2. Getting Started
2.1. Introduction to CMA Model EST-44
The EST is designed to give maximum cleaning in 44 inches. It represents the cleaning power
of machines twice its length. The curtains incorporated in the dishwasher minimize the transfer
of water from tank to tank during the wash and sanitizing procedures.
The energy costs for running the new EST -44 have been greatly reduced, by the introduction of
our new Stage Washing Process. The EST-44 Conveyor dishwasher lowers gallon/rack
ratings and is directly related to CMA's new Power-Rinse Stage that has been introduced.
The EST-44 new Re-circulating Wash and new Power-Rinse Stage greatly reduce the
amount of chemicals being used, thus adding a significant cost reduction and energy
efficiency to its' operation.
The EST -44 can be used as a high or low temperature dishwasher, with the new wash tank and
power rinse tank designs, both having their own re-circulating pumps. The Power Rinse Stage
provides a fresh cleansing rinse, before the dish rack advances into the Power Rinse and sh
Water and Sanitizing Rinse Stages.
The initial-fill water and the final rinse water that is supplied to the EST -44 must be a minimum of
140
°
F, in low-temperature applications, while high-temperature machines will require two water
lines; one at a minimum water temperature of 140
°
F to fill the dishwasher, and the second with a
minimum of 180
°
F for the final rinse. With the introduction of the new optional E-Temp Booster
Heater, it will be oered fully integrated to the dishwasher.
The EST -44 also features a stainless steel scrap accumulator tank and tray, which must be
emptied on a periodic basis, as necessary. The EST machine is designed to deliver 0.49 gallons
of fresh rinse water for each rack. This water flows from the rinse and power-rinse tanks into the
wash tank, and then overflows into the scrap tray, carrying any debris that may have fallen into
the wash tank, thereby providing a much cleaner environment for the washed and rinsed dishes.
If preferred, there are also options such as a Corner Feed System, optional Vent Hood Adapters,
Exhaust Fan Control Circuits and a Drain Tempering Kit. CMA also oers a full line of other
machine accessories, including stainless steel dishtables. (See equipment catalog)
DISCLAIMERS
CMA 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 leer), or, any person or company conducting e installation of the CMA equipment, revise e
insllation procedures or alter the insuctions in any manner, the CMA warranty becomes void. If, due to the improper
installation of CMA equipment, this equipment ceases to operate properly or aects other pa of the CMA dishwashing
equipment, in that the other par 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 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 nd
that most, if not all, commercial dishmachines have been programmed with auto-lling features that require quick filling, with a
designated limited time.
CMA endorse, and highly recommends, the standard "tank" style water heaters, sized prorty to handle each paicular
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 ow of
adequate hot water supplied to the dishmachine. If the facilities' ''tank" style water heater is marginal in size, CMA recommends
installing a proper size Hatco Booster Heater, a CMA's E-Temp 40 or 70-degree-rise Booster Heater (that can be installed on CMA
Conveyors), or a CMA Temp-Sure Booster Heater (for door and undercounter dishmachines). All are designed to adequately
achieve results.
Impoant: Make sure incoming power supply corresponds to the voltage listed on the data plate. If the voltage is too low (206V or
less), the heating elements will not reach desired temperature specied by manufacturer, and performance will compromised.
The heating element needs to be sized according to the facilities available volge, which must noted on your purchase order
to CMA for a special dishmachine. Special lower voltage higher kilowa heaters are available upon request.
Make sure a fused disconnect switch or circuit breaker (not supplied) is installed in the electrical service lines supplying this
dishwasher and should meet the requirements of your local electrical code.

2.2.4. Scrap Tray Assembly Installation
The Scrap Tray Assembly and Overflow Chute, which were shipped inside the machine, can
easily be installed by executing the following steps: Figure 2.2.4 below illustrates the assembly,
as it would appear for a Left-to-Right machine – (a Right-to-Left machine would simply be the
mirror image).
Caution:
1. For proper spacing, the SS flat washer must not be located between the head of the truss
head bolt and the inside of the machine.
2. The Illustration below shows the correct placements of the scrap trap holder. Do not
install upside down, otherwise water deflection takes place.
Figure 2.2.4
1. Remove items from their packaging and verify that all “installation hardware” was included.
2. Secure the scrap trap holder to the dishmachine by using the four ¼-20 X ½” Hex Head
Bolts, the ¼” SS Flat Washers, and the ¼”-20 Nylon Lock Nuts that were provided.
3. Set the scrap trap body—with the scrap trap drawer inserted—into position on the scrap trap
holder. (Attach the drain as specified in Section 2.2.3)

2.2.6. Wash Pump Assembly and Impeller
The standard wash pump motor is three-phase and can operate clockwise, as well as counter-
clockwise; the Nylon Lock Nut used to hold the impeller in place (See Figure 2.2.6), is very
important. When servicing the Wash Pump Assembly and replacing the seals, make sure it is
secured properly; otherwise, if the motor turns the wrong direction, the impeller may spin-off the
motor shaft causing damage to the impeller.
Note: ALWAYS CHECK THAT THE DIRECTION OF THE MOTOR ROTATION IS CLOCKWISE,
WHEN REINSTALLING THE WASH PUMP. IF THE MOTOR IS TURNING COUNTER-
CLOCKWISE, EXCHANGE L1 AND L3 WIRES ON MAIN CONTACTOR
Figure 2.2.6
Note: The Nylon Lock Nut indicated by the arrow in Figure 2.2.6 must be removed before
attempting to remove the water pump impeller.

2.2.11. (Optional) E-Temp Booster Heater
*
The Optional E-Temp Booster Heater can only be ordered with a dishwasher, already installed at
the factory; it cannot be installed in the field. The E-Temp Booster heater will be fully integrated
into the EST-44 conveyors’ plumbing system. It will require its’ own power supply of 208 volts to
240 volts, in single-phase or three-phase. The unit can be specially ordered as a 480-volt unit, in
three-phase only; temperature is available in a 40° rise or 70° rise. The E-Temp Booster heater
contactor is located in the EST-44 Main Control Box (See item 7, page 6).
Note: E-Temp heater is shipped on the machine empty to prevent freezing. When machine
is powered up for the first time, the booster heater must be filled by pressing and holding
rinse switch to prevent heater damage.
Note: 70° degree rise E-temp Booster Heater is only available in Three-Phase.
*
