Figure 2: Proper Routing of Chemical Tubing
Note 1: As shown in Figure 2, all tanks, pumps, and tubing must be lower than the injection point on the
machine and must not dribble chemicals into the machine, nor leak chemicals externally onto any portion of
the machine or its surroundings.
1.3.3. Preventing Leaks Which Can Injure Personnel and Cause
External Damage
Any ports on the inlet are plugged at the Milnor
®
factory. When replacing plugs with fittings or
when reinstalling plugs, always use the sealant furnished (LocTite
®
RTV Silicone Adhesive or
equivalent). Use properly sized hose barbs, always use clamps, and check for leaks. Use the hose
barbs furnished with your machine only if they provide the proper fit for the tubes employed.
Ensure that excessive pressures cannot build up that might burst or disconnect tubing. Instruct the
operator to monitor for leaks and report any occurences.
When calibrating injections, it is permissible to remove tubes from barbed fittings to take samples.
However, always check for leaks after installing tubes and clamps. A preferable method for
sampling is to install a three-way valve, or two two-way valves and a tee fitting, onto each injection
tube.
WARNING 1 : Avoid chemical burns and corrosion—Concentrated liquid chemicals
leaking from a chemical system can burn skin and eyes, cause other types of injury or illness, and
corrode machine components.
• Ensure that excessive pressures cannot build up which might burst or disconnect a chemical
delivery tube.
• Ensure that there are no external chemical leaks when the system is installed or calibrated.
• Periodically check the system for leaks during operation.
CAUTION 2 : Avoid corrosion and textile damage—Chemicals dribbling into the machine
when it is idle will corrode machine components and damage any textiles left in the machine.
• If possible, use a system that flushes the entire chemical delivery tube after each injection.
• If a non-flushing system is used, install tanks, pumps, and tubing below the injection point
on the machine, such that chemicals travel to the machine at an upward angle.
CAUTION 3 : Avoid explosions—Certain chemicals will react chemically when combined.
Consult with your chemical supplier representative about the safe use of chemicals.
