INSTALLATION GUIDELINES
Please read and follow the instructions which are to be read in conjunction with the diagrams on the earlier pages. Ensure all
installations are in compliance with any relevant Australian Standards, this is the installers responsibly. Warranty covers
manufacturing defects of the pump; it does not include faults in the installation. Note that all warranty is voided if the instructions
are not followed. Use for CLEAN FRESH WATER only.
IMPORTANT INSTALLATION & WARRANTY
CONDITIONS
1) A “First-flush-diverter” or similar device must be installed, and /or a filter screen through
which all the incoming water passes before entering the tank, to prevent debris from
entering the tank.
2) Warning: when lowering Pump into Rainwater Tank: Use the rope supplied to lower the
pump into the tank. DO NOT USE THE POWER CABLE. Using the power cable will lead to
pump failure which will not be covered by warranty, all costs will be borne by the installer.
3) Install the pump UPRIGHT in the tank. The length of the pump must be vertical, it must
not be on an angle off vertical, it must not be horizontal.

Page 6 Ascento Group Australia P: 1800 807 604 E: [email protected]m.au
4) DO NOT install it in such a manner that it would require a person to get inside the tank to
remove/repair it.
5) You MUST use 25mm or larger POLY or PVC pipe connected to the discharge of the pump.
DO NOT CONNECT COPPER or GALV PIPE or less than 25mm ID POLY/PVC PIPE to this
pump.
6) VERY IMPORTANT: Ensure that the connection to the outlet of the pump is robust and
sealed VERY well. Use 15 wraps of thread-seal tape on the male thread. DO NOT USE glue
unless you are CERTAIN that you will not drip glue inside the pump.
7) Glue or other substances dripped inside the pump voids warranty. Do NOT fit threaded
fitting to the pump then glue pipe to that fitting as glue will drip inside the pump. Glue the
fitting and allow it to dry BEFORE attaching the threaded fitting to the pump. NOTE: If the
fitting leaks, it will cause cycling of the pump, this is not warranty –this is the installer’s
responsibility.
8) Ensure that the pump will not knock against the side of the tank during start-up, or
operation or stopping.
9) No electrical appliance lasts forever - the pump must be easily accessible for repair or
servicing - if the rainwater tank is installed under eaves, or under a deck or any other
structure, ensure the pump can be easily removed.
10) For underground tanks, the installation must be designed and constructed to allow easy
access, for servicing and repairs to the pump. In the unlikely event of pump failure,
warranty does not include costs of digging up gardens and re-running electrical cables, etc.
11) If the pump has a float switch, ensure it CANNOT get stuck on the side of the tank or
under baffles or similar - warranty service does not cover this situation. FOR PUMPS WITH
FLOATS: The water level will need to be 0.6m to 1.2m high inside the tank, for the pump
to start.
12) An Isolation valve must be fitted (ball-valve or gate-valve) in the discharge pipework
13) A Barrel-Union must be fitted external of the tank to allow easy servicing of the pump,
install it after the elbow to avoid it twisting loose from the pump starting & stopping.
14) It is the INSTALLERS responsibility to check the pumps operation prior to leaving the site
CHECK ALL CONNECTIONS: Ensure all fittings and joints are watertight and airtight. Leaks
will cause the pump to cycle on & off continuously, this is not a fault of the pump.
15) All Electrical Wiring & Power Outlet & Cable protection must be in accordance with
applicable Australian Standards. We recommend a separate circuit.

Page 7 Ascento Group Australia P: 1800 807 604 E: [email protected]m.au
16) IRRIGATION USE - MANDATORY REQUIREMENTS FOR ALL INSTALLATIONS: For any
installation of pumps supplying irrigation, you must fit an 18L or larger pressure tank.
Set tank air pressure: RPS036 set air pressure to 250kPa, RPS050 set air pressure to 350kPa
17)
IMPORTANT NOTICE RE THE STOPPING FUNCTION: In some situations the pump will cycle
a few times after each use. THIS IS NOT A WARRANTY FAULT, it is a normal function of
the internal pump controller releasing excess pressure when there is some “bounce” or
“give” in the pipework or connected fixtures – it is often caused by toilet cisterns or a
short discharge pipe or flex in pipes. It is not a fault with the pump. If the owner does not
want this to occur, install a 2L or larger Pressure Tank, set the tank air pressure: RPS036
set air pressure to 250kPa, RPS050 set air pressure to 350kPa.
