Do not install the drain saddle valve near a garbage
disposal;
otherwise, plugging of the waste water
line may occur. If discharging into a utility sink or
standpipe, an air gap must be provided. (Air gaps
must be 1” or greater above the floor rim.)
Note: Plumbing codes may require the use air
gaps. Please check with your local municipality.
Do not connect the R/O system drain line to the
dishwasher
drain line due to the fact back
pressures my cause the air gap to overflow.
Site reparation
Installing dealers may want to speak with
customers in advance and ask them to clean under
the sink to save time. If a basement installation is
advisable, check area to determine if extra fittings
or hosing are required. Upon arrival, it is a good
idea to check the condition of all plumbing for
potential leaks and advise customer so there will be
no misunderstandings in the event leaks occur.
Unit preparation
Open shipping carton, remove components and
check that all parts are present.
Check empty
storage tank to be sure air pressure is
approximately 7 psi. Adjust if necessary.
Note: Hand tighten all fitting connections to be sure they
are tight.
Installation steps
All plumbing must be completed in accordance with
state
and local plumbing codes. Some
municipalities may require installation by a licensed
plumber. Check local authority prior to installation.
1. Faucet installation
If the sink has a sprayer it may be disconnected for
faucet
installation. (Installing dealers should
discuss this with customers.) A pipe cap or plug will
be necessary to seal the sprayer connection.
To make the faucet mounting hole (if sprayer or
second hole is not used), check below to make sure
the drill does not interfere with anything below.
Center punch a small indent at the desired faucet
location. (2” flat surface is required, not exceeding
1-1/4” in thickness.) Drill the required pilot hole for
the chassis punch and tighten nut to cut the desired
hole size. Clean up sharp edges.
The faucet should be positioned so it empties into
the
sink and the spout swivels freely for
convenience. If sink has a hole that can
accommodate the RO faucet, no drilling is required.
Proceed with mounting the faucet.

Precautions must be taken to penetrate the
porcelain through to the metal base and prevent it
from chipping or scratching.
Tools required:
 Variable speed drill
 Relton porcelain cutter tool set
(7/8" or alternative size, 9/16")
