Instruction Manual for the ATL's: 2200, 2300, 2400 and 2500
5. Operation
Caution: Perform a trial run with test film before processing any "real" film or paper.
5.1 Water supply
Open the cold and tempered water supply valves feeding the machine.
5.2 Turning on the processor
Switch the processor ON using the ON/OFF button.
The unit starts filling with water within a few seconds, and automatically maintains the correct water bath level.
5.3 Setting the tempered water supply
The temperature of the incoming tempered water must be maintained at the temperature of the process.
Refer to your water panel instructions to set the temperature of the rinse water. JOBO recommends the use of water panel #4189 or #4236 which were specifically designed for the operation of JOBO Autolabs.
5.4 Filling the chemical bottles
Lift the rear lid to access the six in-line bottles (model ATL-2200 does not have rear in-line bottles). Unscrew the bottle caps and pour in your chemistry. The maximum capacity of the bottles is 1 liter each. Do not fill above the air pressure line grommets.
Model ATL-2500 automatically fills the front bank of 1.5-liter bottles with the chemicals stored in the 15-liter bottles below the processor. Model ATL-2400 automatically fills the rear bank of 1-liter bottles from the same 15-liter bottles stored below the processor.
The quantity in the bottles must be entered into the processor's memory as explained in section 7.4. Screw the caps back on to the bottles tightly. If the bottle caps are not tight or cross-threaded too little or no chemistry will be pumped and the film or paper will be improperly developed. (The processor will warn you if no chemicals are pumped on any volume over 140ml.) Make sure the air distribution lines fit snugly into the rubber grommets and the chemical lines are completely on the grey tube coming out of the bottle.

Warning: Do not overfill the bottles. If the bottles are over-filled, chemistry may siphon into the unit. Do not use the top of the AutoLab as a resting place for coffee, chemistry, or any other liquids. If they were to spill, the moisture could damage the electronics.
5.5 Filling the rear storage bottles - Model ATL-2200 only
The ATL-2200 includes six additional 1-liter bottles for pre-tempering chemistry. Lift off the back bottle cover and remove the bottles. Fill the bottles with the chemistry you want to preheat, place them back in the processor, and reposition the bottle cover.
Hint: Write the name of the chemical, who mixed them, and the date they were mixed on the bottles. A grease pencil works well for this.
5.6 Adjusting the water level
On the front, right-hand side of the water trough, there is a sliding panel with a stainless steel screen. Sliding the panel to the left (open) will increase the water drainage and lower the upper trough water level. Sliding it to the right (close) will raise the upper trough water level. Set the water level so the bottom of the drum being used is covered with approximately 1/4" of water.
The water level needs to be changed every time a different tank or drum system is used. If the water level is set too high the tank floats off the rollers, uneven development will occur because the chemistry will pool at one end. If the level is set too low, the tank will not be heated properly.
Clean the stainless steel screen filter as needed. Operating the processor with a clogged filter may cause the water level to be too high. Operating the processor without the filter screen will cause debris to clog the water recirculation pump, and may damage the processor.

5.7 Tank and drum systems
JOBO produces a variety of tanks and drums you can use, depending on the format sizes of your film and paper. JOBO tanks and drums are attached to the processor with a coupler on one side of the rotation trough. The coupler uses a ventilation tube, and a cap. If you are using 1500, 2500, or 2800 series tanks, the cap goes on the top tube and the ventilation piece fits in the lower tube. If you are using the 3000 series drums the cap goes on the bottom tube, and the ventilation tube on the top tube.
Illustration shows cap and ventilation tube positioned for 1500, 2500, or 2800 series operation.
5.8 Setting the roller supports
The positions of the rollers, roller extensions, and bases are illustrated here. Note that the roller with the black O-ring is only used with the 2500 and 2800 series tanks.

