INSPECTION
Do not throw away
packaging if damage is
evident!
UNPACKING
PLUMBING
The plumber must ush
the incoming water line!
Before installing the machine, check packaging and machine for damage. Damaged
packaging might be an indication of damage to the machine. If there is any type of
damage to both packaging and unit, do not throw away the packaging. The machine
has been inspected at the factory before shipping and is expected to arrive in new,
undamaged condition. However, rough handling by carriers or others might result in
damage to the machine while in transit. If this occurs, do not return the machine to
the manufacturer. Instead, contact the carrier and ask them to send a representative
to the site to inspect the damage and request that an inspection report be completed.
Contact the carrier within 48 hours of receiving the machine as well as the dealer that
sold you the machine.
The machine should be unpacked and removed from the pallet before installing. Open
the front door and remove all materials from inside. Once unpacked, verify there are no
missing parts. If a part is missing, contact the manufacturer immediately.
All plumbing connections must be made to adhere to local, state, territorial, and
national codes. The installing plumber is responsible for ensuring the incoming
water lines are ushed of debris before connecting to the machine. Note that chips
and materials from cutting processes can become lodged in the solenoid valves
and prevent them from opening or closing. Any valves that are found to be fouled
or defective because of foreign matter left in the water line, and any subsequent
damage, are not the responsibility of the manufacturer.
WATER SUPPLY
CONNECTIONS:
WATER HARDNESS
HIGHER THAN 3 GPG
A water hardness test
must be performed.
See the HT-E Dimensions or HT-E-SEER Dimensions page (depending on your
model) and reference item "B" for water inlet connection location.
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.
A water hardness test must be performed. There is a hardness test kit on the warning
tag attached to the incoming plumbing connection on the back of the machine. If
water hardness is higher than 3 GPG and a water softener is not being used, install
an SPS (see Plumbing Options page) into the water line between the facility water line
and the machine water line (installed at the factory). Observe proper inlet/outlet water
directions. A water shut-o valve should be installed before installing the SPS to allow
access for service. The water supply must be capable of a minimum of 10 PSI “ow”
pressure at the recommended temperature indicated on the data plate.

Take care not to confuse

SHOCK ABSORBER
If water hardness tests at 3 GPG or lower, connect the machine water line (installed
at the factory) to the facility water line. A water shut-o valve should be installed in
the water line between the facility supply and the machine to allow access for service.
The water supply line must be capable of a minimum of 10 PSI “ow” pressure at the
recommended temperature indicated on the data plate.
The manufacturer recommends the installation of a pressure regulating valve (PRV)
in the incoming water line to ensure proper owrate at all times and oers them as
an option (see the Plumbing Options page). The PRV comes standard on the HT-ESEER. 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 on the
incoming water line and oers them as an option (see the Plumbing Options page). A
shock absober comes standard on the HT-E-SEER. This prevents water hammer or
hydraulic shock—induced by the solenoid valve as it operates—from causing damage
to the equipment.
CONNECTING THE
DRAIN LINE
The machine has a pumped (pressure) drain capable of pumping waste water to
a height of 24” above the oor to the kitchen’s drain system. Each dishmachine is
supplied with a drain hose. When installed, it will extend from the rear side of the
machine. There must be an air-gap between the machine drain line and the oor sink
or drain at least 1.5 times larger than the drain hose. If a grease trap is required by
code, it should have a ow capacity of 12 GPM.
Air-gap
≤24”

PLUMBING CHECK
07610-004-43-79-L
After installing the incoming ll line and drain line, turn on the water supply to the
machine. Check for any leaks and repair as required. All leaks must be repaired
before operating the machine.

PREPARATION
WASHING A RACK
OF WARE
Proper ware preparation helps ensure good results and fewer re-washes. If not done
properly, ware might not come out clean and the eciency of the dishmachine will
be reduced. 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.
1. Follow the Filling the Wash Tub section, ensuring temperature is at least 155 °F

DETERGENT CONTROL
DETERGENT
CONTROL
Detergent usage and water hardness are two factors that greatly contribute to the
machine's operating eciency. Using the proper amount of detergent can become a
source of substantial savings. A qualied water-treatment specialist can determine
what is needed for maximum eciency from the detergent.
• Hard water greatly aects the performance of the machine, causing the amount
of detergent required for washing to increase. If the machine is installed in an
area with hard water, the manufacturer recommends the installation of water
treatment equipment.
• Deposited solids from hard water can cause spotting that will not be removed
with a drying agent. Treated water will reduce this occurence.
• Treated water might not be suitable for use in other areas of operation and it
might be necessary to install a water treatment system for the water going to the
machine only. Discuss this option with a qualied water treatment specialist.
• Properly train operators on how much detergent is to be used per cycle. Meet
with a water treatment specialist and chemical supplier to discuss a complete
training program for operators.
• Water temperature is an important factor in ensuring the machine functions
properly, and the machine's data plate details what the minimum temperatures
i
must be for the incoming water supply, the wash tank, and the rinse tank. If
minimum requirements are not met, it's possible that dishes will not be clean or
sanitized.
• Instruct operators to observe the required temperatures and to report when they
fall below the minimum allowed. A loss of temperature can indicate a larger
problem.
