INSTALLATION GUIDE : TICK AS COMPLETED AND LEAVE THIS FOR THE OWNER
CONDITION OF WARRANTY : this checklist must be completed and left for the owner.
Tick the boxes on the left side as each step is completed;
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.
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 warranty
fault with the pump.
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
must be installed to prevent debris from entering the tank, or a filter screen through which all the incoming
water passes before entering the tank. NO WARRANTY if the pipe is less than 25mm INTERNAL DIAMETER.
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 baffles inside the tank.
Step 3
Attach Rainwater supply to the RM4000-3 Valve as shown in the diagram.
Step 4
Connect Discharge pipework to the RM4000-3 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 RM4000-3 valve assembly through the PRV (pressure
Reduction Valve) ensuring that flow is with the direction 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!!!
Ensure mains is connected to the correct side, as labelled.
IMPORTANT: if installing close to a wall or other fixture, use barrel-union connections to
allow removal if ever required.
IMPORTANT:
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 RM4000-3
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
