Chapter 2 Introduction The HE line is the professional fixed mount washer-extractor series of machines from B&C Tech- nologies. It is an open pocket washer-extractor with a large door opening for easy and quick loading and unloading. It has been developed for the on premise market, and is suitable for com- mercial laundries, hotel and other places where laundry might be processed. -
Page 11: Replacement Parts
2.2 Replacement Parts In the event that literature or replacement parts are required, contact the local distributor of the equipment, or contact B&C Technologies at the above phone numbers/internet addresses. 2.3 Theory of Operation The HE models use a single-speed motor to drive the cylinder via V-belts in all speeds. The cylin- der is supported by two spherical roller bearings located in a bearing housing made of cast iron. - Page 12 Holes are provided at the rear of the machine for connection to an external, central liquid supply unit. Electrical connections are provided for the liquid supply unit on a terminal strip inside the rear control module. Refer to page 32 for connection details.

Page 15: Installation
Chapter 4 Installation 4.1 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. -
Page 16: Operator Safety
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. -
Page 17: Safe Operation Environment
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 ma- chine with volatile or flammable fluids such as acetone, lacquer thinners, enamel reducers, carbon tetrachloride, gasoline, benzene, naphtha, etc. -
Page 18: Machine Location
Replace all panels that are removed to perform service and maintenance pro- cedures. Do not operate the machine with missing guards or with broken or missing parts. Do not bypass any safety devices. 4.2.4 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. -
Page 19: Inverter Drive
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. 4.2.6 Inverter Drive Machines equipped with AC drives require special attention with regard to the operating envi- ronment. -
Page 20: Dimensional Clearances
4.3 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. The following table shows recommended minimum clearances for the various freestanding models. -
Page 21: Machine Foundation
Ensure that the machine is installed on a level floor of sufficient strength and that the recommended clearances for inspection and maintenance are provided. Never allow the inspection and maintenance space to be blocked. 4.4 Machine Foundation A proper foundation is an absolute necessity when installing a fixed mount washer extractor. Do not neglect details when doing foundation work. -
Page 22: Machine Foundation Construction
Figure 4.3: Foundation Bolt Location Figure 4.4: Typical Grouting Pattern 4.4.1 Machine Foundation Construction Place the machine adjacent to the foundation. Do not attempt to move it by pushing on the sides. - Page 23 Figure 4.5: Machine Foundation Detail 1. Remove the wood skid by unscrewing the carriage bolts holding it to the bottom frame of the machine. 2. Carefully place the machine over the anchor bolts. Raise and level it 1/2 inch above the floor on four points, using spacers that can be removed.

Page 31: Water Connection
Dangerous voltage are present in the electrical control boxes and at the motor terminals. Only qualified personnel familiar with electrical test procedures, test equipment, and safety precautions should attempt adjustments and troubleshoot- ing. Disconnect power from the machine before removing the control box cover, and before attempting any service procedures. -
Page 32: Steam Connection
Figure 4.14: Water Connection Detail 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. -
Page 33: Chemical Connection
Figure 4.15: Steam Service Connection Detail Wear Eye and hand protection when handling chemicals. Always avoid direct contact with raw chemicals. Read the manufacturers directions for accidental contact before handling chemicals. Ensure that an eye-rinse facility and an emer- gency shower are within easy reach. Check at regular intervals for chemical leaks. -

3. Check all painted surfaces for bare metal (matching paint is available from the manufacturer.) (a) If bare metal is showing, paint with primer or solvent-based paint. (b) If rust appears, remove it with sand paper or chemical means. Then paint with primer or solvent-based paint. - Page 47 1. Ordinary deposits if dirt and grease can be removed with detergent and water. The metal should be thoroughly rinsed and dried after washing. Periodic cleaning will help to maintain the bright surface appearance and prevent corrosion. 2. Contact with dissimilar metal should be avoided whenever possible. This will help prevent galvanic corrosion when salty or acidic solutions are present.
