WARNING
Injury or death due to toxic substances
If you use toxic, explosive, or flammable liquids with the pump, the exhaust air will be
contaminated.
− Connect a tube to the exhaust air outlet to collect the contaminated air.
WARNING
Injury and/or damage due to reacting substances
When pressure is released from the bottle, the air/gas in the bottle moves back towards the
pump. The air/gas coming from the coupled outlets mixes in the pump. Molecules of the
substances in the various bottles can get in contact through this contaminated air/gas.
1 Do not connect bottles with incompatible liquids to the same pump simultaneously.
2 Before connecting a second, incompatible liquid to the pump, disconnect the first bottle
and purge the pump cavity with clean air/gas.
WARNING
Injury and damage to pump or bottle due to high pressure
High pressure from external gas can damage the pump or the bottle.
1 Use a regulator on the external gas line.
2 Ensure that the pressure of the external gas does not exceed 0.5bar (7.2psi).
CAUTION
Injury due to splashing liquids
If the pressure in the bottle is not released, liquid might splash when removing the micro
dosing valve, opening the bottle, or removing the liquid tube.
− Always release pressure before removing the micro dosing valve, opening the bottle, or
removing the liquid tube.
CAUTION
Injury due to leaking liquids
Wrongly cut tubing can result in leaking connections.
− Cut the tubes with a tube cutter or a sharp knife.
CAUTION
Injury due to moving parts
− Do not reach into the working area while parts of the instrument are moving.
CAUTION
Injury due to sharp objects or broken glass
Instrument components, e.g., glass, can break and lead to injuries.
− Always proceed with focus and care.