18) IF THE PUMP BLEEDS OUT OF THE TOP After startup, the pump may bleed water out of the
top of the pump –this is NOT a fault, it is the normal operation of the pump.
19) Some air can be pumped when the tank is low in water –this is not a fault it is normal
operation.
20) NO RCD/SAFETY SWITCH? DO NOT INSTALL PUMPS!!
FURTHER INFORMATION FOR THE INSTALLER
21) Try to minimise the amount of bends in the delivery pipe. Pipes of insufficient diameter connected to the
pump will severely restrict the performance of the pump, cause the pump to use more electricity, and
may cause the pump to cycle on/off frequently, this is not covered by warranty as it is caused by the
installer. If the user requires the best possible pressure from the pump, the recommendation is for the
delivery pipe to be 25mm ID for the majority of the pipeline.
22) IRRIGATION USE TANK PRESSURE SETTING: Air pressure must be set at 70% of maximum pump pressure
–set the tank air pressure: RPS036 set air pressure to 250kPa, RPS050 set air pressure to 350kPa. The
Pressure Tank is simply fitted to the discharge pipework with a “tee”, anywhere between the pump and
the first point of discharge.
23) During installing or servicing disconnect the pump from the power supply.
24) Ball-valves or gate-valves must be fitted on the discharge, and the Town-water backup supply where
fitted. An additional Check-valve must be fitted outside of the tank (not on the pump) where it is used
with a Town-water backup system, but only if the Town-Water backup system does not have a built-in
check-valve on the Rainwater connection. This instruction is a condition of warranty; all warranty is void if
this instruction is not followed. The pump must be installed to comply with applicable Plumbing
Regulations.
25) Do not remove the base off the pump as this will then cause it to take in solids or sludge which will lead
to reduced performance and ultimately, failure, which is not covered by the warranty. This pump is not to
be used as your sole water supply. For critical applications where loss of water supply could cause serious
consequences, use a DUAL PUMP System so you have a back up water supply or use a TOWN-WATER
BACK-UP SYSTEM. This pump is not designed for Fire Fighting purposes.
26) IMPORTANT: This pump MUST NOT be installed in any manner that if it were to fail that it would cause
damage or loss to property or persons. It MUST be installed in a well-ventilated and drained area.
27) DO NOT lower or lift the pump using the power cable –use nylon rope to lower or lift the pump in and
out of the tank.

Page 8 Ascento Group Australia P: 1800 807 604 E: [email protected]m.au
28) The pump will operate fully automatically, it will start on demand when pressure drops below approx
200kPa, and will stop when demand ceases, after pumping for some minutes to regain full pressure. It
may turn on & off a few times, refer point 16
29) ELECTRICAL SUPPLY: (a) Plugging into existing outlets that have other appliances connected may cause
low voltage supply to the motor, causing the circuit-breaker to trip, tripping of motor overload, or burnt
out motor, which will not be covered by the Warranty. RECCOMENDATION: a dedicated electrical circuit
with a combination circuit breaker & safety switch be installed for ALL pump types. This is important in
order to prevent inconvenience to the resident, is an additional safety precaution, and also helps to avoid
un-necessary call-outs after hours and on weekends. (b) Surge Protection - We recommend that a surge
protector is used to protect the electronics of this pump, as damage due to power surges is not covered
by the Warranty. (c) The Power Outlet must be in easy reach for the owner to access, and must be in a
sheltered area to prevent the plug and power outlet getting wet from rain or snow or garden irrigation
or the roof gutters overflowing, etc. VOLTAGE of power supply must match the voltage of the pump,
230-240Volt from MAINS supply only. Do not use with generator power. If you only have generator
power, you will need to have the pump removed and replaced with a different type with a Pressure Tank
and Switch, at additional cost. The Pressure Controller will be damaged by the voltage fluctuations caused
by generators.
