Unpack And Inspect; Locate The Pump - Edwards RV3 Instruction Manual

▪ 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 restricted. Maximum exhaust

is fitted, ensure the pump cannot be operated the pump with the valve closed.
▪ Provide for a purge of inert gas when shutting down the pumping system, to dilute
dangerous gases to safe concentrations. A suitable gas ballast adaptor for
introduction of purge gas into the pump is available as an accessory (see
ballast adaptor
dilution requirements if required.

4.3 Unpack and inspect

WARNING:
The mass of the RV8 and RV12 pumps is approximately 29 kg.
For the RV8 and RV12 pumps attach the mechanical lifting equipment to the lifting
bracket on the pump. Slings do not need to be used to move the RV8 and RV12
pumps.
1. Remove all packing materials and remove the pump from its packing-box.
2. Remove the protective covers from the inlet and outlet-ports and inspect 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 supplier's invoice number. Retain all the packing materials for inspection.
Do not use the pump if it is damaged.
If the pump is not to be used immediately, replace the protective covers. Store the pump
in the conditions, described in
disposal of materials.

4.4 Locate the pump

The RV3 and RV5 pumps have a lifting handle enabling the pump to be moved by hand.
If using mechanical lifting equipment, do not attach the equipment to the handle; for
stability, use slings around the motor and the pump-body.
Provide a firm, level platform for the pump. Locate the pump so that the oil-level sight-
glass is visible and the oil filler-plug, oil drain-plug, mode selector and gas-ballast control
are accessible.
If the pump will be located inside an enclosure, to ensure the ambient temperature
around the pump does not exceed 40 °C, adequate ventilation is required at both ends
of the pump. There must be a minimum space of 25 mm between the pump and the
enclosure walls.