5.9 Automatic cooling
The water bath is cooled automatically until the correct developing temperature is reached. When the water bath temperature rises higher than the selected process temperature the cold water solenoid opens to let in cold water. The cold water solenoid opens approximately 30 seconds after the water bath temperature has exceeded the processing temperature.
If your cold water supply is warmer than the selected process temperature, you will have to purchase a water chiller. Contact your plumber or local photographic dealer for more information.
Hint: If you want to cool the processing temperature from a high level to a low level you should turn off the machine, drain the water bath, turn on the machine, and select the new process. This procedure will save time and water.
5.10 Collection of used chemistry
Depending on the model of processor you purchased, you have a variety of reclamation options. With all four models, you can collect the chemicals in six 1-liter bottles located at the front of the processor. Models ATL-2400/2500 also allow you to reclaim the chemicals in six 15-liter bottles located beneath the processor. The same 15-liter chemical reclamation for models ATL-2200/2300 is accomplished by purchasing the ATL Support Table #4221 and Chemical Collection Cart #4225.
Note: Model ATL-2500 ships with six 1-liter reclamation bottles but has a maximum pumping capacity of 1.5 liters. When assembling the ATL-2500 you must replace the front six 1-liter bottles with special "funnel" type bottles included with the processor. This will allow the chemicals to pass through the front bottles into the six 15-liter bottles stored below.
Your AutoLab can be configured to reclaim certain chemical steps, and route others to the drain. This setting is accomplished by limiting the movement of the internal drain arm located on the left side of the processor. Two black, mushroom shaped caps (#16247) are included with the processor. The caps are designed to limit the movement of the drain arm when they're placed in the drain holes.The six holes in the drain area connect to openings over the six bottles recessed in the front of the processor. The black drain arm moves in conjunction with the process steps from back to front. The rinse steps are drained between the holes.
The following table illustrates the different cap formations you can specify:
Which bottle(s) to reclaim Which hole to cap Position of drain arm None One cap on 6 In front of cap All No caps N/A 1 One cap on 2 Behind cap 1-2 One cap on 3 Behind cap 1-3 One cap on 4 Behind cap 1-4 One cap on 5 Behind cap 1-5 One cap on 6 Behind cap 2 Caps on 1 and 3 Between caps 2-3 Caps on 1 and 4 Between caps 2-4 Caps on 1 and 5 Between caps 2-5 Caps on 1 and 6 Between caps 2-6 One cap on 1 In front of cap 3 Caps on 2 and 4 Between caps 3-4 Caps on 2 and 5 Between caps 3-5 Caps on 2 and 6 Between caps 3-6 One cap on 2 In front of cap 4 Caps on 3 and 5 Between caps 4-5 Caps on 3 and 6 Between caps 4-6 One cap on 3 In front of cap 5 Caps on 4 and 6 Between caps 5-6 One cap on 4 In front of cap 6 One cap on 5 In front of cap Note: Government regulations can affect your right to put photo chemistry into your drains. Consult the proper authorities for any regulations before draining your chemistry.
5.11 Installing the auto-refill hoses
On models ATL-2400/2500 you have the option of having a bank of bottles filled with an automatic system designed to allow you to process multiple runs of film more quickly (model ATL-2400 fills the rear bank of 1-liter bottles, model ATL-2500 fills the front bank of 1.5-liter bottles). There are six hoses connected to the refill pumps on the right side of the rear of the processor. Route these hoses to the six 15-liter bottles stored below the processor (through the holes in the bottles) then fill the bottles with chemicals. The bottles come with floating lids to prevent oxidation.
It is important that the lids of the bottles be partially unscrewed to allow chemicals to be pumped from them. Do not remove the lids completely or the chemicals will oxidize more rapidly and it will be possible for dust to enter the bottles.
When the processor is in RUN mode, if a program is selected using the front or rear bottles (depending on the model), and the bottles are not full of chemicals, the refill pumps will run. It does not hurt the pumps to run dry temporarily. Use the following positions for the chemicals (so it's the same as the chemical collection bottles to the left).
