Purpose

This document provides the instructions necessary to perform repair and maintenance of the

AT2000 XR Automatic Film Processor. It is intended for all recognizable field servicing of the

unit and includes procedures to disassemble the unit to access internal components as well

as steps necessary to perform preventive maintenance, inspection, cleaning, troubleshooting

and removal/replacement of defective parts.

This manual is not intended for the routine use of the AT2000 XR Film Processor. Refer to

the Operator's Manual shipped with the product for all processor operation. It is further

understood that repair and maintenance information provided herein is to be performed by a

trained servicing technician.

Power Removal

Prior to performing the procedures contained in this document, turn off power switch by placing

the rocker switch on the top of the unit to the OFF (0) position. Also disconnect the line cord

from the wall outlet and the communication cable from the Scanner.

Warnings and Caution Statements

In these instructions, the following definitions Apply for all WARNINGS and CAUTION

Statements:

Warnings: Any operation, procedure or practice, which, if not strictly observed, may result in injury

or long term health hazards to personnel or patients.

CAUTIONS: Any operation, procedure or practice, which, if not strictly observed, may result in

destruction of equipment or loss of treatment effectiveness.

Task Guidelines

Personnel performing maintenance and repair tasks contained in this manual should follow

standard industry guidelines for working on electronic equipment as necessary. These

include the following:

qAlways use a clean well-lit work area with ample space required for the size of the job.

qAlways make sure to protect finished surfaces from scratches or other damage by

using cushioning material such as a soft cloth or packaging material between the

finished surfaces and the area that may cause damage.

qKeep all attaching hardware and fastening screws together with the associated

removed assembly. If necessary use separate storage containers or envelopes for

each hardware group.

qPrior to removing any part or assembly, note location and orientation of assemblies

being removed.

qTag wires and associated mating connectors before disconnecting.

qUse care when disconnecting mating connectors so as not to damage the connector

keys and connection to the associated printed circuit board, wire or cable.

qBe aware of the damage impact of electrostatic discharge (ESD) on electronic devices

and use ESD precautions when handling printed circuit boards and wiring comprising

the Scanner.

ELECTRICAL 115VAC, 60 Hz, 8 AMPS. Use a 15 AMP, 3 prong, grounded out-

let. A separate dedicated 15 AMP line is recommended.

WATER FLOW 1/2 gallon per minute water flow (while processing film).

WATER PRESSURE 80 PSI maximum / 30 PSI minimum. Water source must have a

manual shut-off near processor.

WATER CONNECTION Valved 3/4" male garden hose fitting near rear of processor. 6'

hose with standard female garden hose fittings provided.

WATER BACKFLOW

PREVENTION

A vacuum breaker is not normally required because the proces-

sor has a 1" air gap between water supply inlet and the maximum

possible water level height.

WATER TEMP 55° F (13° C) to 80° F (27° C)

DRAIN 1-1/2" vertical PVC standpipe, open at top. DO NOT DRAIN INTO

COPPER OR BRASS. The top of the standpipe must be 6" below

the bottom of the countertop.

DIMENSIONS 18" (H) x 15" (W) x 25" (D) with leveling base.

WEIGHT 90 lbs. with water and chemistry (75 lbs. empty).

VENTILATION Room air temperature must be below 80° F (27° C), during pro-

cessing. Because heat is generated during processing, adequate

ventilation is required to maintain darkroom temperature. 8 - 12

volume room air changes per hour.

PLUMBING CONNECTIONS

CONNECT TO PLUMBING

(See Plumbing Connections - OPTIONS 1 & 2)

qMatch color-coded drain hoses to corresponding color-coded label on barbed fittings

at the rear of the unit. Mount the hose end onto the barbed fitting by rotating the hose

clockwise while pushing. Push the hose flush up against the barbed fitting, leaving no

space. If removal of the hose is necessary, rotate clockwise while pulling the hose. No

clamps are required as the hose is self clamping.

qIf routing the drain lines, replenishment lines and water inlet hose through the counter-

top, drill a 2-1/2" diameter hole through the countertop (See Plumbing Connection

illustrations). For routing replenishment lines through the counter, unscrew the retain-

ing nut under cap to remove the cap assembly. Cut the replenishment lines to appro-

priate length.

OPTION 1: Route water (white) drain hose to a vertical 1-1/2" PVC standpipe. Route

Developer (black) and Fixer (red) drain hoses to chemistry recovery con-

tainers under the counter.

OPTION 2: Route all three drain hoses into a vertical 1-1/2" PVC standpipe.

NOTE: Hoses must always slope downward to drain pipe or recovery containers without any "U's"

or upward bends in the hose.

Hoses routed into the drain pipe must be cut so that the ends are at a min. 6" above the

standing water in the P-trap at the bottom of the pipe.

Hoses routed into the chemistry recovery containers must be cut so that the ends are 2"

above the highest expected solution level in the recovery container.

qChemistry recovery & replenishment bottles must be placed below the processor or

under the counter.

REPLENISHER BOTTLES CANNOT BE ABOVE THE PROCESSOR.

WATER RECIRCULATION OPTION

PLUMBING CONNECTIONS

1. Fill the container with fresh water to the bottom of the WATER label.

2. Cut the wash water drain hose so that when it is inserted into the water container it reaches

to the bottom of the WATER label. Insert the hose into the container.

3. Insert the wash water inlet hose all the way to the bottom of the water container. See the

illustration below for the correct installation.

WARNING: THIS PLUMBING CONFIGURATION CANNOT BE CONNECTED TO A FRESH

WATER SUPPLY LINE.
