Keep all instructions for future reference. ADS reserves the right to alter or update this information at any

time. Should you desire to make sure that you have the most up-to-date information, we would direct you

to the appropriate document on our web site: www.americandish.com. Set out below are the specifications

and requirements that you must use and follow to properly install the type or types of equipment listed

above. It is your obligation as the customer to ensure that the machine is installed safely and properly, and

when completed, the machine is left in proper and safe working order. Electrical, Plumbing, and Chemical

hookup should be performed by a qualified professional who will ensure that the equipment is installed in

accordance with all applicable Codes, Ordinances, and Safety requirements. Failure to follow the

installation instructions could void the warranty. ADS assumes no liability or control over the installation of

the equipment. Product failure due to improper installation is not covered under the ADS Warranty.

#2 HEAVY USE ITEM— A conveyor dishmachine is often run at full capacity. The machine is not rated for

outdoor use.

#3 FLUSH OUT INITIAL FILL WATER— Do not install spray arms until machine is flushed with water. When this

machine is connected to power, it will normally fill with water . Do this without installing the spray arms.

Place a rack inside the machine so all the pumps will run. Afterward, drain all the water from the tanks,

install all spray arms, and refill the machine. To drain, pull the pump filter out of the sump and the stand

tube from the rinse tank (for the 66, also pull the large scrap basket from the power scrapper tank).

#4 CLEARANCES—Dishmachines must be installed to allow for servicing of motors and conveyor systems.

Do not install chemical dispensers on the top of the control box, machine, or booster.

#5 WATER HEATERS—or boilers must provide the minimum temperature of 120F degrees required by the

machines listed above, which have a minimum hourly demand of 120 gallons per hour. For HOT WATER

SANITIZING, a booster heater must be installed to achieve the 180F minimum for the final rinse. This

booster will require a rise of 70-degrees. These specifications are for the dishmachine only, which typically

accounts for 70% of a restaurant’s hot water demand.

#6 INSPECT FOR DAMAGE—If you receive a damaged dishmachine, do not sign “Clear” but write

“Damaged” on the documents.

#7 TABLES— are critical to proper dishmachine operation. No table drains (quick drains) or sinks within 20”

of the dishmachine on soil table. No sinks or drains on clean tables. Slant tables toward the machine and

anchor to the machine lip with the four ¼” bolts supplied. Table lip must not rub on the conveyor bar. If

needed, cut out a half-round in the table lip for clearance of the conveyor bar. Tray tracks are not adjustable

up or down because of the switch activators. Fasten tables to the machine so they are level with the tray

track. Curves or “bands” on clean table seldom work correctly, we recommend using ADS table limit switch

(kit 288-1044) for short exit tables.

#8 REQUIRED by NSF — This machine must be operated with an automatic detergent feeder and, if

applicable, an automatic chemical sanitizer feeder, including a visual means to verify that detergents and

sanitizers are delivered or a visual or audible alarm to signal if detergents and sanitizers are not available for

delivery to the respective washing and sanitizing systems. Please see instruction for electrical and plumbing

connections located in this manual and in the feeder equipment manual.

ELECTRICAL SECTION

The electrical power supplied to this machine is an imminent hazard that could result in severe bodily

injury or death if not properly installed or hooked up correctly

#1 Before powering up the machine, CHECK ALL ELECTRICAL SCREW TERMINALS in the control box on top of

the machine, power box, and both heater boxes located under the tanks. Screws can loosen in transit.

Loose connections on high amp load terminals will cause wire burning and component damage during

operation and will not be covered under ADS warranty. The term “Clean Circuit” means the electrical circuit

breaker supplies no other devices, motors, machines, or lights.

#2 ADS Conveyor models DO NOT INCLUDE an internal booster heater. Boosters must be installed

separately, ADS recommends a 27 kW for 155 GPH at a 70-degree rise.

3-Phase MOTOR ROTATION—Remove front panels and check rotation of motors. A rotational arrow is placed

on the wash pump motor. If this motor is running in reverse of the arrow, turn off main power and switch the

incoming power wires on L1 & L2. This step will correct the rotation of the other motors at the same time.

Verify proper rotation and tighten all wires.

