5. Chemical Feeder
The peristaltic pumps are assembled and included within the machine.
Note: Use only commercial-grade detergents and rinse aids recommended by your chemical
professional. Do not use detergents and rinse aids formulated for residential dishwashers.
Low Temperatures chemical-sanitizing dishmachines must not exceed 6% sodium hypochlorite solution
(bleach) as the sanitizing agent. Higher levels may damage stainless or components.
Follow the directions precisely that are on the litmus paper vial and test the water on the surface of the
bottom of the glasses. Concentration should be 50 p.p.m. minimum to 100 p.p.m. maximum. If
concentration is incorrect contact your chemical supplier.
6. Activating Machine
The machine is equipped with a prime switch to activate the peristaltic pump at any time the master
switch is “ON”.
Following the completion of the installation, always fill the machine with water before the machine is
started.
 Hold the fill button until the water level is approximately ½” to ¾” below the overflow hole in the
PVC standpipe. This water level should be approximately even with the bottom edge splash guard
in sump area of machine.
 Activate the prime switches for the three chemical pumps until the product is discharging into the
sump.
 To start the machine, close the doors and the machine will cycle automatically.
The amount of product delivered by each cam is controlled by changing the opening in each cam. When
the micro switch rides down into the cam, the peristaltic pump motor begins to rotate. It will continue to
rotate until it rides up out of the groove. Therefore, to extend the amount of product delivered to the
machine, open the groove. To reduce the amount of product delivered to the machine, close the groove.
Cams are slip fit. A cam adjustment wrench is provided, but the cam can be adjusted with a small
screwdriver or the edge of a table knife.
Technical personnel are available during normal business hours should you, as an installer, have any
questions. We are available to serve you at 800-854-6417.
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 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 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 DOES endorse, and highly recommends, the standard “tank” style 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, 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.
