Step 1: Location
a) WM-120 to be mounted to a wall with feed
water supply, drain and storage tank within
15 ft. of location. Controller box to be
mounted within 6 ft of WM and electrical
outlet within 12 ft. Review general
plumbing layouts as references for
installation of pre- or post-treatment
equipment on page 3.
b) Mounting location should have clearance of
2 inches on both sides including; 2 inches
from the bottom of pre -filter housing for
filter changes. See figure 1, page 2.
Step 2: Mounting WM to Wall
a) The WM-120 mounting bracket has (2)
mounting keyholes that are 10.75 inches on
center.
b) The WM-120 will have an approximate
weight of 75 pounds. Caution needs to be
used when mounting unit to the wall. Use
molly bolts or self-anchoring screws with
¼” diameter heads. For sheet rock wall at
least (1) mounting screw should be located
at a wall stud.
c) The WM-bracket is designed so that if using
mounting screws with a head size of ¼” or
less in diameter, the head of the screw will
pass through the keyhole. See drawing
below)
Figure 2
d) When screwing screw into wall, allow 1/16”
clearance between the screw head and the
wall. The WM-bracket will slide between
the screw head and the wall.
Step 3: Connecting to Feed water supply:
The WM may come with either a Self-Piecing
Valve, or Easy Tap Adapter.
WM-120 supplied with a Self-Piercing Valve
follow Processor A.
WM-120 supplied with an Easy Tap Adapter
follow Processor B.
Processor A
TO INSTALL SELF-PIERCING VALVE ON
COPPER TUBE
CAUTION:
Do not turn handle before or while
installing (Self-Piercing Valve) be sure the
piercing lance does not protrude beyond the
rubber gasket.
Failure to do this may result in
damage to the piercing needle.
a) Turn off the water supply at the location of
installation of the Self-Piercing Valve.
b) Assemble the Self-Piercing Valve on copper
tubing. For 3/8” OD tubing using Patent
Pending bracket with side projections to
prevent distortion of tubing. Use “V” side
of bracket for all larger tubing.
c) Tighten screws firmly and evenly, brackets
should be parallel.
d) Connect ¼” green tubing of the unit to the
Self-Piercing Valve as shown in figure C.
e) Turn the handle clockwise until you feel it is
firmly seated. Note: you have now pierced
the copper tube and the valve is closed.
f)
Turn on the cold water supply, then turn the
handle counter-clockwise to open the self-
piercing valve.
g) Check for leaks and repair if any.
TO INSTALL SELF-PIERCING VALVE ON
STEEL OR BRASS PIPE
a) Shut-off the water supply and drain the line.
b) Drill a 3/16” (0.24 cm) hole in pipe. Use a
hand drill to avoid shock hazard.
c) Turn handle to expose lance beyond the
rubber gasket no more than 3/16” (0.24 cm).
d) Place body of valve over the hole so that the
lance fits into the hole.
