! CAUTION
Removal or modification of sound insulation will result in high sound levels which
may be hazardous to personnel.
The Quincy QSVB models are essentially vibration free, however, some customers may choose to bolt the unit to the
floor to prevent the accidental breakage of piping or electrical connections as a result of being bumped. Only use lag
bolts to locate the unit. Do not pull the bolts down tight as this may, under certain circumstances, place the frame in
a twist or bind causing eventual breakage of fluid coolers, piping and reservoirs.
4. Piping Connections
The vacuum distribution and piping system, including the vacuum pump and all related components, must be
designed in accordance with generally accepted engineering practices. Improperly designed distribution systems can
cause damage to the vacuum pump. Exhaust piping should be installed in such a manner as to not create additional
back pressure on the vacuum pump. Also, the exhaust piping should be installed with a drip leg to prevent
condensate from falling back into the fluid reservoir. (See figure below)
5. Piping Fit-up
Care must be taken to avoid assembling the piping in a strain with the vacuum pump. Piping should line up without
having to be sprung or twisted into position. Adequate expansion loops or bends should be installed to prevent
undue stress at the vacuum pump resulting from the changes between hot and cold conditions. Pipe supports should
be mounted independently of the vacuum pump and anchored, as necessary, to limit vibration and prevent expansion
strains. In no case should the piping be of smaller size than the connection on the vacuum pump unit.
