These items determine the maximum load weight of soiled goods:
• the volume of the machine's cylinder, and
• the material and weight of the goods.
Do not try to load the machine to its maximum weight capacity with bulky fabrics.
Use the size of the machine, the type of the goods, the amount of soil, and the wash quality when
you load the machine.

tunnel washers use stainless steel with the ANSI 304
specification. This material gives good performance when chemical supplies are correctly ap-
plied. 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 dam-
age. Pellerin Milnor Corporation accepts no responsibility for chemical damage to the ma-
chines it makes or to the goods in a machine.
1.4.1 How Chemical Supplies Can Cause Damage

Dangerous Chemical Supplies and Wash Formulas — Some examples that
can 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 chemi-
cal supplies and formulas.
Incorrect Configuration or Connection of Equipment — Many chemical
systems:
• do not prevent a vacuum in the chemical tube (for example, with a vacuum breaker) when the
pump is off,
