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:
■
A reverse osmosis water filtration system is not recommended
for ice makers that have a drain pump installed.
■
For gravity drain systems 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 gal. (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.
Vacation or Extended Time Without Use
■
When you will not be using the ice maker for an extended
period of time, turn off the water and power supply to the ice
maker.
■
Check that the water supply lines are insulated against
freezing conditions. Ice formations in the supply lines can
increase water pressure and cause damage to your ice
maker or home. Damage from freezing is not covered by the
warranty.
Connect Water Supply
Read all directions before you begin.
IMPORTANT:
■
Connect to potable water supply only.
■
Plumbing shall be installed in accordance with the
International Plumbing Code and any local codes and
ordinances.
■
Use copper tubing or Whirlpool supply line, Part Number
8212547RP, 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.
Connecting the Water Line
1.
Turn off main water supply. Turn on nearest faucet long
enough to clear line of water.
2.
Using a 1/2" copper supply line with a quarter-turn shutoff
valve or the equivalent, connect the ice maker as shown.
NOTE:
To allow sufficient water flow to the ice maker a
minimum 1/2" diameter home supply line is recommended.
3.
Now you are ready to connect the copper tubing. Use 1/4"
(6.35 mm) O.D. soft copper tubing for the cold water supply.
■
Ensure that you have the proper length needed for the job.
Be sure both ends of the copper tubing are cut square.
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.
