within sensible limits.

  • Page 15: Disposal Of Old Units

    LAUDA-GFL will take responsibility, within the scope of the legal directives, for an environmentally sound handling and disposal of all used LAUDA-GFL units as of the production year 1995 that are returned to us free of charge and will have it materially recycled.

  • Page 21: Connection To The Mains Supply

    Connection to the mains supply The electrical connection must ensure an all-pole separation of the Bi Distillation Apparatus from the mains supply. In- stalled assembly parts, such as CEE shock-proof sockets or main switches, must be installed so as to ensure clear identifi- cation and they must be within easy reach in an emergency case.
