air heater and suction solenoid. See page 6 for details.
□ Set suction pressure to a 24° equivalent. Ensure stable temperature.
□ Ensure the TXV superheats are within specs.
□ Ensure the controller settings are per the specs for setpoint, differential and defrost (see pg 5).

Miatech Responsibility
□ Remove rear skirt and slide the fogger system into the tray located under the case.
□ Mount the heated nozzles into designed position under the discharge air grill.
□ Rout the water, air and heater wires through the provided case drop.
□ Connect the water and air lines to the fogger system. Be sure an appropriate amount of slack is
available to service the nozzles. The water lines must not contact the cold suction refrigeration
lines. Freezing could occur and the system will be inoperable.
□ Remove the case rear panel with the case controller to gain access to the rear raceway (pg 7).
□ Ensure that the provided time clock (pg. 7-8) is set to local time. The factory default is CST.
□ Ensure that the provided time clock (pg. 7-8) is programmed to the store's display hours. The
factory default is 10pm – 6am system off time. Check with the store's personnel to understand if
the case product will be unloaded and loaded, and if so, at what times. Adjust the time clock
accordingly. If the case is to remain loaded overnight, the fogger system must run continuously
and the time clock should be overridden (see pg 8).
□ Plug the fogger system into the switched GFCI socket marked "Fogger System" (see pg 4).
□ Plug the nozzle heater(s) into the GFCI marked "Fogger Heater System" (see pg 4).
□ Turn the fogger system on with the rocker switch mounted on the case control panel. The rocker
switch light should illuminate. If it does not, see page 7.
□ Adjust the fogger system to the settings on page 5.
□ Observe for proper operation with the discharge grills removed. Observe spray pattern. The
nozzle spray pattern should shoot into the crumb tray parallel to the bend lines of the crumb tray.
□ Test the RO filter and ensure the proper reduction of TDS between the inlet vs outlet of the RO
system.
□ Seal the case through-hole for the air and water lines.
□ Reassemble deck pans, rear skirt, and rear panel.
□ Ensure the discharge air grills are properly positioned inside the case and/or line-up. See the
