1428 Standard Washout System
Power Requirement: dedicated 20 amp circuit (110v. 60 Hz)
Dimensions: 20”L x 30”W x 55”H
Weight: 180 lbs

The 1428 Automatic Washout System is "Dual Mode" meaning it can function either as a direct water drain or recycling water mode. Direct drain is recommended for production use.

SETUP & TESTING

1. Unwrap processor and remove from pallet.
2. Install wheels by lifting first one side of processor and installing two wheels ,then repeating the process on the other side
3. Fill tank with warm water by attaching garden hose to the fitting at the top of tank. Disconnect hose after tank is full.
4. Plug the GFCI plug into wall outlet.
5. Place the main power switch in the on position. (note :if the power indicator lamp is not lit it may be necessary to push the "RESET" button on the GFCI)
6. Place the run/pause switch in the run position.
7. Set the timer to H 015 .01/m (this is the correct setting for 5 mil Photomask, some adjustments may be necessary to fine-tune your process.)
8. Place Photomask on drum and affix with magnetic strip.
9. Close drum housing cover 
10. Actuate cycle switch.
11. Remove Photomask at the end of cycle, and blot with blotting towel.

DIRECT WATER DRAIN

Note: Direct water hook-up and drainage is not necessary if re-cycling water.

Required Items:

1.  "Garden Hose" (6-8') Hook Up to Warm Water Supply (95° - 110° F).
   Recommended: industrial (gas) Water Heater with 60 -90 gal min. tank capacity; see the
   Takagi TK1 "on-demand" water heating system at  www.takagi-usa.com.
2. 1½" PVC Drainage Hook-Up
   Recommended: Use flexible 2" hose and hose clamps or plum 1½" PVC piping to drainage hook up. Make sure the unit is free to move around  in order to service rear of machine when needed.
3. Inlet (water) ball valve for On/Off water control:
   Recommended: 4-6' high pressure hose connected to the inlet water hook-up and ball valve. Open the Ball Valve when machine is in operation. Close when not in use. The water hose connected to the inlet hook-up and ball valve will allow the unit to be moved forward and back if necessary. Inside of the holding tank is a water float valve that will stop the inlet water when tank is full. Shutting off the ball valve when not in use will insure there will be no failure to the float valve.

MAINTENANCE:

1. DAILY: Use a mild cleanser on  wash drum and drainage tray.
2. AS NEEDED: Remove and clean the washing nozzles using hard water deposit cleaner and bristle brush. Important: When servicing the washing nozzles, or cleaning a clogged nozzle, remove the nozzle first and blow or rinse the debris free. DO NOT push anything through the orifice as this could result in damage to the spray pattern. DO NOT line up wash nozzles straight; rather keep them in the factory settings (off set one from the other).

RE-CIRCULATION

1.  Fill holding tank with "garden hose" style fitting at the rear of the holding tank (approx. 14 gallons).
   Once filled, the water float valve located inside the holding tank will stop the water from over flowing. Disconnect water hose when tank is full.
   Note: When filling the tank with cool water, the heating time is approximately 90 minutes.
   Always turn on "MAIN" power switch approximately 60 minutes prior to use.
2. Use 1½" PVC cap to cover rear 1½" PVC drain hook-up.
3. Re-direct water flow back into holding tank using (provided) PVC fittings.

MAINTENANCE:

1. DAILY: Clean the water filter screen located in-between the holding tank and water pump. NOT keeping this screen clean compromises consistent water pressure, wash cycles, and will cause the wash nozzles to clog.
      A.  Close inlet (water) ball valve (located between holding tank and water pump).
      B.  Twist filter counter clockwise a quarter  turn to pull filter apart.
2. DAILY: Change the water.
      A.  Close inlet (water) ball valve (located between holding tank and water pump).
      B.  Disconnect supply hose from discharge side (top) of the water pump.
      C.  Connect garden hose, and re-open inlet ball valve.
      D.  Set "TIMER" for approximately 3 minutes (drain time may vary) when holding tank is empty.
            Important: when the water pump tone turns to a high pitch whine, stop the pump with the       
            "PAUSE" OR "POWER" switch. The tank should now be empty.
      E.  Re-connect supply hose with pump discharge
3. DAILY: Add a pool  de-foaming agent  (1-2 capfuls) when re-filling holding tank.
4. DAILY: Use a mild cleanser on  wash drum and drain tray.
5. AS NEEDED: Remove and clean the washing nozzles using hard water deposit cleaner and bristle brush. Important: When servicing the washing nozzles, or cleaning a clogged nozzle, remove the nozzle first and blow or rinse the debris free. DO NOT push anything through the orifice as this could result in damage to the spray pattern. DO NOT line up wash nozzles straight; rather keep them in the factory settings (off set one from the other).

OPERATION

1. The 1428 Automatic Washout System is equipped with a GFCI (Ground Fault Circuit Interrupter) to disconnect power to the unit in the event of a short circuit in the electrical system. When the unit is first plugged in, press "RESET" on the GFCI.
2. Turn pump inlet valve (between tank and water pump) to OPEN.
3. Set the heater thermostat (at rear of holding tank) to 110° - 120° F
4. Turn  "POWER" switch to ON.
   Note: Main POWER switch controls all power functions to unit - including water heating element.
5. Set wash cycle "TIMER." The digital timer has one program setting, with several choices for wash times. (Wash times will vary according to mil thickness of SR2000™ photo resist film).
   Program Settings have five windows.
   They are (from left to right):                  [H]         [hours]         [minutes]        [1/10 of second]        [0.1/m]
                                                                       1                2                     3                              4                          5
   
   Minutes and 1/10 of seconds can be changed by pressing the "+" button to increase and the "-" button to decrease the time.
6. Place SR2000™ across the circumference of the wash drum, dull side up. Use 1/4" of the magnetic strips to secure both sides of film to drum.
7. END OF DAY turn "POWER" switch off.

CONTROL PANEL COMPONENTS

1. POWER switch is ON when indicator light is lit.
2. RUN/PAUSE switch: When in "RUN" mode the unit  will start a cycle. "Pause" the cycle if necessary by pressing the button. "PAUSE" will stop the wash cycle and timer until released into "RUN" mode. To reset the timer to original time, turn POWER switch off and on again.
3. CYCLE switch starts the pre-set timed cycle (two way switch - up or down).
4. TIMER The digital timers indicates the program setting to operate the unit. The proper program setting is H 000 .01/M (000 = hours, minutes, seconds). The timer also indicates (by percentage) the wash time left to a cycle.
5. HAND SPRAYER switch is ON when indicator light is lit. Press thumb trigger to start flow.

At the end of each day, turn "POWER" switch to OFF and close the water inlet Ball Valve. The "Heating Element" inside the water holding tank stays "ON" even when the "POWER" switches are off, the heating element will maintain 90º water temperature. A manual OFF switch and thermostat is located at the rear of the processor.

RECOMMENDED "WASH TIME" SETTINGS

3 mil = H 008 0.1/m
4 mil = H 012 0.1/m
5 mil = H 015 0.1/m
6 mil = H 018 0.1/m

Note: Wash times vary depending upon exposure times and more importantly, the density of the printed image. If necessary, use the attached Hand Sprayer to touch up any areas not completely washed out.
