Drain

factory installed drain pump.

DRAIN CONNECTION
CAUTION
!
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 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, which may 
result in personal injury or property damage. 
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 fittings are free from 
leaks.
GRAVITY DRAIN
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.
CAUTION
!
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).
