Installation Instructions
A. Determine System Location (Figure. 1&2)
The appliance can be located under a sink or
in a basement depending on space availability and
the customer's preference. If a basement installation
is selected, additional tubing, hardware and fittings
may be needed and a hole will have to be made
from inside the cabinet, through the floor, to the
basement. Never install in an area of the home
where temperature is freezing as damage to the
system will result.
The exact placement of the various compo-
nents of the appliance will vary from installation to
installation. The installer, in conjunction with the
customer, must decide on where to place the faucet,
tank and purification assembly by balancing the
homeowner's convenience with ease of installation
and servicing.
Considerations for an icemaker or other
remote hookup should be predetermined, including
routing and any additional tools, fittings, and tubing
that may be required.
B. Prepare The Area For Installation
To save time it is often advised to call the
customer and request they clear under the sink prior
to arrival. Otherwise, remove supplies from under
the sink and stack them neatly away from the work-
ing area. Arrange a light for the work area, if neces-
sary.
If a basement installation is called for, deter-
mine where components will be located and how
they will be mounted. Special mounting brackets
and hardware may be necessary to secure the sys-
tem to a wall or ceiling joints.
Inspect cold water supply line and drain to
determine if any special fittings, in addition to what
is included in the kit, are required.
NOTE: It is a good idea at this time to check the
condition of the customer's undercounter plumbing
for any existing or potential leaks. The customer
should be advised of any problem so there is no
misunderstanding of who is responsible.
C. Prepare The Appliance For Installation
Open shipping carton and remove compo-
nents. Check that all installation parts are present
which includes the purification assembly, storage
tank, faucet, installation hardware and tubing.
Check that the air supply in the empty tank is
approximately 7 psi. Adjust if necessary.
If optional percent rejection monitor is selected,
probes should be installed at this time. Follow instruc-
tions that come with the monitor.
The saddle tapping valve supplied is
designed for use with 3/8" to 1/2" O.D. soft copper
supply tubing (plain or chromed) and rigid metal
pipe (see below). Do not use with flexible ribbed
supply tubing which has too thin a wall thickness
and requires special hardware. Optional feed valves
can be specially ordered from the factory for this
purpose. Also refer to figure 6 on use of the "Push
In" plastic fit- tings.
Soft Copper Tubing Installations:
A) Turn off cold water valve under the sink, or main
valve for the house.
B) Before installing saddle tapping valve, make sure
piercing lance does not protrude beyond rubber gas-
ket. See instructions on bag.
C) Assemble both halves of saddle tapping valve on
copper tubing.
D) For 3/8" O.D tubing, use bracket with side projec-
tions to prevent distortion of tubing. Use "V" side of
bracket for all larger size tubing. Tighten screws
evenly and firmly - brackets should be parallel. Do
not deform tubing. See diagram.
E) To pierce soft copper tube, turn handle clockwise
until it is firmly seated. The valve is closed in this
position.
F) Turn on main supply valve to pressurize cold
water line. Check for leaks. With a wrench, tighten
nut/seal around valve stem.
G) Connect length of orange 1/4" tubing to the feed
water valve, using brass compression nut, insert,
and plastic sleeve. See diagram.
NOTE: For basement installations, a longer length
of feed water tubing may have to be used.
IMPORTANT: Some local plumbing codes may
prohibit the use of saddle-type valve connec-
tions. Optional feed valve assemblies can be
specially ordered from you supplier. See page
11 for further information.
Rigid Metal Pipe Installations:
A) Turn off cold water supply valve and drain the
line to prevent spillage.
