the lifters are perforated on the top so that water can cascade over the goods and wet them quickly. This reduces water consumption as water is picked up at the cylinders lowest point and lifted and splashed over the goods at the highest point as the cylinder rotates. A stainless steel door is provided for loading and unloading. A door lock system prevents operation of the machine when the door is open. The door is locked during operation utilizing an air cylinder and a manual latch for safety reasons.

Chapter 5 Installation 5.1 Receiving Inspection Upon receipt of the equipment, visually inspect for shipping damage and note any damage with the carrier before signing the shipping receipt, or advise the carrier of the damage as soon as it is noted. If damage is discovered, a written claim must be filed with the carrier as soon as possible. Note: Warranty is VOID unless the equipment is installed according to instructions. The installation must comply with the minimum requirements listed in this manual.
Before servicing any equipment, make certain it is disconnected from the electrical power source. Never allow operation of the machine when any safety device is malfunctioning. Never bypass safety devices. Never insert hands or objects into basket until it has completely stopped. Doing so could result in serious injury. 1. When the washer is energized electrically and in operation, the loading door must be locked in the closed position.
Never operate the machine with a bypassed or disconnected out-of-balance switch. Operating the machine with severe out-of-balance loads could result in personal injury and serious equipment damage. Do not place volatile or flammable fluids in any machine. Do not clean the machine with volatile or flammable fluids such as acetone, lacquer thinners, enamel reducers, carbon tetrachloride, gasoline, benzene, naphtha, etc. Doing so could result in serious personal injury and/or damage to the machine. 5.2.
Replace all panels that are removed to perform service and maintenance procedures. Do not operate the machine with missing guards or with broken or missing parts. Do not bypass any safety devices. 5.2.4 Machine Location 1. Foundation. The concrete floor must be of sufficient strength and thickness to handle the floor loads generated by the machine at high extract speeds. 2. Service/ Maintenance Space. Provide sufficient space to allow comfortable performance of service procedures and routine maintenance.
Always disconnect power and water supplies before a service technician performs any service procedure. Where applicable, steam and/or compressed air supplies should also be disconnected before service is performed. 5.2.6 Inverter Drive Machines equipped with AC drives require special attention with regard to the operating environment. 1. An especially dusty or linty environment will require more frequent cleaning of the AC drive cooling fan filter and of the AC drive itself. 2.
5.3 Dimensional Clearances When installing the washer-extractor, it is important to allow adequate clearance on all sides of the machine. When multiple machines are installed, it is important to allow for the specified minimum clearances between machines. Figures 5.1 and 5.1 show recommended minimum clearances for the various freestanding models. Note: The dimensions are approximate and subject to normal manufacturing tolerances.
For a successful installation, a smooth level surface, so that the entire base of the machine is supported and rests on the mounting surface, is absolutely requried. Note: Do not support the machine on only four points. Note: Freestanding washer-extractors do not require anchoring bolts unless specified by state or local codes. However it is always recommended that the machines be anchored. Special care must be taken when machines are installed on an upper floor.
Figure 5.2: Typical Machinery Anchor Installation 4. Remove the spacers carefully, allowing the machine to settle into the wet grout. 5. Attached the mounting bolt washers and lock nuts to the anchor bolts after the grout has hardened. Tighten the lock nuts by even increments-one after the other-until all are tightened evenly and the machine is fastened securely to the floor. The nuts should be tightened in a diagonal fashion, which will help ensure equal tension at all anchor points. 6.
Figure 5.3: Typical Machinery Transportation Bracket Location conjunction with a sump pump should be used when gravity drainage is not possible, such as in below-ground-level installations. Before any deviation from specified installation procedures is attempted, the customer or installer should contact the manufacturer. Increasing the drain hose length, installing elbows, or causing bends will decrease drain flow rate and increase drain time, impairing machine performance.
Figure 5.4: Drain System Information This machine must be installed, adjusted, and serviced by a qualified electrical maintenance personnel familiar with the construction and operation of this type of machinery. They must also be familiar with the potential hazards involved. If this warning is not observed, personal injury or equipment damage resulting in voiding the warranty may result. transformer kit available from the manufacturer. Voltages above 250V and 490V require additional measures.
Never touch terminals or components of the AC drive unless power is disconnected and the ”‘CHARGE”’ indicator LED is off. The AC drive retains potential deadly voltage for some time after the power is disconnected. There are no userserviceable parts inside the AC drive. Tampering with the drive will void the warranty. Dangerous voltage are present in the electrical control boxes and at the motor terminals.
particles out of the solenoid valves. Hang the hoses in a large loop. Do not allow the hoses to kink. The water connections to the machine should be supplied by a hot and cold water line of least the sizes shown in table 5.4 on page 23. Refer to table 5.5 and 5.6 on page 23 for details on individual machine requirements. Table 5.
Never touch internal or external steam pipes, connections, or components. These surfaces can be extremely hot and will cause severe burns. The steam must be turned off and the pipe, connections, and components allowed to cool before the pipe can be touched.
