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.
