About this file
This document is a preliminary equipment layout and installation study for a GE Healthcare Revolution Apex Elite Power Core CT scanner system at Lyndon B. Johnson General Hospital in Houston, Texas. The detailed technical drawing provides a comprehensive equipment layout for a CT exam room and control room, specifying the precise placement of 16 different equipment components including a gantry, patient table, power distribution units, system cabinets, and other critical medical imaging infrastructure. The study outlines specific spatial requirements, with the exam room measuring 22'-0" by 11'-4¼" and the control room measuring 21'-1½" by 22'-3⅞", and includes critical technical specifications for temperature, humidity, power supply, and equipment delivery requirements.
The technical document specifies stringent power and environmental conditions for the CT system installation, including a 3-phase power supply with voltage ranges of 380/400/420/440/460/480V, frequency of 50/60 Hz, and a maximum power demand of 150 kVA with an average continuous power demand of 11 kVA. Temperature and humidity specifications are precisely defined for both exam and control rooms, with recommended temperatures between 18°C to 26°C and relative humidity ranges of 30% to 70% non-condensing. The study emphasizes the need for proper site preparation, with disclaimers that the drawings are preliminary and final site conditions may significantly impact room layout and installation, requiring verification by a qualified structural engineer and radiological physicist to ensure proper equipment support and radiation protection.

GE HealthCare does not take responsibility for any damages resulting from changes on drawings made by others. Errors may occur by not referring to the complete set of final issue drawings. GE HealthCare cannot accept responsibility for any damage due to the partial use of GE HealthCare final issue drawings, however caused. All dimensions are in millimeters unless otherwise specified. Do not scale from printed pdf files. GE HealthCare accepts no responsibility or liability for defective work due to scaling from these drawings.
A mandatory component of this drawing set is the GE HealthCare Pre Installation manual. Failure to reference the Pre Installation manual will result in incomplete documentation required for site design and preparation.

DELIVERY
THE CUSTOMER/CONTRACTOR SHOULD:
· Provide an area adjacent to the installation site for delivery and unloading of the GE equipment.
· Ensure that the dimensions of all doors, corridors, ceiling heights are sufficient to accommodate the movement of GE equipment from the delivery area into the definitive installation room.
· Ensure that access routes for equipment will accommodate the weights of the equipment and any transportation, lifting and rigging equipment.
· Ensure that all necessary arrangements for stopping and unloading on public or private property not belonging to the customer have been made.

AIR RENEWAL
According to local standards.

NOTE
In case of using air conditioning systems that have a risk of water leakage it is recommended not to install it above electric equipment or to take measures to protect the equipment from dropping water.
· Power supply should come into a main disconnect panel (MDP) containing the protective units and controls.
· Governing electrical codes may require a neutral wire. If present, neutral must be terminated in MDP.
· The section of the supply cable should be calculated in accordance with its length and the maximum permissible voltage drops.
· There must be discrimination between supply cable protective device at the beginning of the installation
(main low-voltage transformer side) and the protective devices in the MDP.
· Potential future upgrade may require a Maximum Power Demand of 200 kVA to be compatible.
SUPPLY CHARACTERISTICS
· Power input must be separate from any others which may generate transients (elevators, air conditioning, radiology rooms equipped with high speed film changers...).
· All equipment (lighting, power outlets, etc...) installed with GE system components must be powered separately.
· The minimum recommended size for a dedicated distribution transformer is: 225 kVA, rated 2.4% regulation at unity power factor. Resultant maximum allowable feeder regulation is 3.6%.
· Phase imbalance 2% maximum.
· Transients must be less than 1500V peak. (on a 400V line)
· Maximum source regulation allowable is 6%. The combination of daily voltage variation (no load) and source regulation under full load shall not exceed + 10/-13% of nominal.

This drawing is a preliminary drawing. Site conditions and/or equipment configuration may have a significant impact on room layout and site preparation. Final study must be done before installation of the GE equipment. GE cannot accept any responsibility for errors due to lack of information.
The room dimensions used to create the equipment layout may originate from a previous layout and may not be accurate as they may not have been verified on site. GE cannot take any responsibility for errors due to lack of information.
It is the responsibility of the customer to prepare the site in accordance with the specifications stated in the final drawings. These drawings are not to be used for actual construction purposes. The company cannot take responsibility for any damage resulting therefrom.
The customer must ensure the floor strength is sufficient to support the fixings as required. A qualified structural engineer must be consulted and all work carried out according to his specifications.
Suitable radiological protection must be determined by a qualified radiological physicist in conformation with local regulations. GE does not take responsibility for the specification or provision of radio-protection.