30) LEAK PROTECTION FUNCTION; If the pump starts and stops more than 7 times in 2 minutes, it will stop
operation automatically. Frequent starting and stopping usually indicates something is leaking.
Investigate the cause and rectify the leak. Toilet Cisterns are often the problem, turn their stop-cock off
to eliminate this possibility. After the cause is fixed, turn the power off to the pump, and then back on
again, to reset the automatic controls. If the cause cannot be ascertained, fit a Pressure Tank somewhere
between the pump and the first point of discharge –suggested pressure setting for the tank is 150kPa.
31) NO WATER FUNCTION: The pump will stop automatically if the tank is empty/nearly empty. VERSION
WITHOUT FLOAT SWITCH: It will then restart to check for water after some minutes, then off for 1 hour
and restart again, then off for 5 hours then restart again, if there is no water it then is off for 24 hours,
and will restart automatically every 24hours, indefinitely. If there is no rain expected for some days, turn
the power off at the power outlet to save power. VERSION WITH FLOAT SWITCH: when the water level
drops below about half of the height of the pump it will turn off the power to the pump, the pump will
not restart until the tank fills up again.
32) WARNING: these pumps are not designed for and must not be installed in locations classified as
hazardous.
33) THE FOLLOWING MAY CAUSE SEVERE DAMAGE TO THE PUMP AND WILL VOID WARRANTY; (a) Using an
extension cord to power the pump. (b) Cutting the earth pin off the plug or using an adapter fitting or
double adapter. (c) Working on the pump while connected to the power supply. (d) Removing motor
housing, or dissembling the pump housing, except by a qualified technician (e) Pumping chemicals or
corrosive liquids or flammable liquids or dirty water or waste water or contaminated water. (g) Pumping
hot liquids (Exceeding 35°C) (h) Using a generator for power supply –see 27
34) 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 for possible causes –refer to trouble-shooting.
35) IMPORTANT NOTES (a) Do not switch the pump on and off frequently, as this will cause damage to the
electronics and void warranty. (b) If there is insufficient water, the motor will stop. (c) 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.
All warranty is void if these instructions are not heeded and no liability can be accepted in the case of damage
or loss caused by failing to comply with all the instructions.

DANGER!!!
Keep the pump equipment protected from interference by children, infirm persons,
incompetent persons, pets and wildlife.
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 to pump dirty water, or to pump
liquids other than clean water.
WARNING!!!
It must never be used in bodies of water used for swimming or bathing or in
animal drinking containers.
PUMP CONTROLLER FUNCTION AND OPERATION:
The pump controller inside 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
b) Do not operate on domestic generator power supply as this may damage the electronics
c) Points d) to h) do not apply to pumps WITH FLOAT SWITCH –the float turns the power OFF to the pump when water level is
low, it will not turn back ON until the tank fills up again.
d) The pump controller will stop the pump if there is no water in it
e) It then rechecks for water several times –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 will do no harm to the pump. Air and water mix
may come through the pipes when this happens, this is not a warranty fault.
f) It will check for water after some minutes, then off for 1 hour and restart again, then off for 5 hours then restart again, if
there is no water it then is off for 24 hours, and will restart automatically every 24hours, indefinitely.
g) If it happens to do this in the middle of the night it can be annoying to the residents. In the early morning, turn it off & on
again after 1 minute and it will reset itself so it does the checking in daylight hours.
h) You can reset the function back to the beginning anytime by turning the power off, and on again after 1 minute.
i) If it is some days before it is expected to rain, turn off the power to the pump, at the power outlet, to save power.
j) When the pump re-starts after a run-dry event, some air might come through the pipes, this should do no harm, and is not
a warranty fault.
TROUBLESHOOTING CHECKLIST
Check the following before requesting service or repair. A call out fee and labour cost may apply to field services.
PROBLEMS & POSSIBLE CAUSES;
1.Pump Operates When Water Tank Is Empty: this is either the normal re-start function of the pump, or due to an airlock, or
some debris inside the pump > simple solution is to turn the power off to the pump, and turn it back on when rain fills the tank.
