MAINTENANCE (continued)
Changing the Interval Setting
Resetting the Timer Program
During the normal operation, the system will flush accord-
ing to the set interval. It is possible the system will flush at a
time of high water use. If this poses a problem, the controller
can be reset. Unplug the power supply, wait for 5 seconds,
and then plug the power supply in. When power is restored
to the controller, it will automatically enter Flush Mode. The
controller will then begin timing from the point when power is
restored based on the interval setting selected.
Check Permeate Tank Air Pre-Charge
It is recommended the permeate tank air charge be checked
every six months.
Tools and supplies required:
• Air Pressure Gauge, 5‒40 psi range (0.3‒2.7 bar) with
tire valve (Schrader Valve) connection
• Source of compressed air (manual bicycle tire pump or
air compressor)

CAUTION
Changing the flush interval may cause the Ultra Filter
to plug prematurely and may reduce the life of the filter.
Consult the factory for more information.
CAUTION
Air pre-charge should only be checked and adjusted
under zero system pressure. The system must be
depressurized before checking the tank pre-charge.
Do NOT adjust the tank air pre-charge with the system
under pressure.
CAUTION
Be careful when adding air to the tank. Do NOT add too
much air pressure to the tank.
Though not recommended, the interval setting on the
Universal Pulse Controller can be changed. If the setting must
be changed, use the chart below. Press and hold the corre-
sponding button. After 5 seconds, the Button LED will turn on.
After 10 seconds, the Flush LED will also turn on.

1. Depressurize the system by closing the Inlet and Outlet
Valves and opening the Rinse Valve. Make sure the
Permeate Tank is fully drained.
2. Unscrew the protective cap from the air valve on the
tank.
3. Use the pressure gauge to check the tank pre-charge
for pressure.
NOTE: If any water comes out the air valve, the tank
bladder has ruptured and the tank needs to be replaced.
4. The permeate tank should have a pressure of 10 psi.
• To add pressure to the permeate tank, use a manual
bicycle tire pump or other source of compressed air.
• To release pressure from the permeate tank, press
the center pin on the air inlet valve.
5. Once the permeate tank is at 10 psi, replace the
protective cap on the air valve.
6. Pressurize system by closing the Rinse Valve and
opening the Inlet and Outlet Valves.