IT IS RECOMMENDED THAT THIS EQUIPMENT BE INSTALLED USING A NEW CIRCUIT BREAKER.

PLUMBING SECTION

#1 TANKLESS WATER HEATERS can be problematic for commercial dishmachines. The ADS models ADC-44/66

dishmachines require heated water 120 gallons per hour at 20 psi as measured at the final rinse manifold,

with a minimum temperature of 120F. It has been the experience of ADS that tankless supply systems

require multiple units plumbed in sequence with a recirculation loop to achieve proper pressure and

temperature.

Check with the tankless water heater manufacturer, they may recommend a storage tank to guarantee

proper flow and line pressure to the machine. Failure to provide adequate water quantity, pressure and

temperature to the machine will cause the machine to function improperly and is not the responsibility of

ADS. Improperly installing ADS equipment in this manner could void the warranty. All costs associated with

providing an adequate water supply to the machine is the sole responsibility of the user.

#2 DRAIN SIZE—Gravity drain lines are 2” pipe size. Do not use reducing adapters for drain lines, always use

same diameter pipe or larger. Close pump petcocks if equipped.

#3 A PRESSURE REDUCING valve with by-pass should be installed before the booster heater if the line

pressure is 50 psi or above. This is according to booster manufacturer’s instructions.

#4 BURN HAZARD from hot water from pump sprays or plumbing leaks.

#5 ELECTRICAL SHOCK HAZARD on bare electrical terminals in the thermostat boxes, power box, float

switch boxes, and control box.

#6 HOODS—Follow all local plumbing and mechanical codes. IMC 2012, section 507.2.2 requires Type II hoods for all

commercial dishwashers except where the heat and moisture loads are incorporated into the building’s HVAC systems or

dishwashing equipment designed with separate heat and moisture removal systems. A conveyor-type, hot-water sanitizing

dishwasher is rated at 21,720 Btu/h by table 5E, ASHRAE Research Project #1362, 8/5/2008.

ADS DOES NOT SPECIFY BUILDING HVAC VALUES

Hot water inlet manifold, single point ¾” pipe, PR valve Final rinse manifold with pressure gauge, 20 psi flow req.

Flush building’s water lines before connecting to dishmachine.

DUAL SANITIZING MODE

Hot Water Sanitizer Connection

For high temp sanitizing this line will come from a stand-alone booster heater. Connect ¾” MPT water supply

line to the 90-degree elbow of the dishmachine’s inlet manifold. The requirement at the dishmachine is 180 F

minimum at 20 PSI during final rinse flow, 120 GPH. This is measured at the pressure gauge mounted next to

the pressure reducing valve in the inlet plumbing on top of the machine’s hood. To adjust pressure, turn

adjustment screw atop the valve counter-clockwise to decrease pressure.

Chemical Sanitizer Connection

For chemical sanitizing this line will come directly from the building’s water heater. Connect ¾” MPT water

supply line to the 90-degree elbow of the dishmachine’s inlet manifold. The requirement at the dishmachine is

120 F minimum at 20 PSI during final rinse flow, 120 GPH. This is measured at the pressure gauge mounted

next to the pressure reducing valve in the inlet plumbing on top of the machine’s hood. To adjust pressure,

turn adjustment screw atop the valve counter-clockwise to decrease pressure. A dispenser with three product

pumps is required for chemical sanitizing (chlorine pump)

Drain Requirements

Showing 2” drain manifold exiting sump & scrap box Scrap box and tray

ADS provides a 2” copper common drain that exits on the soil side of the dishmachine under the scrap box

(ADC-66 drain exits both sides). To prevent clogging, run drain lines as straight as possible. Do not plumb with

tight radius elbows or 180-degree bends. Use of floor sinks for drains can cause flooding. Do not use reducing

adapters for drain lines, always use 2” diameter pipe or larger. Always run gravity drain lines downhill.

DISPENSER HOOK-UP SECTION

You must wear approved safety eye-wear before connecting chemical equipment. Commercial cleaning

chemicals are harmful and can cause damage to the plumbing and stainless steel of the dishmachine. Do

not mount dispensers on the control box or run chemical lines over controls or plumbing. Always secure

chemical lines and check regularly for leaks. If not properly handled, chemicals can cause serious bodily

injury. In the event of chemical contact to skin or eyes; wash immediately with fresh water and seek

medical attention.

