System Installation
1. Determine Mounting Location
Warning: Before drilling mounting holes, locate any hidden electrical wires or plumbing behind the
mounting surface. Note adjacent equipment which may interfere with system fastening screws.
A. Fasten mounting bracket to mounting surface (screws not included). (Per Section 3 below)
Important: Allow a minimum of 3” (7.6 cm) free space underneath system required to
change filter.
B. Remove the cap from cartridge. Inspect the cartridge for any damage.
C. Make sure the o-rings are present and positioned correctly in grooves. Moisten the o-rings with
water.
D. Connect the replacement cartridge to head/bracket assembly. Align tabs with head/bracket assembly
and push up until cartridge stops, then rotate 1/4 turn to the right to secure.
E. Attach vinyl vent tubing (provided) to vent boss (Fig. 1.A) by pushing the tube onto the boss until it is snug.
F. Run tubing from vent boss through one of the tubing holes in bracket. Run tubing to drain or bucket during
cartridge change-out.
2. Cold Water Supply
Warning: Make sure cold water supply valve is turned off prior to installation.
Note: A proper length of 3/8” O.D. polyethylene or soft copper tubing is required for installation (not
included). Installation must comply with existing state and local plumbing codes.
Note: Additional fittings may be required.
Note: Arrange tubing so that there are no sharp bends. Leave some “play” in the tubing for ease of
servicing, then cut tubing to the desired length. Shorter tubing lengths ensure better flow rates.
3. Mount System
A. Select fasteners (not included) and tools
appropriate for the installation location.
(woodbeam, concrete, etc.) Warning: the
location and fasteners must support the
weight of the system when full of water.
B. Draw a line using a level on the mounting
surface.
C. Mark the locations for the fasteners either by
measuring the distance between the bracket
holes or using the bracket itself.
D. Drill holes for the fasteners.
E. Allow 1/4”-3/8” (6-10mm) of each fastener to
protrude from the surface.
F. Install the head and bracket onto the
fasteners.
G. Tighten fasteners.
H. Install inlet (left) and outlet (right) piping. Be
sure to use PTFE tape. Important: Hexagaon
sockets on the head do not rotate. Do Not
Overtighten.

Troubleshooting Guide
Water does not flow from the filter
Check to see if the original water supply valve is open, allowing water to flow to the filter. Also, check for
crimps or sharp bends in tubing. Check maintenance schedule for cartridge change-out.
Water appears cloudy or air comes out of filter faucet
Flush filter to remove any carbon fines or trapped air in the filter and water lines. Longer flushing may be
required to eliminate air bubbles completely. Refer to Performance Data Sheet or Flush Instruction Card for
proper flush time.
4. Test System
A. Open cold water supply valve.
B. The system will pressurize. Check for leaks. If any leaks are present, refer to troubleshooting section.
5. Flush Filter
A. Make sure cold water supply is turned on.
B. Run water through the filter to flush in accordance with Performance Data Sheet. Any air left in the
system may temporarily cause the water to be cloudy.
C. Your system is now ready for service.

Replacement Cartridge Change-out Instructions
For Water Filtration System Model: DWS160-L
A. Grasp filter (see figures 1 & 2) and turn to the left (counterclockwise) until filter comes to a complete
stop (water automatically turns off). Water may leak momentarily from vent tube. This is normal.
Gently pull filter downward to remove (see figure 3).
B. Remove sanitary protective cap from new replacement cartridge.
C. Ensure both o-rings are present on the replacement filter and are seated into grooves; moisten o-rings
with water. DO NOT use any petroleum products to lubricate the o-rings.
D. Insert replacement filter into filter head assembly. Turn replacement filter one quarter turn to the right
(clockwise) until it stops. When fully engaged, the top surface of the filter will be flush with the bottom of
the filter head assembly.
E. Open cold water supply valve. Run water through the filter to flush in accordance with Performance
Data Sheet. Any air left in the system may temporarily cause the water to be cloudy. While system is
flushing, check for leaks. Repair any leaks as needed before continuing.
F. System is now under pressure and ready for use.
