Edwards nXLi Series User Manual

Maintenance and service
General main
tenance
The system requires no user maintenance. Maintenance must be carried out by Edwards
service centres (refer to Service on page 27). The frequency of maintenance operaons
depends on the process. Adjust the frequency of maintenance operaons according to user
experience.
Edwards recommend carrying out a monthly visual inspecon of the dry pumping system
where it is installed. Check that the electrical supply cord, hoses and pipelines bringing
services to the pump are in good condion and ensure that all connecons are secure.
Service
It is recommended that the pump be serviced every 5 years. The pump should then be
returned to an Edwards service centre.
Edwards products are supported by a world-wide network of Edwards Service Centres. Each
Service Centre oers a wide range of opons including: equipment decontaminaon; service
exchange; repair; rebuild and tesng to factory specicaons. Equipment which has been
serviced, repaired or rebuilt is returned with a full warranty.
Local Service Centres can also provide Edwards engineers to support on-site maintenance,
service or repair of equipment. For more informaon about service opons, contact the
nearest Service Centre or other Edwards company.
Returning a pump for service
When returning a pump to a Service Centre, use the returns procedures in the HS1 form.
Follow the procedure in Figure 10 on page 38 and ensure that a completed Figure 11 on
page 39 form is returned with the pump.
The instrucon in the returns procedure to drain all uids does not apply to the lubricant in
the pump oil reser
voirs. Do not return the pump with the accessories ed. Remove all
accessories and retain them for future use.
If the pump is congured to suit the applicaon, make a record of the conguraon before
returning the pump. All replacement pumps will be supplied with default factory sengs.
Edwards products, spares and accessories are available from Edwards companies in Belgium,
Brazil, China, France, Germany, Israel, Italy, Japan, Korea, Singapore, United Kingdom, U.S.A.
and a world-wide network of distributors. The majority of these centres employ Service
Engineers who have undergone comprehensive Edwards training courses.
Order spare parts and accessories from the nearest Edwards company or distributor. When
ordering, state for each part required:
• Model and Item Number of the equipment
• Serial number
• Item Number and descripon of part.
