Note: The required flowing water pressure to the dishwasher is 15-65 PSIG. If pressures higher than 65 PSIG are present, a pressure regulating valve must be installed in the water line to the dishmachine (by others). If flowing pressure is lower than 15 psi, improper machine operation may result.

2. Getting Started
2.1.Introduction to the EST-FL Front Loader
The EST-FL low temperature Front Loader Dishmachine is safe, economical and easy to operate with its “Auto Start/Stop”, and it uses only 1.09 gallons of water per cycle. The EST-FL Front Loader Dishmachines top mounted controls houses built-in chemical pumps and a deliming system that assures proper chemical usage. Its integrated scrap tray prevents food soil from entering the drain system. The EST-FL can be run at a rate of 40 racks/160 covers per hour and its all stainless steel construction assures longevity.
The EST-FL Front Loader; features an optional fully intergraded hot-water assurance storage tank, to insure consistent water temperature is always being supplied to the dishmachine. The attributes of this dishmachine are always taken into consideration by our well-trained sales representatives prior to the order being placed.
This manual is structured to provide a complete reference guide to the EST-FL Front Loader Dishmachine. It is presented in a manner that all levels of users will be able to comprehend and use as an effective tool in supporting the operation and maintenance of the dishmachine. The function of the dishmachine itself is mostly automatic and takes little training to put into operation. The Operation section also includes diagnostic considerations (troubleshooting) for the dishmachine when problems occur.
The first section explains how the dishmachine is packaged and what to look for when receiving the machine. After unpacking the dishmachine, this manual explains how to install and set up the dishmachine for use. Requirements are given for plumbing, wiring, and space considerations.
Guidance is also given for installation to ensure that the machine will be able to run at optimum efficiency. The Operation section of the manual may be used for instruction and procedures when required. Parts Manual and Electrical Diagram—have the parts lists with exploded view drawings and the wiring diagram for the dishmachine.
CMA Dishmachines warrants the workmanship of the dishmachine. We are committed to providing the best dishmachines and customer service in the warewashing industry and your feedback is welcome.
DISCLAIMERS
CMA Dishmachines expressly disclaims any and all warranties, express or implied, relating to the installation of any and all CMA equipment that is installed by chemical dealers, contracted servicers or third party servicers to CMA equipment. If the installation instructions are not followed exactly (to the letter), or, if any person or company conducting the installation of the CMA equipment, revise the installation procedures or alter the instructions in any manner, the CMA warranty becomes void. If, due to the improper installation of CMA equipment, this equipment ceases to operate properly or affects other parts of the CMA dishwashing equipment, in that the other parts become defective, the CMA warranty becomes void. CMA will not be liable or responsible or warrant CMA equipment, due to improper installation of any CMA model dishwasher.
CMA Dishmachines does not endorse “Tankless On-Demand” water heaters for use on CMA Dishmachine products. On most applications, the volume of hot water required for commercial dishmachines exceeds the capacity of these types of heating sources. You will find that most, if not all, commercial dishmachines have been programmed with auto-filling features that require quick filling, with a designated limited time.
CMA Dishmachines does endorse, and highly recommends, the standard “tank” style hot-water heaters, sized properly to handle each particular facility with their water heating requirements. A “tank” style water heater stores and supplies a large capacity of preheated water before providing hot water to the dishmachine. To meet required health codes, there must be a reliable and consistent flow of adequate hot water supplied to the dishmachine. If the facilities’ “tank” style water heater is marginal in size, the option on-board hot-water assurance storage tank can be used, which can be fully intergraded into the footprint of the dishwasher

Getting Started
2.2.Receiving and Installation
The dishmachine is shipped from the factory in a corrugated box on a wooden pallet. The installation guidelines give a systematic procedure for setting up the machine.
Start by removing the dishmachine from the box, and remove all the packaging materials. Unwrap the machine, and check for the following components:
Inside the wash tank is a plastic bag with one control box key and a cam timer wrench.
Tube stiffeners must be used to prevent the feed tubes from curling inside the chemical pail and sucking air. These are located on the outside of the machine with the chemical tubing already installed into the stiffeners. The ends of the chemical tubing have been flared so that the tubing will not pull out of the stiffener. Red is for detergent, white for sanitizer, and blue for rinse aid.
2.2.1. Electrical*
Prior to installation make sure the electrical supply is compatible with the specifications on the machines data plate.
The EST-FL Dishmachine must be hard wired directly to a dedicated 115 VAC, 60Hz circuit equipped with proper circuit protection. The main power switch is at the top-right side of the control box.
WARNING: Electrical and grounding connections must comply with the applicable portions of the National Electrical Code and/or other local electrical codes.
Note: For supply connections, use copper wire only rated at 90 degree C minimum.
2.2.2. Plumbing*
The water supply connection is made with a ½” hot water line to the water supply inlet on the top of the dishmachine. The water supplied to the machine is recommended to be 140° F. The time necessary to deliver water to the machine is controlled by the number four cam.
The EST-FL Front Loader Dishmachine has a 2” drain. The following section explains how to connect the drain.
* Electrical and plumbing connections must be made by a qualified person who will comply with all available Federal, State, and Local Health, Electrical, Plumbing and Safety codes
