This switch controls the power to the whole processor. '0' is 'off', '1' is 'on'. (Netz is German for 'power.')
This switch turns the rotation motor on and sets the speed. '0' is 'off.' The 'F' through '7' settings adjust the rotation speed from about 25 R.P.M. to about 80 R.P.M. (The normally recommended rotation speed is 'P' at approximately 75 R.P.M. with 1500, 2500, and 2800 series, and '4' at approximately 50 R.P.M. with the 3000 series tanks or drums.)
This mechanism controls the automatic reversal of rotation during processing. It will reverse rotation direction every two revolutions. Turn the fingers away from the magnet coupling (or cog gear, if using JOBO Lift) to provide rotation in one direction only. (Almost all processes are best done with reversal of rotation.)
This switch activates the water bath pump and the heating control circuit. The processor will not heat if this control is off.
This recessed white button resets the thermal overload circuit breaker. The overload automatically turns off the heating element in cases of overheating, such as heating without a sufficient level of water in the processor. Pressing the button with a blunt, non-conducting object (after the heating element has cooled) will reset the circuit. Even when it has tripped, it will not protrude from the side of the processor.
Temperature Control Dials (CPP-2 only)
These dials are used to select the desired operating temperature. The left dial sets 'tens' of degrees, the middle dial sets 'individual' or 'unit' degrees, and the right dial sets 'tenths' of a degree Celsius (C).
Digital Temperature Display (CPP-2 only)
The LED display indicates the actual temperature (in degrees C) of the processor water bath. The display has two illumination levels that automatically switch from bright in room light, to dim in low light (or safelight).
Temperature Control Dial (CPA-2 only)
This dial is used to select the desired operating temperature (in degrees C). (Although the thermostat will maintain the temperature within ± 0.2º C once set, it is not unusual for the dial itself to be off by ± 2.0º C.)
Heater Indicator Lamp (CPA-2 only)
This light is illuminated when the heating element is in operation. It goes off when the water bath has reached its set temperature.
Thermometer Holder (CPA-2 only)
This clip holds the Color Thermometer (#3321) for monitoring water bath temperature.
The CPA-2 and the CPP-2 Processors come with four 260 ml graduates, located in the tempering bath. These graduates are used to pre-measure chemical solutions before or during a process. They also can be used to temper rinse water. The graduates lock into place with a 'bayonet' (insert and turn) type fixture to prevent them from floating. Six 1000 ml bottles for storing and tempering processing chemicals or rinse water also come with the processor. These bottles are placed in the six bottle openings. To prevent the bottles from floating, push down and tilt them toward the front side of the processor. Lock the front shoulders of the bottles under the bottle frame.
This magnet couples with the magnet on the bottom of a JOBO tank or drum. The coupling provides rotary agitation for the tank or drum. (If you are using the JOBO Lift accessory, see 'Processing Using the JOBO Lift'.)
This cluster of parts serves as a support point for the tanks or drums during processing. It is placed at various distances from the magnet coupling (or cog gear, if using JOBO Lift), depending on the length of the tank or drum. It is attached on the raised ridge molded in the tempering bath trough. The roller block assembly is also adjustable in height, to accommodate the drum or tank series being used.
Tempering Bath (Also called Water Bath)
The lower trough (black) tempers the bottles and graduates. Tanks or drums being used for processing are tempered in the upper (red) trough or 'tempering bath'.
Rotate this dial to change the level of water in the upper trough. The numbers on the dial may be used for reference on later resets of the dial.
This drain allows emptying the processor of water for transportation and storage. Do not run the processor without a sufficient level of water in the trough. To route the drain discharge to another location, connect a 5/8" (16 mm) inside diameter flexible hose to the end of the drain. Keep all the hose below the lower trough for proper draining.
Cold Water Solenoid and Overflow Elbow (CPP-2 Only)
The solenoid has a brass adapter for a standard 3/4" washing machine hose connection to a cold water supply. This solenoid allows the processor to be rapidly cooled when changing to a lower temperature process, or to run a process at below room temperature. There is a thirty-second delay before the solenoid activates. The elbow is used to keep the processor from overfilling when using the cooling system. You do not have to hook up the cold water solenoid. However, if you do, the overflow must be allowed to drain. To route the elbow discharge to another location, connect a 3/4" (19 mm) inside diameter flexible hose to the end of the elbow. Keep all the hose below the lower trough for proper draining.
