Cautions tell you about dangerous conditions that can occur and cause damage to the pump
if you do not obey all of the instructions in this manual.
1. CAUTION: Refer all service, repair and calibrations only to qualified technical personnel. Unauthorised
modifications to the pump must not be carried out.
2. CAUTION: Do not autoclave, steam sterilize, ETO sterilise or subject the pump to temperatures in excess
of 45° C (113° F). Excessive temperatures may cause damage to the pump.
3. CAUTION: To prevent serious damage to the pump it must not be immersed in any liquids or exposed to
strong organic solvents. Wipe off spills immediately. Do not allow fluid or residues to remain on the pump.
Additionally, the pump is not designed to allow it to be sterilised. Failure to observe these cautions may
cause internal damage to the pump.
4. CAUTION: Carry out periodic cleaning following the detailed instructions in this manual Do not use
unapproved cleaning agents.
5. CAUTION: When turning the pump on, if screens similar to those illustrated are not displayed, do not use
the pump, and send the pump to authorised service personnel.
6. CAUTION: Only carry the pump by the handle. Failure to do so may result in damage to the pump, or the
pump may be dropped which could cause internal damage to the pump.
7. CAUTION: The backlight has a limited life and may, if used constantly, cause the light to dim. Eventually the
message display may then need to be replaced. To preserve the life of the message display, you should
only turn on the Message Display Light as described here if it is specifically required. Misuse of this
feature could lead to both battery and LCD depletion.
8. CAUTION: The Functional and Accuracy Check should be performed following any significant disassembly
or repair of the pumps.
9. CAUTION: The circuit boards consist primarily of surface mounted technology, component level repairs
are not recommended.
10. CAUTION: Disconnect the battery connection P104 on I/O board before disassembling the circuit boards to
avoid circuit damage. After disconnecting P104, press the
On/Off key twice to discharge the circuitry.
11. CAUTION: Handling of printed circuit boards is required during disassembly/assembly. A static controlled
work station including a conductive mat and grounded wrist strap should be used to provide protection
against electrostatic discharge (ESD) or circuit board damage could result.
12. CAUTION: Do not use a screwdriver or other sharp instrument to separate the front and rear housing as
this action could cause pump damage.
13. CAUTION: Do not damage or puncture the kapton tape. If the tape is damaged or punctured it could result
in the pump not being ESD protected. Special care should be taken when placing the kapton tape and also
when assembling the front and rear cases together as the front case lugs may puncture the tape.
14. CAUTION: Crossed wires must be shielded with suitable insulation as described. Failure to carry out the
procedure as specified may result in permanent damage to the LCD.
