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 speciﬁ cations 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 qualiﬁ ed 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 ﬂ ushed with water. When this machine is connected to power, it will normally ﬁ ll 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 reﬁ ll the machine. To drain, pull the pump ﬁ lter 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 120°F 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 180°F minimum for the ﬁ nal rinse. This booster will require a rise of 70°. These speciﬁ cations 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 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.

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°rise.

Electrical ADC-44, 208v/240v, 3-ph, 60a

ORDERING INSTRUCTIONS—Machines with heaters are voltage speciﬁ c, order according to actual voltage at the installation (see kW chart in appendix)

The power supply of 208 volts, 60 amps must consist of three 6-gauge wires and a suitable ground. The 60 amp breaker or fuses must be on a clean circuit to the machine. ADS has provided a conduit hole (1 3/8”actual size) for 1” conduit for the electrical service into the back of the control box. Attach the 6-gauge wires to the main distribution block in the control box to terminals marked L1, L2, & L3. Attach a building ground wire to the main distribution block marked GND and tighten all wires.

FOR 240 VOLT OR DELTA SYSTEMS—attach the high leg (200 volt line) to L3. Attach your 120 volt lines to L1 and L2. If power is 240v, see kW rating chart at the back of the manual for correct heater sizing and available ADS heater elements.

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.

note Neutral

Electrical ADC-66, 208v/240v, 3-ph, 90a, w/10-gauge neutral

ORDERING INSTRUCTIONS—Machines with heaters are voltage speciﬁ c, order according to actual voltage at the installation (see kW chart in appendix)

The power supply (208 volt, 90 amps) must consist of three 3-gauge wires, a 10-gauge neutral, and a suitable ground. The 90 amp breaker or fuses must be on a clean circuit to the machine. ADS has provided a conduit hole (1 3/4”actual size) for 1 1/4” conduit for electrical service in the back of the control box. Attach the 3-gauge wires to the main distribution block in the control box, to terminals marked L1, L2, & L3. Attach 10-gauge neutral and ground wire to their proper locations on the main distribution block and tighten all wires.

FOR 240 VOLT OR DELTA SYSTEMS— attach the high leg (200 volt line) to L3. Attach your 120 volt lines to L1 and L2. If power is 240v, see kW rating chart at the back of the manual for correct heater sizing and available ADS heater elements.

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 ﬁ nal rinse manifold, with a minimum temperature of 120°F. 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 ﬂ ow 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.

BURN HAZARD from hot water from pump sprays or plumbing leaks. ELECTRICAL SHOCK HAZARD on bare electrical terminals in the thermostat boxes,

power box, ﬂ oat 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

Flush building’s water lines before connecting to dishmachine.

Final rinse manifold with pressure gauge, 20 psi ﬂ ow req.

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° elbow of the dishmachine’s inlet manifold. The requirement at the dishmachine is 180° F minimum at 20 PSI during ﬁ nal rinse ﬂ ow, 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° elbow of the dishmachine’s inlet manifold. The requirement at the dishmachine is 120° F minimum at 20 PSI during ﬁ nal rinse ﬂ ow, 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

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° bends. Use of ﬂ oor sinks for drains can cause ﬂ ooding. Do not use reducing adapters for drain lines, always use 2” diameter pipe or larger. Always run gravity drain lines downhill.

Scrap box and tray

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.
