OPERATING
The upper temperature limit for blower operation
is 400°F (205°C), measured in the exhaust gas
stream with a low-mass thermocouple. When
this temperature limit switch is installed, as
the temperature exceeds the predetermined
temperature, the blower motor will stop and cannot
be restarted until the temperature drops below the
trip setting of the temperature switch.
DANGER
!
The blower is not intended to be used
with explosive products or in explosive
environments. The blower is not intended
to be used in applications that include
hazardous and toxic gases. Consult the
factory for support. Gas application units
must be fully approved by the Tuthill factory
prior to the purchase of the product and
must be designed specifically for the gas
application.
WARNING
!
Physical harm may occur if human body parts
are in contact or exposed to the process
vacuum. Assure that all connections are
protected from human contact.
WARNING
!
If rated vacuum or pressure levels are
exceeded, process fluids will migrate to other
parts of the blower and system.
WARNING
!
The blower can generate excessive noise,
hearing protection is required while the unit is
in operation.
CAUTION
!
Do not touch hot surfaces.
The upper limit of the blower
operation is 400º F (205º C). Do
not touch the blower while it is
in operation and assure blower
is cool when not in operation.
CAUTION
!
Use of a thermowell insulates the
thermocouple. Invalid and delayed readings
will result. This can result in ineffective
protection devices.
The upper temperature limits are not intended
for continuous operation. Consult with factory
for detailed information assistance.
STOPPING
CAUTION
!
Do not stop the blower if there are high
outlet pressures in the outlet piping. Unload
the outlet piping prior to shutting down the
blower.
Stop the blower by turning off the motor. Isolate
the blower from the vacuum system, and vent the
blower to atmosphere. Turn off the cooling water if
the blower is water cooled. Stop the backing pump.
See the component instruction manual.
