- Page 8 Before Using this unit Requirements for Installation 8. Connection of power cord Always ensure that breaker on power unit side is "Off" before connecting power cord. Power plug of this unit uses 3-core cord including grounding wire, and the plug is grounded type. If your plug socket is not compatible (2P), use a ground adapter attached in nonstandard.
- Page 9 Before Using this unit Requirements for Installation 12. Connection on body side 1. Remove the rubber cap from the water supply port plug Body side ⑧. 2. Insert the socket ⑨ securely to the plug ⑧ on body ⑧ side with the sleeve slid in the arrow direction. The sleeve returns to the original position when released, and then connection is completed.
- Page 10 Before Using this unit Requirements for Installation CAUTION! 14. When the sink equipment is remote from water tap, use "Water Supply Port Unit" (optional accessory) "Water Supply Port Unit" is designed to loosen the connection to the tap harder than the set of standard water supply hoses when water pressure fluctuates.
- Page 11 Drain trap makes temperature fall by accumulating cooled drain water temporarily. Further, it mixes city water and cooled-down drain water, makes mixed water temperature fall, then lets drain to sink equipment. Contact your dealer or Yamato Scientific sales office for detail of drain trap.

Page 17: Principle Of Operation
Description and Function of Each Part Principle of Operation 1. Boiler Water Supply and Distilling Operation Turn ON the earth leakage breaker, and press the power switch. Then, the raw water supply solenoid valve (4) and the boiler water supply solenoid valve (15) open at the same time to supply water to the boiler (11). When the float switch 1 (8) in the float cylinder (7) detects water level, the heater (12) is energized to start distillation. - Page 18 Description and Function of Each Part Principle of Operation 3. Sampling of Distilled Water The distilled water condensed in the condenser (13) is stored in the distilled water tank (21) after discharging the initial boiled water via the initial boiled water discharge solenoid valve (16) for about 10 min. after power switch is turned ON.
