Water Supply Requirements; Connect Water Supply - KitchenAid LKUIX335PPS Series Owner's Manual

13. Coil ice maker power cord into a 4" (10.2 cm) diameter coil.
Wrap electrical tape around the power cord in several places
to keep the cord in a coil. Locate coiled power cord between
the drain pump and side of enclosure and plug into the
receptacle of the drain pump. See "Parts Locations"
illustration in step 7.
14. Attach the drain pump power cord to ice maker unit base with
clamp and screw (removed in step 12) that was used to attach
ice maker power cord. See "Parts Locations" illustration in
step 7.
15. For standard model, place new rear panel (small one for 15ʺ
ice maker) against the back of the ice maker. Route the vent
tube and drain pump discharge tube through cutouts in the
rear panel.
16. Secure vent tube to back of ice maker using three clamps and
three #8–32 x 3/8ʺ screws, supplied. See "Vent Tube"
illustration in step 10.
17. Attach 1/2ʺ I.D. x 10 ft (3 m) drain tube to pump discharge
tube. See "Parts Locations" illustration in step 7.
NOTE: Do not connect outlet end of drain tube to a closed
pipe system to keep drain water from backing up into the ice
maker.
For standard models, skip to step 20.
18. Using a cable tie, fix the drain tube to rear panel.
19. Connect ice maker to water supply and install ice maker as
specified by the product installation instructions.
20. Check all connections for leaks.
WARNING
Electrical Shock Hazard
Plug into a grounded 3 prong outlet.
Do not remove ground prong.
Do not use an adapter.
Do not use an extension cord.
Failure to follow these instructions can result in death,
fire, or electrical shock.
21. Plug in ice maker or reconnect power.
22. Turn on ice maker.
23. Wait for rinsing cycle, approximately 5 minutes, to be sure the
ice maker is operating properly.

Water Supply Requirements

Check that the water supply lines are insulated against freezing
conditions. Ice formations in the supply lines can increase water
pressure and damage your ice maker or home. Damage from
frozen supply lines is not covered by the warranty.
A cold water supply with water pressure of between
30 and 120 psi (207 and 827 kPa) is required to operate the ice
maker. If you have questions about your water pressure, call a
licensed, qualified plumber.
Reverse Osmosis Water Supply
IMPORTANT:
� Do not use with water that is microbiologically unsafe or of
unknown quality without adequate disinfection before or after
the system. Systems certified for cyst reduction may be used
on disinfected waters that may contain filterable cysts.
� A reverse osmosis water filtration system is not recommended
for ice makers that have a drain pump installed.
� For gravity drain systems only.
� Connect to portable water only.
� The pressure of the water supply coming out of a reverse
osmosis system going to the water inlet valve of the ice maker
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 water pressure to the reverse osmosis
system needs to be a minimum of 40 to 60 psi (276 to 414 kPa).
NOTE: The reverse osmosis system must provide 1 gallon (3.8 L)
of water per hour to the ice maker for proper ice maker operation.
If a reverse osmosis system is desired, only a whole-house-
capacity reverse osmosis system, capable of maintaining the
steady water supply required by the ice maker, is recommended.
Faucet-capacity reverse osmosis systems are not able to maintain
the steady water supply required by the ice maker.
If the water pressure to the reverse osmosis system is less than
40 to 60 psi (276 to 414 kPa):
� Check to see whether the sediment filter in the reverse
osmosis system is blocked. Replace the filter if necessary.
� Allow the storage tank on the reverse osmosis system to refill
after heavy usage.
If you have questions about your water pressure, call a licensed,
qualified plumber.

Connect Water Supply

Read all directions before you begin.
IMPORTANT:
� Connect to potable water only.
� Do not use with water that is microbiologically unsafe or of
unknown quality without adequate disinfection before or after
the system. Systems certified for cyst reduction may be used
on disinfected waters that may contain filterable cysts.
� Plumbing shall be installed in accordance with the
International Plumbing Code and any local codes and
ordinances.
� Use copper tubing or supply line, and check for leaks.
� Install tubing only in areas where temperatures will remain
above freezing.
Tools Needed:
Gather the required tools and parts before starting installation.
� Flat-blade screwdriver
� 7/16" and 1/2" open-end wrenches or two adjustable wrenches
� 1/4" nut driver
NOTE: Do not use a piercing-type or 3/16" (4.76 mm) saddle
valve which reduces water flow and clogs more easily.
