USER GUIDE
Water Hookup
Water Hookup
TO PREVENT DAMAGE TO Y0UR ICE MACHINE
AND/OR VOID YOUR WARRANTY, FOLLOW ALL
WATER SUPPLY GUIDELINES AS LISTED BELOW.
PREPARE PLUMBING
The water valve uses a standard 1/4” (6.35 mm)
compression tting. U-Line recommends using accessory
water hook up kit – part # 80-54674-00. The kit includes
a 10’ (3 m) braided exible water supply line and a brass
hose tting.
Plumbing installation must observe all state
and local codes. All water and drain connections
MUST BE made by a licensed/qualied plumbing
contractor. Failure to follow recommendations
and instructions may result in damage and/or
harm.
Water Supply
When connecting the water supply, please note the
following:
• Water Mineral Content must meet the following:
◦TDS: less than 200 ppm (mg/l)
◦Hardness: Less than 200 mg/l (12 gpg)
• Water supply MUST NOT be from a water
softener.
• A TDS meter is included with your unit
• Water Treatment Options
◦TDS level of 200 ppm or higher and/or a
hardness of 12-19 gpg can be treated by U-Line’s in-line
water filter accessories available at u-line.com or your
local dealer:
 ULALINEFILTER — Standard
 ULALINEFILTERL — Large
 ULALINEFILTERHEAD — 3/8” NPT, initial
setup requires head & filter
• Use bypass level 6
Measure Water TDS
Every Nugget Ice Machine comes with a TDS meter similar
to the one below. The TDS meter measures the Total
Dissolved Solids level that exists in the water supply; this
is measured in ppm (parts per million).
The TDS meter does not test the toxicity of
the water and is not to be used to determine
potability. A TDS METER CANNOT DETECT THE
TOXINS THAT MAKE WATER UNSAFE TO DRINK.
1. Turn on sink faucet and let run for 30 seconds.
2. Fill a clean glass (2 inches of water is sucient).
3. Remove cap from meter.
4. Turn on meter and immerse meter into the water.
5. Leave meter immersed for 30 seconds.
6. Remove meter and check the readout for the TDS
level in ppm - to save the reading, press the hold
button.
7. Turn o meter, dry o, and replace cap.

• The water pressure should be between 20 and 120 psi
(138 and 827 kPa).
• The water line MUST have a shut-o valve in the
supply line.
• The water line should be looped into 2 coils. This
will allow the unit to be removed for cleaning and
servicing. Make certain that the tubing is not pinched
or damaged during installation.
Do not use any plastic water supply line. The line
is under pressure at all times. Plastic may crack
or rupture with age and cause damage to your
home.
Do not use tape or joint compound when
attaching a braided exible water supply line
that includes a rubber gasket. The gasket
provides an adequate seal – other materials
could cause blockage of the valve.
Failure to follow recommendations and
instructions may result in damage and/or harm,
ooding or void the product warranty.

USER GUIDE
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
backow 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.
