MODEL 1200 DOG WATERER
READ OWNER’S MANUAL
CAREFULLY BEFORE INSTALLING.
Nelson Model 1200 Automatic Waterer
provides a constant supply of fresh water
and eliminates the hassles and expense
of manually watering. The Model 1200
is made from tough 304 stainless steel, is
virtually maintenance-free and is designed
for easy cleaning.
WARNING! Install waterer near
floor drain when locating waterer in
a building - homes, garages, etc.
Locate waterer near a floor drain
so that if waterer overflows, water
will go down floor drain and not
damage building. Failure to locate
waterer near a floor drain could
result in water damage to building
if waterer overflow occurs.

OPERATION
Water passes through float valve into the
drinking bowl. As the bowl fills with water, the
float rises until water is shut off due to action
of the float arm. When the animal drinks,
water is removed from the bowl lowering the
float. This reduces the pressure of the valve
seat on the valve orifice, allowing water to
enter the bowl.
Pipe or Tubing Connection.
More permanent waterline materials may
include iron pipe, copper pipe, brass pipe,
copper tubing and plastic tubing. Connect
waterline making certain to locate a pipe
union or a compression connector in the
line near the valve as it may be necessary to
disconnect the water line to remove float valve
for maintenance. It is recommended that
a waterline shut off valve be installed in the
waterline where it is handy to reach. Water
can then be easily shut-off when cleaning
or performing maintenance. Waterline
can be brought to the waterer from above,
below, behind or straight out, which ever is
convenient. Use Teflon thread sealing tape on
1/8” FPT connecting waterline to valve.
Attach wall bracket to wall using two top holes
and center bottom hole. The wall bracket must
be level, requiring the use of a level when
locating the holes on the wall. If the waterer
is installed inside, locate it near a drain for
cleaning convenience.
Mount on Kennel Pole - The pole mounting
bracket kit (Accessory K2) contains the
necessary bolts, nuts and brackets to mount
the waterer to most kennel poles. Attach wall
bracket to pole using top four holes. Locate
waterer such that the top holes in the wall
mounting bracket are a minimum of 9 inches
above the floor. This allows enough room to
remove the drinking bowl for cleaning. If the
waterer is installed inside, locate it near a drain
for cleaning convenience.
WATERLINE CONNECTION
Faucet Connection. Mounting the waterer
next to an outdoor faucet is a popular
installation. Nelson’s garden hose adapter
(Accessory K3) provides a fast and easy
connection. The garden hose adapter consists
of a one foot length of stainless steel braided
garden hose with fittings on each end for
easily connecting to an outdoor faucet.
The faucet also serves as a handy shut-off
valve to be used when cleaning the drinking
bowl. To utilize a single faucet for multiple
purposes consider obtaining an inexpensive
2-way faucet adapter available at most home
improvement centers and hardware stores.

ASSEMBLY
Step 1. Mount Wall Bracket on Wall or
Kennel Pole
Wall bracket must be level.
Mount on Wall - Three 5/16” diameter
bolts are required for mounting wall bracket
to wall. Four carriage bolts (1 3/4” long X
5/16” diameter) and nuts are included with
the Nelson’s pole mounting kit (Accessory
K2). The carriage bolts may or may not
work with the type and thickness of your wall.
It may be that 5/16” lag bolts are desirable.
Lag bolts can be obtained at a local hardware
store. Locate waterer such that the top holes
in the wall mounting bracket are a minimum of
9 inches above the floor. This allows enough
room to remove the drinking bowl for cleaning.

Step 2. Attach Valve to Wall Bracket
1. Remove washer and valve nut located on
valve.
2. Valve can be located on either right or left
side of wall bracket. Place valve body through
hole such that valve body fits in hex hole on
bracket. Secure valve to wall bracket with the
washer and nut removed earlier. Valve should
be installed with float arm hanging directly
downward. Push black hole plug in hole on
opposite side of valve.
Step 3. Attach Drinking Bowl
to Wall Bracket

Page 3
1. Mounting drinking bowl to wall bracket
requires the hardware in the plastic pack (2
Phillips head
screws, 2 hex
Screws
nuts and 1 acorn
nut).
2. Thread
both screws into
holes in back
two corners of
drinking bowl.
Thread screws
from the top with
screw heads up.
Tighten screws
Latch
Bar
so that screw
heads just make
contact with
surface of bowl
then back out
2 ¾ complete
rotations. The
length the
screws are backed out of drinking bowl
determines how tight the latch bar operates.
The latch bar locks and releases the drinking
bowl from the wall bracket. The further the
screws are backed out the looser the latch bar
operates. Conversely, the further the screws
are set into the drinking bowl the tighter the
latch bar operates. Some experimentation
may be required to find the optimal setting.
3. Once proper setting of screws is
determined, lock the screws in place by
installing a hex nut on bottom of each screw.
4. Slide latch bar into retainer on wall
bracket, handle up or down, whichever you
prefer. The latch bar will go either way with
the handle on the right or left side of waterer,
whichever is convenient.
5. Lift drinking bowl upwards onto wall
bracket such that screw heads on bowl pass
through bracket and through latch bar. Slide
latch bar so as to capture screw heads in slots
on latch bar.
6. Place float guard over screw in center of
mounting bracket
and secure with
Float Guard
acorn nut, hand
tighten.
Cleaning and
Sterilizing. Clean
drinking bowl
as required.
To remove the
drinking bowl
from the wall
bracket, line up
latch bar so that
bolts on the back
of the drinking
bowl slide through wall bracket. Bowl may
be sterilized with a disinfectant solution, but
make certain the float and float arm are also
immersed in the disinfectant. After disinfecting,
thoroughly rinse with water.
Removing Mineral Deposits. Mineral
deposits can be removed from the drinking
bowl by soaking the bowl in a water-vinegar
solution. Remove the drinking bowl from the
wall bracket. Fill the drinking bowl up with
enough water to cover the mineral deposits.
Mix in one cup of vinegar. Let the bowl soak
for 24 hours and wipe clean.
Replacing Rubber Valve Seat. Over time,
rubber seat can harden and tear. If wear
on rubber valve seat causes valve to leak,
resulting in overflow, replace rubber valve seat.
1. Turn off the water supply at shut-off valve.
2. Remove the Acorn nut and the Float Cover.
3. Place your index finger inside the front of
the valve cap and pull gently towards the
front of the waterer. While pulling out on
the valve cap, use the index finger of your
other hand to push the valve cap away
from the valve. This will allow the Float arm
assembly to release from the valve body.
4. Remove the Rubber seat from the Float arm
assembly and replace with a new Rubber
seat.
5. Replace the Float arm assembly into the
Valve body.
6. While holding the float assembly in place,
slide the Valve cap over the Valve body until
you hear and feel the Valve cap snap into
place.
7. Replace the Float Cover and Acorn nut.
8. Turn on the water supply.

Part No. 1220
Tightening / Loosening Bowl Latch. The
length the screws are backed out of drinking
bowl determines how tight the bowl release
latch operates. Tighten screws so that screw
heads just make contact with surface of bowl
then back out 2 ¾ complete rotations. The
further the screws are backed out the looser
the bowl release latch operates. Conversely,
the further the screws are set into the drinking
bowl the tighter the bowl release latch
operates. Some experimentation may be
required to find the optimal setting.
