Unpack And Inspect; Locate The Pump - Edwards E1M18 Instruction Manual

▪ Avoid high levels of heat input to the pump from the process gases, otherwise the
pump may overheat and seize, and cause the motor thermal overload device to
open.
▪ If using the pump in a high ambient temperature with a high gas throughput, the
temperature of the pump body may exceed 70 °C. We recommend the use of
additional guarding to prevent contact with hot surfaces under these conditions.
▪ Make sure that the exhaust pipeline cannot become blocked. If an outlet-isolation
valve is fitted, make sure the pump cannot be operated with the valve closed.
▪ Provide for a purge of inert gas when the pumping system is shut down, to dilute
dangerous gases to safe concentrations. A suitable gas-ballast control valve for
introduction of purge gas into the pump is available as an accessory (refer to
ballast valve on page
Contact our application team for further advice on dilution requirements if required.

1. Remove all packing materials and protective covers and check the pump. If the
pump is damaged, notify the supplier and the carrier in writing within three days;
state the item number of the pump together with the order number and the

the pump if it is damaged.
2. Check that the package contains the items listed. If any of these items are missing,
notify the supplier within three days.
If the pump is not to be used immediately, replace the protective covers. Store the pump

Attach mechanical lifting equipment to the eye on the pump. Failure to do so can
result in injury to people or damage to the pump. Refer to

The pump can be either free-standing on its box section skids, or be fixed by bolts
through the four fixing holes in the box section skids, or be used with vibration isolators.
