Installation Guide
Step 3
Prepare the Sink for Spigot Installation
The most convenient installation would allow the use of an existing spray attachment hole. If the spray
attachment hole is not available, then follow the basic procedures outlined below.
Drilling a stainless steel sink:
A.
Mark the sink location for the center of the spigot.
B.
Impact punch the sink top to provide a starting point for the drill bit.
C.
Drill a 1/4-inch pilot hole in the sink using a high-speed drill bit.
D.
Drill a 1/2-inch diameter hole to accept the bolt of a 1-inch Greenlee Chassis Punch.
E.
Set the punch and turn the nut with a wrench to cut the hole. Follow Greenlee instructions.
Drilling a porcelain clad steel or cast-iron sink:
A.
Mark the sink location for the center of the spigot. Be sure
the location you select is not over a reinforcing rib. Check the
location from under the sink.
B.
Grind away a 1-inch diameter circle in the porcelain
using a silicon/carbide wheel and high-speed grinder (See
Installation Tool List
), down to the metal surface of the sink.
(See Figure 4).
C.
Impact punch a small indent in the center of the area
ground away.
D.
Drill a 1/4-inch pilot hole through the metal base using a
standard high-speed drill bit.
Caution:
Be careful when the drill is about to penetrate the base metal of the sink. Reduce the speed and
support the drill so the drill chuck does not impact the porcelain or enamel.
E.
Use the pilot hole as a guide to drill a 1-inch diameter hole with carbide bits to mount the spigot.
Step 4
Prepare the Air Gap Spigot Assembly for Installation
A.
Assemble the spigot with all of the components (See Figure 16) according to the spigot assembly
instructions included with the spigot.
B.
Feed the assembled spigot and tubing through the hole in the sink and fasten from under the sink according
to the instructions.
C.
Position the spigot for customer convenience and then secure the spigot on the sink.
Step 5
Install the Incoming Water Supply Valve
For installation with standard angle stop incoming water supply valve.
A.
Shut off the water at the angle stop valve.
B.
Use a wrench to loosen the compression nut on the angle stop riser tube.
C.
Install the incoming water supply valve onto the angle stop. Use the wrench to tighten the compression nut
on the incoming water supply valve. Do not overtighten!
D.
Reconnect the riser tube to the other end of the incoming
water supply valve. Do not overtighten!
Caution:
A longer riser tube assembly will be required if a
gentle loop cannot be made. (See Figure 5).
E.
Remove the red locking clip from the incoming water
supply valve. Fully insert the blue 3/8-inch tube into the speedfit
connection and replace the red locking clip. The new incoming
water valve can be swiveled to position the tubing out of the way.
F.
Make sure the incoming water supply valve is off before
turning the angle stop valve on. Check for leaks.
