The drain and inlet water tubes must be
plumbed before connecting to the ice maker.
Refer to the illustrations below. All horizontal
runs of drain lines must have a
1
/

" (6) per 12"
(305) fall. An air gap will likely be required
between the ice maker drain tube and the
drain/waste water receptacle. A stand pipe
with a trap below it can be used for the
drain/waste water receptacle.
IMPORTANT NOTE: Poor drainage will cause
a high rate of ice melting in the ice storage bin.
1)
Place the ice maker in front of the installa-
tion opening. Adjust leveling legs to the
approximate height.
2)
Remove the door (with hinges), control
knob, control panel, access panel and lower
face plate.
3)
Route the water inlet line (
1
/
4
" OD copper
tube) from the wall through the ice maker
to the front.
4)
Route the drain line from the wall position
through the ice maker. If you have a hori-
zontal run longer than 5' (1.5 m), the drain
should be vented at the back of the unit.
5)
If the electrical outlet for the ice maker is
behind the unit, plug in the unit.
6)
Position the unit in the installation opening.
7)
Cut the water inlet line to the required
length.
8)
Flush the water line. Place the flare nut on
the water line and flare the end of the
copper tube.
9)
Attach the flare nut to the male flare on the
inlet water valve.
10)
Cut the drain tube to the required length.
11)
Connect the
5

" drain tube to the storage
bin drain fitting at the bottom of the bin.
Secure with hose clamps. Be sure that the
drain tube is pushed up well past the barbs
on the drain fitting. If needed to ease instal-
lation, soak the drain hose in hot water just
before connecting to the fitting.
12)
Turn on the water supply and check for
leaks.
13)
Replace the door (with hinges), control
knob, control panel, access panel and lower
face plate. Level the unit as needed.
