INLET VALVE INSTALLATION

INLET VALVE INSTALLATION – SAFETY WARNINGS
Caution! If inlet valve (also commonly known as a foot valve) is not properly installed and held
securely in place with a properly installed snap-ring, the inlet valve can be expelled from the rotor
when the piping is re-pressurized. Serious bodily injury can occur. Keep head and body parts away
from the rotor when piping is being re-pressurized.
Attention! Read and understand the inlet valve installation instructions outline below. If you are
unsure or not clear on any portion of the installation procedure, contact your local Hunter Golf
Distributor Representative or Hunter Technical Services at 800-733-2823 and choose option #3.
INLET VALVE INSTALLATION – G800 SERIES
Remove excess water from the rotor's body cavity. Inspect the upper and lower snap ring grooves
making sure there are no damaged or missing sections of plastic adjacent to (next to) the snap
ring grooves. Remove all plastic shavings or burrs of plastic that are found within the body cavity.
If needed, a small amount of Dow Corning™ #111 Valve Lubricant or pure petroleum jelly like
Vaseline™ can be used around the O-Ring on the inlet valve. In most instances, residual water
within the rotor's body cavity is sufficient lubrication for inlet valve installation.
Caution! Use of other non-specified lubricants can attack and deteriorate the plastic used in golf
rotors. Stress cracks or leaking caused by the use of improper lubricants are not covered under
warranty.
Inlet valve installation option 1 – G800 Series inlet valves are installed in the body using the G800
Valve Tool. Prior to using the tool, familiarize yourself with the individual features of the G800
Valve Tool. First, notice there are two metal hooks at the bottom of the tool (FIGURE 100). These
hooks are used to grab/hook the inlet valve during installation. The black plastic part of the G800
Valve Tool includes physical features that hold or nest the inlet valve and the white lower snap ring
to the tool during installation.

In order to engage the inlet valve and white lower
snap ring with the G800 Valve Tool properly, you
must be familiar with the pointing and alignment
features on the tool's black plastic part. First,
look at the three retaining screws on top of the
tool. Next, find the screw that has a pointer
arrow engraved around the head of the screw
(FIGURE 101). This pointer is used to indicate
the direction and alignment that the tool must
have as it is inserted into the rotor's body.
A second pointer arrow is located directly below
on the underside of the G800 Valve Tool
(FIGURE 102).
The underside of the black plastic part on the
G800 Valve Tool includes a feature that will
hold the white lower snap ring in position
during installation. The white lower snap ring
must be oriented correctly in the tool and the
raised areas at each end of the snap ring must
be facing the black plastic part on the tool. The
white lower snap ring must be loaded to the
G800 Valve Tool correctly. If the snap ring is
not loaded correctly, the valve cannot be loaded
to the tool.

To install the inlet valve into the rotor's body,
first load the white lower snap ring to the tool.
Hold the white lower snap ring in the palm of
one hand with the raised protruding ends of the
snap ring facing towards you (FIGURE 103). In
the other hand hold the G800 Valve Tool with
the metal hook end of the tool pointing towards
you. Compress the snap ring and place onto the
tool so that the two metal roll-pins at the bottom
of the black plastic part of the tool hold and
retain the white lower snap ring (FIGURE 104).
With the white lower snap ring loaded to the
underside of the G800 Valve Tool, load the inlet
valve to the tool. To do so, hold the inlet valve
in one hand with its top facing toward you
(FIGURE 105). Rotate the inlet valve in your
hand so that the communication port (located
on the side of the inlet valve) is at the 12:00
position while holding it in your hand. In the
other hand, hold the G800 Valve Tool by the
handle. The tool needs to be held so that the
pointer arrow (located at of one of the three
screws on top of the tool) is also oriented to
the 12:00 position.
