ELECTRICAL CONNECTIONS
220V Connections:
 Each pump has its own 6-foot BX cable pre-wired to the electrical connection box for direct wiring to dedicated
220VAC, single phase 50/60 Hz circuit via a disconnect box with approved ground.
 Disconnect box should be mounted no more than 3 feet of each other and 3 feet of installation center line.
 The supplied cable is pre-wired in the electrical box of each pump. Connect cable wires by matching color.
Important: When not connecting a 24VDC remote switch, the ORG and YEL wires must
be tied together and the BRN wire insulated for pump operation.
24VDC Connections:
 24VDC Connections are used when installing a 24VDC remote switch. They are made via a supplied interconnect cable that is also pre-wired to the electrical connection box of each pump.
 Make the 24VDC connections shown below for the remote switch. When not using the remote switch, insulate
the BRN wire and tie the ORG and YEL wires together.

VENTILATION REQUIREMENTS
Equipment Room Temperature
The VacStar NEO equipment must be used in a controlled temperature environment. Maintain equipment room temperature between 40 and 105 degrees Fahrenheit. Adequate forced ventilation must be provided across the unit by
placing an appropriate exhaust fan opposite an equivalent air intake vent. The fan should be higher than the associated intake vent.
Exhaust Vent Protection.
If the exhaust piping is venting to the outside of the building, precautions must be taken to protect the equipment room
from weather elements and animal intrusion. This can be accomplished by using one of the three methods shown
below.
