  • Page 12: Installation

    Installation NOTE: Install the W105ES using the front and rear pairs of bolt holes. The middle pair is used when a W105ES is being installed in replacement of a W73, W74 or W75 washer. In that case the rear bolt holes are not necessary but may also be used.
  • Page 13 Installation Electrical Connections: Although the machines are fitted with a thermal overload in the motor windings, a separate three- Fig. phase common-trip circuit breaker must be installed for all three-phase machines. For proper circuit breaker protection, check the data plate at the rear of the machine. Also consult local electrical code for special requirements.
  • Page 14 Installation Water Connections: NOTE All plumbing must conform to national and local plumbing codes. Incoming water lines do not require non-return or Fig. back flow prevention valves, as the machine is already fitted with an approved siphon breaker. However, all incoming lines must be fitted with shut-off valves.
