SECTION 2: INSTALLATION/OPERATION INSTRUCTIONS
INSTALLATION INSTRUCTIONS
VISUAL INSPECTION: Before installing the unit, check the container and machine for damage. A damaged container is an indi-
cator that there may be some damage to the machine. If there is damage to both the container and machine, do not throw away
the container. The dishmachine has been inspected and packed at the factory and is expected to arrive to you in new, undam-
aged condition. However, rough handling by carriers or others may result in there being damage to the unit while in transit. If
such a situation occurs, do not return the unit to Ecolab; instead, contact the carrier and ask them to send a representative to
the site to inspect the damage to the unit and to complete an inspection report. You must contact the carrier within 48 hours of
receiving the machine.
UNPACKING THE DISHMACHINE: Once the machine has been removed from the container, ensure that there are no miss-
ing parts from the machine. This may not be obvious at first. If it is discovered that an item is miss-
ing, contact Ecolab immediately to have the missing item shipped to you.
LEVEL THE DISHMACHINE: The dishmachine is designed to operate while being level. This is
important to prevent any damage to the machine during operation and to ensure the best results

when washing ware. The unit comes with adjustable bullet feet, which can be turned using a pair of
channel locks or by hand if the unit can be raised safely. Ensure that the unit is level from side to
side and from front to back before making any connections.

PLUMBING THE DISHMACHINE: All plumbing connections must comply with all applicable local, state, and national plumb-
ing codes. The plumber is responsible for ensuring that the incoming water line is thoroughly flushed prior to connecting it to
any component of the dishmachine. It is necessary to remove all foreign debris from the water line that may potentially get
trapped in the valves or cause an obstruction.
CONNECTING THE DRAIN LINE: The drains for the ES-2000/ES-4000 dishmachines are gravity discharge. All piping from
the 2" MNPT connection on the waste accumulator must be pitched (1/4" per foot) to the floor or sink drain. All piping from the
machine to the drain must be a minimum 2" NPT and shall not be reduced. 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: Ensure that you have read the section entitled "PLUMBING
THE DISHMACHINE" above before proceeding. Install the water supply line (3/4" pipe size min-
imum) to the dishmachine line strainer using copper pipe. It is recommended that a water shut-
off valve be installed in the water line between the main supply and the machine to allow access
for service. The water supply line is to be capable of 20±5 PSI "flow" pressure at the recom-
mended temperature indicated on the data plate.
NOTE: The optional Vapor Vent system must be connected to the COLD water line.
Incoming Plumbing Connection
In areas where the water pressure fluctuates or is greater than the recommended pressure, it is suggested that a water pres-
sure regulator be installed.
Do not confuse static pressure with flow pressure. Static pressure is the line pressure in a "no flow" condition (all valves and
services are closed). Flow pressure is the pressure in the fill line when the fill valve is opened during the cycle.
It is also recommended that a shock absorber (not supplied) be installed in the incoming water line. This prevents line 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 the incoming fill line and the drain line have been
installed. Check for any leaks and repair as required. All leaks must be repaired prior to placing the machine in operation.
