Page 8: Important Notes On Pressure Fluctuations
3 Construction and function When properly purged, the hand pump will generate positive pressure quickly. The construction of the hand pump means that the same pressure is generated for the test item as for the reference test gauge. The pressure is set to the necessary value using the fine adjustment valve. With the pressure relief valve, the pressure can be relieved into the reservoir. For the assessment of the test sample, the pressure displayed on the reference manometer is compared with the measurement value. -
Page 9: Purging Hydraulic Lines
4 Purging hydraulic lines In order for the hand pump to be operated, it is vital that its connections with the refe- rence gauge and the test item are pressure-resistant. Furthermore, for the best measurement procedure possible, sufficient and correct purging of the measurement device is required. -
Page 10: Handling
4 Purging hydraulic lines CAUTION! Demineralized water! During the quality inspection of the HTP1, a functional test is carried out with demine- ralised water. The reservoir may therefore contain residues of this liquid. â Check the compatibility with your application and remove the residue using appro- priate measures (e.g. -
Page 11: Generating Pressure
5 Handling 5.1 Generating pressure After the purging the hydraulic lines, pressure can be created with the hand pump. With increasing back-pressure in the system, the pumping process becomes increa- singly difficult. WARNING! There is a risk of injury if the maximum pressure is exceeded! Note the maximum permitted pressures of the individual components in the measure- ment device. - Page 12 5 Handling TIP! At high pressures, open the handle only slightly. The handles can be compressed more easily the further the handles are closed. In this way, you can create high pressures more easily and meter the pressure better. â The higher the pressure is, the less you should open the handles.

5 Handling Increasing pressure with the fine adjustment valve Pump body stop collar Alternatively, you can increase the pressure with the fine adjustment valve. â Turn the hand wheel in a clockwise direction in the direction of the “pump body stop collar”. Depending on the pressure of the test item and the setting of the hand wheel, pressure Storage / transportation can be achieved quite easily. -
Page 14: Releasing Pressure
5 Handling 5.3 Releasing pressure Once the pressure measurements have been completed, the positive pressure in the hand pump, the test item and in the pressure hose need to be brought into balance. CAUTION! Risk of injury through excessive pressure! Do not remove any connected components (test item, pressure hose, reference gauge) if the hand pump is under pressure. -

6 Problems CAUTION! Material damage! The hand pump cannot be repaired by the operator! In the case of a defect, the appli- ance must be sent back to the manufacturer for repair. â Never open up the hand pump and / or carry out any repairs yourself. The table below describes steps that can be taken in the event of a malfunction. -

7 Maintenance / cleaning, storage and transportation Maintenance No maintenance is required for the hand pump and it cannot be repaired by the opera- tor either. In the case of a defect the appliance must be sent back to the manufacturer for repair. -
Page 17: Disposal
8 Disposal The hand pump consists of various different materials. It should not be disposed of with household waste. â Take the hand pump to your local recycling plant â send the hand pump back to your supplier or to KELLER. -
