2-3-1 Purchaser Responsibilities
The work and materials needed to prepare the site is the responsibility of the purchaser. Delay,
confusion, and waste of manpower can be avoided by completing pre installation work before delivery.
Use the Pre installation checklist to verify that all needed steps have been taken. Purchaser
responsibility includes:
• Procuring the materials required.
• Completing the preparations before delivery of the ultrasound system.
• Paying the costs for any alterations and modifications not specifically provided in the sales contract.
NOTE: All electrical installations that are preliminary to the positioning of the equipment at the site prepared for
the equipment must be performed by licensed electrical contractors. Other connections between pieces
of electrical equipment, calibrations, and testing must also be performed by qualified personnel. The
products involved (and the accompanying electrical installations) are highly sophisticated and special
engineering competence is required. All electrical work on these products must comply with the
requirements of applicable electrical codes. The purchaser of GE equipment must only utilize qualified
personnel to perform electrical servicing on the equipment.
The desire to use a non–listed or customer provided product or to place an approved product further
from the system than the interface kit allows presents challenges to the installation team. To avoid
delays during installation, such variances should be made known to the individuals or group performing
the installation at the earliest possible date (preferably prior to the purchase).
The ultrasound suite must be clean prior to delivery of the machine. Carpet is not recommended
because it collects dust and creates static. Potential sources of EMI (electromagnetic interference)
should also be investigated before delivery. Dirt, static, and EMI can negatively impact system reliability.
2-3-2 Required Features
NOTE: GE Medical Systems requires a dedicated power and ground for the proper operation of its
Ultrasound equipment. This dedicated power shall originate at the last distribution panel before
the system. The dedicated line shall consist of one phase, a neutral (not shared with any other
circuit), and a full size ground wire from the distribution panel to the Ultrasound outlet. Please
note that image artifacts can occur, if at any time within the facility, the ground from the main
facility's incoming power source to the Ultrasound unit is only a conduit.
• Door opening is at least 76 cm (30 in) wide.
• Proposed location for unit is at least 0.3 m (1 ft.) from the wall for cooling
• Power outlet and place for any external peripheral are within 2 m (6.5 ft) of each other with
peripheral within 1 m of the unit to connect cables.
NOTE: The Voluson® 730 has four outlets inside the unit. One is for the monitor and three for on board
peripherals.
