Viscosity Process Analyzer VISC-4 Maintenance Do not clean the touchscreen window with aggressive solvents or scour- ing agents and do not clean with instrument air or steam cleaners. The touchscreen is a part of the control box and therefore fulfils a protective function and must not be damaged.
Viscosity Process Analyzer VISC-4 Maintenance 10.4 Rinsing and emptying product-carrying components NOTICE Rinsing and emptying product-carrying components is a pre- requisite for many maintenance tasks. Special note is made of this in the individual sections on maintenance work. In the following sections, products which are capable of flowing at room tem- perature are referred to as low or normally viscous products.
Page 129
Viscosity Process Analyzer VISC-4 Maintenance For devices with sample treatment: Close valve 15 (see Figure 4.6 on page 63). NOTICE Only the analyzer and not the sample treatment is rinsed and emptied. The sample treatment remains filled with product.
Viscosity Process Analyzer VISC-4 Maintenance Turn the flow controller to maximum (see page 67). The product is pressed out of the analyzer and also out of the pressure differential transmitter and its supply lines. Force the product residues out of the analyzer with the purge gas.
Page 131
Viscosity Process Analyzer VISC-4 Maintenance Liquids and gases under pressure WARNING Danger of injuries due to rinsing medium with high vapor pressure! When feeding in rinsing medium with a high vapor pressure in components which have not yet cooled down, the pressure rises considerably.
Page 132
Viscosity Process Analyzer VISC-4 Maintenance WARNING Danger of suffocation when inert gas is in use! If inert gas is used to rinse the analyzer, there is a danger of suffocation if the concentration of the gas in the air becomes too high as a result of leaks or unsealed connections.
