Electrical Requirements
Water Pressure
A cold water supply with water pressure between 30 and 120
psi (207 and 827 kPa) is required to operate the water
dispenser and icemaker. If you have any questions about your
water pressure, call a licensed, qualified plumber.
Reverse Osmosis Water Filter System
Water Supply Requirements
NOTE: If the water shutoff valve is in the back wall behind the
refrigerator, it must be at an angle so that the tube is not kinked
when the refrigerator is pushed into its final location.
All installations must meet local plumbing code requirements.
The water shutoff should be located in the base cabinet on
either side of the refrigerator or some other easily accessible
area. The right-hand side is recommended. The access hole
through the cabinet must be within ½” (12.7 cm) of the rear
wall.
IMPORTANT: The pressure of the water supply coming out of a reverse
osmosis system going to the water inlet valve of the refrigerator needs to
be between 30 and 120 psi (207 and 827 kPa).
If a reverse osmosis water filtration system is connected to your cold water
supply, the pressure to the reverse osmosis system needs to be a minimum
of 40 to 60 psi (276 to 414 kPa).
If the water pressure to the RO system is less than 40 to 60 psi
(276 to 414 kPa):
Check to see whether the sediment filter in the RO system is
blocked. Replace the filter if necessary.
Allow the storage tank on the RO system to refill after heavy usage.
If your refrigerator has a water filter cartridge, it may further reduce
the water pressure when used in conjunction with an RO system.
Remove the cartridge filter.
If you have any questions about your water pressure, contact a licensed,
qualified plumber.

Stainless Steel Side Panels
Custom side panels will be needed when not enough space is available to
have cabinets on both sides of the refrigerator or when the refrigerator is
placed at the end of a cabinet run. You may choose an Inset, Flush, or
Recessed panel installation.
Refrigerator and Side Trim Dimensions
The width and height of a side panel are determined by the type of installation
you are planning.
NOTES:
The dimensions shown are actual product dim’s and may not
reflect the needed panel installation dim’s.
The side panel should be a min. of ½” (1.27 cm) thick to avoid
warping.
If the opening depth is 25” (63.5 cm) or more, you may want to
install a support board on the rear.

the shipping base to the refrigerator bottom.
NOTE: Do not remove tape and door bracing until the
refrigerator is in its final location.
If necessary, reduce the tipping radius. See “Tipping
Radius” for ceiling height requirements or “Reduce Tipping
Radius” for step by step instructions. If you do not need to
reduce the tipping radius, proceed to “Move the
Refrigerator into House.”

Reduce the Tipping Radius (If necessary)
Install Anti-Tip Boards
Before bring the refrigerator into the home, be sure there is adequate
ceiling height to stand the refrigerator upright. See “Tipping Radius” page
15, for more information.
If you do not have adequate ceiling height to stand the refrigerator
upright, the tipping radius can be reduced by removing the top grille and
side trims
(See the following chart)
MODEL
REDUCED TIPPING RADIUS
42”
88 ½” (223.5 cm)
48”
89 ¼” (226.7 cm)
1) Grasp both ends of the top grille
2) Push the top grille straight up; then pull straight out. Lay the grille
on a soft surface.
3) Remove the six screws attaching each cabinet side trim to the
refrigerator and remove the side trims.
IMPORTANT:
To avoid tipping during use, the solid soffit must be within
1” (2.5 cm) maximum above the refrigerator. If the solid soffit is higher
than
1” (2.5 cm) or one is not available, then the refrigerator must be braced.
It is recommended that the board(s) be installed before the refrigerator
is installed.
Board(s) must be long enough to fully cover the width of the compressor
cover.
Locate the board(s) so the bottom surface(s) of the board(s) is (are)
84” (213 cm) from the floor.
During installation, raise the refrigerator up so there is ¼” (6.35 mm)
maximum between the top of the refrigerator and the bottom of the anti-
tip board(s). Do not crush the compressor cover when raising the rear
leveling legs.
To install the anti-tip boards
1) Mark the stud locations on the rear wall 80” to 90” (203 cm to 229 cm)
above the floor.
2) Securely attach one or two 2” x 4” x 32” (5 cm x 10 cm x 81 cm)
Boards to wall studs behind refrigerator. Use six #8 x 3” (7.6 cm)
(or longer) wood screws. The wood screws must be screwed into the
studs at least 1 ½” (3.8 cm). The board(s) must overlap the compressor
cover.

