Connect the pump to a minimum of 80 psi (551.6 kPa/5.52 bars) clean, dry,
lightly lubricated compressed air. Make
the 1 /
8
” NPT connection at the pump
package .
4-5 Making Electrical Connections
Single-blower vacuum/pressure systems and dual-blower continuous vacuum and/or
pressure systems require connection to a 3-phase power supply. The control unit is
mounted on the vacuum unit or mounted in a remote location. Refer to local electrical
codes and the connection diagram and schematic enclosed with the unit.
Note: Refer to the specific electrical schematic included in your Customer Information
Packet when making electrical connections. Make sure all electrical connections
are tight.
Use the following as a general reference:
Power Drop
Check the nameplate voltage and amperage on the control unit and on each motor
in the system. Voltage must be within plus or minus five percent (±5%) of the
nameplate voltage.
• Bring properly sized power leads, in conduit, to the control unit. Bring power
through a properly-sized fused disconnect switch with approved lockout,
supplied by the customer.
• Ground the control unit for operator safety and equipment protection.
Rotary Airlock Motor
Run three wires from the rotary airlock motor back to the control unit.
IMPORTANT! Make sure the motor leads are connected so the rotary airlock
rotates in the proper direction. Refer to the electrical
schematic included in your Customer Information Packet to
verify terminal connection points.
Reverse any two motor leads to change direction.
