Cautions
PRE-INSTALLATION or SERVICE
1. Before servicing a valve or other pneumatic component,
be sure that all sources of energy are turned off, the entire
pneumatic system is shut off and exhausted, and all power
sources are locked-out (ref: OSHA 1910.147, EN 1037).
2. All ROSS products, including service kits and parts, should
be installed and/or serviced only by persons having training and
experience with pneumatic equipment. Because any installation
can be tampered with or need servicing after installation,
persons responsible for the safety of others or the care of
equipment must check every installation on a regular basis and
perform all necessary maintenance.
3. All applicable instructions should be read and complied with
before using any fluid power system in order to prevent harm to
persons or equipment. In addition, overhauled or serviced valves
must be functionally tested prior to installation and use.
4. Each ROSS product should be used within its specification
limits. In addition, use only ROSS parts to repair ROSS products.
Failure to follow these directions can adversely affect the
performance of the product or result in the potential for human
injury.
FILTRATION and LUBRICATION
5. Dirt, scale, moisture, etc. are present in virtually every air
system. Although some valves are more tolerant of these
contaminants than others, best performance will be realized
if a filter is installed to clean the air supply, thus preventing
contaminants from interfering with the proper performance of the
equipment. ROSS recommends a filter with a 5-micron rating
for normal applications.
6. All standard ROSS filters and lubricators with polycarbonate
plastic bowls are designed for compressed air applications only.
Do not fail to use the metal bowl guard, where provided, to
minimize danger from high pressure fragmentation in the event
of bowl failure. Do not expose these products to certain fluids,
such as alcohol or liquefied petroleum gas, as they can cause
bowls to rupture, creating a combustible condition, hazardous
leakage, and the potential for human injury. Immediately replace
a crazed, cracked, or deteriorated bowl. When bowl gets dirty,
replace it or wipe it with a clean dry cloth. 7. Only use lubricants which are compatible with materials used
in the valves and other components in the system. Normally,
compatible lubricants are petroleum base oils with oxidation
inhibitors, an aniline point between 180°F (82°C) and 220°F (104°C),
and an ISO 32, or lighter, viscosity. Avoid oils with phosphate type
additives which can harm polyurethane components, potentially
leading to valve failure and/or human injury. If you have questions
regarding whether a lubricant used on your system is compatible
with ROSS products, please contact ROSS.
AVOID INTAKE/EXHAUST RESTRICTION
8. Do not restrict the air flow in the supply line. To do so could
reduce the pressure of the supply air below the minimum
requirements for the valve and thereby cause erratic action.
9. Do not restrict a valve’s exhaust port as this can adversely affect
its operation. Exhaust silencers must be resistant to clogging and
have flow capacities at least as great as the exhaust capacities
of the valves. Contamination of the silencer can result in reduced
flow and increased back pressure.
ROSS expressly disclaims all warranties and responsibility
for any unsatisfactory performance or injuries caused by the
use of the wrong type, wrong size, or inadequately maintained
silencer installed with a ROSS product.
POWER PRESSES
10. Mechanical power presses and other potentially
hazardous machinery using a pneumatically controlled
clutch and brake mechanism must use a press control double
valve with a monitoring device. A double valve without a self-
contained monitoring device should be used only in conjunction
with a control system which assures monitoring of the valve.
All double valve installations involving hazardous applications
should incorporate a monitoring system which inhibits further
operation of the valve and machine in the event of a failure within
the valve mechanism.
ENERGY ISOLATION/EMERGENCY STOP
11. Per specifications and regulations, ROSS L-O-X ® and manual
L-O-X ® with EEZ-ON ® operation products are defined as energy
isolation devices, NOT AS EMERGENCY STOP DEVICES.
