INSTALLATION INSTRUCTIONS
Read these instructions carefully and completely before you install the machine. The installation
should be carried out by a qualified technician who is familiar with all local codes and ordinances for
electrical and plumbing connections. If a commercial dishwasher is being installed in this area for the
first time, most of the cabinet work, plumbing, and electrical has to be done before moving the
machine into place. In the case of replacing an old dishwasher, check the plumbing and wiring
connections before moving the new dishwasher into place. Reasonable access to and around the
dishwasher for service must be provided
Installation Instruction
Ecomiser SU-01 / SU-02 Manual – Rev. 06 Page 8 of 23

1. ELECTRICAL CONNECTIONS
Connect supply cable with a UL-listed strain relief bushing (if non-metallic cable is to be used).
A 208 - 230 volt, 60 Hz, 1 phase circuit is required for this machine. Despite the fact that the rating
plate shows 220 volts, the unit is designed to function properly on 208 volts to 230 volts.
1) Before working on wiring the machine, be sure the electrical power has been turned off at the
breaker/fuse box.
2) Electrical and grounding connections must comply with the applicable portions of the national
electrical code and/or other local electrical codes.
GROUNDING INSTRUCTIONS
This machine must be properly grounded Grounding instructions for a permanently connected
machine:
- This machine must be grounded to operate properly. It must be connected to a grounded metal,
permanent wiring system or an equipment-grounding conductor must be run with the circuit
conductors and connected to the equipment-grounding terminal or lead of the machine. When
grounding the machine, connect the green line to the terminal provided.
Figure 1-1 Main electrical supply connection
OVERVIEW OF INSTALLATION
The owner should contract with qualified personnel to move the appliance to the installation location,
unpack it, and prepare it for final utility connections. In most cases, local codes prevent the final utility
connections from being made by any party other than a licensed electrician and plumber.
NOTE
It is the responsibility of the owner to ensure that all aspects of the installation comply with all
applicable local and national codes.
NOTE
It is a good idea to inspect for any shipping damage before you proceed with the installation. If you
find any damage, you should report it to your dealer / freight company before accepting delivery.
2. WATER SUPPLY LINE CONNECTION
Before connecting the water supply hose, the line must be flushed clean of all debris, including (but
not limited to) pipe sealant, metal particles, solder, etc. This debris can damage to the machine.
- The water supply line could be connected to hot water or cold water and a shut-off valve should be
installed before connecting them.
- Water supply pressure should be under 40 psi and temperature should be kept at a minimum
140
℉
/60
℃
(SU-01) and 59
℉
/15
℃
(SU-02).Adjust water supply time to 1 gal per cycle, using the
water flow control valve inside the machine. Adjust so the fill indicating light stays on for 30 seconds.
Ecomiser SU-01 / SU-02 Manual – Rev. 06 Page 9 of 23

Figure 1-2 Fresh water connection
NOTE
In some cases, local codes dictate that water supply connections be made only by a certified
professional.
- Check that iron or other metal particles cannot contaminate the fresh water supplied to the machine.
- Check that the incoming water pressure is within the acceptable range for the machine (10 - 40 psi,
0.7 - 2.8 bars). It may be necessary to reduce the pressure.
- Check the incoming water temperature. Colder water will result in a longer preheat time (during
initial startup) and may extend the cycle time to allow the final rinse water to heat to minimum
180°F/82°C.
- Check the incoming water hardness. The Ecomiser SU-01 / SU-02 Models require a hardness of 4
grains per U.S. gallon or less. If over 4 grains the water should be treated.
- When connecting the customer-supplied water line to the fitting on the end hose supplied, pay
attention to prevent the hose from being twisted or broken.
3. DRAIN CONNECTIONS
- The Ecomiser SU-01 / SU-02 models contain a 1 1/2” (38mm OD) drain hose for end user’s
convenience.
- The Ecomiser SU-01 / SU-02 models are factory built with a drain pump. Recommended rough in
height is maximum 18” (457mm).
- Check that the end of the drain hose will empty into a drain with a minimum diameter of 1 1/2”
(38mm).
- Route the drain hose to the drain. In some cases a grease trap (supplied by others) must be fitted
into the wastewater line. If this trap is required for your installation, check that it is present.
Figure 1-3 Drain Connection
Max. Height 18”(457mm)
Ecomiser SU-01 / SU-02 Manual – Rev. 06 Page 10 of 23

NOTE
- No portion of a wall drain system may be higher than 18” (457mm).
- No part of the drain hose should be higher than 20” (508mm) from the bottom of the dishwasher.
- Failure to provide the proper drain connection height (maximum of 20” (508mm))above the
bottom of the dishwasher base) will result in improper drainage.
- After connecting the drain hose to main drain line, make sure all connections are watertight
4. DISPENSING SYSTEM CONNECTION
The Ecomiser SU-01 / SU-02 models are designed for use with a liquid rinse aid and detergent. The
Ecomiser SU-01 / SU-02 models equipped with liquid internal detergent and rinse aid pumps each
have each tube exiting the machine at the lower rear. These tubes can simply be attached to detergent
and rinse aid containers.
- Commercial (not a domestic) detergent must be used.
- Locate the red liquid detergent and blue liquid rinse aid tube at the lower rear of the machine.
Connect the tubes to the detergent and rinse aid container.

