3. INSTRUCTIONS FOR USE
1. Open the door by raising the handle fully upward and back. This gives access
to the paddle compartment.
2. Place the bag(s) into the paddle compartment leaving 50 to 60mm
protruding above the bag clamp and close the door thus clamping the
bag(s).
3. When switching on, the POWER switch illuminates and the Stomacher®
preselects the NORM. speed setting; the indicator in the touch pad shows this
by illuminating. The timer is set at zero.
4. If required, either the LOW or HIGH speed can be selected by pressing the
appropriate key. Note the audible signal and indicator illumination,
5. The stomaching process is initiated by the selection of a timed or continuous
cycle. Again note the audible signal and indicator illumination.
6. The stomaching process continues in normal circumstances until either: -
A) The timed cycle has finished
B) The ‘stop’ control pad has been touched
C) The door has been opened
D) The power has been switched off
WARNING:- Opening the door during the operating cycle causes the instrument
to stop. However, this must not be considered as the normal method for stopping
the instrument.
If events B, C or D occur the timer automatically resets to zero.
7. After processing, simply open the door and remove the bag(s). The instrument
is immediately ready for processing the next sample.
NOTE: -
A motor electrical current limiting device is incorporated into the control circuit.
Upon initial start-up, a short time may elapse before the motor builds up torque
and runs normally. This condition is more likely to prevail under the following
circumstances:
i) Upon initial start-up following a period of transportation or storage
ii) The instrument has been stored in a cold environment (less than 10°C
allowing the rubber connectors to become stiff).
For condition (i) run the instrument for 5-10 minutes, preferably with a number
of stop-start cycles. For condition (ii) allow the instrument to stand in a warm
environment as detailed in Section 5.3, followed by a short period of running with
stop-start cycles.
4. MAINTENANCE
4.1 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.
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.
4.2 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.
4.3 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.
