INSTRUCTIONS
INSTALLATION
Before installing the unit, check the packaging and machine for damage. If the packaging
is damaged, the machine might also be damaged. If there is damage to both packaging
and machine, do not throw away the packaging. The machine has been inspected and
packed at the factory and is expected to arrive to you in new, undamaged condition.
However, rough handling by carriers or others might result in damage to the unit while
in transit. If so, do not return the unit to the manufacturer. Instead, contact the carrier
and ask them to send a representative to the site to inspect the damage and complete
an inspection report. You must contact the carrier and the dealer that sold you the unit
within 48 hours of receiving the machine.
While unpacking the machine, ensure that there are no missing parts. If an item is
missing, contact the manufacturer immediately.
While unpacking an HH VER unit, note that the VER system is packaged separately.
Click here or on the instructions icon for a guide on mounting the VER system to the
machine.
The machine must be level in its operating location to prevent damage to the machine
during operation and to ensure the best results. The unit comes with four adjustable
bullet feet, which can be turned using a pair of channel locks (or by hand if the unit can
be raised safely). Ensure that the unit is level from side-to-side and front-to-back before
making any connections.
Plumbing connections must comply with all applicable local, state, and national
plumbing codes. The plumber is responsible for ensuring that the incoming water line
is thoroughly ushed before connecting it to any component of the machine. It is very
important to remove all foreign debris from the water line that might potentially get
trapped in the valves or cause an obstruction. Any valves that are fouled as a result of
foreign matter left in the water line—and any expenses resulting from this fouling—are
not the responsibility of the manufacturer.
A water hardness test must be performed to determine if a water treatment system
needs to be installed.
If water hardness tests at greater than 3 GPG, install the Scaltrol Water Treatment
system (see the Plumbing Options page) into the water line before the machine’s
incoming water connection point. A water shut-o󰀨 valve should be installed to allow
access for service.

CONNECTING THE
DRAIN LINE
If water hardness tests at less than 3 GPG, install the water supply line directly to
the machine’s incoming water connection point. A water shut-o󰀨 valve should be
installed to allow access for service.
The steam machines come with lines to connect the source steam. Connect all steam
lines to the machine as all applicable codes provide. See machine data plate for
information concerning steam ow pressure. Click here or on the instructions icon for
the Steam Booster manual.
The manufacturer recommends the installation of a water pressure regulator in the
incoming water line to ensure proper owrate at all times and o󰀨ers these devices as
options (see the Plumbing Options page). The PRV comes standard on the HH VER.
Do not confuse static pressure with ow pressure. Static pressure is the line pressure
in a “no ow” condition (all valves and services are closed). Flow pressure is the
pressure in the ll line when the ll valve is opened during the cycle.
The manufacturer also recommends the installation of a shock absorber in the
incoming water line and o󰀨ers these devices as options. This prevents line hammer/
hydraulic shock—induced by the solenoid valve as it operates—from causing damage
to the equipment (see the Plumbing Options page).
The machine's drain is a gravity-discharge drain. All piping from the 1 1/2” NPT
connection on the wash tank must be pitched (1/4” per foot) to the oor or sink drain.
All piping from the machine to the drain must be a minimum 1 1/2” NPT and must not
be reduced. There must also be an air-gap between the machine drain line and the
oor sink or drain. If a grease trap is required by code, it should have a ow capacity
of 5 GPM.
Determine which exhaust fan timer is on the machine (located in the control box)
and click the instructions icon beside that timer to access programming instructions.

CONNECTIONS
PLUMBING CHECK Slowly turn on the water supply to the machine after the incoming ll line and drain
line have been installed. Check for any leaks and repair as required. All leaks must be
repaired before operating the machine.
Detergent
Connect detergent by removing the bulkhead tting on the back of the machine and
replacing it with the appropriate dispensing equipment.
Chemical connections
should be made by the
chemical supplier.
Rinse-aid
Connect rinse-aid by removing one of the brass plugs at the base of the rinse injector
and replacing it with the appropriate dispensing equipment. See the "Plumbing - HH
VER" page for a depiction of the VER rinse injector.
Rinse-aid
Using deionized water or
other aggressive uids
will result in corrosion and
failure of components and
will void the warranty.
WARNING! Some of the
chemicals used in
dishwashing may cause
chemical burns if they
come in contact with skin.
Wear protective gear when
handling these chemicals.
If any skin comes in
contact with these
chemicals, immediately
follow the instructions
provided with the
chemicals for treatment.

