Answer:
Take the precautions below when a UC-15I Ice Maker is removed from service for an extended period of time or exposed to ambient temperatures of 32°F(0°C) or below, such as during the winter.
Follow these steps for indoor and outdoor units:
- Clean and sanitize the unit to prevent mildew growth.
- Disconnect the electrical power at the circuit breaker or service panel.
- Turn off the water supply.
- Drain water from the water trough by removing the drain tube and standpipe/overflow tube.
- Disconnect the incoming water supply line at the rear of the ice maker and allow it to drain.
- Remove the water filter.
- At the water pump outlet, disengage tube clamp teeth and remove clamp from tube and pump outlet, then pull tube up off of pump outlet.
- Remove the spray bar assembly and pour out any residual water.
- Ensure water is not trapped in any of the water supply or drain lines by using compressed air to blow out the lines.
- Use a spray bottle with a solution of 1 tablespoon (15 ml) sanitizer to 1 gallon (3.8 L) water and spray all interior surfaces. Do not rinse. Allow it to air dry.
- Block the door partially open when possible to provide air exchange and prevent mildew growth.
- For outdoor units in areas that receive snow, close the doors.
- Upon return, discard and replace the water filter with a new filter before startup.
