Information on the Different Types of Drain Pumps
There are two different types of of drain systems that can be used with the Whirlpool freestanding ice maker. Below outlines information on both systems.
Gravity Drain Systems
Gravity drain systems are used when a near by floor drain is available. Drain lines must have a 1" drop per 48" (2.54 cm drop per 122 cm) of run or ¹⁄4" drop per 12" (6.35 mm per 30.48 cm) of run and must not have low points where water can settle. The floor drains must be large enough to accommodate drainage from all drains
Drain Pump Systems
A drain pump is designed to pump water to a maximum height of 10 ft (3 m) and is necessary when a floor drain is not available. Use only Whirlpool approved drain pump kit Part Number 1901A. Some models come with the drain pump already equipped, if your ice maker didn't come with a drain pump, and it is needed, it can be purchased as an accessory.
