Always keep your working area dry.
NOTICE
Electrical installation must observe all state and local codes. This unit requires connection to a grounded (three-prong), polarized receptacle that has been placed by a qualified electrician.
The unit requires a grounded and polarized 115 VAC, 60 Hz, 15A power supply (normal household current). An individual, properly grounded branch circuit or circuit breaker is recommended. A GFCI (ground fault circuit interrupter) is usually not required for fixed location appliances and is not recommended for your unit because it could be prone to nuisance tripping. However, be sure to consult your local codes.
Water Hookup
PREPARE PLUMBING
The water valve uses a standard 1/4” (6.35 mm) compression fitting. U-Line recommends using accessory water hook up kit – part # 80-54674-00. The kit includes a 10’ (3 m) braided flexible water supply line and a brass hose fitting.
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.
Water Supply Connection
When connecting the water supply, please note the following:
- Before installing the unit and connecting to the cold water supply, review the local plumbing
- The water pressure should be between 20 and 120 psi (138 and 827 kPa).
- Water has less than 400 mg/L (ppm) total dissolved solids and hardness level below 200 mg/L (ppm) — e., below 12 grains per gallon. Check by using TDS meter or consulting with local water company.
- TDS and/or water hardness above these limits should be treated with a reverse osmosis system or other filtration
- Softened water is not recommended as it may result in softer ice than

Drain
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
DRAIN CONNECTION
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.
- Cut the pre-installed drain tube to
- Connect to your local plumbing per the local
- If necessary, insulate drain line to prevent
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).
FACTORY INSTALLED DRAIN PUMP
If your drain line will run up to a stand pipe, disposal or
spigot assembly, or does not otherwise meet the requirements for a gravity drain, you may have ordered a pre-installed U-Line P60 drain pump.
If you need to install a P60 drain pump into your unit, see DRAIN PUMP section in the User Manual.
See below for typical installations requiring a drain pump.
The maximum lift for the P60 drain pump is
10 feet. This must be done as close to the rear of the unit as possible.
1/2″ (13 mm) clearance is recommended from wall on hinge side to allow the door to open 90°. Allow for additional space for any knobs or pulls installed on the integrated panel/frame.
Stainless Steel models that are installed adjacent to a wall require 2-1/4″ (57 mm) door clearance on hinge side to allow for door handle.
Units have a zero clearance when installed adjacent to cabinets

First Use
Initial startup requires no adjustments. See CONTROL OPERATION section for more details.
U-Line recommends discarding the ice produced during the first two to three hours of operation to avoid possible dirt or scale that may dislodge from the water line.
When plugged in, the unit will begin operating under the factory default settings. If the unit was turned off during installation, simply press and the unit will immediately switch on. To turn the unit off, press and release.
Ice
The Nugget Ice Machine produces cylindrical bits of compressed ice approximately 3/4” x 1/2”.
Ice is produced until the machine senses the bin is full. As ice slowly melts in the bin, the level of ice drops and ice production resumes. This ensures a constant supply of fresh ice is always available.
The factory default ice setting is 0, which produces a firm and compact ice nugget. U-Line’s exclusive
U-Choose™ ice adjustability feature allows you five levels of adjustment from 0 to -5. At -5 the ice is soft and chewable.
To adjust the ice density:
- Hold for 5 seconds – display will flash current ice setting
