F. Make Initial Tubing Connections
It is advantageous to make some of the tubing
connections at this time, since the under-sink work
area is not so cramped and access to the
components is easier.
G. Install the Purification Assembly and
Storage Assembly
The purification assembly is usually mounted to the
right or left sink cabinet sidewall, taking into con-
sideration the space available and the tank
location. Generally, the tank is placed in the rear of
the cabinet while the purification assembly is posi-
tioned toward the front for cartridge accessibility.
To mount the purification assembly elevate at least
2" off the cabinet floor and, while keeping level,
mark the location of the mounting holes on cabinet
sidewall. Make small pilot holes with an awl or drill
and screw in the two mounting screws, leaving just
enough protruding to allow bracket mounting slots
to slide over them.
NOTE: If the cabinet sidewalls are not of solid
construction, the purification assembly can be set
on the cabinet floor and held against the sidewall
with the mounting screws.
The tank may be oriented either vertically or
horizontally. It is generally placed to the rear of the
cabinet but can be set in the front center (between
the sink basins) for ease of access if space permits.
H. Make Final Tubing Connections
With all of the components in place, the final tubing
connections can be made. When routing tubing
between components, several guidelines should be
observed.
Tubing runs should generally follow the con-
tour of the cabinets rather than interfere with
the cabinet storage area.
Strive for neatness and an orderly tubing
“flow” using fasteners (e.g. insulated
staples) to secure the tubing. Cut tubing to
the desired length.
Arrange the tubing so there are no sharp
bends and leave some “play” in the tubing
for ease of servicing.
Try to keep the tubing from the purification
assembly to the tank and faucet as short as
practical for good flow.
I. Install Ice Maker Hookup (optional)
Note: Check with refrigerator manufacturer for
compatibility with your refrigerator model.
The RO drinking water appliance can be connected
to any standard refrigerator ice maker or ice
maker/water dispenser. It should never be
connected to a commercial type bar ice maker.
Hooking up an ice maker involves connecting a tee
with shut off valve into the faucet tubing and routing
tubing over to the refrigerator. Do not hookup to
existing copper tubing.
Before turning off the existing tap water supply to a
refrigerator ice maker, always shut off the ice
maker first (usually by lifting the lever arm above
the bin to the upper most position). The ice maker
should only be turned on again after the RO system
has been drained several times and the tank has a
full supply of water.
NOTE: Before any service is performed on the RO
system, always turn off ice maker valve and the ice
maker unit. Only turn on when system is operating
and tank is full.
J. Start up the System
1) Double check that all connections are
secure.
2) Turn on feed water valve and check for
leaks. If any leaks are noted, turn off valve
and correct before proceeding.
3) Turn on storage tank valve and open faucet
until a steady stream of water flows. Close
faucet, wait at least 5 minutes and carefully
check for leaks. Correct as necessary.
K. Flush System of Preservative and Check
Operation
1) Lift faucet handle and allow tank to drain
completely of sanitizing solution. DO NOT
USE THIS WATER. When tank is empty,
the faucet will steadily drip. This is the rate
water is processed by the RO system.
2)
With faucet handle in “up” position, measure
the rate of the steady drip from spout. Use a
graduated cylinder (in milliliters) and watch
with a second hand to calculate
approximate production in gallons per day
(milliliters per minute X 0.38 = gpd).
