Ensure that the electrical supply voltage corresponds with the voltage specified on the motor data plate. Edwards recommends that connecting the electrical supply to the motor through a starter or circuit breaker that has thermal over-current protection and can be adjusted to suit the full-load current ratings shown on the motor rating plate.

A373-10-880 Issue T Edwards recommends connecting the electrical supply to the motor through a starter or circuit breaker that has thermal over-current protection and can be adjusted to suit the full-load current ratings shown on the motor rating plate. The fuse ratings must be calculated by a qualified person. The supplier of the thermal over-current protection device may specify fuse ratings to ensure correct operation of the over-current protection device.

Page 25: Leak Test The System
Leak-test the system and seal any leaks found, after installing the pump, to prevent leakage of substances out of the system and leakage of air into the system. © Edwards Limited 2014. All rights reserved. Page 19 Edwards and the Edwards logo are trademarks of Edwards Limited.

Use an inert gas purge into the pump gas ballast connection to prevent the condensation of flammable  vapours within the pump mechanism and exhaust pipeline. © Edwards Limited 2014. All rights reserved. Page 21 Edwards and the Edwards logo are trademarks of Edwards Limited.
Page 28: Gas Purges
Continually measure the inert gas purge flow rate. If the flow rate falls below that required, stop the flow of flammable gases or vapours into the pump. Note: Edwards recommends obtaining and reading the Vacuum Pump and Vacuum System Safety manual (publication number P400-40-100), available from Edwards or the supplier. Gas-ballast control...

2.2, make sure that this is not due to the system design before contacting the supplier or Edwards for advice, In particular, the vapour pressure of all materials used in the vacuum system (including pump oil, refer to below) must be much lower than the specified ultimate vacuum of the pump.
Page 30: To Pump Condensable Vapours
Section 2.1. However, Edwards recommends checking the pump at a regular interval of not more than 14 days. Check the pump more frequently if pumping high volumes of gas or if operating the pump with the gas-ballast control open. Single-phase motors are cooled by internal fans. These motors have a thermal overload device. When the motor is too hot, the thermal overload device switches off the pump.
Page 31: Maintenance
The pump may have overheated if it was misused, if it malfunctioned or if it was in a fire. Edwards Material Safety Data sheets for fluorinated materials used in the pump are available on request: contact the supplier or Edwards.
Page 32: Check The Oil-Level
Disconnect the pump from the electrical supply, remove the oil drain-plug and allow the oil to drain out of  the pump. Repeat this step until the oil reservoir is clean.  Page 26 © Edwards Limited 2014. All rights reserved. Edwards and the Edwards logo are trademarks of Edwards Limited.
