WARNING!

... indicates a potentially dangerous situation which can

result in serious injury or death if not avoided.

Information

... points out useful tips, recommendations and information

for ecient and trouble-free operation.

2. Safety

WARNING!

Before installation, commissioning and operation, ensure

that the appropriate inclined tube manometer has been

selected in terms of measuring range, design and specic

measuring conditions.

Non-observance can result in serious injury and/or damage

to the equipment.

Further important safety instructions can be found in the

individual chapters of these operating instructions.

2.1 Intended use

This inclined tube manometer is used for the monitoring of ventilators,

blowers and lters in air-conditioning and clean room applications in dry,

clean, non-aggressive gases, primarily air.

The instrument has been designed and built solely for the intended use

described here, and may only be used accordingly.

The manufacturer shall not be liable for claims of any type based on

operation contrary to the intended use.

4. Design and function / 5. Transport, packaging ...

4. Design and function

Description

The pressure dierential between the lower and higher pressure is

indicated by the movement of an inclined liquid column.The higher

the pressure, the more the liquid is displaced upwards. A glass tube,

which has been lled with liquid to a specic extent, is used for this. The

pressure can be easily read on the scale.

Scope of delivery

Cross-check the scope of delivery with the delivery note.

5. Transport, packaging and storage

5.1 Transport

Check the inclined tube manometer for any damage that may have been

caused by transport. Obvious damage must be reported immediately.

5.2 Packaging

Do not remove packaging until just before mounting.

Keep the packaging as it will provide optimum protection during

transport (e.g. change in installation site, sending for repair).

5.3 Storage

Permissible conditions at the place of storage

Storage temperature: -40 ... +60 °C

Protect the instruments from moisture and dust.

6. Commissioning, operation

Installation

■

The inclined tube manometer must be screw-tted on a suitable

vertical surface

■

The instrument has to be mounted horizontally using the attached

self-tapping screws.

Filling

Turn the zero button back up until the stop. Then turn approximately one

rotation in a clockwise direction, so that the adjustment can be made in

both directions. Unscrew the ll button and ll the measuring instrument

liquid until the liquid is visible near the zero point on the measuring

scale. Make an accurate adjustment with the zero button and then

re-seal the lling hole.

Connection to the air lter

Make the hose connection between the ⊖ connection of the measuring

instrument with the downstream side of the lter and the ⊕ connection

of the measuring instrument with the upstream side of the lter. Stick

the green and red labels next to each other on the scale, in order

to mark the initial (green) and nal pressure (red). Please note the

recommendations of the plant manufacturer regarding the maximum

allowable pressure drop values.

Information

The inclined tube manometer is specially designed

to prevent leakage of the indicator uid in the case of

overpressure.
