Before installing 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 machine, 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 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 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 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.
A water hardness test must be performed. If water hardness is higher than 3 GPG,
install a water softener or install the optional Scale Prevention System (SPS). See the
next section and the Plumbing Options page for more information on the SPS.
If water hardness is higher than 3 GPG and a water softener is not being used, install
the SPS into the water line between the facility water line and machine water line.
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 the minimum “ow” pressure at the recommended temperature indicated
on the data plate.

CONNECTING THE
DRAIN LINE
If water hardness tests at 3 GPG or lower, connect the machine water line (installed
at the factory, 3/4" Male GHT connected to a true 1/2” ID line) 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 the minimum “ow” pressure at the recommended temperature indicated on the
data plate.
The manufacturer has an optional Pressure Regulating Valve (PRV) to accommodate
areas where water pressure uctuates or is higher than the recommended pressure.
Take care not to confuse static pressure with ow pressure. Static pressure is line
pressure in a “no ow” condition (all valves and services are closed). Flow pressure is
the pressure in the ll line when the valve is open during the cycle. See the Plumbing
Options page.
A shock absorber (not supplied) should be installed on the incoming water line. This
prevents water hammer or hydraulic shock—induced by the solenoid valve as it
operates—from causing damage to the equipment. See the Plumbing Options page.
The machine has a pumped (pressure) drain capable of pumping waste water to
a height of 24” above the machine's drain pump and is supplied with a drain hose.
There must be an air-gap between/around the machine drain hose and the oor drain
or sink. The oor drain or sink must be at least 1.5 times larger than the machine drain
hose. If a grease trap is required by code, it should have a ow capacity of 12 GPM.
After installing the incoming water line and the drain line, slowly 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.
Take care not to confuse

Electrical and grounding conductors must comply with the applicable portions of the
National Electric Code ANSI/NFPA 70 (latest edition) and/or other electrical codes.
Refer to the data plate for machine operating requirements, machine voltage, total
amperage, and serial number.
Remove the back panel. Route power wires through indicated hole and connect to
power block and grounding lug. Install the service wires (L1 and L2) to the appropriate
terminals as they are marked below. Install the grounding wire into the lug provided.
It is recommended that “DE-OX” or another similar anti-oxidation agent be used on
all power connections.
Apply power to machine. Check 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 problems.
This is a commercial machine and reaches temperatures that can exceed those
generated by a residential machine. Surrounding countertops, cabinets, and ooring/
subooring material must be designed and/or selected with these higher temperatures
in mind.

WARNING! Some of the
chemicals used in
dishwashing might cause
chemical burns if they
come in contact with skin.
Wear protective gear when
handling these chemicals.
If any contact with skin
occurs, immediately
follow the treatment
instructions provided
with the chemicals.
The thermostats on this machine have been set at the factory. They should only be
adjusted by an authorized service agent.
If adjustments are necessary, click here for instructions.
The HT-E dishmachine is supplied with detergent and rinse-aid chemical feeder
pumps. The pumps have regulating screws to adjust the amount of chemicals being
dispensed. Locate the open ends of the chemical tubes and place each one in the
appropriate container. The tubes are labeled "Detergent" and "Rinse-Aid."
The bottom of chemical containers cannot be located any higher than 8” from the
oor. Chemical feeder pumps need priming when the machine is rst installed or if
the chemical lines have been removed and air was allowed to enter.
1. Verify that the proper chemical tube sti󰀨ener inlet is in the proper container.
2. Use the prime buttons located on the control panel to prime each pump. The
buttons are clearly marked DETERGENT and RINSE-AID.
3. To prime the pumps:
• Detergent - hold the DETERGENT button down until detergent is seen
entering the wash tank.
• Rinse-aid - hold the RINSE AID button down for two minutes.
A level machine is important to prevent any damage to the machine during operation
and to ensure the best possible results. The machine comes equipped with adjustable
bullet feet which can be turned using a pair of pliers. Since this machine is an
undercounter machine, it should be leveled as close as possible to the machine's
location before it is pushed under the counter.

INSTRUCTIONS
OPERATION
Before operating machine, verify the following:
1. Standpipe is seated in place and clean.
2. Strainers (shown removed for clarity) are in place and clean.
3. Wash and rinse arms are securely in place and rotate freely.
4. Chemical levels in chemical containers are correct.
1. Close the door.
2. Push the POWER button.
3. The power light will illuminate and the tank and booster will begin filling.
4. The rinse and wash lights will illuminate. Once the tank and booster have filled
and reached the minimum temperature, the rinse and wash lights will go out.
Proper ware preparation will help ensure good results and fewer re-washes. If not
done 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.

Detergent usage and water hardness are two factors that contribute greatly to how
e󰀩ciently this machine will operate. Using detergent in the proper amount can
become a source of substantial savings. A qualied water treatment specialist can
determine what is needed for maximum e󰀩ciency from the detergent.
1. Hard water greatly a󰀨ects 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.
2. Deposited solids from hard water can cause spotting that will not be removed
with a drying agent. Treated water will reduce this occurence.
3. Treated water may not be suitable for use in other areas of operation and it
could be necessary to install a water treatment unit for the water going to the
machine only. Discuss this option with a qualied water treatment specialist.
4. Operators should be properly trained on how much detergent to use per cycle.
Meet with a water treatment specialist and chemical supplier to discuss a
complete training program for operators.
5. This machine requires that chemicals be provided for proper operation and
sanitization. Contact a chemical supplier with any questions.
6. Water temperature is an important factor in ensuring the machine functions
properly, and the machine's data plate details what the minimum temperatures
must be for the incoming water supply, the wash tank, and the rinse tank. If
minimum requirements are not met, there is a possibility that dishes will not be
clean or sanitized.
7. 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.
