•
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. Always make sure that the earth leakage breaker of the unit is "OFF".
3. Remove the rubber stopper from the outlet of the drain port hose on the main unit.
4. Push the hose clamp into the elbow of the drain hose, and next, put the elbow into the drain
outlet hose of the main unit, then tighten the hose clamp securely.
5. Pull the hose out from the drain hose-end outlet at right/left or backside of the main unit.
For WG1000 unit, be sure to set the hose in the hose holder at the backside plate.

17. Use care in routing of drain hose
•
Do avoid making bend or projection of drain hose.
•
In case that the drain hose is bent and the drain cannot be performed, back-flow or breakage
of the cooling hose might occur.
•
Place the drain hose lower than the drain port of this unit. Further, avoid piping which allows
paddle in the hose or at the hose outlet, because it is a resistance against drain.
•
Place the end of drain hose where drain is allowed. When distilled water is being prepared,
cooling water is drained approx. 2 liters/min (approx. 2.6 liters/min in WG1000). Also drain
further increases when boiler water is drained, and sufficient drain equipment is required.
