Dulcodes UV-Desinfektionsanlage Notes on safety of ProMinent¨ metering pumps

Safety devices

The following safety notice must be affixed to the pump (with PP, PC and PV liquid ends, acrylic glass cover, ...)

ATTENTION

Because of danger of electrostatical

ignition use damp cloth only

for wiping plastic parts!

EC conformity declaration / certificates

The EC conformity declaration for pumps for explosion-threatened workplaces is supplied with the pump (the copy of the EC conformity declaration for the pump itself does not apply to pumps designed for explosion-threatened workplaces).

The EC conformity declarations, the EC series prototype test reports and the operating manuals for the individual components are also supplied with the pump.

1.2General notes

WARNING

¥The equipment/devices may only be used for their intended purpose.

¥ProMinent¨ metering pumps must not be assembled with parts which are not tested and recommended by ProMinent otherwise this can lead to injury to persons and damage to property for which no liability will be accepted!

¥Pumps must be accessible at all times to facilitate operation and maintenance. Access points must not be obstructed or blocked!

¥Before carrying out any maintenance and repair work always drain off and flush out the liquid end first if hazardous or unknown metered media are used!

¥When metering hazardous or unknown liquids, always wear safety clothing (safety goggles, gloves, ...) when working on the liquid end!

¥You must observe the guidelines in this operating instructions manual and the ÓGeneral operating instructions manual for ProMinent¨ motor-driven metering pumps and hydraulic accessoiresÓ on assembly, installation and maintenance!

1.3Notes on installation, start-up and operation

WARNING

¥The metering pump can contain water residue in the liquid end as the result of testing at the factory!

If handling media which must not come in contact with water, all traces of water must be removed from the liquid end before start-up! For this purpose, turn the pump through 180û and drain off the liquid end then flush with a suitable medium from above via the intake connection!

¥Do not connect mains voltage to the control cable!

¥When operating the metering pump against a closed shut-off element on the pressure side or in the event of pressure peaks during the metering stroke, the system pressure can reach a multiple of the maximum permissible operating pressure that can conse- quently cause the pressure line to burst!

¥To avoid this situation, an overflow is recommended for the purpose of limiting the maximum permissible operating pressure of the pump or system.

¥Do not connect a metal bypass line to the overflow valve on the PVT delivery unit! This could cause cracks in the delivery unit!
