KitchenAid 15'' Automatic Ice Maker, Architect® Series II Installation Guide

15. Attach 

¹⁄₂" I.D. x 10 ft (3 m) drain tube to pump discharge tube. 

See “Parts Locations” illustration. 
NOTE: Do not connect outlet end of drain tube to a closed 
pipe system to keep drain water from backing up into the ice 
maker.

16. Connect ice maker to water supply and install ice maker as 

specified by the product installation instructions.

17. Check all connections for leaks.

18. Plug in ice maker or reconnect power.
19. Turn on ice maker.
20. Wait for rinsing cycle, approximately 5 minutes, to be sure the 

ice maker is operating properly.

Connect the ice maker drain to your drain in accordance with all 
state and local codes and ordinances. If the ice maker is provided 
with a gravity drain system, follow these guidelines when installing 
drain lines. This will help keep water from flowing back into the ice 
maker storage bin and potentially flowing onto the floor, causing 
water damage.

■

Drain lines must have a minimum of 

⁵⁄₈" (15.88 mm) I.D. (inside 

diameter).

■

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.

■

The ideal installation has a standpipe with a 1

¹⁄₂" (3.81 cm) to 

2" (5.08 cm) PVC drain reducer installed directly below the 
outlet of the drain tube as shown. You must maintain a 
1" (2.54 cm) air gap between the drain hose and the 
standpipe.

■

Do not connect the outlet end of the drain tube to a closed 
pipe system to keep drain water from backing up into the ice 
maker.

IMPORTANT: A drain pump is necessary when a floor drain is not 
available. A Drain Pump kit, Part Number 1901A, is available for 
purchase.

■

Connect the ice maker drain to your drain in accordance with 
the International Plumbing Code and any local codes and 
ordinances.

■

The drain pump discharge line must terminate at an open 
sited drain. 

■

Maximum rise 10 ft (3.1 m)

■

Maximum run 100 ft (30.5 m)

NOTES: 

■

If the drain hose becomes twisted and water cannot drain, 
your ice maker will not work.

■

It may be desirable to insulate the drain line thoroughly up to 
the drain inlet. An Insulation Sleeve kit, Part Number 
W10365792, is available for purchase.  

■

Do not connect the outlet end of the drain tube to a closed 
pipe system to keep drain water from backing up into the ice 
maker.
