GENERAL
WARNING
!
Do not operate without guards
in place.
Assure that the guard is in
place and secure prior to
operation.
CAUTION
!
Do not operate the pump in an enclosed area
unless the pump discharge is filtered or piped
to open air. Prolonged inhalation of oil mist or
vapors is a health hazard.
Do not block or restrict the flow of gas from
the pump discharge. Back pressure within the
pump could cause severe damage.
Electrical Connections
WARNING
!
Disconnect pump from source electrical
power prior to making repairs or adjustments
of any electric component of the unit.
If the pump is not wired when received, wire the
motor as per the schematic/label on the motor.
Also, wire any optional controls prior to start-up.
Connect the motor and all applicable electrical
accessories to a motor controller equipped with
both overcurrent running protection and short-
circuit protection.
When wiring is complete, turn the pump by hand
to ensure that the pump is free to turn and then
momentarily jog the motor to check that the pump
rotation direction is clockwise when facing the drive
end. If the pump rotates in the wrong direction,
reverse any two of the three motor leads. If a flow
switch is provided, it should be wired into the motor
circuit with a relay so as to stop the motor in the
event that the cooling water flow is interrupted.
Optional custom control panels and electrical
accessory components, along with schematic
wiring diagrams and wiring instructions, are
available separately from Tuthill Vacuum & Blower
Systems.
