SITE PREPARATION
Electrical
Installation must comply with all applicable electrical codes.
The electrical supply should be located within the shaded
area shown in the illustration below. A separate circuit, servicing only this appliance is required. A ground fault circuit
interrupter (GFCI) is not recommended and may cause interruption of operation.
ELECTRICAL REQUIREMENTS
Electrical Supply 115 VAC, 60 Hz
Service 15 amp
Receptacle 3-prong grounding-type
CAUTION
The outlet must be checked by a qualied electrician to
be sure that it is wired with the correct polarity. Verify
that the outlet is properly grounded.
WARNING
Do not use an extension cord, two-prong adapter or
remove the power cord ground prong.
Plumbing
Installation must comply with all applicable plumbing codes.
The water supply line should be located within the shaded
area shown in the illustration below. The water supply line
should be connected to the house supply with an easily
accessible shut-off valve. Do not use self-piercing valves.
The water supply line must not interfere with installation of
the anti-tip bracket.
A reverse osmosis system can be used provided there is
constant water pressure of 35–120 psi
to the unit at all times. In this application, the water ltration
system must be bypassed by removing the lter. A copper
line is not recommended for this application.

SITE PREPARATION
Preparation
Uncrate the unit and inspect for damage. Remove the wood
base and discard shipping bolts and brackets. Remove and
recycle packing materials. Do not discard the kickplate, antitip bracket and hardware.
Completely retract the front leveling legs to allow the unit to
be moved into position. The front and rear leveling legs can
be adjusted from the front once the unit is in position.
Remove the drain pan from the base of the unit to avoid
damage, and allow for proper appliance dolly placement.
The grille assembly should be removed prior to moving the
unit. To remove, pull out on the bottom edge of the grille and
rotate upward. Cut cable ties that attach the network cable
to the grille, then disconnect the network cable. Remove
three grille bolts from the grille, then pull grille forward to

WARNING
To prevent the unit from tipping forward, the anti-tip
bracket must be installed.
Use the centerline locating holes to position the anti-tip
bracket in the center of the opening. The bracket must be
positioned 24"
back of the bracket. This depth will increase to 26"
a ush installation. Failure to properly position the anti-tip
bracket will prevent proper engagement.
Use all anti-tip bracket hardware as instructed for wood or
concrete oors.
IMPORTANT NOTE: For wood or concrete oor applications,
if the #12 screws do not hit a wall stud or wall plate, use the
#8 screws and #12 washers with the wall anchors.
IMPORTANT NOTE: In some installations the subooring or
nished oor may necessitate angling the screws used to
fasten the anti-tip bracket to the back wall.

minimum embedment. Clean the hole or drill additional
depth to accommodate drill nes.
2 Assemble the washer and nut ush with the end of
anchor to protect threads. Drive the anchor through the
material to be fastened until the washer is ush with the
surface material.
3 Expand the anchor by tightening the nut 3–5 turns past
hand-tight position or to 25 foot-pounds of torque.
WARNING
Verify there are no electrical wires or plumbing in the
area which the screws could penetrate.
CAUTION
Always wear safety glasses and use other necessary protective devices or apparel when installing or
working with anchors.
Anchors are not recommended for use in lightweight

CAUTION
Before moving the unit into position, secure doors and
drawers closed and protect any nished ooring.
Use an appliance dolly to move the unit near the opening.
If the unit has been on its back or side, it must stand upright
for a minimum of 24 hours before connecting power.
Plug the power cord into the grounded outlet and roll the
unit into position. Verify the anti-tip bracket is properly
engaged.
Water Line
Approximately 3' (.9 m) of 1/4" plastic tubing is connected to
the unit with a preassembled
under the unit. The water line tting connection kit, provided
with the unit, contains a
connection to the household water line.
Purge the water line prior to nal connection to the unit. This
will remove any debris that may be present in the tubing
from installing the new water line.

LEVELING
Once the unit is in position, turn the front leveling legs
clockwise to adjust the height. The rear height adjustment
can be made from the front of the roller base. Using a
3
socket, turn the
/8" hex bolt clockwise to raise the unit or
counterclockwise to lower. Use the lowest torque setting
when using a power drill. Do not turn the rear leveling legs
by hand. Refer to the illustration below.
When the unit is properly leveled, door and drawer adjustments are less likely to be necessary.
IMPORTANT NOTE: Level the unit to the oor, not sur-
rounding cabinetry. This could affect the operation of the
unit, such as door closing.
WARNING
To reduce the possibility of the unit tipping forward, the
front leveling legs must be in contact with the oor.

Place the sleeve and nut on the water line and fasten
to the connection at the end of the tubing. Do not over
tighten. Check all water line ttings for leaks. Verify the
drain pan can be installed and removed without water line
interference.
IMPORTANT NOTE: If a reverse osmosis system used, it is
recommended that the water ltration system be bypassed
by removing the lter.
IMPORTANT NOTE: Water lines can not be exposed to
freezing temperatures.
