This document describes the SXD45/SXD50 series of warewashing and ice-making systems, focusing on their operation, maintenance, installation, and commissioning.

Function Description:

The SXD45/SXD50 is a professional warewashing machine designed for commercial use, capable of washing and rinsing items such as dishes and glasses. It operates through a series of automated cycles, ensuring items are cleaned and sanitized efficiently. The machine features a wash tank and a rinse boiler, with separate temperature controls to optimize cleaning and rinsing performance. It also incorporates dosing pumps for detergent and rinse aid, which are crucial for achieving effective results and preventing issues like spotting or foaming. The system can be configured for either gravity waste or pumped waste, depending on the installation requirements.

Important Technical Specifications:

  • Electrical Connections: The machine requires a 30amp or three-phase 3P+N (3x13A) or above electrical supply, as specified by the machine's identification plate. A suitably rated mains on/off switch must be fitted close to the machine.
  • Water Supply: It connects to a mains cold water hose (3/4 BSP) via a shut-off tap. For areas with hard water, an external water softener is recommended, requiring an additional hose connection.
  • Waste System:
    • Gravity Waste: Requires a waste outlet with a "running trap" or "P trap" to prevent odors. The trap level should be approximately 100mm below the machine's water level for proper drainage. The hose must be kink-free.
    • Pumped Waste: Connects to a waste standpipe approximately 400mm above the wash tank water level. The waste hose must be inserted using a high loop hook and should not be sealed into the standpipe, maintaining an "open to air" connection. A "running trap" or "P trap" is also required.
  • Temperature Controls:
    • Rinse Boiler Thermostat: Adjustable from 0-90°C, with a recommended setting of 86°C.
    • Wash Tank Thermostat: Factory set to 55°C.
    • Safety Overload Surface Thermostat: 110°C (normally closed).
    • Wash Tank Fitted Surface Thermostat: 42°C (normally open), connected only to the machine ready lamp.
  • Cycle Times: The machine offers selectable cycle times of 2 minutes or 3 minutes.
  • Dosing Pumps: Peristaltic dosing pumps for detergent (red tube) and rinse aid (clear tube) are adjustable to optimize chemical delivery.

Usage Features:

  • Preparation: Before operation, users must ensure the drain plug is firmly in place, the filter bowl is positioned correctly, and detergent and rinse aid supply tubes are submerged in sufficient product. The door must be closed, and the power switch pressed. The machine requires 30 minutes to fill with water and reach the correct wash temperature, indicated by the "Machine Ready" lamp.
  • Operation Cycle:
    1. Remove debris from items before loading them into the basket.
    2. Select the desired cycle time (2 or 3 minutes).
    3. Close the door and press the "Cycle Start" switch. The "Cycle Lamp" will illuminate.
    4. At the end of the cycle, the "Cycle Lamp" will turn off.
    5. Open the door and pull out the basket.
    6. Allow excess water to run off before removing items.
  • Controls: The front panel features a "Power Lamp," "Cycle Lamp," "Cycle Selection Lamp," and "Machine Ready Lamp" to indicate machine status. It also includes a "Power Switch," "Cycle Start Switch," and "Cycle Time Switch."
  • Dosing Pump Adjustment: The detergent adjustment is typically set to (4-5), and rinse aid to (2-3). The goal is to achieve 4mm to 6mm of foam on the wash tank water surface at the end of a wash cycle. Incorrect adjustment can lead to poor results, damage to the machine, foaming, cloudiness, or streaks.

Maintenance Features:

  • Routine Maintenance (End of Session):
    1. Turn off the power switch. Do not remove the filter bowl at this stage.
    2. Remove the drain plug to empty the wash tank. Machines with a drain pump will automatically pump out water.
    3. Collect and remove debris from the wash tank.
    4. Clean the wash tank, door surrounds, and hinges with an "Addis" type washing-up brush. Avoid chloride-containing cleaning solutions or abrasives.
    5. Remove, clean thoroughly, and replace the filter bowl. Prevent debris from entering the outlet hole.
    6. Regularly check and clean rinse jets and wash jets for debris or lime scale. This involves unscrewing the rinse arm nut and removing the rinse pin that holds the wash arm in place, then cleaning both thoroughly and reassembling.
  • Water Softener Regeneration: If an external water softener is fitted, it must be regenerated regularly. Ensure water valves are turned back on to supply softened water to the machine.
  • Service Calls: The manual explicitly states that service calls to rectify faults caused by a lack of routine maintenance will be charged for, and the warranty may be affected. This emphasizes the importance of adhering to the maintenance schedule.
  • Installation and Servicing: All installation and servicing must be carried out by qualified catering engineers trained for this type of machine to prevent electric shock risks and ensure proper operation.
