VADA SUMP PUMP WITH VERTICAL FLOAT V-150VF INSTALLATION MANUAL
1. Turn the power on at the power point.
2. Put a small amount of water in the
tank/pit/well, enough to cover the pump
completely.
3. The float switch will rise and the pump will
start to empty the pit.
4. As the pit empties, the float switch will fall
and the pump will stop.
Note: There is a small port hole in the base of
the pumping unit. On occasion, this will expel
air bubbles should air become trapped within
the pump housing. This is a normal operation.
Under normal conditions, the Vada V-150VF
Sump Pump with Vertical Float requires low
maintenance and is simple to service.
To avoid possible failures, we recommend
periodically checking the flow and pressure
supplied and current absorption for the
following:
• A decrease in pressure. This is a symptom
of wear.
• An increase in current absorption. This is
a sign of abnormal mechanical friction in the
pump and/or motor which may be caused
by debris caught in the impeller.
CHECKING THE FLOW
1. Get a bucket of a known size (e.g. 10 litre
bucket) and place it near the Sump Pump.
2. Get a hose and connect it from the final
discharge point to the bucket.
3. When the pump is operating, time how long
it takes to fill the bucket.
4. Enter the bucket size and time it takes
to fill the bucket to the formula below.
1. Bucket size x 60 = V
2. V ÷ time is takes to fill the bucket =
flow in litres per minute
Example: I am using a
10L
bucket.
It takes
8.5 seconds
for the bucket to fill.
1. 10 x 60 = 600
2. 600 ÷ 8.5 = 70
Therefore, my Sump Pump is producing
70 litres per minute.
If the answer (litres per minute) is between
64 and 96, the sump pump is operating
within the optimum operating range.
Note: Optimum operating range is
4.3–3.2 metres head, 64–96 litres per minute.
OPERATION SERVICE & MAINTENANCE
Do not run pump dry. Ensure
that pump is submerged in water
before operating. Turn off power to motor and
remove plug from power outlet
before working on pump or motor.
