Unpacking
WARNING:
Care should be taken when lifting the machine to prevent damage.
1. Immediately after unpacking your machine, inspect for any shipping damage. If damage is
found, save the packing material and contact the carrier immediately.
2. Remove the dishwasher from the skid. Adjust the feet if required, then move the machine to
its permanent location.
3. Level the machine (if required) by placing a level on the top of the machine and adjusting
the feet. Level the machine front-to-back and side-to-side.
CAUTION:
After locating your machine, the installation must meet local health codes. An example may
be to seal your machine to the floor using a good grade of silicone sealant.
Electrical Connections
WARNING:
Electrical and grounding connections must comply with the National Electrical Code
and/or Local Electrical Codes.
WARNING:
When working on the dishwasher, disconnect the electric service and tag it to indicate work
is being done on that circuit.
1. The electrician should compare the electrical specifications on the machine electrical rating
label (located on the lower left front panel) to the electrical power supply before connecting
the machine to the incoming service at a fused disconnect switch.
NOTE:
The 208-240V/60Hz/1PH electrical supply service for this machine must be a
3-wire plus ground service.
2. On the 208V-240V models, a terminal block is provided on the left front side of the
machine (located behind the front panel) for electrical service connections. A fused
disconnect switch or circuit breaker (supplied by user) is required to protect each power
supply circuit.
3. On 115V models, your machine is already equipped with a 4-foot power cord and plug
suitable for 115V-15A service.

Plumbing Connections
CAUTION:
Plumbing connections must comply with local sanitary and plumbing codes.
Water Connections
1. Connect the hot water supply (60°C/ 140°F Min) to the 1/2" I.D. fill hose provided. The fill
solenoid valve is equipped with a flow control that will accept water pressures from 172
kPa/25 psi to 665 kPa/95 psi.
2. Install a manual shut-off valve with 3/4" garden hose connection in the water supply line
close to the machine to accommodate installation and servicing the machine. The shut-off
valve should be the same size or larger than the supply line.
3. The fill solenoid valve is equipped with a built-in strainer to protect from particles in the
water supply.
Drain Connections
1. All Models are supplied with a flexible 5/8" I.D. drain hose, which must be connected to a
1-1/2" drain using a wye (Y) fitting close to the machine.

chemical dispensing pump(s). The cams control the length of time that the pumps operate.
A qualified person may adjust the cam settings if necessary. Refer to the timer chart
diagram(s) at the end of the manual for timer cam locations. Factory time settings are only
approximate. Have your chemical supplier check the concentration and make the necessary
adjustments.

MAINTENANCE
MAINTENANCE
The efficiency and life of your machine is increased by regularly scheduled preventive
maintenance. A well maintained machine gives better results and service. An investment of a few
minutes of daily maintenance will be worthwhile.
The best maintenance you can provide is to keep your machine clean. Components that are not
regularly cleaned and flushed will clog and become inoperative.
Intervals shown in the following schedules represent an average length of time between necessary
maintenance. Maintenance intervals should be shortened whenever your machine is faced with
abnormal working conditions, hard water, or multiple shift operations.
Cleaning Schedule
• Daily-Every 8 Hours
1. Depress the ON/FILL/OFF/DRAIN switch to OFF/DRAIN position and close and
latch the door to drain the tank.
2. Open the door and remove the upper and lower spray arms by unscrewing the knurled
fastener.
3. Remove the scrap screen carefully to keep soil or waste particles from falling into the
sump. Remove any material caught in pump intake.
4. Clean inside the tank with clean water. Backflush the scrap screen until it is clean. Do
not strike the screen against solid objects.
5. Clean the wash arms to remove any debris from spray openings. Do not strike the
spray arms against solid objects.
6. Reinstall the scrap screen and spray arms.
7. Leave the door open overnight to allow drying.
8. Report any unusual conditions to your supervisor.
• Meal Periods
1. Clean the scrap screen after every meal period and more frequently during heavy
usage. Do not allow the scrap screen to become clogged with soil or waste particles.
Page 17
11
MAINTENANCE
Maintenance Schedule
• As Required
1. Check the temperature gauge reading to make sure that it is accurate.
2. Check the chemical supplies and refill as necessary.
• Weekly
1. Inspect all water lines for leaks and tighten them at joints if required.
2. Clean all detergent residue from the exterior of the machine.
3. Check the drain for leaks.
4. Remove and closely inspect the spray arms for blockage.
5. Check for damage to the scrap screen. Ineffective screening can cause wash system
failures, or poor washing results.
6. Clean the detergent, sanitizer, and rinse aid supply tubes. Complete the following
procedure:
a. Remove the detergent, sanitizer, and rinse aid pick-up tube(s) from the
container(s). Place the tube(s) into a container of hot water.
b. Ensure ON/FILL/OFF/DRAIN switch is in the ON position depress and hold
the DET prime switch (located on the front panel) until clear water enters the
tank through the fill air gap (located on the right side of the tank).
c. Your machine is equipped with a sanitizer and/or rinse aid pump, follow the
same procedure by pressing the SANITIZER and/or the RINSE AID prime
switch until clear water enters the tank through the fill air gap.
d. When completed, remove the pickup tubes from the hot water and reinsert them
into the correct chemical containers. Repeat the priming procedures to ensure
that chemicals have filled the tubes for the next operating period.
e. Run a complete cycle to flush chemicals from the tank.
Page 18

MAINTENANCE
Deliming
Your dishwasher should be delimed regularly. The frequency will depend on the mineral content
of your water.
Inspect your machine interior for lime deposits. If deliming is required, a deliming agent should
be used for best results.
DANGER:
Deliming solution or other acids must not come in contact with household bleach (sodium
hypochlorite) or any chemicals containing chlorine, iodine, bromine, or fluorine. Mixing
will cause hazardous gases to form. Skin contact with deliming solutions can cause severe
irritation and possible chemical burns. Consult your chemical supplier for specific safety
precautions.
If you have the chemical sanitizing model (401-LT PLUS), carefully follow the following
procedure before deliming:
1. Remove the sanitizer tube from the container. Place the tube into a container of hot water.
2. Depress and hold the SANITIZER prime switch (located on the front panel) until all
sanitizer has been purged from the hoses.
3. Close the door and depress the door latch. Complete two operating cycles to purge the
machine of all sanitizer.
Deliming Procedure
Complete the following procedure to delime your machine:
1. Add the delime chemical to wash the tank (per chemical supplier specifications).
2. Close and latch the door.
3. The dishwasher will complete a regular cycle.
4. Check the deliming results and repeat if necessary per the chemical supplier’s
specifications.
5. Operate the dishwasher for at least four complete cycles to purge the machine of any
deliming chemicals.
6. Drain the dishwasher. Deliming is complete.
