5QL3 Pump

WARNING

Injury and/or damage due to reacting, flammable, or explosive substances

During the dosing procedure, substances could be combined and cause an exothermic reaction

or explosion. This includes powders, liquids, and gases.

The sample characteristics and related hazards is the full responsibility of the instrument owner.

1 Be aware of possible hazards associated with reacting, flammable, or explosive substances.

2 Ensure a working temperature low enough to prevent the formation of flames or an

explosion.

WARNING

Injury or death due to toxic, explosive, or flammable substances

If you use toxic, explosive, or flammable liquids with the pump, the exhaust air will be contam-

inated.

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 the pump or the 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.

3 Design and Function

3.1 Function description

The QL3 pump is used together with the Q3 dosing module or the QLX3 liquid module to dose liquids. The

setup also involves the QLL kit for bottle, which includes the liquid dosing head and all required tubing. The

pump builds pressure in the bottle through the air tube. When the pressure is high enough, the micro

dispensing valve in the liquid dosing head opens and liquid can ascend the liquid tube. Up to 3 bottles can be

connected to the pump simultaneously, and several pumps can be connected to the balance.

The contaminated exhaust air can be collected from an air outlet. Pressure can also be build up by connecting

a gas container to the air inlet. Otherwise, the air inlet is connected to a muffler, which is used to absorb the

noise.

4.3 Connecting the tubes

Tubes definition

1

2

The liquid tube is the thinner tube (1) used for transporting

liquid from the bottle to the liquid dosing head. The air tube

is the slightly bigger tube (2) used for pumping air into the

bottle. By adding air through the air tube, pressure rises in

the bottle. When the pressure reaches the target pressure,

between 0.3 and 0.5bar (4.4 to 7.2psi), the micro

dispensing valve in the dosing head opens and liquid can

ascend the liquid tube.

8.2 Explanatory notes for the METTLER TOLEDO AC/DC adapter

The certified external AC/DC adapter complies to the requirements for Class II double insulated equipment. It is

not provided with a protective earth connection but with a functional earth connection for EMC purposes. This

earth connection is not a safety feature. Further information about the compliance of our products can be found

in the "Declaration of Conformity" delivered with every product.

In case of testing with regard to the European Directive 2001/95/EC, the AC/DC adapter and the instrument

have to be handled as Class II double insulated equipment.

Consequently, a grounding test is not required. It is

not necessary to carry out a grounding test between

the earth connector of the power plug and any

exposed part of the metallic housing of the

instrument.

Because the instrument is sensitive to static charges,

a leakage resistor of 10kΩ is connected between the

earth connector (1) and the negative pole (2) of the

AC/DC adapter. The arrangement is shown in the

equivalent circuit diagram. This resistor is not part of

the electrical safety arrangement and does not require

testing at regular intervals.