There is NO CHEMICAL DISPENSER included with this model. Chemical dispensers must be provided and

installed prior to operation. The installation of the dispenser is typically provided by the chemical supplier.

CONTAINERS: When a chemical delivery system is connected to the ADS conveyor dishmachine using 5-gallon

pails for industrial ware-washing chemical products these must be equipped with Closed Loop containers.

Always use chemical resistant safety gloves and safety goggles (indirect- vented or non-vented) when changing

chemical buckets. Immediately report spills and refer to your chemical suppliers SDS safety data sheet or

MSDS material safety data sheet for information if chemical come in contact with skin or eyes.

Any modifications to the chemical delivery system for smaller containers must include Closed Loop Chemical

Containers (spill proof bottles) in a secured racking system. It is the responsibility of the user of the machine

to purchase chemicals in spill proof containers. FAILURE CAN RESULT IN SERIOUS INJURY. Never place

chemicals in open containers or containers that can be easily tipped over when moving or changing product.

Failure to do so is a safety hazard and will also void the ADS warranty.

Mixing chamber with two 1/8” pipe threaded ports Showing 7/8” detergent probe hole behind pump motor

Hi-temp mixing chamber is SS, Chemical is a polymer

ADS provides two (2) ports, 1/8” IPS female threads in the final rinse mixing chamber for dispenser check

valves. Probe hole (7/8”) is provided in the wash tank for probe installations (install probe before operating

the machine). Detergent hole (7/8”) is provided for bulk-head fitting (install fitting before operating machine).

Showing hole at the side of tank, 7/8” detergent fitting Dispenser signal connection terminals in control box

NOTE: Before turning on the water, if the chemical dispenser has not been installed, plug the probe and

chemical delivery holes in the wash tank and plug the mixing chamber injection ports.

ADC-44, 3-phase provides 240v dispenser signals (transformer control voltage).

ADC-66, 3-phase provides 120v dispenser signals.

Connect to chemical dispenser terminal blocks located on the left-hand side of the control box, look for yellow

decal labeled detergent and rinse

TESTING FOR TEMPERATURE—For high temp sanitizing, the measurement is taken at the manifold for a

minimum of 180F, NOT in or at the sprays. If color changing tapes are used to verify temperature, then only

160-165F labels should be used, this is the highest temperature required on the surface of the plates--NOT

180F. This is according to the NSF/ANSI Standard 3 test protocol.

TYPE OF CHEMICALS—Use only commercial grade low-energy or high temp chemicals. For proper operation,

use non-foaming detergents and buffered sanitizer. Do not wash gold, pewter, silver, or silver-plate with

chlorine based sanitizers. High concentrations of chlorine sanitizers and caustic detergents will cause damage

to metals and welds. Do not exceed 50 parts-per-million (PPM) “free” or available chlorine, using higher than

50 ppm will be dependent on local health requirements, however, the increased chlorine will result in higher

corrosion of metal parts. Purpose-built ware-washing dispensers are needed to properly meter chemicals for

wash and rinse. These dispensers are not included with this model but must be installed by the company that

provides the ware-washing chemicals. Manually adding industrial chemicals to the dishmachine is unsafe and

not approved.

HARD WATER—Water softeners should be used to correct hard water conditions. Treating hard water

conditions with highly acidic solutions in the machine is discouraged. Hard water conditions are often treated

with more expensive dishmachine chemicals, but it is more effective and less destructive to the metal when

the water is softened before it is used by the dishmachine.

CHECK LIST PRIOR TO INITIAL START UP

Open doors and remove all packaging, including cardboard supports under the wash tank heater. Do not

dispose of packing material until you remove spray arms and curtains. Packing materials contain the conveyor

installation manual, QC check sheets, curtains; upper and lower wash arms, pumped rinse arms, and power

scrapper arms for the ADC-66.

