Operation
a. Placing washer in operation.
(1) Drain hypo from prints before washing them to decrease washing time.
(2) Close the drain valve (figure 32).
(3) Open the water shutoff valve (figure 32) and allow the tank to
fill to overflow. Leave the valve from onehalf to threequarters open to
maintain a continuous flow of fresh water.
(4) Raise the cylinder by stepping on the foot pedal (figure 31).
Engage the pedal lock to hold the foot pedal down.
(5) Rotate the cylinder by hand until the door is on top and the index
pin on each lift channel engages the cylinder to hold it in place.
(6) Release the door locks and open the door.
(7) Place the prints in the cylinder, one by one, so that they do not
stick together.
(8) Close and lock the door.
(9) To lower the cylinder in the tank, step on the foot pedal to release
the pedal lock, and allow the pedal to rise slowly.
(10) Turn on the power switch to start the motor.
NOTE:
No other equipment is used with the washer as part of the washing
operation.
b. Washing time.
Variations in chemical characteristics, temperature, and rate of
flow of wash water, as well as variation in the size and weight of prints,
make it impractical to give firm rules for the washing time required.
Length of washing time should be determined when the equipment is first
placed in
