Installation
The 604S drives are fitted with pumpheads which incorporate an electrical
"safe-guard" isolation switch which will disable the drive when the pumphead
is opened or removed. To fit the pumphead first remove the cover from the
cased drive. Pass the pumphead guard switch wires through the front panel
of the drive and connect to the terminal block as shown below.

Fit the track over the drive spindle and locating boss. Tighten the track
retaining screws. After checking that the drive spindle has been completely
degreased, slide the rotor into position. The rotor is attached to the drive
spindle via a split collet, and it is important that the rotor retaining screw is
fully tightened a torque of 13Nm to prevent slipping when the pump is being
used.
To remove the track, remove any tubing from the pumphead, and swing out
the crank handle to expose the door retaining screw. Turn the screw
counterclockwise one turn to release the collet, and withdraw the rotor from
the shaft. Loosen the track locating screw and pull the track clear. Rotate the
track to its new position and tighten the track locating screw.
Ingress protection standard will be compromised if the gasket and seals
are not properly replaced.
