INSTALLATION INSTRUCTIONS
NOTE: Before any connections are made, visually check the
entire machine for any possible shipping damage. If any damage
is found, proceed to “CONCEALED DAMAGE OR MISSING
PARTS”.
UNPACKING THE DISHWASHER:
STEPS:
1. Remove all protective packing material from machine.
2. Place machine in its operating location and remove skid.
3. Adjust all four (4) adjustable bullet (or flanged) feet so contact
is made to floor.
For proper operation, the dishmachine should be leveled from
side to side and from front to back. Using a level placed on the
flat area at top of unit, adjust leveling feet up or down.
NOTE: The dishwasher must be positioned and leveled before
making any connections to the unit.
CONCEALED DAMAGE OR MISSING PARTS:
IMPORTANT: FOR YOUR PROTECTION, PLEASE READ AND
OBSERVE THE FOLLOWING:
This dishwasher has been thoroughly inspected and carefully
packed before leaving our warehouse.
Any valves fouled by foreign matter, and any expenses
resulting from this fouling, are not the responsibility of the
manufacturer.
DRAIN LINE CONNECTION:
The drain for the Conserver 24LT/Conserver 24LTP dishmachine
is a pumped discharge. This unit comes with a drain hose which
should be connected to a system drain. It is recommended that
the drain hose be used as opposed to hard or permanent drain
piping.
Ensure that the drain connection has an airgap (indirect) to allow
proper draining.
The drain height should not exceed 24” above floor height.
Ensure that this unit is installed in accordance with all applicable
codes.
If a grease trap is required by code, it should have a flow capaci-
ty of 5 gallons per minute.
WATER SUPPLY CONNECTION:
Install the water supply line (1/2” pipe size minimum) to the dishmachine line strainer using copper pipe. It is recommended that
a water shut-off valve be installed in the water line between the
main supply and machine to allow access for service. The water
supply line is to be capable of 20 PSI “flow” pressure at a recommended temperature of 140°F (minimum of 120° F required).
Concealed loss or damage means loss or damage which does not
become apparent until the dishwasher has been unpacked. The
contents may be damaged in transit due to rough handling even
though the carton may not show external damage.
If it is found that the shipment has concealed damage, PLEASE
DO NOT RETURN IT TO JACKSON, but notify the carrier (within
48 hours) asking them to send their agent to fill out an inspection
report. Save the cartons so he may inspect them and be sure to
note in the report any black marks, creases, tears, crushed corners or any other marks indicating rough handling. Also, notify the
JACKSON dealer immediately.
If it is discovered that there are missing parts such as: strainers,
spray assemblies, rinse assembly, owner’s manual or racks,
please notify JACKSON immediately.
PLUMBING:
NOTE: ALL CONNECTIONS MUST COMPLY WITH ALL
APPLICABLE LOCAL, STATE AND NATIONAL PLUMBING
CODES.
The plumber is responsible for ensuring that the water line is
THOROUGHLY FLUSHED BEFORE connecting it to any manual
or solenoid valve. It is necessary to remove all foreign matter
such as chips (resulting from cutting or threading pipes), pipe joint
compound or, if soldered fittings are used, bits of solder or cuttings
from the lines. This debris, if not removed, may lodge in the
valves and render them inoperative.
In areas where the water pressure fluctuates or is greater than the
recommended pressure a water pressure regulator valve must be
installed. This item should be located before the “Y”-strainer and
after the shut-off valve.
Do not confuse static pressure with flow pressure. Static pressure
is the line pressure with no flow (all valves and services are
closed). Flow pressure is the pressure in the fill line when the fill
valve is open and the machine is in the fill cycle.
It is recommended a shock absorber (not supplied) be installed in
the incoming water line. This prevents line hammer (hydraulic
shock), induced by the solenoid valve as it operates, from causing
damage to the equipment.

ELECTRICAL
WARNING: Electrical and grounding connections must comply with applicable portions of the National Electrical Code
ANSI / NFPA 70 (latest edition) and/or other electrical codes.
