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 during the summer
months, turn off the water and power supply to the ice maker.
Make sure the water supply lines are protected 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:
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.
