Drain hose should be short and drooping gradient should at less 1/100 to prevent the formation of air bubble.
If drain hose cannot has enough drooping gradient, drain raising pipe should be added.
To prevent bent of the drain hose, the distance between hoisting stand should is 1 to 1.5m. (As shown in Figure
1-3-8)
