Purenex Multipure Aqua RO System - Manual (Page 4)

A dripping or gurgling sound may be heard coming from the Air Gap hole in the faucet and drain when the
system is running. This is normal and in compliance with UPC Plumbing Codes.
Note: Porcelain sink surface material is extremely hard and can crack or chip quite easily.
Use extreme caution when drilling. Multipure Drinking Water Systems accepts no
responsibility for consequential damage resulting from the installation of faucet.
Most sinks are predrilled with 1 1/2” or 1 1/4” diameter holes (if you are already using it for a
sprayer or soap dispenser, see step 1).
Step 1 Determine desired location for the faucet on your sink and place a piece of
masking tape on location where hole is to be drilled. Mark the center of
the hole on the tape.
Step 2 Using a variable speed drill on the lowest speed, drill a 1/8” Pilot hole
through both porcelain and metal casing of sink at the center of the desired
location. (If drill bit gets hot, it may cause the porcelain to crack or chip).
Step 3 Using a 1.00” or 1.25” hole saw, proceed to drill the large hole. Keep drill
speed on the slowest speed and use lubricating oil or liquid soap to keep the
hole saw cool during cutting.
Step 4 Make sure the surroundings of the sink are cooled before mounting the
faucet to the sink after drilling. Remove all sharp edges with a file.
Punch a Hole for Faucet in a Stainless Steel Sink
NOTE: If mounting faucet to a Stainless Steel Sink, you will need a 1/2” and 1 1/4”
Hole punch. The faucet opening should be centered between the back
splash and the edge of the sink, ideally on the same side as the vertical
drain pipe.
Step 5 Drill a 1/4” pilot hole. Use a 1/2” Hole punch and an adjustable wrench to
punch the hole in the sink.
The faucet can now be installed.
