MAINTENANCE
The TV 551/701 Navigator does not require any maintenance.
Any work performed on the system must be carried out by au-
thorized personnel.
WARNING!
Before carrying out any work on the system, disconnect it from
the mains, vent the pump by opening the appropriate valve,
wait until the rotor has stopped turning and wait until the sur-
face temperature of the pump falls below 50 °C.
In the case of breakdown, contact your local Varian service
center who can supply a reconditioned system to replace that
broken down.
NOTE
Before returning the system to the constructor for repairs, or
replacement with a reconditioned unit, the "Health and Safety"
sheet attached to this instruction manual must be filled-in and
sent to the local sales office. A copy of the sheet must be in-
serted in the system package before shipping.
If a system is to be scrapped, it must be disposed of in accor-
dance with the specific national standards.
Meaning of the "WEEE" logo found in labels
The following symbol is applied in accordance with the EC
WEEE (Waste Electrical and Electronic Equipment) Directive.
This symbol (valid only in countries of the European Com-
munity) indicates that the product it applies to must NOT be
disposed of together with ordinary domestic or industrial waste
but must be sent to a differentiated waste collection system.
The end user is therefore invited to contact the supplier of the
device, whether the Parent Company or a retailer, to initiate the
collection and disposal process after checking the contractual
terms and conditions of sale.
