Pressure Regulator Replacement; Attaching The Flange Replacement Lid - Hunter G800 Series Owner's Manual

PRESSURE REGULATOR REPLACEMENT

I TABLE OF CONTENTS
To raise the pressure setting on the variable setting regulator, turn the adjusting knob clockwise
(FIGURE 146). Each full clockwise turn will increase the pressure approximately 10 PSI. Use the scale
on the side of the regulator's body to estimate pressure.
To lower the pressure setting on a variable setting regulator, turn the knob counter-clockwise
(FIGURE 146). To obtain a more accurate setting when reducing the pressure, it is highly
recommended to take the setting down to approximately 10 PSI below the desired pressure
setting and then turn the knob clockwise to the desired setting.

PRESSURE REGULATOR REPLACEMENT
To replace the Pressure Regulator, first disengage the Solenoid and Pilot Valve from the flange
compartment. This action will create easier access to the Pressure Regulator. Next, notice the two
tubes that are connected at the base of the Pressure Regulator (FIGURE 147). The tube entering
the center of the Pressure Regulator is the inlet and it comes from the top fitting in the Pilot Valve.
The tube that is offset from the center is the outlet and it goes to the rotor's body wall. One of the
TTS rotor's valuable features is that the water discharged from the valve circuitry is vented into
the rotor's body and then out the nozzles.
To replace the Pressure Regulator, use side-cutters or blade to make clean cuts in the tubing at
points just before they enter into the Pressure Regulator. Next, connect the inlet tube going into
the center of the new Pressure Regulator. To connect, pinch tube's end with fingers in order to
make the opening as round as possible. Place the end of the tube to the Pressure Regulator's
center connection point then press and wiggle into position. Make sure the tube goes in as far
as possible. Next, connect the outlet tube going to the rotor's body wall. If removed, attach the
Solenoid and Pilot Valve to the flange compartment. Finally, insert Pressure Regulator into any
convenient available location within the flange compartment.

ATTACHING THE FLANGE COMPARTMENT LID
Take a moment for a final check to make sure
that all of the flange compartment components
have been installed properly. Place the flange
compartment lid into position and align the
Selector Cap to its hole in the lid. Press the
flange compartment lid into position and secure
with the stainless steel retaining screws
