Installation
3 hours of operation and completely discard it
once the system is clean, as it will eventually
deteriorate and small pieces going into the blower
can cause serious damage. A horizontal or vertical
airfl ow piping confi guration is easily achieved by
rearranging the mounting feet position.
Hazards Associated With Hazardous
Process Fluids
DANGER
!
It shall be the responsibility
of the installer to ensure that
piping is adequate, sealing
between pipe joints is adequate
for the process fl uids and
proper process and pressure
protection devices are in place.
It is also the responsibility
of the installer to assure that
process gasses are not vented
in a manner that would be
hazardous.
Refer to the manufacturer of the
process media to assure that
proper safety precautions are in
place.
Blockage or Restriction
WARNING
!
Damage to the blower could occur if there is
blockage in the inlet or outlet ports or piping.
Care should be taken when installing the
blower to assure that there are no foreign
objects or restrictions in the ports or piping.
COOLING COILS (OPTIONAL)
CAUTION
!
If the blower is to be located outdoors or in a
building where the temperature surrounding
the blower or the water supply and return
piping can fall below 35°F (2°C), then care
must be taken to ensure that the water
(or other cooling liquid) does not freeze
and cause damage. Cooling coils must be
drained of liquid during downtime unless a
recirculating unit using a glycol mixture has
been installed.
Water cooled end plates are discontinued.
Consult factory for connection details.
Units are never shipped from the manufacturer
with liquid in the end plates or cooling coils.
Blowers supplied with cooling coils can be
identifi ed by the letter located in the 13th position
of the complete blower model number.
Tuthill Vacuum & Blower Systems recommends
water cooling for blowers in applications where the
blower operates with discharge temperatures of
250°F (120°C) for periods of 4 hours or more per
day. Water cooling reduces oil temperature and
improves oil viscosity for better lubrication. A water
fl ow of 0.5 – 1.0 GPM (1.9 – 3.8 L/min) is generally
suffi cient to maintain oil temperatures of 150°F
(65°C) or below. Do not allow water pressure to
exceed 75 psig (510 kPa g).
