ULTRAFLOW WATER PUMP
ASSEMBLY
The Water Pump Assembly comes complete
with the water pump, container cover and
storage clip. The submersible pump needs
no priming and is extremely quiet in
operation.
ULTRAFLOW SMART SWITCH
APS01
The self-calibrating Ultraflow Smart Switch
has been designed to switch the pressure
controlled submersible Ultraflow Maxi Pump
fitted in caravans.
The inline adaptive
system measures the
performance of your
submersible water
pump and constantly
adjusts the start and
stop pressures to suit
the water pump and
battery voltage. If the
water container runs
dry the water pump is stopped after a short
time, and the pressure switch locks out to
prevent damage to the water pump until the
water is refilled. Due to the integrated
processor there are not adjustments to be
made.
SAFETY INSTRUCTION
- Use the switch only in a technical flawless
condition.
- The power supply has to be rated with 6.3
AT (slow).
- The cable terminals have to be fitted
completely and firmly.
- The system has to be drained in danger of
frost.
- In combination with a mains water supply
a pressure reducer is absolutely
necessary.
- If the safety instructions are not
respected, it results in forfeiture of our
product liability.

PRINCIPLE OF OPERATION,
MAINTENANCE
First Steps
Fill the aquaroll with water and fit the pump
into the socket.
Close all taps and drain valves.
Switch on the on-board power supply.
Switch on the pump power supply.
Initialisation
Now the Truma Ultraflow Smart Switch looks
for the pump to raise a system pressure
above 0.7 bar. If this condition is met the
pump continues to run for approximately 7
seconds until it stops. Whatever maximum
pressure is reached is remembered by
Ultraflow Smart Switch and providing that
the voltage across the pressure switch is
maintained this is referred to for future pump
operations.
