START-UP
Turn on the water supply to bring the Pressure Lite system
to operating pressure (approximately 1 minute).
Check for leaks. Slight retightening of leaking connec-
tions should stop any seal leaks.
Flush and repressurize the toilet three times to stabilize
the system. Some water may appear in the outlet manifold
during the flush, but constant remaining water in the outlet
manifold after flushing indicates a malfunction.
GAP CLEARANCE
If toilet does not activate, the gap between the trip lever
and piston actuation arm may need to be reset. Make sure
the trip lever handle is installed and trip lever nut is tight.
This is a left-hand thread; turn it counterclockwise to
tighten.
Make sure the water supply is on, and supply line water
has stopped flowing into the toilet.
Turn the piston nut until there is a 1/32” to 1/16” gap
between the trip lever and piston actuation arm. Turn the
piston nut clockwise to reduce the gap.
NOTE: Loss of gap clearance adjustment could cause
leakage into the toilet bowl due to the piston not sealing
properly. This condition could cause a continuous flow of
water. If the problem is not corrected after adjustment,
refer to the troubleshooting chart.

SCREEN CLEANING
Shut off the water supply. Flush the toilet. Hold the trip
lever down for approximately one minute to drain the
water from the tank assembly. Disconnect the water
supply line.
To clean any remaining water from the screen adapter,
backflow preventer, and pressure regulator, disconnect
the supply hose from the backflow preventer by turning
the nut counterclockwise. Disassemble the screen
adapter, and clean the screen with a medium to hard
bristle brush. Replace the screen if necessary. After the
screen is clean, reassemble in reverse order making sure
the screen is assembled correctly.
