INSTALLATION & OPERATION INSTRUCTIONS
VISUAL INSPECTION: Before installing unit check container and machine for damage. A damaged container may be an
indication of damage to the machine. If there is any type of damage to both container and unit, do not throw away the container.
The dishmachine has been inspected at the factory prior to shipping and is expected to arrive in new, undamaged condition.
However, rough handling by carriers or others may result in damage to the unit while it is in transit. If such a situation occurs,
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 request that an inspection report be completed. Contact the carrier within 48 hours of receiving the
machine (to report possible freight damage) and the dealer from whom the unit was purchased.
UNPACKING THE DISHMACHINE: Remove the machine from the container and inspect it for any missing parts. If a part is
missing, contact manufacturer immediately.
LEVEL THE DISHMACHINE: The dishmachine is designed to operate while level. This is important to
prevent any damage to the machine during operation and to ensure the best results possible. The unit
is equipped with adjustable bullet feet which can be turned using a pair of pliers. Verify the unit is level
from front to back and side to side before making any electrical or plumbing connections.
PLUMBING THE DISHMACHINE: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 flushed of debris
prior to 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 water damage, are not the responsibility of the manufacturer.
A water hardness test should be performed to determine if the HTS-11 (scale prevention & corrosion control) needs to be
installed. If water hardness is higher than 5 GPG, the HTS-11 will need to be installed. Please contact manufacturer to purchase
the HTS-11.
CONNECTING THE DRAIN LINE: This dishmachine drain requires a minimum 2” NPT piping that
is pitched at least 1/4” per foot. There must also be an air gap between the machine drain line and
the floor sink or drain. If a grease trap is required by code, it should have a flow capacity of
5 gallons per minute.
WATER SUPPLY CONNECTION: Install the water supply line (1/2” NPT minimum) to the dishmachine
line y-strainer using copper pipe. It is recommended that a water shut-off valve be installed between
the main supply and the machine to allow for service. The water supply line must be capable of 20 ±5
PSI “flow” pressure at the recommended temperature as indicated on the data plate.
PRESSURE REGULATOR: In areas where the water pressure fluctuates or is greater than the
recommended pressure, it is suggested that a water pressure regulator be installed. This dishmachine
does not come with a water pressure regulator as standard equipment.
SHOCK ABSORBER: It is recommended that a shock absorber (not supplied) be installed in the
incoming water line. This prevents water hammer (hydraulic shock)—induced by the solenoid valve as
it operates—from causing damage to the equipment.
PLUMBING CHECK: Slowly turn on the water supply to the machine after connecting the incoming fill line and drain line.
Check for leaks and repair as required. Leaks must be repaired prior to operating the machine.

ELECTRICAL POWER CONNECTION: DISCONNECT ELECTRICAL POWER SUPPLIES & TAG OUT IN ACCORDANCE
WITH APPROPRIATE PROCEDURES & CODES AT THE DISCONNECT SWITCH TO INDICATE THE CIRCUIT IS BEING
SERVICED.
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 machine’s data plate for machine operating requirements,
machine voltage, total amperage & serial number.
Remove the connection box lid to install the incoming power lines. Install 1/2”
conduit into the pre-punched holes in the back of the connection box. Route the
power wires and connect to the power block and grounding lug. Install the service
wires (L1 and N) to the appropriate terminals as they are marked on the terminal
block. Install the grounding wire into the lug provided. Wires should be firmly secured
in place.
It is recommended that “De-Ox” or another similar anti-oxidation agent be used on
all voltage connections.
VOLTAGE CHECK: Ensure that the machine is off and apply power to the machine.
Check the incoming power at the terminal block and ensure it corresponds to
the voltage on the machine data plate. Do not run the dishmachine if the voltage
is too high or too low. Shut off the service breaker and mark it as being for the
dishmachine. Advise all personnel of the location of the service breaker. Replace
all covers and tighten the screws.

