BEFORE YOU BEGIN:
American Dish Service provides this information as a service to our customers. 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 must be performed by qualified personnel
who will ensure that the equipment is installed in accordance with all applicable Codes, Ordinances,
and Safety requirements. Failure to follow these requirements will void the war-
ranty. 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.
WARNING:
Always disconnect power to dishmachine and tag out
before servicing. Caution: Refer to chemical
suppliers MSDS sheets for proper handling and
chemical issues. Turn off machine at master switch
before opening for inspection.
IMPORTANT:
Dishmachines are 120 volt and require a 20 amp clean
circuit and suitable ground. It is recommended that new
equipment be installed with new circuit breakers.
NOTE TO INSTALLER:
DO NOT OPERATE MACHINE WITH SPRAY ARM INSTALLED
UNTIL MACHINE IS FLUSHED WITH WATER.
Fill machine with water and run though one cycle without spray
arm in place. This will flush installation debris from tank and
pump and prevent damage to spray arm bearing.
Water Heaters or boilers must provide the minimum temperature
required by the type of machine and a minimum recovery rate of
68 gallons per hour. The recommended temperature range for
optimal performance is 130-140 degrees F. Caution: Do not
exceed water tempertures above 150 degrees F.
FOR YOUR SAFETY
Read and observe all CAUTIONS and
WARNINGS shown throughout these
instructions. While performing
installations described in this booklet
APPROVED Personal Protective
Equipment, including SAFETY EYEWEAR must be worn.
IMPORTANT- Dishwasher MUST be installed to
allow for service of motor and rear plumbing. For the
pumped drain model, the water inlet line must be
flexible and long enough to remove the machine, as
well as the power line and drain hose. This is a code
requirement for cleaning and servicing undercounter
dishwashers.
Optional Accessories -
2 1/2 minute 8-cam timer for regular ET Series
(pre-wash, wash, rinse cycle)
2 minute timer
Sink drain adapter w/barb for pumped drain
Dishracks
Table Package: 48” table w/sink, pre-rinse,
wall shelf, scrap basket
Plumbing
Connect to Water Supply
Important: Always check for local plumbing codes before installing. Flush water lines before connecting
dishmachine.
Prior to plumbing the dishmacine, level machine by adjusting feet, at the bottom of each leg, up or down.
Water heaters or boilers must provide the minimum temperature required by the type of machine and a minimum recovery
rate of 68 gallons per hour. The recommended temperature range for optiomal performance is 130-140 degrees F.
Caution: Do not exceed water tempertures above 150 degrees F. Residential hot water heaters are not sufficient
for commercial application. Typical On-Demand or “Flash Heaters” do not have flow rates capable of supplying commercial dishwashers.
Connect 1/2” FPT water supply line to 1/2” FPT on the fresh water inlet manifold. Fresh water inlet manifold is on the
lower frame. Supply water must be 120 degress F. minimum (130-140 degress F. recommended) from primary heat
source. Building source water supply must be a minimum of 15 PSI flow during fill (water solenoid open).
Water Pressure Problems: Water pressure below 15 PSI flow will require additonal measures to resolve low presssure
issues. To resolve water pressure problem, increase pipe diameter to 3/4” coming directly from the hot water heater. If
problem persists, suggest installing pressure bladder tank at 5 gallon mimimum capacity. Another option, would be to
order the undercounter machine with a longer time cycle, allowing longer fill time.
Drain Requirements for Undercounter Dishmachines “ET Series”
Follow local codes
Gravity drain line is 1 1/2” pipe -WARNING: Never use anything smaller on a Gravity Drain.
Pumped drain is 3/4” hose, 6-feet long
Close petcock on wash pump before operating machine
Gravity Drain
Plumb undercounter dishmachine drain outlet (1 1/2” FPT) to waste drain pipe access. Dishmachine gravity drain is 8”
(on center) from the floor. If drain line has a long run increase pipe size to 2”.
Important: Drain access, including the trap, must be no higher than 7” from the floor.
Plumb drain line as straight as possible and verify that drains are free-running. Once plumbed run machine through a
complete cycle and check for leaks under the sump area. Inspect drain push rod for alignment and smooth up and down
movement.
To test for slow-running drains: Run machine through normal cycle, open door, and use manual drain switch to remove
water. Time the length it takes to completely empty the machine. If length of time is greater than ten (10) seconds,
sewer drain is clogged or restricted. Consult a plumber.
Pumped Drain
The 3/4” drain hose provided with the machine is 6-feet long and will transfer drain water frrom the machine to a wall drain.
Connect the hose to a 3/4” barb fitting and clamp the hose on the barb. The barb fitting is first screwed into a bushing
adapter that in turn screws into or onto the building’s drain pipe. This prevents the drain hose from coming out of the
drain and flooding the floor. The wall drain must have a trap prior to connection to the barb fitting. Do not install the hose
barb higher than 20” off the floor or the machine’s safety overflow protection will be defeated.
IMPORTANT: The pumped drain undercounter option is designed with a built-in overflow protection in the
event the water valve experiences a slow running leak. This overflow protection does not work if the drain
hose is run higher than 20” off the floor. Leaking that results from the tank overflow will be the responsibility
of the installer if the drain height exceeds 20” from the floor.
If the installer decides to run the drain line to an existing sink drain above the trap, ADS offers a barbed connection
adapter that will attach to a 1 1/2” tail piece and then connect to a 1 1/2” slip nut connection of the gas trap. The PVC
part must be cut to fit. The part number is #92-1088. Do not install on wall connections higher than 14”.
I MPORTANT FOR PUMP DRAIN MODELS: DO NOT PULL THE PUMP FILTER OUT FIRST.
First drain the machine with the drain switch, then remove the pump filter and empty the contents.
(Note: pulling the filter out first will cause drain pump clogging and service calls.)
