Care and maintenance
The 603S/R uses a permanent magnet direct current motor with a pulse-
width-modulated speed controller which provides back commutation making
brush wear very slight. The only maintenance that is necessary is that the
brushes be inspected every 3000 running hours and replaced when they are
at or below 6mm in length.
All moving parts of the rotor should be checked from time to time for freedom
of movement. Occasional lubrication of pivot points and rollers with light
lubricating oil will help ensure trouble free operation. If the pump needs
cleaning, use a cloth dampened with water and mild detergent. Do not use
strong solvents.
If harmful liquids are spilled on to the pump, first switch off the pump and
isolate it from the mains. To clean the pumphead remove any tubing. Then
remove the rotor by unscrewing the retaining bolt one turn anticlockwise to
release the collet and withdraw the rotor from the shaft. If the pumphead is to
be removed and cleaned, remove the eight screws securing the top cover and
disconnect the two wires leading from the reed switch mounted on the
pumphead from the terminal block to the right of the motor. Remove the track
by unscrewing the two retaining screws and detaching the track from its
spigot.
After cleaning the pumphead components, refit the pumphead ensuring the
leads of the reed switch are connected to the terminal block and that the seal
is effective. Replace all of the case screws and tighten. Refit the rotor and
ensure that the collet screw is tight.
Check for correct operation of the switched guard before putting the pump
back into service.
