2.2.7. Machine Start-Up Procedures for High Temp machines.
1. Place the scrap baskets over the wash tanks.
2. Secure the wash & rinse arms and check the free-spin.
3. Open the control panel and select ‘normal” toggle switch position.
4. Adjust the rinse pressure to 20 PSI flow pressure using the regulator and the gauge provided on machine. a. Turn the power switch to the “Off” position. b. Close doors and press “Auto Fill” rocker switch;the water overflows into the scrap trap. c.
Turn the power switch to “on” position.
SEE NOTE FOR BOOSTER HEATER
BELOW. d.
While holding “flush” toggle switch, to activate the water solenoid, adjust the pressure regulator until the gauge reads 20 PSI. NOTE: Booster heater is filled during this procedure.
5. Connect the detergent and rinse dispenser to the power block supplied & labeled inside the control panel (208-220) volt.
6. Remove the plug from the mixing chamber and install the rinse injection fitting.
7. A 7/8” chemical probe hole is provided in the wash tank behind wash tank heater cover.
8. A 7/8” detergent fitting hole is provided in the wash tank behind the machine.
9. Check the machine operating temperatures. Adjust if necessary. a. After the machine has warmed up for five to ten minutes (5 – 10 min.), observe the wash and rinse temperatures. The wash temperature must be 155°F

minimum. The rinse temperature must be 180°F minimum. If necessary, adjust the temperatures by removing the panel in front of the respective heater and turning the adjustment stem clockwise to increase.
NOTE: Rinse water temperature must be observed during the rinse cycle.
10. Check all water and drain fittings for leaks.
11. Install the wall chart and instruct the machine operator on the proper cleaning and operation of the CMA-180.
Caution: Booster Heater
Booster heater is shipped on the dishmachine empty to prevent freezing. When the machine is powered up for the first time, the booster heater must be filled immediately to prevent damage to the heating element. See Section 2.2.7 (4d.)
To prevent booster heater element damage, CMA has removed a wire from the high limit switch. When initially filling of a newly installed dishmachine, you must fill the booster tank prior to connecting the removed wire. When water is observed entering the wash tank this indicates the booster tank is full and removed wire can be connected. Failure to follow these important instructions will destroy the heating element because of dry -firing.
