15. PUMP PRIMING AND START UP
(a) Dry operation will destroy the pump seals and is not covered by warranty.
(b) Remove the pressure controller by loosening the barrel union, (or use the priming plug at the front of the wet-end, near the
inlet, but that is slower) and completely fill the pump chamber with water before starting.
(c) Turn the pump on, if water does not flow, turn it off and repeat step 15(b) again, and if it is suction-lift the entire suction pipe
may need to be pre-primed.
(d) If it still does not pump water, check the intake and discharge pipework is free from airlocks, or any other obstructions and refer
to the TROUBLESHOOTING guide.
16. SUCTION LIFT
Suction lift installations are notoriously troublesome, and almost invariably it is not the pump that causes the problem, we
recommend using a submersible pump system if at all possible.
NOTICE!!
Suction Lift is NOT SUITABLE for most Rain-to-Mains Changeover Systems
–
unless you fit a float switch in the tank.
When pumping out of a tank that is at a lower level or underground, the inlet pipe must be:
a) Fitted with a foot valve 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 SWING Check Valve should also be installed at the inlet of the pump, in most cases.
(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. 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, will cause “loss of prime” and pump failure/no wate
r delivered.
FAILURE TO FOLLOW THESE GUIDELINES WILL RESULT IN LOSS OF PRIME (No Water in Pump)
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 as 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 (f) 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.
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:
The Pump Controller (sometimes referred to as the Pressure Controller) fitted to this pump is designed to be almost completely
automatic, and will restart itself if the pump runs out of water; you should not normally need to do anything. Instructions and basic
function;
a)
Use for CLEAN rainwater only
–
you must fit a prefilter or Y-Strainer to the intake (suction pipe) of the pump
b)
Do not use a low quality generator for power supply - see section 12 - 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 the pump
e)
It then rechecks for water several times over the period of about 20 minutes
–
it makes the pump start each time, to try
and “re
-
prime” itself (fill it back up with water)
It
might “crackle & gurgle”
due to air in it, as it tries to restart, this is normal
f)
If there is insufficient water to allow the pump to operate normally, the controller then switches off for 24 hours and tries
again. If insufficient water, it will try again in 24 hours, and continue to do that indefinitely until there is sufficient water
and the pump can operate normally.
g)
If it happens to do this in the middle of the night it can be annoying! In the morning, turn it off & on again after 30 seconds
and it will reset itself so it does the checking in daylight hours.
h)
Leak detection function: if the pump starts and stops 7 times or more in about 2 minutes, the pump may turn off
automatically. If this occurs, investigate what is leaking.
i)
You can reset the function back to the beginning anytime by pressing the restart button.
j)
If it is many days before it rains again (or you have your tank re-filled), turn off the power to the pump, at the power outlet
k)
Occasionally when the pump re-starts after a run-dry event, some air might come through the lines, this will do no harm.
