Material Hoses; Cleaning; Handling Hazardous Liquids, Varnishes And Paints - WAGNER ZIP52 Finishing Operating Manual

VERSION 12 / 2012
OPERATING MANUAL
4.2.3

MATERIAL HOSES

Ensure that the hose material is chemically resistant to the sprayed materials.
Ensure that the material hose is suitable for the pressure generated in the unit.
Make sure that the hoses are laid only in suitable places. In no case, should hoses be laid
in the following places:
– in high traffic areas,
– on sharp edges,
– on moving parts or
– on hot surfaces
Make sure that the hoses are never used to pull or move the equipment.
The electrical resistance of the complete high pressure hose must be less than 1 MOhm.
Several liquids have a high expansion coeffi cient. In some cases its volume can rise with
consequent damage to pipes, fi ttings, etc. and cause fl uid leakage.
When the pump sucks liquid from a closed container, ensure that air or suitable gas can
enter the container to avoid a vacuum being generated in the container itself. Thus a
negative pressure is avoided. The vacuum could implode the container (squeeze) and can
cause it to break. The container would leak and the liquid would fl ow out.
The pressure ratio is 1:1. Therefore the pressure generated by the pump is equal to the
input air pressure.
4.2.4

CLEANING

De-energize the unit electrically.
Disconnect the pneumatic supply line.
Relieve the pressure from the unit.
Ensure that the flash point of the cleaning agent is at least 5 K above the ambient
temperature.
To clean, use cloths and brushes moistened with solvent. Never use hard objects or
spray on cleaning agents with a gun.
An explosive gas/air mixture forms in closed containers.
When cleaning units with solvents, never spray into a closed container.
Ground the container.
4.2.5

HANDLING HAZARDOUS LIQUIDS, VARNISHES AND PAINTS

When preparing or working with paint and when cleaning the unit, follow the working
instructions of the manufacturer of the paints, solvents and cleaning agents being
used.
Take the specifi ed protective measures. In particular, wear safety goggles, protective
clothing and gloves, as well as hand protection cream if necessary.
Use a mask or a breathing apparatus if necessary.
For suffi cient health and environmental safety: Operate the unit in a spray booth or on
a spraying wall with the ventilation (extraction) switched on.
Wear suitable protective clothing when working with hot materials.
