Protection against static charges

Electronic components are sensitive to static charging and can be

destroyed by discharges. Before you touch any of the components

inside the 754 Dialysis Unit, you should earth yourself and any tools

you are using by touching an earthed object (e.g. housing of the

instrument or a radiator) to eliminate any static charges which exist.

General precautionary rules

Handling of solvents

Check all pump tubings and all input and output leads periodically for

possible leaks. Follow the relevant instructions regarding the handling

of flammable and/or toxic solvents and their disposal.

Regular exchange of pump tubings

Pump tubings constitute consumable material and must be replaced

from time to time (see section 4.4). Suitable measures must be taken

so that any leak which might occur in the pump tubing or connections

during unattended operation will cause no damage (placing the

instrument at the bottom, collection device for any liquid which may

leak out).
