Ross Controls 3_2 VALVES SERIES DM2 D - Manual (Page 15)

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 or damage
to property.
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 or damage to property. 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 based 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 which risks human injury, and/or damage
to property.
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
must 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 an 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 ® valves and
L-O-X ® valves with EEZ-ON ® operation are defined as energy
isolation devices, NOT AS EMERGENCY STOP DEVICES.
All products sold by ROSS CONTROLS are warranted for a one-year period [with the exception of all Filters, Regulators and
Lubricators (“FRLs”) which are warranted for a period of seven years] from the date of purchase to be free of defects in material
and workmanship. ROSS’ obligation under this warranty is limited to repair or replacement of the product or refund of the purchase
price paid solely at the discretion of ROSS and provided such product is returned to ROSS freight prepaid and upon examination
by ROSS is found to be defective. This warranty becomes void in the event that product has been subject to misuse, misapplication,
improper maintenance, modification or tampering.
THE WARRANTY EXPRESSED ABOVE IS IN LIEU OF AND EXCLUSIVE OF ALL OTHER WARRANTIES AND ROSS EXPRESSLY
DISCLAIMS ALL OTHER WARRANTIES EITHER EXPRESSED OR IMPLIED WITH RESPECT TO MERCHANTABILITY OR
FITNESS FOR A PARTICULAR PURPOSE. ROSS MAKES NO WARRANTY WITH RESPECT TO ITS PRODUCTS MEETING
THE PROVISIONS OF ANY GOVERNMENTAL OCCUPATIONAL SAFETY AND/OR HEALTH LAWS OR REGULATIONS. IN NO
EVENT IS ROSS LIABLE TO PURCHASER, USER, THEIR EMPLOYEES OR OTHERS FOR INCIDENTAL OR CONSEQUENTIAL
DAMAGES WHICH MAY RESULT FROM A BREACH OF THE WARRANTY DESCRIBED ABOVE OR THE USE OR MISUSE OF
THE PRODUCTS. NO STATEMENT OF ANY REPRESENTATIVE OR EMPLOYEE OF ROSS MAY EXTEND THE LIABILITY OF
ROSS AS SET FORTH HEREIN.
