9. Maintenance
WARNING: UNEXPECTED RESTART
Failure or malfunction of the central control system (unexpected start-up) or danger of a
pump restarting automatically after switching off due to a fault. Crushing, cutting or
cutting off by touching moving parts due to recurring start command or power supply.
Before carrying out maintenance or service work, disconnect the pump from the power
supply, secure it against being switched on again, determine that it is de-energised,
ground and short-circuit it and cover/isolate adjacent live parts.
CAUTION: HOT EQUIPMENT
Scalding by touching hot equipment or lubricants. Danger of scalding when opening the
hot pump with hot operating fluid or cooling-water. Open outlet or inlet port for
operating fluids only if the operating fluid has adapted to the room temperature. Wear
suitable protective equipment.
CAUTION: HIGH PRESSURE GAS
Danger due to incorrect connection of the pump to the system to be pumped out.
Pressure build-up in the vacuum system. Check correct connection of inlet and outlet
flanges before operation. When using the pump with seal gas, protect the seal gas supply
so that no overpressure can occur in the pump system in the event of a malfunction or
power interruption.
9.1 Return the equipment or components for service
Before you send your equipment to us for service or for any other reason, you must send us
a completed Declaration of Contamination of Vacuum Equipment and Components – Form
HS2. The HS2 form tells us if any substances found in the equipment are hazardous, which is
important for the safety of our employees and all other people involved in the service of
your equipment. The hazard information also lets us select the correct procedures to service
your equipment.
We provide instructions for completing the form in the Declaration of Contamination of
Vacuum equipment and Components – Procedure HS1.
If you are returning a vacuum pump, note the following:
▪ If a pump is configured to suit the application, make a record of the configuration
before returning the pump. All replacement pumps will be supplied with default
factory settings.
▪ Do not return a pump with accessories fitted. Remove all accessories and retain them
for future use.
▪ The instruction in the returns procedure to drain all fluids does not apply to the
lubricant in pump oil reservoirs.
Download the latest documents from www.edwardsvacuum.com/HSForms/ , follow the
procedure in HS1, fill in the electronic HS2 form, print it, sign it, and return the signed copy
to us.
