I. Warranty
RUWAC warrants that new equipment which are complete units and are sold and/or manufactured by RUWAC, Inc. will be
free from defects in material and workmanship for a period of 18 months from date of shipment or 12 months from date of
start-up, whichever come rst. RUWAC warrants that replacement parts sold hereunder will be free from defects in
material or workmanship for a period of 120-days after the date of shipment. RUWAC machines that have been
completely re-built at the factory will carry a 180-day warranty from date of shipment. All eld repairs preformed by
authorized RUWAC service personnel are covered by a 120-day parts only warranty.
RUWAC, Inc. will not assume any responsibility under the terms of this limited warranty on equipment, which has not been
paid in full. This warranty does not apply to any equipment that has been disassembled, repaired, or otherwise altered by
any person without the written authorization of RUWAC’S service department, nor does it apply to any product that has
been subjected to failure sure to corrosive or abrasive attack, misused, damaged, or improperly installed, nor does it apply
to motors, controls, and components not manufactured by RUWAC, Inc. Motors, controls, and other Sub vendor’s compo-
nents therefor are warranted only to the extent of the manufacture’s warranty. All warranty work on such products must be
authorized by RUWAC, Inc. and must be performed in an authorized shop as designated by the manufacturer. RUWAC
sole liability and buyer’s sole and exclusive remedy hereunder is the replacement or repair at RUWAC’S option of prod-
ucts not complying with this warranty. Such repair or replacement shall be F.O.B. RUWAC’S factory, and RUWAC
reserves the right to invoice all expenses incurred when repairs are made in the eld at the request of the customer,
except as specically set forth herein, RUWAC makes no warranty express or implied, with respect to the products and/
or service supplied hereunder, this warranty is in lieu of and excludes all other warranties, including without limitation, any
warranty of merchantability, tness for a particular purpose, or conformance to purchaser’s specications.
II. Safety
CAUTION: Standard Ruwac DS2 series machines are not to be used for the removal of liquids or any volatile,
viscous, ammable or explosive media. If you are unsure about your application requirements consult your
Ruwac representative.
CAUTION: Standard Ruwac DS2 series machines are designed for continuous use, provided the vacuum is
not held under constant stress. If you are unsure about your application requirements consult your Ruwac
representative.
CAUTION: The components in this machine can be very heavy. Always follow safe lifting procedures.
CAUTION: A dust mask should be worn when working with ne materials.
CAUTION: Machines equipped with a reverse pulse module must always be supplied adequately when the machine is
on. The module is controlled by an electrical sequential timer (requires a 110 volt power supply) or dierential pressure
switch. The module itself requires a source of compressed air of 90 PSI at 2 - 4 CFM (depending on module). This device
prevents the accumulation of material on the lter and therefore prevents the machine from being held under excessive
stresses due to material blockage.
CAUTION: Machines equipped with a motorized shaker must be supplied with a three phase, 230 - 460 volt (depending
on motor) power supply when ever the machine is on. The motorized shaker is controlled by an electrical sequential timer
(requires a 110 volt power supply), a dierential pressure switch or a manual switch. Manual switch models should be
actuated before and after every use while the vacuum is o. This device prevents the accumulation of material on the lter
and therefore prevents the machine from being held under excessive stresses due to material blockage.
CAUTION: Check motor direction. Vacuum can be produced while operating in both directions. A backwards rotation will
produce 40% less while heating the bearings, however. The motor should always run clockwise.
CAUTION: Vacuums are not design for working in classied explosion atmospheres in accordance to OSHA / NFPA
regulations.
CAUTION: Hoses and accessories must be checked for continuity prior to each use when used in a hazardous applica-
tion (i.e. combustible materials or environment).
