UFL-420/440 WATER FILTRATION SYSTEM

INSTALLATION (continued)
Locating and Mounting the System
Consider these points before mounting the system:
• Note the location of the water supply, drain, and
an appropriate electrical outlet when choosing a
mounting location.
• Remember to allow for access to the timer/
programmer controls.
• Do not mount the system above any electrical
equipment, or items that may be damaged if they
get wet.
• Install the system in a location that will allow for
future service access. Cartridge replacement will
be either through the top or bottom of the housing.
NOTE: Be sure to allow access to both the top and
bottom of the housing.
• Mount the system on a wall using appropriate
mounting hardware.
• Remember to consider the operating weight of
the system when choosing mounting hardware.
Depending on the type of wall the system is being
mounted to, wall reinforcement may be necessary.
Mount the filtration unit using the Mounting Bracket
(Figure 2) using 1/4” by 1” bolts or bolts of the metric
equivalent.
INLET WATER PLUMBING
It is recommended that the inlet water plumbing line be
1” NPT or larger. A shutoff valve (not supplied) should
be installed in the line leading to the system. The valve
should be mounted close to the system inlet and sized
properly for the inlet plumbing line.
It is also recommended that a “T” or Cross Fitting (with
cap or plug) be installed between the inlet valve and the
system Inlet. This fitting can be used for draining and
sanitizing the system and downstream plumbing.
The system should only be connected to the cold water
line.
To ensure that the highest quality water is produced
from the system, the plumbing leading to the filter
system must be flushed clear of all debris before the
system is hooked up. Before making the connection to
the inlet of the filter system, hold a bucket or other con-
tainer at the inlet water line and slowly open the inlet
water valved. Allow the pipe to flush until all debris is
removed.
PERMEATE LINE PLUMBING
To ensure the highest quality and safest water, it is
recommended that a check valve (to prevent backflow)
be installed in the water line after the permeate connec-
tion. This will help prevent possible contamination of
the filter system due to other equipment downstream.
The check valve (not supplied) should be mounted
close to the system outlet, and sized properly for the
plumbing line. Check with local codes for the proper
specification.
