8.2 Service request protocol
If the Wellwash 4 Mk 2 requires service, contact your local Thermo Fisher
Scientific representative or Thermo Fisher Scientific’s service department. DO
NOT under any circumstances send the instrument for service without any prior
contact. It is imperative to indicate the fault and nature of the required service.
This will ensure a faster return of the instrument to the customer.
Your Thermo Fisher Scientific representative or distributor will take care of
sending a complaint form (Complaint-order) to Thermo Fisher Scientific’s
service department. The Complaint-order contains a more detailed description
of the fault, symptom or condition. Give all the necessary information to the
distributor, who will fill in and forward the Complaint-order to Thermo Fisher
Scientific’s service department.
Check Section 7.4 How to pack for service. You will find instructions on how to
proceed before shipping the instrument for service.
Check that any necessary decontamination procedure has been carried out
before packing. See Section 7.3 Decontamination procedure. Ensure that the
Certificate of Decontamination (see Appendix B) as well as the return
authorization number (RGA) are sent with the instrument.
Thermo Fisher Scientific’s service department will keep you up to date with the
progress of service and provide you with any further details you might need,
e.g., on maintenance, serviceability, troubleshooting and replacement.
8.3 Limitations, warnings and cautions
This instrument is designed to provide full user protection. When correctly
installed, operated and maintained, it will present no hazard to the user.
The following recommendations are given for added user safety.
8.3.1 Liquid reservoir – IMPORTANT
Due to the nature of the materials used for the manufacture of our reservoir
bottles, our suppliers have recommended that they are replaced after two years
of use. This replacement policy must be more frequent if the bottles are stored
or used in direct sunlight for long periods of time.
Thermo Fisher Scientific Oy is aware of a potential leak in the pressure bottles
when they have been subjected to long periods of UV radiation. Although this
occurrence is very rare, our customers are urged to follow this piece of advice.
Bottles are available from Thermo Fisher Scientific Oy for the Wellwash 4 Mk 2
(Cat. no. WW934/1). See Chapter 10 Ordering Information.
8.3.2 Electrical
Ensure that the mains supply cable supplied with the unit is always used. If a
correct type of mains cable is not provided, use only cables certified by the
local authorities.
The mains plug should only be inserted into a socket outlet provided with a
protective ground contact. The protective action must not be negated by use of
an extension cable without a protective ground wire.
Warning: DO NOT replace fuses without first disconnecting the mains supply
cable. Only use fuses specified by Thermo Fisher Scientific Oy.
