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/qualied plumbing 
contractor. Failure to follow recommendations 
and instructions may result in damage and/or 
harm.

• 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.
Use new hose set. Do not reuse old hose set.
Turn off water supply and disconnect electrical 
supply to unit prior to installation.
Use caution when handling back panel. The edges 
could be sharp.