Style # 1 –Shut-Off Valve Connection
Connect the Water Supply
A. Center board ¼” (6.35 cm) max. above refrigerator.
B. 2” x 4” x 32” (5 cm x 10 cm x 81 cm) boards (2).
C. Attach to studs with #8 x3” (7.6 cm) screws (6).
D. Compressor cover.
Read all instructions before you begin.
IMPORTANT: If you turn the refrigerator on before the
water line is connected, turn the icemaker OFF.
Parts Needed:
Minimum 7 ft (2.13 m) flexible,
(Local Code Approved) water supply line
NOTE: If your water line connection does not look like “Style #
1”, See Style # 2, “Copper Line Connection” instructions next
page.
1) Unplug refrigerator or disconnect power supply.
IMPORTANT: Before attaching the tubing to shutoff valve, flush
the main water supply line to remove particles and air in the
water line. Allow enough flow so that water becomes clear.
Flushing the water line may help avoid filters and/or water
valves from becoming clogged.
1) Connect the flexible, (Local Code Approved) water
supply line to the water shutoff valve by threading the
provided nut onto the shutoff valve as shown.
2) Place the end of the tubing into a bucket, and turn the
shutoff valve to ON.
3) Check for leaks. Tighten any nuts or connections
(including connections at the valve) that leak.

Style # 2
Style # 2 –Copper Line Connection
NOTE: If there is a water supply line that meets the specifications in
“Water Supply Requirements,” proceed to “Connecting to
Refrigerator.” If not, use the following instructions to connect to the
household cold water supply.
1) Unplug the refrigerator or disconnect the water supply.
2) Turn OFF main water supply. Turn ON nearest faucet long
enough to clear line of water.
3) Locate a ½” to 1 ¼” (1.3 cm to 3.2 cm) vertical cold water
pipe near the refrigerator.
IMPORTANT:
Make sure it is a COLD water pipe.
Horizontal pipe will work, but drill on the top side of the pipe,
not on the bottom. This will help keep water away from the drill
and keep normal sediment from collecting in the valve.
4) Determine the length of copper tubing you need. Measure
from the connection on the refrigerator to the water pipe.
Add 7 ft (2.1 m) to allow for cleaning. Use ¼” (6.35 mm)
O.D. (outer diameter) copper tubing. Be sure both ends of
copper tubing are cut square.
5) Using cordless drill, drill a ¼” (6.35 mm) hole in the cold
water pipe you have selected.
6) Fasten the shutoff valve to the cold water pipe with the pipe
clamp (B)
Be sure the outlet end is solidly in the ¼” (6.35 mm) drilled hole
in the water pipe and that the washer is under the pipe clamp
(B). Tighten the pipe clamp (B) screws slo0wly and evenly so
the washer makes a watertight seal. DO NOT OVERTIGHTEN.
MPORTANT: Before attaching the tubing to shut valve, flush the main
water supply line to remove particles and air in the water line. Allow
enough flow so that the water becomes clear. Flushing the water line
may help avoid filters and/or water valves from becoming clogged.
Slip the compression sleeve and compression nut on the copper
tubing as shown. Insert the end of the tubing into the outlet end
squarely as far as it will go. Screw compression nut onto outlet end
with adjustable wrench. Do not over tighten the clamp or the sleeve,
the tubing may
7) Turn OFF the shutoff valve on the water pipe. Coil the copper
tubing
8) Connect the flexible (Local Code Approved) water supply line to
thewater shutoff valve by threading the provided nut onto the shutoff
valve.
9) Place the end of the tubing into a bucket, turn shutoff valve to ON.
10) Check for leaks around the saddle valve. Tighten any nuts or
connections(including connections at the valve) that leak.