NOTICE: tank level indicators are not always accurate!! Check inside the tank to be sure of the water level.
2. Pump does not run or motor runs for a short time, then stops
1. Circuit breaker or Safety Switch is off or fuse has blown > in a SAFE manner investigate why this has occurred, by process of
elimination > do not assume it is the pump > if you cannot do this safely, have a licenced Electrician check and rectify it.
2. Water level in the tank is too low > Top up or use alternative supply > or turn pump off until the tank fills
3. Electrical components have been flooded > It is likely that the pump will need to be replaced > in a SAFE manner investigate why
this has occurred, by process of elimination > do not assume it is the pump > if you cannot do this safely, have a licenced Electrician
check and rectify it.
4. Pump plug is not connected properly, or has been flooded or wet > Isolate power at main switch, remove plug & allow to dry. If
the problem continues, contact a licenced electrician to check the cause.

Page 10 Ascento Group Australia P: 1800 807 604 E: [email protected]m.au
5. Pump has an air-lock >Start and stop several times by turning the power off, wait 30 seconds, and turn on again, repeat if
necessary.
6. If all of the above are OK, the pump might have overheated and triggered the thermal overload switch > Turn it off and wait 30
minutes for it to cool down and turn it on again > If the pump does not operate normally, investigate why, it might be blocked with
debris, > flush clean and re-assemble.
3. Pump runs but does not deliver water or only a small amount of water
1. Water filters on the discharge (if fitted) are clogged > check / clean /replace the cartridges
2. Check valve is installed backwards, arrow on valve should point in direction of flow > have the installer fix this.
3. Discharge shut-off valve/ball-valve / gate-valve may be closed > open the valve.
4. Impeller or volute openings are fully or partially clogged or it might be blocked with debris > disconnect from the power supply,
and if you are competent to do so, disassemble the pump and clean. If not, have a pump technician do it for you.
5. Pump is air-locked > Start and stop several times by turning it on and off with 20 seconds between. If this does not work, see
below regarding re-priming the pump
6. Vertical pumping distance is too high - Reduce distance or upgrade to a larger pump.
7. Tank too low water level > Check the water level by looking inside the tank (Tank level indicators can be wrong)
4. Pump runs and does not stop or runs when no taps are in use
1. In most cases this situation it is due to a leak in pipework or leaking toilet cisterns or an underground pipe leak (wet soil, muddy,
grass growing well!) > it is not a pump fault > ascertain by process of elimination what is leaking > turn off the isolation valve on the
discharge pipework > does the pump stop = the leak is further down the line > if not then check toilets etc > the only sure way to
check toilet cisterns is to turn them off at the stopcock which is usually under the cistern as most of them will not run into the pan.
2. The pump has come loose off the pipe inside the tank > look inside the tank with a torch to check this > if the water is above the
pump you will need to lower the water level so you can check this properly > if there is water leaking inside the tank have the
original installer return and rectify this, it is not covered by the pump warranty as it is an installation issue.
3. There is a leak in the pipework inside the tank > reduce the water level in the tank until you can see the top of the pump, open a
tap to a slow dribble so the pump starts, then remove the leaf-trap off the tank and use a bright torch to inspect the pipework inside
the tank to see if it is leaking –even a slight leak will cause the pump to cycle on/off/on/off > if there is water leaking inside the tank
have the original installer return and rectify this, it is not covered by the pump warranty as it is an installation issue.
5. Pump not pumping properly
1. Too high head or pump under specified > Check specifications.
2. Too low water level > Check the water level in the tank, tank level indicators are not always accurate
3. If a check valve has been installed directly on the discharge of the pump, this will cause the pump controller to malfunction >
Move the check valve to outside of the tank.
6. Safety Switch (RCD) or Circuit Breaker trips when the pump starts
1. Circuit is overloaded with too many appliances connected to it > contact a licenced electrician to install additional circuit
2. Power plug is wet > refer 2.3
3. If none of the above, the Motor may be defective > have it checked by a qualified technician
If you have checked all the above trouble shooting points and fail to rectify the problem, have the pump checked by
an experienced pump technician.
