IMPORTANT INSTALLATION & WARRANTY CONDITIONS
1.
The mains supply must not exceed 500kPa refer AS/NZS 3500.1
2. 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.
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.
4. DO NOT install it in such a manner that it would require a person to get inside the tank to remove/repair it. Install the valve-set external of the
tank.
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
13/18/20mm POLY/PVC PIPE to this pump. Do not install the valve-set directly onto the pump as this will cause malfunction.
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. 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 250mm to 800mm high inside the tank, for the pump to start.
12. Isolation valves must be fitted (ball-valve or gate-valve) on Mains supply and discharge.
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.
16. It is recommended to install a pressure tank (approximately 2L capacity) on the discharge pipework, anywhere between the pump and the first
fixture, closer to the pump is preferred.
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.
18. Some air can be pumped when the tank is low in water
– this is not a fault it is normal operation.
19. WARNING:
NO RCD/SAFETY SWITCH IN THE POWER CIRCUIT? DO
NOT
INSTALL PUMPS!
HOW THE SYSTEM WORKS
1.
When the Rainwater tank is empty/nearly empty, the pump controller will sense there is insufficient water and turn the pump off (or for submers-
ible pump with float, the float switch will turn the pump off)
2.
When this happens, the submersible pump shuts down.
3.
Mains water (Town-Water) will flow freely so you always have water when the Rainwater is “off”.
4. Some pressure difference may be noticed between the different water supplies – this is normal, it is not a fault with the system – the mains water
from the RM5000-3 Valve-set may be at lower pressure than the rainwater supply.
5.
Occasionally toilet cisterns might make some strange noises due to some air coming through the pipes, this will do no harm, and is a normal part
of the automatic operation.
6.
The pump will attempt to re-start several times over the period of a few minutes. The pump might “crackle & gurgle” a bit due to air in it, as it
tries to restart, this is not a fault, it is normal.
7.
If the pump cannot get enough water it will then stay off for 24 hours, then repeat the same process every 24 hours to check if there is water in
the tank.
8.
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.
9.
6 to 8 are not applicable for a submersible pump with float switch, it will stay off until the tank fills again.If there is no rain for a long time, and the
tank is dry, it is best to turn the pump off, at the power outlet.
10. Sometimes the pump may try to start when the tank is empty/nearly empty, this is not a warranty fault it is due to some water residue inside the
pump. Simply turn the pump off at the power outlet until the tank refills with rainwater.
11. A “First-flush-diverter” or similar device must be installed to prevent debris from entering the tank, or a filter screen through which all the incom-
ing water passes before entering the tank.
12. Sometimes even after rain, there might be an air-pocket in the pump and it does not restart. This is NOT a warranty fault!! Simply turn the pump
off at the power outlet, and back on after 20 seconds, repeat until water flows normally. If this does not work, you may need to either: Turn the
mains off using the MAINS ISOLATION VALVE (see front page) and restart the pump.
13. Before assuming there is a fault with the pump operation, check the water level in the tank, the pump may not operate unless there is 600 to
1200mm of water depth in the tank, note that tank-level indicators are not always reliable (water level required is dependant on the type of pump
& the installation, also see the important note below)
14. IMPORTANT! FOR PUMPS WITH FLOATS:
The water level will need to be 250mm to 800mm high inside the tank, for the pump to start.
