1. Open faucet and turn off cold water supply to relieve pressure.
2. Select and mark a location under the sink that allows ac-
cess for filter change. You will be connecting to the existing
line with 3/8” tubing and various fittings not supplied with
this filter assembly.
3. Using filter head assembly as a guide, fasten filter head as-
sembly to wall with fasteners. (See Figure 1)
Allow 3” clearance from bottom of replacement filter for
ease of removal.
4. Place a basin or a towel under the cold water supply valve.
Remove the cold side riser tubing between your cold water sup-
ply valve to your primary faucet connection.
5. Install faucet adapter fitting (not included, see optional kit
3MDWIKT) to faucet stem. This should be a snug fit. Do
not overtighten. (See Figure 2) Ensure the black gasket is
inserted into the faucet adapter prior to assembly.
Determine length of 3/8” tubing (not included, see optional
kit 3MDWIKT) required from filter head outlet to faucet
adapter by holding tubing in place ensuring it is of appropri-
ate length. Do not kink tubing as this will impede water flow.
If necessary, loop tubing around to avoid it being kinked. Cut
tubing straight with a razor knife. (See Figure 3)
6. Insert 3/8” tubing from faucet adapter fitting into the filter
OUTLET fitting as shown in Figure 5.
7. Determine length of 3/8” tubing (not included, see optional kit
3MDWIKT) required from filter head inlet to cold water supply
valve by holding tubing in place ensuring it is of appropriate
length. Do not kink tubing as this will impede water flow. If nec-
essary, loop tubing around to avoid it being kinked. Cut tubing
straight with a razor knife. (See Figure 3)
8. Using a ferrule, nut and tube support (not included, see op-
tional kit 3MDWIKT), slide nut and ferrule over 3/8” tubing,
insert tube support and connect to the cold water supply
valve. (See Figure 4) Insert other end into filter INLET fit-
ting as shown in Figure 5.
9. Remove sanitary protective cap from filter. Ensure both
o-rings are present on the filter and are seated into grooves;
moisten o-rings with water. DO NOT use any petroleum
products to lubricate the o-rings.

• Allow a minimum of 3” (7.6 cm) clear space under the system to facilitate filter changes.
• All components should be accessible and have a sufficient amount of clearance on all sides of
the system to facilitate servicing.
