INSTALLATION & CHECKLIST
All installations must be in accordance with AS/NZS 3500.1
Maximum Pressure - A pressure reduction valve must be fitted if mains supply exceeds 500kPa
Maximum Temperature – for Coldwater use only.
INSTALLATION GUIDE: TICK AS COMPLETED AND LEAVE THIS FOR THE OWNER
* CONDITION OF WARRANTY: THIS CHECKLIST MUST BE COMPELTED AND LEFT FOR THE OWNER
STEP 1:
Install Submersible pump into the tank using PVC or POLY 25mm (minimum ID size) outlet pipework attached. Do not use the electrical cable to
lower the pump into the tank, use nylon rope or similar.
NO WARRANTY if the pipe is less than 25mm INTERNAL DIAMETER.
WARNING!
Ensure a very strong connection of pipe to the Pump Outlet INSIDE the tank – use 15 wraps of threadseal tape on the MI fitting that
attaches to the pump – if insufficient threadseal is used the pump may come loose and will then cycle on/off/on/off continually – this is not a war-
ranty fault with the pump - it is the installers responsibilty to rectify this if it occurs. Install the Valve-set external of the rainwater tank.
NOTE!
DO NOT use COPPER or GALV PIPE directly connected to this pump, warranty void if used.
IMPORTANT:
use a barrel union connection external of the tank, after an elbow to avoid the pump “start / stop twist” causing it to come undone,
to allow easy removal of the pump for servicing, if the tank is installed under eaves or other structure such as a deck, ensure that the pump can be
easily removed for servicing or repairs.
IMPORTANT! Mandatory condition of Warranty:
you MUST install a “First-flush-diverter” or similar device to prevent debris from entering the tank,
or a filter screen through which all the incoming water passes before entering the tank.
STEP 2:
IF THE PUMP HAS A FLOAT SWITCH:
ensure it can move freely and wont get stuck against the side of the rainwater tank, or caught under struts or
baffles inside the tank.
STEP 3:
Attach Rainwater supply to the Valve, external of the tank, as shown in the diagram.
STEP 4:
Connect Discharge pipework to the RM1500-2 Valve and connect to the house supply. It is recommended to use flexible, not rigid pipework, to help
avoid vibrations from the pump transmitting to the house.
STEP 5:
Mains supply is to be connected to the RM1500-2 valve assembly through the PRV (pressure Reduction Valve) ensuring that flow is with the direc-
tion indicated on the valves. DO NOT remove or adjust the PRV as it is integral to the function of the system – even if there is a PRV/PLV installed
on the house supply already – do not remove this one – all warranty is voided if so and the system will not function correctly.
IMPORTANT:
1.
Ensure mains is connected to the correct side, as labelled.
2. If installing close to a wall or other fixture, use barrel-union connections to allow removal if ever required.
3. MAXIMUM PRESSURE - A pressure reduction valve must be fitted if mains supply exceeds 500kPa
STEP 6:
If garden use of rainwater is required, then this could be taken off between the pump and RM3550 valve assembly to avoid Townwater use on the
garden – ensure compliance with Government, Local Government and Plumbing Regulations first.
Important!
Work on the mains supply must be in accordance with the relevant plumbing code or standard, and performed by a licensed plumber.
STEP 7:
After all pipe work is connected, check for leaks and rectify according to Plumbing regulations.
STEP 8:
Plug the pump’s power lead into the power outlet provided, which must be installed by a licensed Electrician according to Electrical Regulations.
IMPORTANT CONDITION OF WARRANTY
1. The power outlet used for the pump must be protected by an RCD (Safety Switch) - do not install the pumps without this protection. We
recommend a separate circuit for the pump.
2. The Power Outlet must be in easy reach for the resident - it must not be up above the rainwater tank where a ladder is required to reach it.
STEP 9:
Test the system by filling the tank with some town-water if it hasn’t rained, then open connected garden taps, flush toilets etc. If the pump fails to
operate, re-boot it and check if the float is in the UP position. Remember that pumps with a FLOAT SWITCH will need 250 to 800mm of water in
the tank, to keep the pump on.
STEP 10:
If you experience any problems, refer to the troubleshooting guide first, before calling for warranty service. A call-out fee will apply for all field
service work if it is found not to be a Warranty problem.
