Automatic piston backflashing is effected over a rinsing pump which is
installed inside of the Smartline Pump 1000.
Preparing your Smartline Pump 1000 for automatic
piston backflushing
This SOP applies to the Smartline Pump 1000 Firmware Version 1.0X or
higher. please connect the eluent tubing as follows:
1. Connect the silicone tubing from the accessory kit to position 1 and
put the other end into the reservoir bottle (see Fig. 16 below).

2. Connect the silicone tubing from the accessory kit to position 4 and
put the other end into the waste bottle.
The self-priming piston backflushing pump is equipped with a time control
device. Once the Smartline Pump 1000 is powered on, the rinsing pump
turns on automatically for 15 seconds and fills the whole tubing and the
backside of the pistons with washing solution. The rinsing pump turns on
automatically every 2 hours for 15 seconds as long as the Smartline
Pump is on. The washing solution flows from the reservoir bottle to the
rinsing pump over position 1 and flows out from position 2 through the
pump head and then goes to the waste bottle.
For washing solution we recommend for example a solution of
water/methanol (80/20) or pure water.
Please use only pure water, methanol or isopropanol as the washing
solution in the rinsing pump. Use of other solvents (for example
THF or toluene) can cause damage to the tubing and rinsing pump.
