Installation Requirements
Properly tighten all fittings to ensure a leak-free assembly.
n
Filter housing is intended for use on cold water line.
n
Install in a location that is not susceptible to freezing
n
temperatures as damage to the housing could occur.
Install away from direct sunlight as prolonged exposure to
n
light can weaken plastic components.
Allow a minimum of 2" (5.1 cm) clear space below unit to
n
facilitate filter change.
Some local codes may require the use of a licensed
n
plumber or certified installer when disrupting a potable
water line. Determine and follow any and all local codes and
requirements.
Pipe and filter need to be properly supported with pipe
n
hangers.
For metal water piping systems a grounding connection is
n
required (Whirlpool Grounding Kit WHKF-GRND).

Installation Instructions
For Use With Cold Water Only
1. Shut off main water supply. Drain water from water lines.
2. Remove opaque housing from filter head and set aside.
3. Wrap Teflon
tape (2 1/2 wraps) around the 3/4" MNPT
®
x 3/4" fitting for copper pipe in a clockwise direction
(see Figure 1) and firmly assemble into filter head.
Do not use pipe sealant (dope), as solvents in some
types of pipe dope may cause damage to plastic fittings.
Do not overtighten, overtightening can cause damage to
filter head.

4. Calculate proper spacing of components (approximately
3/4" of existing pipe inserts into each fitting) (see Figure 2).

5. Install Whirlpool Grounding Kit WHKF-GRND, sold
separately, in metal water piping systems (see Figure 3).
IMPORTANT: Metal water piping systems are required to
be connected to the electrical ground. To maintain the
ground connection, obtain and install kit WHKF-GRND by
contacting the store where the filter head was purchased
or contact Whirlpool at 1-866-363-9472.

pipe section and one on the outgoing metal water pipe
section. Be sure that the filter head, fittings and valves
are between the two ground clamps.
b. Connect the ground wire to the two ground clamps,
using the wire screw terminal on each grounding clamp.
Tighten securely.
