CAUTION
Plumbing installation must observe all state and local codes.
All water and drain connections MUST BE made by a
licensed/qualified plumbing contractor. Failure to follow
recommendations and instructions may result in damage
and/or harm.
DRAIN CONNECTION
IMPORTANT
IMPORTANT
Drain can NOT be located directly below unit. Unit has a
solid base that will not allow unit to drain below itself.
The unit can be installed using a gravity drain, a factory-installed drain
pump (U-Line P60) or a locally installed drain pump. Drain lines must
have a 5/8" inside diameter. The floor drain must be large enough to
accommodate drainage from all attached drains.
Follow these guidelines when installing drain lines to prevent water
from flowing back into the ice maker storage bin and/or potentially
flowing onto the floor, causing water damage:
GRAVITY DRAIN
A Gravity Drain may be used if:
• Drain line has at least a 1" drop per 48" of run
(1/4" per foot).
• Drain line does not create traps or created traps are vented
(Figure 62).
Figure 62
See Figure 63 for a typical gravity drain installation.
Figure 63
If using a gravity drain:
1. Attach the 5/8" ID drain connection on the back of the unit to a
5/8" OD rigid tube, using a worm clamp.
2. Attach the other end of the rigid tube to your 5/8" ID drain line
with a worm clamp.
3. Insulate the drain line, if necessary, to prevent condensation.
FACTORY-INSTALLED DRAIN PUMP
If your drain line will run up to a stand pipe, disposal assembly or
spigot assembly or does not otherwise meet the requirements for a
gravity drain, you may have ordered the CLR2160 with a U-Line P60
drain pump. See Figure 64, Figure 65 and Figure 66 for typical
installations requiring a drain pump. If you need to install a P60 drain
pump into your unit, see Locally-Installed Drain Pump.
