• The unit must be used with cold water supply only.
The water hose must be at least ½" (13 mm) in
diameter.
• The water flow rate must not fall below 18 litres per
minute (LPM) (4 gallons per minute (GPM)), or the
pump might be damaged. The flow rate can be
determined by running water for one minute into an
empty container.
• The water supply temperature must not exceed 40
℃
(104
℉
).
5.3 Adjusting Water Pressure
•The water pressure can be adjusted using the 3 in 1
switch (5)
• Move the switch to
FAST
position to increase the
engine speed, thus increasing the water pressure.
Move it towards
SLOW
position to decrease the
engine speed, thus decreasing the water pressure.