Ecomiser SU-01 / SU-02 Manual – Rev. 06 Page 17 of 23

The interior of the Ecomiser SU-01 / SU-02 models are made of quality stainless steel that has been
electro polished to produce the smoothest surface available. The smooth surface prohibits the
accumulation of dirt and bacteria inside the unit. If the water in your area is especially hard, however,
lime deposits could form inside the machine. If this happens, you can remove them by putting 1000cc
of scale removal product in the wash tank and running a normal wash cycle 10 times. In extremely
hard water areas you may need to repeat this process a few times to remove hard water deposits.
CLEANING THE STRAINER BASKET
For your convenience, we have placed the strainer within easy reach inside the tub. To clean the
strainer, wash it gently in hot, soapy water and rinse it thoroughly 1 to 2 times every day.
CLEANING THE DOOR
To clean the edge around the door, use only a soft warm, damp rag. To prevent penetration of water
into the electrical components, do not use a spray cleaner of any kind.
WARNING
Never use a spray cleaner of any kind on the control panel. You could damage the electrical
components. Never use abrasive cleaners or scouring pads on the outer surfaces because they will
scratch the finish. Also, some paper towels can scratch or leave marks on the stainless steel surface.
CLEANING THE IMPELLERS
Impellers may sometimes become clogged with hard water deposits. To remove them, grip the center
of impeller and wash it all over with soft rags. After removing all of the impellers, check to ensure
impellers revolve easily.
DE-LIMING
Lime scale deposits will occur over time on the interior of the machine if it is operated using a hard
water supply. The Ecomiser SU-01 / SU-02 models require that a de-liming or de-scaling process be
used to remove these deposits, as well as any accumulated food residue. When de-liming the interior
area, be sure to follow these guidelines.
- Use de-liming agents designed for use with commercial dishwashers.
- Follow the instructions for the de-liming agent that is used.
NOTE
After the de-liming process:
- Run the machine through 2-3 regular cycles and sanitize the interior thoroughly.
- Inspect the interior for any remaining de-liming agent residue. If residue is present, remove it using a
soft cloth and hot water; then, run the machine through one final cycle.
- Press the POWER OFF button. This will empty the tank, ensuring that any de-liming agent still in the
tank will be flushed out of the machine.

As with any new machine, it sometimes takes using it a few times to learn to operate it properly. If you
are having minor performance problems with your dishwasher, read this section before calling for
service. It may save you time and unnecessary expense.
POOR WASHING PERFORMANCE
- The dishes may not be loaded properly. Make sure that soiled surfaces are facing downward or
toward the center of the dishwasher. Also, make sure that the bowls, pots, etc., are not stacked so
closely that water can’t reach the soiled surfaces.
- Make sure you are using the appropriate program settings for the dirtiness of the dishware.
- An item may be obstructing the rotation of the impeller. With the rack loaded and in place, manually
turn impellers to ensure free movement.
- Dishwasher detergent should be fresh and stored tightly closed in a cool, dry place. Old or caked
detergent will not dissolve properly.
- Dishwasher detergent may be inferior. Try a different brand.
- If you have hard water in your area, try adding more detergent and increasing the amount of rinse
aid dispensed. Water hardness must be controlled to 4-6 grains for best results.
- Check that the impeller jets are not clogged.
POOR DRYING PERFORMANCE
- Make sure the rinse aid is enough.
- Do not overload the dishes and be careful to avoid nesting.
- Load items with concave bottoms tilted so as much water as possible will run off.
- Dishes washed in higher water temperatures will dry faster.
- Certain plastics may need to be towel dried. Always check the manufacturer’s suggested care
instructions before washing plastic in your dishwasher. Even dishwasher-safe items should be
loaded in the rack, away from the heating element.
- Check the amount of rinse aid is proper that it is fresh.
WASHING ITEMS
Ecomiser has no control over what is put in dishwasher once installed in a user’s place. You are
solely responsible for what you wash in your Ecomiser SU-01 / SU-02 models dishwasher. Most
common dishware items can be safely washed in an automatic commercial dishwasher. If you have
any doubts about a particular item, check with the manufacturer to see if it is dishwasher safe.
- Some high-acid foods can discolor plastic. You should rinse these items.
- When you load the dishware, be sure dishware is securely in place and will not fall over or strike
against each other during the wash.
- Load glasses between the tines, not straddling them.
- Move the rack in and out slowly to avoid slamming the dishware together.
- Make sure not to load dishware so high that the upper impeller could strike them.
- Do not overload the dishwasher.
STAINS AND DISCOLORATIONS
Stains or discoloration on dishware could be caused by a number of things:
- Too much iron or manganese in the water can cause yellow or brown marks on your dishware. You
should consider installing a water filtering system.
- Coffee and tea stains usually have to be removed by hand washing. Be sure to rinse these items
thoroughly before putting them in the machine so there is no bleach residue on the dishware.
