MAINTENANCE

9.1

Cleaning

The instrument should be kept externally clean by wiping over periodically with a cloth damped
with mild liquid detergent. Do not use any solvent-based cleaning agents, as they will damage the
paint finish. First switch the instrument off and disconnect from the mains electrical supply before
wiping down all the surfaces including the control panel.
CAUTION: - Ensure the equipment is switched off and unplugged from the mains electrical
supply before cleaning near any electrical components.
To facilitate cleaning the processing chamber, the door hinge lugs are open-slotted to enable the
door to be lifted from the lower pivot pins. To do this open the door in the normal way by lifting the
lid fully upward and back then pull the door sharply upwards. In the Stomacher
Biowasher, the black neoprene sheet should be removed first by unscrewing the knurled
thumbscrews.
Note that the door must not be removed on the Stomacher 3500 Thermo except by a qualified
technician as the procedure is more involved due to the electrical connections to the heater blanket,
however the neoprene sheet can be removed to assist cleaning.
A small handled brush may be helpful for cleaning. It is recommended this procedure be carried out
immediately in the event of any spillage. Refitting of the door is the reversal of the above
procedure; ensure the door hinge lugs are fully engaged on both sides before commencing use.
9.2

Replacing Primary Fuses

The primary fuses can only be removed with the aid of a tool, typically a screwdriver, since they are
not considered operative replaceable. 1n the event of a fuse failure we recommend the equipment
and mains electrical supply is checked by a competent qualified electrician.
WARNING: - When replacing fuses ensure they are replaced with fuses of the same rating and
specification, refer to the appropriate model specification section of this manual.
Please contact Seward Technical Service if in doubt.
9.3

Servicing and Spare Parts

Suitably qualified persons should only carry out internal servicing and maintenance. A Maintenance
Manual is available giving full details of servicing and repair procedures, wiring diagrams, parts
identification and general assembly drawings. We recommend as a matter of routine that the
instrument is inspected and serviced at least every six months or sooner if extensively used.
CAUTION: - This equipment should not be used if damaged in any way. If in doubt please
contact your local Seward Ltd authorised service centre.