WARNING: Disconnect electrical power supply and place a tag or lock at the disconnect switch to indicate that you are
working on the circuit.
ELECTRICAL POWER CONNECTION:
This dishmachine comes with a standard 3 prong 120V outlet power cord attached. Prior to plugging the unit into the outlet, have an
electrician verify that the incoming power is at the proper voltage and to further verify L1 and N to ground individually.
Prior to installation, verify that the electrical service agrees with the specifications on the machine data plate located on the right side
and to the front of the machine. Refer to the data plate for machine operating requirements, machine voltage, total amperage load and
serial number.
VOLTAGE CONNECTIONS:
STEPS:
1. Place machine’s POWER SWITCH into the off position.
2. Apply power to the dishmachine.
3. Check incoming power at power block for proper voltage per the data plate.
4. Turn off power at service breaker. Mark breaker for dishmachine and advise the proper personnel.
DO NOT APPLY POWER OR TURN MACHINE ON AT THIS TIME. ALL PLUMBING AND WATER CONNECTIONS MUST BE COM PLETED BEFORE MACHINE CAN BE OPERATED.

CHEMICAL DISPENSING EQUIPMENT
The Conserver 24LT dishmachine is not supplied with integral chemical dispensing peri-pumps. Instead, an independent chemical dispensing system must be connected to the unit prior to use in order to achieve required cleanliness and sanitation. Please consult the
literature that accompanied your independent chemical dispensing system for information concerning installation and operation of the
dispenser.
The Conserver 24LT requires that a separate chemical feeder be connected to it to provide the required sanitizer. This feeder
needs to be able to provide 2.271 ml of a 10% Chlorine sanitizer for every machine cycle.
Chemical feeder dispensing tubes are fed into the Conserver 24LT through the white bulkhead fitting in the back lower por tion of the unit.
WARNING: CHLORINE-BASED SANITIZERS CAN BE DETRIMENTAL TO YOUR MACHINE IF THE CHEMICAL SOLUTION IS
TOO STRONG. SEE YOUR CHEMICAL PROFESSIONAL TO ENSURE YOUR DISPENSER IS SET UP CORRECTLY.
TO PREPARE PUMPS FOR OPERATION
The Conserver 24LTP dishmachine is supplied with detergent, rinse additive and santizer dispensing peri-pumps. Locate the open
ends of the chemical tubes with the tube stiffeners and place each one in the appropriate container.
A. Red Tubing = Detergent
B. Blue Tubing = Rinse Aid
C. White Tubing = Sanitizer.
PRIMING PERI-PUMPS
Peristaltic pumps need priming when the machine is first installed or if for some reason the chemical lines have been removed and air
is allowed to enter.
CAUTION: Water must be in the sump and wash tank prior to the dispensing of chemicals. Sanitizer in concentration is caustic and may cause damage without dilution.
1. Verify that the proper chemical tube stiffener inlet is in the proper container.
2. Use the toggle switches on the right side of control box to prime each pump. There are two (2) switches mounted by the peripumps. One will prime the sanitizer pump only, and the second will prime either the detergent or rinse aid pump, depending upon which
way it is depressed.
3. To prime the pumps, hold the switch in the momentary position until chemical can be observed entering the sump.
4. Detergent is dispensed as required during the wash cycle by the cam timer. The amount of detergent may need to be increased or
decreased depending on water quality and type of detergent. It is adjusted by changing Cam 7 on the cam timer. See the Conserver
24LTP cam timer operation instructions.
5. Rinse additive is dispensed as required into the final rinse. The amount of rinse aid may need to be adjusted depending on water
hardness and results. It can be changed by changing Cam 6 on the cam timer. See the Conserver 24LTP cam timer operation instructions.
6. Sanitizer (either chlorine or iodine) is dispensed into the final rinse. The amount of sanitizer may need to be adjusted depending on
the concentration and type of sanitizer used. It is adjusted by changing Cam 8 on the cam timer. See the Conserver 24LTP cam timer
operation instructions.