Showing wash arm T index for lower arm Arm resting in “T” index with latch down

Showing pumped rinse manifold locking tab Rinse arm index notch, latch will drop as arm is pushed in

Install wash and pumped rinse spray arms. Lower wash arm has eight spray tubes and upper wash arm has

four. Install each by inserting indexed “T” end into bracket at front of tank, and then push the arm back until

the round socket is fully inserted on the wash manifold near the back wall. Position the “T” bracket latch to

secure wash arms in place by pulling down. Install power scrapper arms (ADC-66 only) and pumped rinse

spray arms. Each arm has a locking tab. Lower arm locking tabs are located on the same side as the spray jets.

Upper arm locking tabs are opposite the spray jets side. Insert the tab into the index slot of each manifold

socket until socket catch locks in place. Note: make sure that spray jets on the bottom arms spray up, and top

arms spray down.

ADC-66 power scrapper, overflow to scrap box 66 power scrapper motor, 1.5 HP, 208v, single-phase

Inspect all dish racks for broken ladders. Dispose of any broken dish racks.

IMPORTANT TABLE INSTRUCTIONS— Allow for one rack (20”) length as a minimum distance

between the edge of the pre-rinse sink and the entrance of the machine on the soil dish table. Failure to do

this will result in excessive chemical consumption and low machine temperatures. Do not use tables with

quick drains or scrap troughs. Observe that the dish table lip does not rub on the conveyor bar; if the lip is

longer than ¾” a notch will have to be made for clearance. Make certain that both dish tables slant into the

machine so water will return to the tanks. To avoid service calls and motor damage, bolt clean and soil tables

level to the machine’s tank lip and seal. New drill bits and ¼-20” bolts are included with each machine.

TABLE LIMIT SWITCH—Check clean dish table, if it holds less than four (4) dish racks, install an ADS table limit

switch (#288-1044). The switch holder attaches to the back side of the table end. The bumper bar will extend through

the table and pin to the rocker plate. When racks strike the bar, the switch will break the power connection in the

machine’s door cut-off switch, which stops all motors.

ADS table limit, and table bumper bar (#288-1044)

Tighten all wire connections looking for those that loosened during shipping or moving. Turn on the water

supply. Check and correct any leaks throughout the machine. Verify incoming water temperatures and final

rinse pressure (20 psi during spraying). Remove any of the white protective film from stainless surfaces such as

doors or panels.

DISHMACHINE OPERATIONAL TESTS

BURN HAZARD FROM HOT WATER. Do not open doors while machine

is in cycle. Doing so could result in serious bodily injury from spraying hot water and chemicals.

To operate, turn on the breaker for main power and turn the dishmachine master switch to the “ON” position.

Showing “float” switch that controls fill water & heater Diverter plate separates fill stream for wash and rinse tank

FILLING THE MACHINE— When the machine is first turned on, water will automatically fill to an initial working

level. During operation the water level will normally increase with each rack until water begins to exit the

overflow into the scrap box. Open the access door and verify that the filling water is adjusted so the wash tank

fills first and rinse tank fills last. For the ADC-66 the wash tank must overflow to fill the power scrapper tank.

The last tank to fill should be the pumped rinse tank. If the fill sequence does not follow this order, adjust the

diverter plate inside the hood, it is located upward near the water inlet (see photo above). Slotted holes allow

the diverter plate to move side to side adjusting the flow to the rinse tank. The water stream going into the

pumped rinse tank should be about the diameter of a pencil. It is normal for the machine to add more water

when the pump turns on if the level has not yet reached the overflow.

Rinse tank float, pump filter, pumped rinse manifold Wash tank float and tank overflow

“FLOAT” AND SWITCH—the float will not actually float. It is heavier than water but it weighs less in water than

in air. This difference allows the return spring in the float switch to push out against the lever, which raises the

float in the water. In air the float’s weight will overcome the switch’s spring tension and drop down. The float

switch (#291-3014) is specifically made with this spring tension so the water control system will operate

correctly. Do not replace with a timer switch even though they look similar.

