Care and maintenance
The 604S/R uses a permanent magnet direct current motor with a pulse-
width-modulated speed controller which provides black commutation making
brush wear very slight. All 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 twelve 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. Check that the gaskets are in good condition, replace if they are
damaged. 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.
Ingress protection standard will be compromised if the gasket and seals
is not properly replaced.
