specification. This material gives good performance when chemical supplies are correctly applied.
If chemical supplies are incorrectly applied, this material can be damaged. The damage can be
very bad and it can occur quickly.
Chemical supply companies usually:
• supply chemical pump systems that put the supplies in the machine,
• connect the chemical pump system to the machine,
• write wash formulas that control the chemical concentrations.
The company that does these procedures must make sure that these procedures do not cause
damage. Pellerin Milnor Corporation accepts no responsibility for chemical damage to the
machines it makes or to the goods in a machine.

How Chemical Supplies Can Cause Damage

2.2.1.

Dangerous Chemical Supplies and Wash Formulas

2.2.1.1.
cause damage are:
• a very high concentration of chlorine bleach,
• a mixture of acid sour and hypo chlorite,
• chemical supplies (examples: chlorine bleach, hydrofluosilicic acid) that stay on the stainless
steel because they are not quickly flushed with water.
The book "Textile Laundering Technology" by Charles L. Riggs gives data about correct
chemical supplies and formulas.
Incorrect Configuration or Connection of Equipment
2.2.1.2.
• do not prevent a vacuum in the chemical tube (for example, with a vacuum breaker) when the
pump is off,
• do not prevent flow (for example, with a valve) where the chemical tube goes in the machine.
Damage will occur if a chemical supply can go in the machine when the chemical system is off.
Some configurations of components can let the chemical supplies go in the machine by a siphon
(Figure 2). Some can let chemical supplies go in the machine by gravity
