2.2 Prevent Damage from Chemical Supplies and
Chemical Systems
BNUUUR02.C01 0000160549 A.7 E.3 B.3 1/2/20 2:14 PM Released
All Milnor®washer-extractors and CBW®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.
2.2.1 How Chemical Supplies Can Cause Damage
BNUUUR02.R01 0000160548 A.7 E.3 B.5 10/1/21 11:24 AM Released
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,
• do not prevent flow (for example, with a valve) where the chemical tube goes in the machine.
Safety

10 Pellerin Milnor Corporation
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, page 10). Some can let chemical supplies go in the machine by gravity (Figure 3, page
11).

2.2.2 Equipment and Procedures That Can Prevent Damage
BNUUUR02.R02 0000160545 A.7 E.3 B.3 1/2/20 2:14 PM Released
Use the chemical manifold supplied. — There is a manifold on the machine to at-
tach chemical tubes from a chemical pump system. The manifold has a source of water to flush
the chemical supplies with water.
Figure 4. Examples of Manifolds for Chemical Tubes. Your equipment can look different.
Safety

12 Pellerin Milnor Corporation
Close the line. — If the pump does not always close the line when it is off, use a shutoff
valve to do this.
Do not let a vacuum occur. — Supply a vacuum breaker in the chemical line that is
higher than the full level of the tank.
Flush the chemical tube with water. — If the liquid that stays in the tube between
the pump and the machine can flow in the machine, flush the tube with water after the pump
stops.
Put the chemical tube fully below the inlet. — It is also necessary that there is no
pressure in the chemical tube or tank when the system is off.

Prevent leaks. — When you do maintenance on the chemical pump system:
• Use the correct components.
• Make sure that all connections are the correct fit.
• Make sure that all connections are tight.

Do the maintenance in Section 3.1.1 : Maintenance Summary, page 13 to make sure that the ma-
chine is safe, keeps the warranty, and operates correctly. This will also decrease repair work and
unwanted shutdowns. Speak to your dealer or the Milnor® Service department if repairs are
necessary.
WARNING: Mechanisms — can can pull in and mutilate body parts.
�Do not service the machine unless qualified and authorized. You must
clearly understand the hazards and how to avoid them.
�Do not service the machine with power on except when explicitly
called for in the service instructions. Use extreme care when working near
moving components.
�Replace guards and covers that you remove for maintenance.
If you use software to keep the maintenance schedule for your plant, add the items in the follow-
ing maintenance summary to that schedule. If not, you can put marks on a calendar that work with
the tables in the maintenance summary. See Section 3.1.6 : How To Show the Maintenance On a
Calendar, page 20
3.1.1 Maintenance Summary
BNUUUH01.R02 0000334004 A.7 A.26 A.35 10/25/21 1:20 PM Released
Each of the following sections is for a type of maintenance. For example, the section “Guards
and Related Components” says “Examine these items. If an item is damaged, missing, or has the
wrong setting, correct this discrepancy immediately to prevent injury.” A table in each section
identifies the applicable items and the frequency. The “More Data” column gives special instruc-
tions if necessary.
* If the machine operates more than 12 hours each day, do the “day” items two times each day.
Do the other items at the given hours or on the days that you show on a calendar (see Section 1).
Do all items in all sections for the maintenance intervals that apply (for example, day, 40 to
60 hours, and 200 hours).
TIP: The maintenance summary has many links to the sections that follow the summary.
These sections give more information about the maintenance items. After you learn this
information, it is only necessary to look at the summary to do the maintenance.
