(Figure 3-12: Drain Pipe)
Gravity drainage is completely driven by the drain pipe height and slope. Therefore, please
follow and maintain the following principles.
(1) Please maintain a direct descend of the drainage pipes to the raised floor, else
condensed water will gather on the pipelines.
(2) The water drainage slope of the drain pipes beneath the raised floor must be greater
than 1/100 to ensure normal flow rate of the condensed water.
(3) To prevent air or condensed water in drain pipes from returning to inside the equipment
during indoor fan operation, the U-trap must have a minimum depth of 8 inches.
Therefore, please first check the space of the raised floor.
