16. SUCTION LIFT
The DT42 Pump is not the best type of pump for Suction lift. Suction lift is pumping out of a tank that is at a lower level or underground. You
should use a JET style of pump for suction lift applications. If however you decide to do so, follow the instructions below, but be aware that
Ascento is not obligated to provide technical support or field service if you have installed this DT42 pump in a suction lift application.
a) Fit a foot valve on the suction pipe in the tank, that is kept clear of sludge that will build up on the bottom of the tank over time.
b) The suction (intake) pipework must be ‘uphill’ all the way to the pump (only RISE, not rise and fall) and be perfectly airtight and be of
sufficient diameter (not less than 30mm internal diameter and greater diameter than the discharge) and be of suitable material that will not
collapse (suction pipe)
(c) A Check Valve should also be installed at the inlet of the pump, in most cases – check with your pump technician.
(d) For pipe lengths of greater than 3m for suction you must consult with a qualified pump technician as to whether the pipe sizing you are
using is suitable. Using incorrect pipe sizes will lead to problems.
(e) Suction lift installations are notoriously troublesome, and almost invariably it is not the pump that causes the problem. Leaking footvalve,
air leak into the pipe, slow water leak out of the pipe, humps & hollows in the pipe leading to air-pockets, debris caught in the pipework or
fittings, will cause “loss of prime” and pump failure/no water delivered. This is not a pump fault.
(f) Have the installation checked by a qualified pump technician to ensure it is done correctly, do not entirely rely on the instructions above as
it might not exactly suit your situation.
17. OVERLOAD PROTECTION
This pump has a built in thermal protection switch. The pump stops if a high-temperature condition occurs. The motor restarts automatically
after it has cooled down when the built in thermal protector resets itself. Or you may need to turn the power off and on again to reset it. If this
problem reoccurs - check per 15
18. IMPORTANT NOTES
(a) Do not switch the pump on and off frequently, as this will cause damage to the electronics and void warranty. (b) Do not attempt to adjust
the flow via the intake pipework (c) If there is insufficient water, the motor will stop. See 15 and also 19. (d) If the pump is idle for a long
period of time or in very low temperature, the water should be drained to avoid damage to the pump and/or stagnation of water. (e) After it
has been idle for some time, the pump turbine may become jammed. Turn off the power supply and remove the plug form the power outlet.
Put a small screwdriver through the fan cover at the back of the electric motor (ensure power is off) and gently move the fan, in order to turn
the motor. Remove the screwdriver and turn the power back on and re-test, if not successful you might need to repeat the same process
again.
DANGER!!!!
Keep the pump equipment protected from interference by pets, wildlife, children, infirm persons or incompetent persons.
WARNING!!!
This pump is designed for clean fresh water only, in non-hazardous locations.
It must NOT be used as a continuous duty fountain pump, or dirty water, or liquids other than water.
Install in well ventilated and well drained area.
19. PUMP CONTROLLER FUNCTION AND OPERATION:
Model: WaterPro PC15-QP
The pump controller fitted to this pump is designed to be almost completely automatic. Instructions and basic function;
a)
Use for CLEAN rainwater only – and fit a prefilter or Y-Strainer to the intake of the pump
b)
Do not operate on domestic generator power supply as this may damage the electronics
c)
Protect from direct sunlight to avoid UV damage to the plastic
d)
The pump controller will stop the pump if there is no water in it.
e)
It will not restart unless you press the restart button. Check for water first, the tank might be empty.
f)
After checking water is in tank try pressing restart. If it still says failure, or no water, check water is in the pump
g)
Occasionally when the pump re-starts after a run-dry event, some air might come through the lines, this should do no harm.
h)
If it is dry for a long time - no rain - it is best to turn the power off to the pump, at the power outlet, see 18
