  • Page 19: Installation

    You must ensure that the pump is suitable for your application, If you have any doubts as to the suitability of the pump for your application, refer to the Edwards guidelines on vacuum pump and vacuum system safety (see the Associated Publication at the end of the contents list at the front of this manual).
  • Page 20: System Design

    System design Consider the following points when you design your pumping system: • Use a suitable inlet-valve to isolate the pump from your vacuum system if you need to allow the pump to warm up before you pump condensable vapours or if you need to maintain vacuum when the pump is switched off.
  • Page 21: Locate The Pump

    Locate the pump WARNING Use suitable lifting equipment to move the pump. The mass of the pumps is approximately 17 kg to 26 kg. The pump can be either free-standing on its baseplate, or fixed by bolts through the four fixing holes in the baseplate, or used with vibration isolators.
  • Page 22: Electrical Installation: Single-Phase Motors

    Electrical installation: single-phase motors WARNING Ensure that the electrical installation of the pump conforms with your local and national safety requirements. It must be connected to a suitably fused and protected electrical supply and a suitable earth point. CAUTION If your pump-motor can be used with more than one voltage range, you must ensure that the motor is configured for your electrical supply voltage and frequency.
  • Page 23: Electrical Cable Connection, Method 2

    3.6.2 Electrical cable connection, method 2 If the electrical connection diagram for your pump is Figure 10 or 11, use this method to connect the electrical supply cable. 1. Remove the cover from the motor terminal box (Figure 1, item 8). 2.

  • Page 31: Outlet Connection

    • Use a suitable catchpot you pump condensable vapours or you use the pump for very dusty applications. • Ensure that sealing surfaces are clean and scratch-free. Outlet connection WARNING Connect the pump outlet to a suitable treatment plant to prevent the discharge of dangerous gases and vapours to the surrounding atmosphere.
  • Page 32: Gas Ballast Inlet Connection

    3.10 Gas ballast inlet connection The position of the gas ballast inlet is shown in Figure 1 (item 3). The gas ballast inlet has several filters (shown in Figure 19) to trap any dust and debris if you use air as the gas ballast supply. If you want to use a different gas for the gas ballast supply, or if you want to connect a valve to the gas ballast inlet, remove the filters (as described in Section 5.6) and connect your gas supply or valve to the 1 / 4 inch BSP threaded hole.
  • Page 33: Operation

    OPERATION Gas-ballast control Use the gas-ballast control (Figure 1, item 3) to change the flow of gas-ballast into the low vacuum stage of the pump. Use the gas-ballast control closed: • to achieve ultimate vacuum • to pump dry gases. Tum the gas-ballast control 5 turns anti-clockwise to open it fully.
  • Page 34: Re-Set The Thermal Overload Device

    If the pump does not achieve the performance specified in Section 2, make sure that this is not due to your system design before you contact your supplier or Edwards for advice, In particular, the vapour pressure of all materials used in your vacuum system (including pump oil, see below) must be much lower than the specified ultimate vacuum of the pump.
  • Page 35: To Pump Condensable Vapours

    Tum the gas-ballast control fully anti-clockwise (fully open) and operate the pump for at least 1 hour (or overnight) to thoroughly purge the oil of contaminants. 3. Close the gas-ballast control. 4. Open the vacuum system isolation-valve and pump down to ultimate vacuum. To p um p condensable va p ours Use gas-ballast (open the gas-ballast control) when there is a high proportion of condensable vapours in the process gases.
  • Page 36: Shut-Down

    Single-phase motors are cooled by internal fans. These motors have either an automatic or manual reset thermal overload device. When the motor is too hot, the thermal overload device switches off the pump. If the thermal overload device has an automatic reset, when the pump cools down, the device resets and the pump will restart.
  • Page 37: Maintenance

    The pump may have overheated if it was misused, if it malfunctioned or if it was in a fire. Edwards Health and Safety Data sheets for fluorinated materials used in the pump are available on request: contact your supplier or Edwards.
  • Page 38: Maintenance Plan

    If necessary, adjust the maintenance plan according to your experience. When you maintain the pump, use Edwards spares and maintenance kits; these contain all of the components necessary to complete maintenance operations successfully. The Item Numbers of the spares and kits are given in Section 7.
  • Page 39: Replace The Oil

    Replace the oil Refer to Figure 1 for the items in brackets. Operate the pump for approximately ten minutes to warm the oil, then switch off the pump. (This lowers the viscosity of the oil and allows the oil to be drained from the pump more easily).
