This guide provides essential instructions for the installation and initial startup of the CMA Dishmachines 180UC-3. Warning: All electrical and plumbing connections must be performed by a qualified service technician in compliance with all applicable Federal, State, and Local Health, Electrical, Plumbing, and Safety codes.
Installation and Plumbing
Proper installation is critical for the machine to function correctly. Follow these steps:
- Drain Hose: Connect the drain hose to the wall or floor drain. The hose must not be higher than 22 inches from the floor. Ensure a 1-inch air gap between the drain hose and the drain.
- Water Inlet: Connect the machine to a hot water source. The recommended minimum temperature is 140°F.
- Leveling: Adjust the leveling legs to ensure the dishmachine is level front-to-back and side-to-side.
- Electrical: Connect the hard-wire three-wire power supply according to local codes.
Chemical Setup
The machine requires chemical dispensers for detergent and rinse aid:
- Insert the tube stiffener with chemical tubing into the corresponding chemical containers.
- Ensure the red and blue tubes are connected to the correct dispensers as indicated on the rear view diagram.
Initial Startup and High-Limit Switch
Before the first use, you must connect the safety switch:
- Locate the booster high-limit switch behind the front panel.
- Ensure the power supply is turned off.
- Reconnect the factory-unplugged wire to the booster high-limit switch. This is required to prevent heating element damage.
- Press the power switch to the ON position.
- Listen for water spraying into the machine. Check the wash tank for water; if empty, repeat until the tank is full. The installer is responsible for adjusting the fill timer.
Daily Operation
Follow these steps for daily use:
- Press the power switch to ON. The machine will automatically fill the wash tank.
- Allow approximately 10 minutes for the wash tank temperature display to reach 160°F.
- Turn the power supply back on and allow the machine to heat up for about 10 minutes.
- Push the start switch to begin the cycle.
- Observe the "Rinse Cycle" (the last 12 seconds of the cycle). The temperature must be a minimum of 180°F.
Adjustments
If the rinse temperature is insufficient, you can adjust the booster thermostat. Turn the adjustment stem on the booster thermostat clockwise to increase the temperature.
