Page 7: Before Using This Unit
Before Using this unit Requirements for Installation WARNING! 1. Always ground this unit • Connect the power plug to a receptacle with grounding connectors. • Do not forget to ground this unit, to protect you and the unit from electrical shock in case of power surge. - Page 8 • Never disassemble this unit. • This unit has high voltage inside in some portion, which may cause electric shock. Contact dealers or Yamato Scientific Co., Ltd. sales office for adjusting or repairing inside. • In routine maintenance and inspection, follow the procedure described in the instruction manual.
- Page 9 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 WG250 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 10 Before Using this unit Requirements for Installation 11. Observe the specified pressure range of raw water from waterworks • Apply the range of city water pressure between 0.5 X 100kPa and 5 X 100kPa (0.5 - 5kgf/cm2) including nighttime. • Range of raw water pressure is the same when "Water Supply Port Unit" (optional accessory) is used.
- Page 11 Before Using this unit Requirements for Installation 16. Connect the drain hose securely • If the drain hose is not connected securely, it may be disconnected, leaking water in the unit, or leading to trouble of system. 1. Pick up the drain hose (with elbow) and the hose clamp from the main unit accessories. 2.
- Page 12 • 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 13 Before Using this unit Requirements for Installation 20. Install the ion exchange resin cartridge (CPC-S) securely • Install the ion exchange resin cartridge (CPC-S) following the procedure shown below. • Connect securely because insecure connection may cause water leakage. 1. Make sure that the earth leakage breaker of this unit is "Off" and that the tap is tightened. 2.
- Page 14 Before Using this unit Requirements for Installation 21. Secure the pre-treatment cartridge securely • Connect the hose in the body securely following the procedure shown below. • Insecure connection may cause disconnection of connection hose, resulting in accident by water leakage. 1.
- Page 15 2. Before Using this unit Requirements for Installation WARNING! 22. Install the membrane filter firmly. • Install the membrane filter as follows: • Unless firm connection is made, water may leak from the threaded portion and may be mixed into and contaminate the sampled pure water.
