This document provides comprehensive information for the installation and maintenance of Alliance Laundry Systems Washer-Extractors, specifically Barrier Washer models. It covers safety guidelines, technical specifications, installation procedures, and maintenance instructions to ensure proper and safe operation of the machinery.
Function Description
The Washer-Extractors are designed for industrial laundry applications, including hotels, hospitals, nursing homes, and prisons. They are intended for washing textiles and are not suitable for domestic use or for washing items other than suitable linen (e.g., polymers, machine parts, automotive parts, or other ferrous materials). The machines are equipped with various features for efficient and safe operation, including a drum for washing, an extraction function, and options for hot water or electrical heating. Some models may include a weighing system for optimized load management and hygienic barrier placement for clean and dirty side separation.

Usage Features
- Hygienic Barrier: The machines are designed for placement into a hygienic barrier, separating the loading (dirty) side from the unloading (clean) side.
- Door Lock: Features an automatic door-lock system. Emergency unlocking is possible in case of power blackout, with specific instructions provided.
- Liquid Soap and Chemical Injection: Provisions for connecting external dosing of liquid soaps and chemical injection supply systems are available.
- Tilting Functionality: Some models may include a tilting function for easier unloading, requiring operators to stand sideways during activation.
- Safety Vibration Switch: Equipped with vibration switches to monitor and adjust for out-of-balance loads, enhancing safety and preventing damage.
- Water Inlet Connections: Supports hot and cold water connections, with filter devices to prevent particles from entering the machine.
Maintenance Features
- Daily Maintenance: Includes cleaning soap hoppers, removing foreign objects from the drum, cleaning the door seal, wiping down the machine, checking water/steam inlets for leakage, and airing out the machine by opening the door.
- Three-Month Maintenance: Involves checking bearing housing for leakage, drain valve functionality, belt tension, bolt tightness, hoses and connections for leaks, and ensuring control components are protected from moisture and dust. For electrically heated machines, contact tightening of heating elements and power terminals should be checked.
- Six-Month Maintenance: Requires cleaning water inlet filters and lubricating rods on the spring unit.
- Lubrication: Specific instructions are provided for lubricating bearings and sealing rings every six months, including the type of grease and procedure.
- Belt Replacement and Adjustment: Guidelines for checking and adjusting belt tension on new machines, after replacement, and periodically (every 6 months or 1000 operation hours).
- Washer Fuses: Instructions for replacing blown fuses with the correct values, emphasizing not to use higher-rated fuses without identifying the cause of failure.
- Troubleshooting: Provides guidance on unlocking the door lock in emergencies and refers to the Programming Manual for error indications. A list of recommended spare parts is also included.
