:
1.
Slide both C-shaped brackets into the valve housing as shown
(see Figure 4).
Note:
Use the upper mounting
holes in the valve housing to
maintain a water level about 4”
below the rim. Use the lower
mounting holes in the valve
housing to maintain a water level
about 2-3/8” below the rim.
2.
Attach each C-shaped bracket to
the valve housing with the 3/8”
mounting screws.
3.
Apply food grade anti-seize
compound to threads and connect
the water supply line.
4.
Position the automatic float valve assembly over the tank rim.
5.
Thread the thumb screws through the C-shaped brackets and tighten.
6.
Test automatic float valve operation.
Wide Rim Tank Mounting
(Models TM830T & TM830AS)
:
1.
Slide both L-shaped brackets into the valve housing as shown
(see Figure 5).
2.
Attach each L-shaped bracket
to the valve housing with the
3/8” mounting screws.
3.
Attach a C-shaped bracket to
each L-shaped bracket with
the 3/8” mounting screws.
Note:
There are two positions
on the L-shaped bracket
which allows you to adjust
for varying rim widths.
4.
Apply food grade anti-seize
compound to threads and
connect the water supply line.
5.
Position the automatic float valve assembly over the tank rim.
6.
Thread the thumb screws through the C-shaped brackets and tighten.
7.
Test automatic float valve operation.
Extra Wide Rim Tank Mounting
(Models TM830T & TM830AS)
:
1.
Slide both L-shaped brackets into
the valve housing as shown
(see Figure 6).
2.
Attach each L-shaped bracket to
the valve housing with the 3/8”
mounting screws.
3.
Apply food grade anti-seize
compound to threads and
connect the water supply line.
4.
Position the automatic float
valve assembly over the tank
rim.
5.
Attach each L-shaped bracket to
the tank rim with two (2) self tapping screws.
Note:
Pre-drill the tank rim at the desired automatic float valve mounting
location with a 1/8” drill if necessary.
6.
Test automatic float valve operation.
1.
Familiarize yourself with all of the automatic float valve components.
a.
Open the loose parts bag and inventory the contents.
b.
The plastic orifice insert and hose washer is already assembled in the
valve housing. Make sure the orifice insert and washer are firmly
seated against the valve housing.
c.
The rubber valve seat is already
pinned to the float. Make sure the
seat and pin are firmly seated against
the float.
2.
Position the float assembly inside
the valve housing and slide the large
2-1/4” cotter pin through the housing
and the float assembly (see Figure 1).
Spread the ends of the large cotter
pin open slightly with pliers. When
properly installed, the float assembly
should pivot freely on the cotter pin
inside the valve housing.