Travel through conveyor tray rails, center pull bar w/dogs Damaged and broken rack that will jam or skip conveyor

TEST DISH RACK CONVEYOR MOVEMENT by placing a rack into the soil side opening until it catches on a

conveyor dog. The rack should enter and exit smoothly without jamming. The dishmachine tray track will not

adjust up or down, it is fixed. Tables must sit on the tank lip. Verify that tables are bolted to the machine, and

once bolted, sealed with silicone caulking at all four corners and under the lip. Check that all varieties and

brands of dishrack can fit between the dishmachine’s tray track rails without binding. If binding occurs, adjust

the REAR tray track at all (3) anchor points until the rack binding is eliminated. You must adjust evenly at all

three points to maintain proper alignment. Never adjust the front tray track, they contain switching

alignments.

Conveyor cam blocks A & B Rocker arm slip clutch spring, hook to bar weldment

Cam bearing screws into cam block B Rocker arm attached to conveyor bar, drip chute

Keep away from conveyor rocker arm movement to avoid severe bodily injury from pinch or crush danger

THE FRONT TRAY TRACK has sequence bars that turn on the pumps at each station of the dishmachine’s

operation. There is a sequence bar for the power scrapper (on the ADC-66 only), wash, and final rinse

sections. To confirm proper operation, push a dishrack into the soil side opening and see that it is conveyed

through each section without binding or stoppages.

POWER SCRAPPER (ADC-66 only) – Run one dishrack through the machine. Following initial fill, if there is an

air lock in the scrapper pump, this is normal. The pump will equalize after being operated once. The power

scrapper pump motor is the standard ADS single-phase 1.5HP motor wired for 208v instead of 115v. Make

certain replacement motors are first wired for high voltage (see diagram on motor).

WASH SECTION – Verify that the wash sequence bar starts the wash pump when the dishrack contacts the bar,

and the pump stops when the dishrack moves out of that section of the dishmachine.

FINAL RINSE SECTION – The last sequence bar will control the final rinse and pumped rinse. The pumped rinse,

which is called the water curtain, should begin when a dishrack contacts the bar. This is a low pressure spray

and the lower spray should only rise 4-6” from the arm. After a six second delay, the final rinse will begin to

spray. All functions should stop when the dishrack exits the machine unless there is another rack still inside.

Sequence reed switch for wash tank Wash tank sequence bar, pendulum with magnet

SEQUENCE BAR MAGNETS— The magnets located on the pendulum sequence bars inside the tank activate the

reed switches, which are manufactured in the normally closed position (always on). The reed switch is

mounted to the outside of the tank and turns off when a magnet comes within ½” of the switch. To test, hold

a strong hand-held magnet next to the reed switch. If the magnet turns off the reed switch but the sequence

bar magnet does not, adjust the sequence bar magnet for that section. The sequence bar magnet should be

within a 1/8” of the bottom of the tank when it is at rest (hanging down at the 6:00 position).

TANK TEMPERATURE—The wash and pumped rinse tank temperatures are maintained by sustainer heaters.

Record tank temperatures during the initial tests. There are three (3) gauges mounted under the control box.

Gauges are marked Wash/Rinse/Final Rinse. Wash tank temperature should be 140F-degrees for chemical

sanitizing and 150F-degrees for hot water sanitizing in multi-tank conveyors. The pumped rinse tank

temperature should be 120F-degrees for chemical and 160F-degrees for hot water sanitizing. If tank

temperatures are low, increase by adjusting the heater thermostats located behind the front panels.

Wash tank thermostat, rotate center rod Left to increase T-stat signal goes to term #6 on heater relay under contactor

THERMOSTATS—There are two thermostats, one for each tank. Increase temp by turning center rod of the

thermostat counter clock-wise or turn to the left. Adjust thermostats in small increments (1/4 turn). Heaters

are switched off when water levels are low and the fill has been activated. Final rinse temperatures are 120F

for chemical sanitizers, and 180F for hot water sanitizing. To increase the final rinse temperatures turn up the

thermostat on the booster heater or water heater respectively. Do not set a booster heater above 195F.

INSTALL CURTAINS— There are two short and two long curtains. Longer curtains are mounted at each end of

the dishmachine. Curtains are there to keep heat in the water.

Vent attachments to end shield, 4” x 16” opening 200 to 400 CFM draw per side

VENTING—If exhaust vents (pant-leg vents) are attached to the dishmachine, do not exceed 400 CFM per

individual pant leg. ADS does not specify building HVAC values and only offers this limit as a point of reference.
