Fuji Hunt DIS (Direct Injection System)

Operation Manual
1. Description
Noritsu and Gretag minilabs which are designed for Kodak SM chemicals do not have conventional replenishing
tanks. Conventional replenishing tanks contain (a) concentrate(s) diluted with the proper amount of water.
The Kodak SM chemical kits for film and paper are used as disposable replenishment tanks containing
concentrates only. These concentrates are dosed directly into the working tanks. The necessary amount of water
is dosed separately and is injected directly to the working tanks.
The Fuji Hunt DIS chemical system consists of external replenishing tanks that can be refilled with the
corresponding Fuji Hunt concentrates/ready-to-use chemicals. Only four external replenishing tanks are needed
for each process (film and paper).
When converting from Kodak SM chemicals to the Fuji Hunt DIS chemical system, a few simple manipulations
in the minilab hard- and software need to be performed (for more details see section on installation) :



Rearrange the tubing for the connection with the Fuji Hunt external replenishing tanks
Modify the replenishing rate settings both for the chemical concentrates as for the water additions

2. Process Conditions
Film processing
Film processors designed for the Kodak SM chemistry use the standard C41-RA process. Following table

The Fuji Hunt C41 DIS Developer Replenisher is a ready-to-use solution, therefore no additional water needs to
be replenished.

Paper processing
The paper processors designed for Kodak SM chemistry use the RA-2 process. Following table contains the

Note :
The mentioned replenishing rates are to be used as a starting point. Replenishment rates can vary depending on
factors such as : paper/film type, exposure level, agitation, carry-over, production volume etc….
Adjust the replenishment rate of the developer according to the results of the control strip readings.

4. Fuji Hunt external replenishing tanks
Two systems are available :

Stand-alone unit (see picture below) :The replenishing tanks for both the film and the paper chemicals are
attached on a stand. The stand is equipped with mounting hooks for easy attaching and detaching of the
replenisher tank holders. Only one external power supply is needed for all units. The stand-alone unit is used
when there is not enough available space on the processor to attach the individual units, e.g. Noritsu 2511. A
single DIS tank unit can be used on the stand where (for example) only a film processor is to be converted from
SM to the DIS system.

Individual units : when sufficient space on the processors is available e.g. Noritsu 2611 and V100, the film
and paper rep tank units can be attached directly on the outside frame of the minilab. Holes need to be drilled to
attach the mounting hooks (see picture below)

Film rep tank unit (see picture below) :

Paper rep tank unit (see picture below) :

All replenishing tanks (N1, N2, N3, N4, P1, P2A, P2B & P3) are equipped with level sensor and a LED
indicator. When a replenishing tank runs empty, an alarm signal sounds and the corresponding LED indicator
turns on.

6. Installation procedure
As the Kodak SM chemical packs are removed, the following alarms need to be switched off through the
program menu : REPLENISHER ERROR and REPLENISHER PACKAGE. A service diskette is needed to
enter this program menu. For the Noritsu 2511 & 2611 a service diskette is available from STS (Sales and
Technical Service) at Fuji Hunt N.V.
To connect the outlets from the DIS holding tanks to the corresponding replenishing pumps, PVC tubing with an
ID 4mm /OD 6mm is required.
One can connect the tubes (PET 4 mm ID / 6 mm OD) directly to the pump inlet or to the filter inlet, which is
located before the pump inlet. The second option is to be preferred.
For the Noritsu 2511 only one of the 3 available developer replenishing pumps is needed.
Set the replenisher volumes to the recommended values. For the developer pumps, which are not used, the
corresponding setting is 0,01. (The program doesn’t accept 0,00)
In order to prevent oxidation/evaporation/crystallisation, floating ‘lids’ must be installed in all DIS holding
tanks. Floating lids in RA4 DIS holding tank must have a round shape (ball-type) with a minimum diameter of
maximum 20 mm.
After filling the holding tanks with the appropriate concentrate, bleed the lines free from air. Check the pump
output.
A typical conversion for a Noritsu V50SM C41 film processor will appear as follows :

Removing the front panel from the processor replenisher section reveals the replenisher pumps. To avoid any
“no box” alarms, it is normal to leave to old (empty) Kodak SM boxes in place in the processor, as shown above.
In the example here, there is not enough space to attach the DIS unit directly to the processor, so it is placed on a
stand in a convenient location – here at the end of the V50 :

The replenisher pipes can be seen emerging from the bottom of the DIS unit. These are connected directly to the
(white) filter inlets that can be seen on the picture below :

For the Noritsu V50SM (and similar SM machines), the original F1 Film Box contains a three-part developer.
As you are using pre-mixed DIS N1 replenisher (one single part) to feed the replenishment unit, you will need to
spilt the developer replenisher feed into three pipes by using two Y-connectors for standard (non-LR) developer.
When setting the replenishments rates, it is probably easiest to set the same replenishment rate on each of the
three developer concentrate pumps when using standard replenishment rate Fuji Hunt EnviroNeg Developer
Replenisher AC chemistry. By doing this there is enough adjustment in the pumps that you won’t have a
problem.
The replenisher pumps for other three baths – formerly fed from the F2 Film Box – are simply connected to the
DIS unit. Connect the appropriate DIS replenisher pipe to the correct filter inlets on the processor (in place of
the existing pipework to the SM boxes).
Having modified the pipework, you must now update the software for the processor. The same modified
software is suitable for all Noritsu VxxSM processors. Insert the supplied floppy disc into the slot at the front of
the processor, just below the film cassette collection bin :

Enter the Noritsu menu system, and scroll down until you reach the FLOPPY/STANDARD SETTING menu :

Selecting Yes will update the Noritsu software and deactivate the SM “box empty” error messages. Once you
have bled the new replenisher lines and checked the pump outputs, the conversion procedure will be complete.

8. Chemical Handling
All photographic processing solutions when brought into contact with human tissue can be harmful depending on
the nature of the solution and concentration. All users of such solutions should therefore exercise the greatest
care to avoid the chemicals contacting the skin, eyes or other parts of the body. Always wear solution resistant
gloves and goggles. Since some photographic solutions produce irritating vapours, adequate ventilation is
necessary.
Always read the hazard information provided on the packs of all products before attempting to handle the
solutions. Material safety data sheets are available in several languages for all photographic products.
In case of accidental contact with processing solutions, wash the affected part with plenty of clean cold running
water. Wash with an acidic soap and rinse thoroughly with water. Consult a medical doctor.
