Chapter 1: General System Requirements

This manual provides all information necessary to prepare the site for the installation of the system, taking into consideration the information required for different professionals such as architects, construction engineers, electrical contractors, and all other personnel involved in construction and preparation of the site.

IMPORTANT

 Good site preparation is essential for a smooth and efficient installation and for proper functioning of the system.

Poor site planning may compromise system efficiency and/or patient comfort.

 The information provided in this

conjunction with the drawings and specifications prepared specifically for your site.

 If the site is considering a future system upgrade, use the pre-installation manual of the intended system type,

during site planning. Special attention should be paid to room size, floor requirements, electrical power requirements, cable paths (ducts), and environmental requirements (air conditioning for heat dissipation).

 When upgrading a system, the site’s power, structure and floor loading requirements must be evaluated for

upgrade suitability according to this manual.

Pre-Installation Manual

is general in its nature, and must always be used in

-1.1 Objectives and Overview

General System Requirements 1.2 Customer Responsibilities

1.2 Customer Responsibilities

It is the customer’s responsibility to prepare the site in accordance with all the specifications provided in this manual, and in conjunction with the site-specific drawings. It is essential to verify all aspects of the site configuration before construction is started, as subsequent changes can be costly or impractical.

A detailed checklist is provided in App.A, Customer Checklist. It is the customer’s responsibility to ensure that all requirements in the checklist are fulfilled and that the site conforms with all the specifications and requirements in this manual.

The customer is responsible for all aspects of site preparation, including, but not limited to, the following tasks:

 Assigning a project coordinator (see Project Coordination, p.1-4)  Planning and construction or renovations required for installation of the system, in accordance

with the specifications included in this manual, including:

 Room Size, Layout and Considerations, p.2-11  Equipment Description and General Construction Requirements,p.2-1  Special Construction Requirements,p.3-1  Environmental HVAC Requirements, p.4-1  Electrical Requirements,p.5-1  Network Requirements,p.6-1

General System Requirements 1.2 Customer Responsibilities

1.2.1 Using Radioactive Isotopes

 Complying with all national, state, or local regulatory requirements for the country in which

the installation occurs, for example:

 Fire control devices as required by local codes  Permits, inspections, radiation licensing etc.  Earthquake-related regulations  Local regulations for Service Clearance & Egress

 Assuring regulatory compliance for the use of radioactive isotopes and preparation of the

required isotopes (see Using Radioactive Isotopes, p.1-3)

 Safe storage of the system and auxiliary equipment prior to and during installation  Floor tile removal and replacement in area of table and gantry  Ensuring adequate accessibility for all system components and auxiliary equipment to the site

1.2.1 Using Radioactive Isotopes

Since the system involves the use of radioactive isotopes, compliance with Nuclear Regulatory Commission regulations, or similar regulatory requirements (depending on the country), must be adhered to and all permissions obtained well in advance. It is recommended that regulatory compliance is arranged early in the site planning process.

It is essential that all preparations are completed so that required source materials can be obtained prior to installation, including calibration sources. Take into consideration that these sources may have fairly long delivery lead times, yet may also have a short half life, so that it may not be advisable to store them over long periods of time.

General System Requirements 1.3 Delivery Requirements

CAUTION

1.2.2 Project Coordination

The site project coordinator is the primary contact and liaison between GE Healthcare and all siterelated functions, including the purchaser, the construction planners, architects and contractors, and other site administrative personnel.

To insure a successful installation, it recommended that the site nominates a single site project coordinator, preferably a person familiar with similar medical construction projects, manages the entire project. Ideally, the project coordinator is involved in every phase from pre-installation and installation, from conceptual planning through to system start up, working closely with GE Healthcare to ensure that the client upholds all requirements in this

1.3 Delivery Requirements

The system is packed for shipment with minimum tear-down of components.

The system components are sensitive to excessive mishandling, including dropping, shock, vibration, tipping or hoisting. Vibration damage to components may not be evident until after system installation is complete.

 The system components must never be dropped. A drop from a height greater than 1 cm (½") may

induce structural damage to the frame or other major components.

 To avoid damage to sensitive components, dock-to-dock shipment is recommended. Other methods

are acceptable, provided the system is not dropped or otherwise mishandled.

General System Requirements 1.3 Delivery Requirements

1.3.1 General Transportation and Delivery Precautions

1.3.1.1 General Temperature Precautions

Extreme temperatures must be avoided during system transportation and delivery. Ensure that the system is not exposed, for an extended period of time, to temperatures or humidity outside the following specifications.

 Temperature range: -34ºC to +60ºC (-29ºF/+140ºF)  Humidity range (non-condensing): 5% to 95%

NOTE

Component freezing occurs if the system is exposed to temperatures below -18ºC (0ºF) for a period of longer than two days. Allow a minimum of 12 hours for the system to adjust to ambient room temperature, prior to installation.

General System Requirements 1.3 Delivery Requirements

CAUTION

1.3.1 General Transportation and Delivery Precautions

1.3.1.2 Detector Head Precautions

 Detector heads are very fragile and must always be handled with extra care.  Detector heads are extremely sensitive to temperature gradients (sudden changes in temperature).

Failing to comply with the following instructions could cause irreversible damage to the detector heads.

The detector heads must be transported in their original packages, which are designed to provide good mechanical stabilization as well as a certain amount of thermal insulation.

 As soon as the detector heads are unloaded from the transportation vehicles, they must be

moved to a temperature-controlled area while still in their original containers, until they are ready to be installed into the system.

IMPORTANT

The conveyance path from the unloading area to the temperature-controlled area must be wide enough to allow passage of the detector heads packed in the original containers.

 If the temperature in the storage or installation areas differs from that of the delivery route

and/or ambient temperature, a stabilization period of 1 hour per 3°C (5.4°F) difference must be allowed.
