GENERAL INSTRUCTIONS

(INSTALLATION)

REFER TO SPECIFICATION SECTION FOR FURTHER DETAILS.

Note: Read the following instructions carefully. Proper installation of your Jackson

Dishwasher will assure proper machine operation.

Uncrating 24:

1. Remove wooden blocks from carton.

2. Slide carton sleeve upward over top of dishwasher, set to one side.

3. Remove bolts holding wooden base to machine and screw in adjustable feet supplied. (Feet are

inside of dishwasher.)

4. Set dishwasher in place, ready for installation

Note: NSF base cradle must be field installed on all 'F' and 'P' models. Cradle goes under

machine and must be sealed in place using silicone sealant.

Installation Instructions:

1. The dishwasher can be leveled to the proper height by adjusting the feet on the four corners. The

front of the unit must be 1/4"to 1/2"higher than the back.

2. Refer to the dimensional data sketch for connections.

3. The drain from the machine is a GRAVITY DRAIN SYSTEM and should have the proper drop from

the machine to an open floor drain, vented to atmosphere. The drain connection is located to the left

rear of the machine when facing the machine's door. The drain fitting is I 1/2" OD tube size, 7" from

floor.

4. IMPORTANT —PLEASE READ —Located on the back upper left corner of the unit is a steam

equalizing vent. This vent in no way should be blocked or prevented from allowing steam to be

vented to the outside of the unit or from under the cabinet in which the unit is installed. Never pipe

the steam downward toward the floor. (SEE PAGE 5 IF IT IS BEING INSTALLED UNDER A

COUNTER.)

5. The electrical connections should be made to the terminal board located at the center front. The

terminals are marked L1, L2, and Neutral. Install proper circuit breaker and conduit size to conform

with local and/or national codes (standards). USE COPPER WIRE ONLY (#8 AWG).

Installation of Top and Sides on 'F' and 'P' Models:

1. Insert rear barrier with angle facing out. Install prior to placing top on uit.

2. Place top on unit, making sure front lip is under flange, but does not interfere with latch or switch

mechanism. Place studs in holes on back of unit. Use 1/4-20 nuts.

NOTE: For 'P' models, omit steps 1 and 2.

3. Remove kickplate. Open door and place side panel lip at door opening. Work panel under top by

pushing with palm of hand. Put self-tapping screws in four places. Both side panels are installed in the

same way. Note: If unit being installed is an 'F' model, do not put the bottom rear self-tapping screw in

each panel until step 4.

4. 'F' models require a back panel. For installation, slide back panel behind lip of side panels and secure

with the two remaining self-tapping screws.

Installation of Model 24 Top and Table gasket:

These instructions are to be used for applying the adhesive backed sponge rubber strip to the top of the

machine prior to setting the table in place.

Included with the Model 24 table is a 6 foot length of 1/4"thick x1" wide sponge rubber adhesive backed

stripping.

Instructions for applying gasket:

1. Place one end of the stripping along the complete

side of the leg support flange and cut it off.

2. Repeat the same procedure along the other side.

3. Place the remaining piece along the front edge, fit it

in between the side pieces and cut it to length.

4. Remove the backing and set the strips in place.

Instructions for installation under a porous

counter top:

1. If possible, a hole should be cut through the counter

top directly above the equalizing vent. A piece of 1

1/4"OD pipe is then inserted through the hole into the

vent opening and piped to the outside.

2. If cutting a hole in the counter is not possible, then a

piece of stainless steel 36" wide by 36" long bend in

the middle at 90 should be centered directly over the

vent to allow the steam to condense on it when it

comes out of the vent.

3. It is very important that this vent be kept open and

cool air allowed to circulate around the unit.

Installation of Model 24 Dishwasher Under Dishtable:

1. On the end of the table, locate bracket #4 opposite the sink end.

2. A square rubber gasket #3 is supplied and should be secured to top frame of dishwasher with

caulk or suitable adhesive.

3. Place dishtable #2 where it is to be installed and support the machine's end.

4. Slide dishwasher #1 underneath dishtable #2 so that the outside of machine is positioned against

the guide bracket #4. Make sure dishtable and dishwasher are in desired permanent location.

5. Using the two holes in bracket #4 as a guide, drill two holes 9/64"diameter in the side panel of

machine. Note: Drill through first thickness of metal only.

6. Using the self-tapping screws supplied, screw them through bracket #4 and into the side panel of

machine until screws are tight.

Removal of Pan Strainer for Cleaning: (Wash and rinse head assemblies must be removed prior to

removing strainer.)

1. Turn machine off and drain by depressing drain switch and releasing.

2. Remove holding pin from rinse feed pipe, remove rinse head assembly by pulling forward.