ELECTRICAL INSTALLATION INSTRUCTIONS
OPERATIONAL START-UP AND CHECK: Before proceeding with the start-up, verify the following:
1. Open the door and verify that the sump strainer is correctly installed in the sump.
2. Verify that the drain stopper is in position.
3. Check that the plugs are securely screwed into the ends of the wash arm.
4. Check that the wash arm is securely screwed into the stationary base and that it rotates freely.
5. Check the levels in all chemical containers and replace if necessary.
INITIAL START-UP PROCEDURE:
1. Turn on dishmachine:
a) Turn on the incoming power to the machine at the circuit disconnect box.
b) Turn on the dishmachine by pressing the ON/OFF button. The red light will come on.
c) Check voltage at incoming terminals L1& L2. The voltage measured at these points should match data plate voltage.
d) If voltages are in required range, close the control box cover.
2. Fill the rinse booster heater with water:
a) Before the heater element can be energized, the rinse booster heater must be initially filled with water. Damage to the
heater element will occur if the element is not submerged in water. To initially fill the booster heater with water:
i) Press and hold the FILL button to turn on the incoming water solenoid valve. Continue holding the button until water is
heard entering the wash chamber through the airgap, then release the button. The rinse booster heater is now filled
with water.
ii) Turn off the unit by pressing the on/off switch.
3. Enable heater element:
a) For the initial start-up only, the heater element must be enabled. The machine is shipped from the factory with the heater
element disabled. This is done to ensure that the heater element is not damaged by energizing the element without the
element being submerged in water. To enable the heater element:
i) Remove the booster heater cover panel.
ii) Connect the tagged white/blue wires.
iii) Replace heater cover.
iv) Press the on/off switch, heaters will energize to maintain booster heater temperature.
Note: Water must be in the sump while the machine is running to avoid running the pump dry and causing damage to the pump
seal.
4. Adjust dishmachine fill level:
a) If the water level is not between the lines on the drain standpipe, it will require adjustment. Check to ensure that the
recommended water pressure is being supplied to the machine (20 ±5 PSI is required). If the water pressure is correct,
the electronic timer will need adjustment. Use the following steps to adjust the fill time.
i) Open control box cover.
ii) Adjust fill time as per instructions found in this section.
iii) Open and close the door to run a cycle, then check the water level. Adjust as necessary then close the
control box cover.
NOTE: The machine must run a complete cycle to drain and fill. If the machine is not allowed to drain, the water will build up
inside the tub. After the initial fill, the rinse water for the current cycle will become the wash water for the next cycle.
The dishmachine is now ready to proceed with dishwashing.

CHEMICAL SOLUTION IS TOO STRONG. SEE A CHEMICAL PROFESSIONAL
TO ENSURE THE DISPENSER IS SET UP CORRECTLY.
This equipment is not recommend for use with deionized water or other aggressive fluids.
Use of deionized water or other aggressive fluids will result in corrosion and failure of materials and
components and will void the manufacturer's warranty.
TO PREPARE CHEMICAL FEEDER PUMPS FOR OPERATION:
The Delta 5 dismachines are supplied with detergent, rinse
additive and sanitizer dispensing chemical feeder pumps. Locate the open ends of the chemical tubes with the tube stiffeners
and place each one in the appropriate container.
Red Tubing = Detergent Blue Tubing = Rinse Aid White Tubing = Sanitizer
PRIMING CHEMICAL FEEDER PUMPS: Chemical feeder pumps need priming when the machine is first installed or if for
some reason the chemical lines have been removed and air is allowed to enter.
CAUTION: Water must be in the sump and wash tank prior to the dispensing of chemicals.
Sanitizer in concentration is caustic and may cause damage without dilution.
1. Verify that the proper chemical tube stiffener inlet is in the proper container.
2. Use the prime switches located on the control panel at the bottom of the unit to prime each pump.
The switches are clearly marked as to what chemical feeder pump they are assigned to.
3. To prime the pumps, hold the switch in the momentary position until chemical can be observed entering the sump.
4. Detergent is dispensed as required during the wash cycle by the universal timer. The amount of detergent may need to be
increased or decreased depending on water quality and type of detergent.
5. Rinse additive is dispensed as required into the final rinse. The amount of rinse aid may need to be adjusted depending on
water hardness and results.
6. Sanitizer (either chlorine or iodine) is dispensed into the final rinse. The amount of sanitizer may need to be adjusted
depending on the concentration and type of sanitizer used.
7. Please refer to the next page for instruction on adjusting the chemical feeder pumps on the universal timer.
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.

SECTION 2: INSTALLATION & OPERATION INSTRUCTIONS
CHEMICAL DISPENSING EQUIPMENT
DETERGENT CONTROL: Detergent usage and water hardness are two factors that contribute greatly to how efficiently this
dishmachine will operate. Using detergent in the proper amount can become a source of substantial savings. A qualified water
treatment specialist can relate what is needed for maximum efficiency from the detergent.
1. Hard water greatly affects the performance of the dishmachine, 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 may be necessary to install a water treatment
unit for the water going to the dishmachine only. Discuss this option with a qualified water treatment specialist.
4. Dishmachine operators should be properly trained in how much detergent is to be used per cycle. Meet with a water
treatment specialist and detergent vendor to discuss a complete training program for operators.
5. Certain dishmachine models require that chemicals be provided for proper operation and sanitization. Some models
may require the installation of third-party chemical feeders to introduce those chemicals to the machine. The manufacturer
does not recommend or endorse any brand name of chemicals or chemical dispensing equipment. Contact a chemical
distributor for questions.
6. Some dishmachines come equipped with integral solid detergent dispensers. These dispensers are designed to accommodate
detergents in a certain-sized container. If applicable, relate this to a chemical distributor upon first contacting them.
7. Water temperature is an important factor in ensuring that the dishmachine 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.
8. Instruct dishmachine 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—such as a failed heater—or could indicate that the hot water
heater for the operation is not up to capacity and a larger one may need to be installed.