Ensure that the power switch is in the "OFF" position and apply power to machine.
Check the incoming power at the terminal block and ensure it corresponds with the
voltage listed on the data plate. If not, contact a qualied service agency to examine
the problem. Do not run machine if voltage is too high or too low. Shut o󰀨 the service
breaker and advise all proper personnel of the location of the breaker and any prob-
lems. Replace the control box cover and tighten-down the screws.
This is a commercial machine and reaches temperatures that can exceed those
generated by a residential machine. Surrounding countertops, cabinets, ooring ma-
terial, and subooring material must be designed and/or selected with these higher
temperatures in mind.
Any damage to surrounding area caused by heat/moisture to materials that
are not recommended for higher temperatures will not be covered under
warranty or by the manufacturer.
The temperature setpoints on this unit have been set at the factory. They should
only be adjusted by an authorized service agent.
The manufacturer o󰀨ers an optional False Panel Kit for corner installations. See the
Kits page for kit part number. Click here for false panel/corner install instructions.
The manufacturer does NOT endorse "Tankless On-demand" water heaters
for use with their dishmachines. The manufacturer DOES endorse, and highly
recommends, the standard "Tank" style water heaters, sized to properly handle the
water heating requirements of the facility.

OPERATING INSTRUCTIONS
OPERATION
Before operating the unit, verify the following:
1. The tank is clean and free of debris.
2. The wash arms, rinse arms, sump strainer, and scrap screen are all installed
correctly.
3. The standpipe is installed.
To energize the unit, turn on the power at the service breaker. The voltage should
have been previously veried as being correct. If not, the voltage will have to be
veried.
Ensure that the mode switch is in the "AUTO" position, and place the power switch
into the "ON" position. The machine will ll automatically and shut-o󰀨 when the
appropriate level is reached (just below the scrap screen). The wash tub must be
completely lled before operating the wash pump to prevent damage to components.
Once the wash tub is lled, the unit is ready for operation.
Proper ware preparation will help ensure good results and fewer re-washes. If not
prepared properly, ware might not come out clean and the e󰀩ciency of the machine
will be reduced. Putting unscraped dishes into the machine a󰀨ects its performance,
so scraps should always be removed from ware before being loaded into a rack.
Pre-rinsing and pre-soaking are good ideas, especially for silverware and casserole
dishes.
Place cups and glasses upside-down in racks so they don't hold water during the
cycle. The machine sanitizes as well as cleans. To do this, ware must be properly
prepared before being placed in the machine.
Refer to the “Preparation” section and follow the instructions there. Afterward, ensure
that chemicals are supplied to the machine. If not, contact your chemical supplier.

For the rst operation of each day, it might be necessary to run the machine through
three cycles to ensure that all of the cold water is out of the system and to verify that
the unit is operating correctly. To cycle the machine, ensure that the power is on and
that the tub has lled to the correct level. Lift and close the door and the cycle light will
illuminate. The unit will start, run through the cycle, and shut-o󰀨 automatically. Repeat
this two more times. The unit should now be ready to wash a rack of ware.
To wash a rack, open the door completely (avoiding hot water that might drip from
the door) and slide the rack into the unit.
Close the door and the unit will start automatically. Once the cycle is complete, open
the door (again watching for the dripping hot water) and remove the rack of clean
ware. Replace with a rack of soiled ware and close the door. Repeat this process.
Based on use, the scrap screen might become clogged with soil and debris as the
workday progresses. Operators should regularly inspect the scrap screen to ensure
it has not become clogged. If clogged, it will reduce the washing capability of the
machine. Instruct operators to clean-out the scrap screen at regular intervals or as
required by workload. Do NOT beat strainers to remove debris.
1. Turn machine off by flipping the power switch to “OFF.”
2. Open the door and allow steam/heat to escape.
3. Remove the standpipe and allow the tub to drain.
WARNING! Wash tank water will be hot!
