CB Tech
Nanomesh™ Stage II Filter:
The CB Tech Nanomesh™ Stage II filter should be changed after the Stage I filters
have been changed four times.
Causes for System Shut Off
Once the system has been primed, the CB Tech WaterBox™ begins filtering water.
There are two conditions that can cause the system to automatically shut off during
filtration operations:
Excessive backpressure: The CB Tech WaterBox™ is equipped with a 70 psi bypass
valve. If the system backpressure exceeds 70 psi, a valve will open and water will
recirculate within the pump. If this occurs, check that the inlet and outlet hoses,
pump filter screen and intake adaptor are free from obstruction.
Current surge: The CB Tech WaterBox™ is equipped with a circuit breaker to protect
against an electrical current surge. If the circuit breaker trips, turn power OFF to
automatically reset the circuit breaker and then back ON to resume operations. If
the circuit breaker continues to trip, confirm that the power source is operating at
the selected voltage (12 VDC, 24 VDC, 115 VAC, or 230 VAC). If the power source is
operating correctly and the circuit breaker continues to trip, there may be a problem
with the pump. In this case, contact CB Tech for system service.
E. System Shutdown and Storage
1.
When you are finished using the CB Tech WaterBox™, switch the power to the OFF
position and unplug the power cord from the power source. Remove hoses and open
valves to allow them to drain. Allow both hoses to air dry completely.
2.
If there is
any risk of the unit being exposed to temperatures below 32
o
F (0
o
C)
completely drain all of the water from the filter housings and pump as described
under the Changing the Filter Cartridges section.
3.
If the unit will not be exposed to freezing temperatures and will be used again within
72 hours, the filters should remain in place and water left in the filter housings. The
unit should be stored out of direct sunlight.
4.
If the unit needs to be stored for an extended period of time, all water should be
drained from the system and the filter cartridges removed and discarded.
