Drain
If your U-Line unit did not come with a factory 
installed drain pump you must use a gravity 
style drain connection. For assistance in 
determining if your unit has a pump please 
contact U-Line. The oor drain must be large 
enough to accommodate drainage from all 
attached drains. Follow these guidelines when 
installing drain lines to prevent water from 
owing back into the ice maker storage bin and/
or potentially owing onto the oor, which may 
result in personal injury or property damage
Failure to connect water supply or drain line 
connections properly can result in personal injury 
and property damage. Gravity drain connections 
must be routed downward from the rest of the 
unit at the rate of 1/4” per foot (1 cm per 50 cm). 
Drain can NOT be located directly below the 
unit. Unit has a solid base that will not allow the 
unit to drain below itself.
There is a possibility that hose connections may 
have loosened during shipment. 
Verify all connections and ttings are free from 
leaks.
This equipment is to be installed with adequate 
backow protection to comply with applicable 
federal, state and local codes
Model numbers including “CL” or “NB” do not include a 
factory installed drain pump.
Model numbers including “CP” or “NP” include a factory 
installed drain pump.
A gravity drain may be used if:
Drain line has at least a 1” drop per 48” (approximately 
2 cm drop per 100 cm) of run.
Drain line does not create traps and is vented per local 
code.
1.  Cut the pre-installed drain tube to length.
2.  Connect to your local plumbing per the local code.
3.  If necessary, insulate drain line to prevent 
condensation.
