READ THIS FIRST!

READ THIS FIRST! WARNING Observe the following warnings. Failure to comply may result in personal injury, death, or equipment damage. 1. Shock Hazard: Lethal voltages are present. Use extreme care when servicing equipment with the AC/Mains power connected. Do not leave an open system unattended with the AC/Mains power connected. DISCONNECT THE POWER SUPPLY AND REMOTE CONTROL AC/MAINS POWER CORDS BEFORE REMOVING OR REPLACING COMPONENTS. Make only proper electrical connections. Plug the AC/Mains power cords directly into grounded, hospital-grade for U.S. applications, three-pronged outlets. Do not use extension cords. Do not use an adapter to plug either of the AC/Mains power cords into a two-pronged, non-grounded outlet. Replace any worn or frayed wires immediately. 2. Explosion Hazard: A risk of explosion exists if used in the presence of flammable anesthetics. Never operate the Empower Injector System in the presence of any flammable gases. 3. Equipment Safety: Only connect the Empower Injector System’s Power Supply and Remote Control to electrical sources of the proper voltage and frequency. If an incorrect voltage is used, the Injector system may be damaged when turned on. The Empower Injector System contains electrostatic sensitive components. You must wear a wrist grounding strap and place components on an antistatic pad. Failure to comply may result in damage to the equipment due to electrostatic discharge. 4. Unauthorized Modification and Repairs: Unauthorized modifications to the Empower Injector System will void your warranty. Authorized personnel only should perform servicing of internal parts. Opening or servicing of the Empower Injector System by unauthorized personnel may result in injury, death, or damage to equipment, and will void your warranty.

Section 2: System Description 2.1

SYSTEM CONFIGURATION

The Empower Injector System consists of the following: • • • • •

Injector Remote Control Power Supply Cables and AC/Mains power cords Pendant Switch

The Injector is comprised of the Injector Head and the Injector Controller. Figure 2-2a shows the EmpowerCT Injector System and Figure 2-2b shows the EmpowerCTA Injector System. In both systems, when installed, the Injector and the Remote Control are connected to the Power Supply by a power/communications cable and a communications cable. The power/communications cable to the Injector provides power and communication signals. The communications cable to the Remote Control is for communications only. The Power Supply (see Figure 2-2d) and the Remote Control (see Figure 2-2c) have their own AC/Mains power cords that may be plugged into separate wall receptacles. The Injector and the Remote Control have their own power switches and both must be set to the ON position to have the entire system powered up and operational. The optional Extravasation Detection Accessory (EDA) is provided with the Extravasation Detection Clip and mounting accessories (see Figures 2-2a and 2-2b). The EDA is powered from the Injector. Figure 2-1a provides an illustration of the EmpowerCT Injector System configuration with the EDA. Figure 2-1b provides an illustration of the EmpowerCTA Injector System configuration with the EDA.

MOUNTING SYSTEMS

The Injector and the EDA can be installed using the Injector Floor Stand for floor mounting, (see Figures 2-2a and 2-2b) or the overhead mounting system that uses an Articulating Arm that can be ceiling or wall mounted. A short, medium, or long Ceiling Mount Column is provided for ceiling mounting. Figure 2-3 shows the overhead mounting system that is used for CT and CTA systems. The Remote Control includes a pedestal mount for placement on a desk or other flat surface, or it can be wall mounted. The Power Supply can also be placed on a flat surface or wall mounted.

When troubleshooting, it may become necessary to short pins on the power/communications cable, communications cable, and the Power Supply in order to perform continuity testing. The following jumpers can be easily assembled by the technician and included in the toolkit: 1. Assemble jumper wire (see Figure 2-4a) with two male pins (equivalent: Tyco/Amp P/N 66591-1, male pin – 22-18 AWG). 2. Assemble jumper wire (see Figure 2-4a) with two female sockets (equivalent: Tyco/Amp P/N 66592-1, female socket – 22-18 AWG).

It will also be necessary to have a separate set of Digital Voltmeter test probes with lead pins that are sufficiently small to allow accurate measurements on the power/communications cable and communications cable pins. The test probes can be assembled by the technician and included in the toolkit. 1. If preferred, obtain an alternate set of test leads (equivalent: Radio Shack P/N 278-764). 2. Replace the lead pins with smaller male pins (equivalent: Tyco/Amp P/N 66591-1, male pin – 22-18 AWG). Crimp the pins to the wires and insulate with heat shrink tubing or electrical tape (see Figure 2-4b).

Section 3: Periodic Inspection and Maintenance 3.1

PERIODIC PROCEDURES

Only qualified personnel should perform periodic inspection, maintenance, and service procedures.

3.1.1

Periodic Inspection

Qualified personnel should perform inspection once every twelve months. The Visual Inspection Test (see Section 3.3.1 – Visual Inspection Test), Electrical Safety Test (see Section 3.3.2 – Electrical Safety Test), Field Test Form (see Section 3.3.3 – Field Test Form), and EDA Functional Test (see Section 3.3.4 – EDA Functional Test) should be performed as the periodic inspection. During testing should any part of the Empower Injector System fail inspection, notify ACIST Service Department immediately.

3.1.2

Periodic Maintenance

Maintenance consists of cleaning the Empower Injector System and should be performed on a regular basis or as needed. If it is not used for a prolonged period of time, it should be cleaned at least every six months. Follow the cleaning and storage instructions in Section 3.2 – Cleaning and Storage Procedure.

3.1.3

Service

Preventive maintenance and service must be performed by an authorized technician only who is familiar with the use, operation, and servicing of the Empower Injector System. Unauthorized service may result in personal injury, damage to the system, and voiding of the warranty.

CLEANING AND STORAGE PROCEDURE

After each injection, remove and dispose of the Syringe in accordance with the Empower User’s Manual. The Empower Injector System should be cleaned when the day’s schedule of injections is complete, in the event of accidental spills on the equipment, or as periodic maintenance. Using the following procedure: 1. Turn off power to the Injector. 2. Turn off power to the Remote Control. 3. Unplug the Power Supply’s and Remote Control’s AC/Mains power cords from their respective outlets. 4. Clean as follows: a. For the Injector Controller, Injector Head, and Power Supply: dampen a paper towel with mild, hospital-grade disinfectant and carefully wipe off any dirt or spilled fluids. b. For the Remote Control: Clean the touch screen with a soft towel and mild detergent. 5. Observe the following: a. Do not autoclave. b. Do not use strong disinfectants or cleansers. c. Do not allow liquid cleaner to get inside system components. d. Never submerge system components in water.

WARNING

Failure to observe cleaning instructions may result in equipment damage and create an electrical hazard that can result in personal injury to the technologist and patient.

When not in use, the Empower Injector System should be stored in a safe place that avoids the possibility of spills or other accidental damage. It should be placed in an area away from dust, extreme or quickly changing temperatures.
