Now we’re almost finished with the installation. We have the water and the power connected, the final rinse temperature, and the wash and power rinse temperature thermostats set, the last thing we need to adjust is the vent hood adapter baffles. The adapter baffles need to be adjusted so it only draws in the steam that comes underneath the curtains while the machine is in operation. The EST-44 and 66” conveyors require 600 CFM total, 400 at the exit, and 200 at the entrance. Now to adjust the baffles. You’re going to require two 7/16” wrenches to do this procedure. You are going to close the baffles while steam is coming up, and you’re going to open them just enough to draw in the steam into the vent hood adapter. The vent hood adapter installed properly will overhang the exit of the machine or the entrance to draw in the steam. Once you’ve opened up the baffle, steam has been drawn in, then you use the rear wrench to tighten the baffle so you lock it into place. Once you’re done with the final rinse, you’ll move to the entrance of the dishwasher and repeat the process. We’ve completed setting the rinse vent hood adapter baffle and we’re going to repeat the process on the entrance side. Again, using a 7/16” wrench, on both the front and rear of the baffle, we’re going to open up the baffle just enough to draw the steam into the vent system. Once you have the steam being evacuated from the outside of the curtain, you’re going to use on this one, the front wrench to tighten down the baffle so it doesn’t move. Now that you have both baffles adjusted properly, only the steam will be captured that leaves the machine, which will retain the heat inside the dishwasher at all times. Now we have the installation almost completed. The water and power are connected; the temperatures are set, both for the wash, power rinse, and e-temp booster heater. The last adjustments that need to be made on the dish tables. Make sure when the tables are installed that they are always slightly angled back to the dishwasher to recover as much water on the table as possible. To do the final inspection to make sure your installation is complete, run your dish machine. Check your pressure, check your temperatures, make any final adjustments necessary. The wash tank thermostat should be set so the gauge reads between 155-160 degrees. The power rinse tank should be set so the gauge reads between 160-165 degrees. The final rinse in a high temp application should read between 180-195 degrees. In a low temp application, it should have the final rinse temperature between 145-150 degrees. Now we’re going to install the table limit switch on the clean side table. To remove the template located on the table limit switch, remove all the hardware and remove the template from the switch. This template is only used to align and drill the holes for the table limit switch in the clean side table. Place the template on the center of the clean side table, and mark your holes where they need to be located. Remove the template and drill the holes. Once the holes have been drilled, you’re going to take your table limit switch and remove the activator bar. For demonstration purposes, on this unit, I’ve already taken the bar off. Place the unit through the two holes that you pre-drilled using your template, re-install the activator bar onto the table limit switch, the table limit switch is now fully installed and it will interrupt the operation of the dishwasher when the wraps are on the clean table, stopping it from backing up into the dish machine. In the event you have a dish table that has a turn at the end, there is a whisker type table limit switch available upon request. This concludes the installation of the CMA EST-44 and CMA EST-66 inch conveyors. The similarities between these two machines are very, very, close, the connections between these two machines are almost identical, except you have one more prewashed motor in an EST-66 than you do in the EST-44. Both machine’s motors have thermal overloads in case they overheat, they will shut down and re-begin when they turn off. Congratulations, now your new EST-44 conveyor has been installed, and all procedures have been followed. As a final inspection, follow the check list that has been provided in the installation manual and should be checked off prior to activating the machine for operation. Check all electrical connections to insure they are tight and secure. Check all water, drain, and plumbing connections for leaks, tighten if necessary. Check final rinse arms; rinse jets spray should be straight up and down. Check wash pump rotation; make sure it is turning clockwise. Check the dishrack movement, conveyor arm, and bar, and conveyor dogs alignment. Check tray track guide-rail alignment through dishwasher, and alignment with tables. Check conveyor timer dipswitch settings, only switch number 6 should be in the on position for 32 seconds. Check wash tank temperature 150 degrees Fahrenheit minimum. Check power rinse tank temperature 160 degrees Fahrenheit minimum. Check final rinse temperatures, 180-195 degrees Fahrenheit for high temperature applications, and 140 degrees in low temperature applications. Check final rinse pressure 20 psi plus or minus 5 psi. Check table limit switch operation. If not installed, warranty will be voided. Check vent hood adapter baffles position to draw steam (optional). Keep baffles open to a minimum. Check and make sure the dishwasher is level. Check to make sure all curtains are in place. Read all labels, follow procedures. Review installation section before beginning the installation of the model EST-44 conveyor dishwasher. All installation procedures and guidelines should be followed during installation.
