130 1100 Series Nano Pump Service Manual
3 Repairing the Pump
Exchanging Internal Parts
The procedures in this section describe how to exchange internal parts. You
must remove the nano pump from the stack in order to open the main cover.
The following procedures require opening the main cover of the nano pump. Always
ensure the nano pump is disconnected from the line power when the main cover is
removed. The security lever at the power input socket prevents that the pump cover
is taken off when line power is still connected.
To disconnect the nano pump from line, unplug the power cord. The power supply
still uses some power, even if the switch on the front panel is turned off.
When opening capillary or tube fittings solvents may leak out. Please observe
appropriate safety procedures (for example, goggles, safety gloves and protective
clothing) as described in the material handling and safety data sheet supplied by the
solvent vendor, especially when toxic or hazardous solvents are used.
The electronics of the nano pump will not allow operation of the nano pump when the top
cover and the top foam are removed. A safety light switch on the main board will inhibit the
operation of the nano pump. Always operate the nano pump with the top foam and top
covers in place.
Internal components may be sensitive to electrostatic discharge (ESD). Always use an
ESD kit when handling internal parts.
