SECTION 4

Water and Drain Requirements

Water Supply
NOTE
If the upper limit of the water supply temperature to the processor is exceeded, the developer temperature may not be controlled correctly. A water chiller may be required.
a. Processor Supply
(1) Temperature: 4° to 32°C (40° to 90°F) (2) Pressure: 172.35 to 448.11 kPa (25 to 65 psi) Install regulator if required. (3) Volume: Controlled within the processor to 5.7 L/min. (1.5 gal/min.)
(4) Filtration: A 50-micron filter is required. b. Water service must comply with local codes. c. Tempered water service is suggested for processor cleaning and for mixing chemicals manually. d. A molded adapter and washer are provided to adapt the processor garden hose fitting to the 1/2 in. N.P.T.
(male).
Drain
• Capacity: 15 L/min. (4 gal/min.)
• Connection: Open drain; avoid solid connection
Do not use brass or copper for the drain lines. Drain service must comply with local codes.
NOTE
1-6 246628
Environmental Requirements
Room Temperature-Ambient
• Temperature: 15° to 30°C (59° to 86°F)
• Humidity: 15% to 76%
If the upper limit of the room ambient temperature is exceeded, the developer temperature may not be controlled correctly. A water chiller may be required.
Air and Heat
a. Air Exhaust (full load)
(1) Volume: 1.9 m3/min. (65 ft3/min.)
(2) Temperature: 66°C (150°F) maximum
(3) Moisture>300 gr/min. or 121 gr/kg (55 gr/lb) of air b. Heat load to room: 4220 kJ/hr (4000 Btu/hr)
SECTION 5
NOTE
To protect the processor and equipment directly interfaced with the processor, the dryer must be vented according to the following specifications. Failure to properly vent the dryer exhaust can cause corrosion within the processor and interfaced equipment. In addition, the probability of processor-related film artifacts is increased.
[1] The processor exhaust duct must be connected to the building exhaust ducting system. Disposal of
effluent air must comply with prevailing environmental codes.
[2] Use Table 4 to determine the proper amount of negative air within the duct at the end to be connected to
the processor. To prevent venturi effect at the duct opening, all measurements should be made at a point 30.5 cm (12 in.) from the open end of the duct to be attached to the processor.
Compare the average reading with the table below.
Table 4 Static Pressures
Negative Static Pressure, (Water Head)

Adjusting the Tension of the Chain
[1] Check the CHAIN tension after the RACK has
been immersed in solution.
[2] Check that the RACK is at relatively the same
temperature as the solutions in the tanks.
[3] Loosen the 4 HOLDING SCREWS. [4] Hold the RACK assembly above the work
surface. (This will allow the TURNAROUND to move by gravity to the correct CHAIN tension.)
[5] Rotate the DRIVE GEAR one full turn.
Tighten the 2 HOLDING SCREWS on the drive side first.
[6] Set the RACK down on the work surface. [7] Use the ADJUSTING SCREWS. Make the
distance between the RACKS SIDE PLATE and the TURNAROUND SIDE PLATE on the non-drive Side equal to that of the drive side.
[8] Tighten the 2 HOLDING SCREWS on the
non-drive Side.
NOTE
Remove LINKS of the CHAIN as necessary to provide the correct length.
Installing a Chain
[1] To open the CHAIN, insert a SCREWDRIVER
under each open end of the LINK.
[2] Turn the SCREWDRIVER. [3] Install the CROSSBAR of each LINK in the
direction of travel, with the LINKS opening outward. See Figure 11.
[4] Attach the new CHAIN to the existing CHAIN. [5] Pull the existing CHAIN through the RACK
until the new CHAIN is in the correct position.
Figure 11 Adjusting the Tension of the Chain
[6] Disconnect the existing CHAIN from the new
CHAIN.
[7] Fasten the ends of the new CHAIN together. [8] Do the Chain Adjustment above.

Resilient G Roller (Developer and Fixer Racks)
Removing and Replacing the G Roller
[1] Remove the SPRING from both ends on the top of the RACK. See Figures 12 and 13. [2] Remove the SCREWS, WASHERS, GEAR, SPACERS, and BEARINGS from the outside of both SIDE
PLATES.
[3] Rotate the SHAFT so that the KEYWAY is in the up position. See Figure 13. [4] Pull the ROLLER to the non-drive side and remove the KEY from the SPROCKET. [5] Pull the SHAFT to the non-drive side to be free of the SIDE PLATE. [6] Remove the THRUST WASHER, SPROCKET, and SPACER. [7] Continue to pull the SHAFT to the non-drive side. [8] Remove the ROLLER. [9] Reverse the procedure to assemble.
