Installation Installation 7 2 Machine foundation Fig. 2 Fig. 3 Fig. 4 The machines are designed to be bolted in position to a concrete floor or specially prepared concrete foundation. A template showing the size of the foundation and positioning of the foundation bolts is delivered with each machine. For installation on an existing concrete floor, the floor must be at least 8" thick and of good quality.
Installation 8 Mechanical installation Fig. 5 5 • Place wide steel shims on the concrete foundation over the bolts. • Lift the machine and lower it in position. Never use the door or the door handle to lift or lower the machine. Fig. 6 Fig. 7 • Check that the machine is level front-to-rear and side-to-side and standing firmly on the four (W75, W105) or six (W125 W185) supporting points. Spacing washers must be mounted if one or more of these points is not resting against the floor/foundation.
Installation Electrical installation Fig. 8 9 8 Although the machines are fitted with a thermal overload in the motor windings a separate threephase common-trip circuit breaker must be installed for all three-phase machines. For proper overcurrent protection, check the data plate at the rear of the machine. Also consult local electrical code for special requirements. Fig. 9 Connect L1, L2, L3 and ground wires according to the markings of the terminal block.
Installation 10 Water connection 11 NOTE All plumbing must conform to national and local plumbing codes. Fig. 11 Fig. 12 Fig. 13 Incoming water lines do not require non-return or back-suction valves, as the machine is already fitted with a siphon breaker. However, all incoming lines must be fitted with shut-off valves. • Water inlets are labelled for hot and cold water connection. 1832 • Flush the water system thoroughly and check that the filter at the machine inlet is fitted correctly.
Installation 11 How to size water supply piping for Wascomat coin laundries 1. Calculate the total number of gallons of water that would be needed if all present (and future) washers were to fill at the same time. Assume the W75 (18-lb.) uses 7 gallons per fill; W105 (25-lb.) uses 10 gallons per fill; W125 (35-lb.) uses 14 gallons per fill‚ W185 (80-lb.) uses 20 gallons per fill; and W244 (75-lb.) uses 30 gallons per fill. If water pipe runs of 70 feet or longer are required, multiply by 1.
Installation 12 Drain connection Fig. 14 14 Connect a 3" (75 mm) flexible hose to the drain outlet of the machine. The drain hose must not have sharp bends and must slope from the machine to assure proper drainage. The outlet must open freely to the main drains. Do not reduce the size of the drain connection from the machine to the waste line. Start-up and safety checklist Before initial start-up of a Wascomat washerextractor, the following safety checks must be performed: Fig. 15 Fig.
Installation Before the machine is operated, the door safety interlock must be checked for proper operation as follows: Fig. 17 Fig. 18 13 17 • When washer loading door is open, the machine must not start.
