INSPECTION
Do not throw away
packaging if damage is
evident!
UNPACKING
PLUMBING
The plumber must ush
the incoming water line!
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.
WATER SUPPLY CONNECTIONS:
WATER HARDNESS
HIGHER THAN 3 GPG
i
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.

ow pressure!
SHOCK ABSORBER
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.
CONNECTING THE
DRAIN LINE
PLUMBING CHECK
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.
Drain Hose
Air-gap
≤24”
Floor Drain
or Sink
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.

DETERGENT
CONTROL
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
i
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.
