PRODUCT OVERVIEW / APPLICATION
The Vada Rain2Main is designed to select between stored rainwater
(when available) and mains supply water, and send this water to
your toilet cistern, washing machine, garden and other non-potable
household water applications. It features automatic pump control to
minimise the use of electricity while saving water.
When your tank is empty, the Rain2Main seamlessly switches to
mains water supply so that there is no interruption of water to your
toilet cistern or washing machine.
Do not use the Rain2Main for liquids other than clean water.

INSTALLATION
Freezing conditions will damage the unit, as water expands as it
freezes. Ensure that the Rain2Main is located so that it is not prone
to freezing, or ensure that the product is disconnected and dried of
water during cold conditions.
Rain2Main is electrically connected. Ensure that it is isolated from
electrical supply during installation and any subsequent service
work.
Do not install or operate Rain2Main in an explosive environment or
near combustible matter.
Brace inlet and outlet connections while fitting Rain2Main. Any
movement of connections may disturb internal seals and cause
leakage.
PREPARATION FOR INSTALLATION
Read these instructions first. Inspect Rain2Main for shipping damage.
Report any damage to your Reece store of purchase.
If the incoming mains pressure to your property is greater than
the specified 1000 kPa, please fit a pressure reduction valve
of appropriate capacity upstream of Rain2Main. This pressure
reduction valve must bring the pressure to below the rated value
of 1000 kPa. A recommended pressure is 500-750 kPa. Fitting
this type of device to your entire household will extend the life of
other appliances such as washing machines, hot water service and
dishwashers.
Ensure installation is in accordance with AS/NZS 3500.1 - Plumbing
and Drainage - Water Services.
Fittings and Accessories
Ensure that you have all required fittings and accessories prior to
installing Rain2Main.

INSTALLATION RECOMMENDATIONS
1. The Vada Rain2Main comes with 2 mesh inline filters. These filters should be correctly inserted on the mains water input and pump input of the
Rain2Main.
2. The recommended height of the tank outlet from the base of the tank be set at 100mm.
3. A recommended minimum distance of 100mm of straight pipe at the Rain2Main mains water inlet.
4. Clean water is essential for the reliable operation of your Rain2Main system. We recommend the installation of first flush diverters and leaf guards
on your water collection system.
Mounting
The pump and Rain2Main must be mounted on a solid, level, vibration-
free surface. The Rain2Main can be mounted in one of two ways:
1. Mount directly to the top of the pump with surface accessory kit.
2. Mount remote from the pump with wall bracket.

INSTALLATION
Connecting the Rain2Main to the Pump Using the Union Kit (Where Supplied)
1. Wrap a sufficient amount of thread seal tape around both ends of the 1” Nipple.
2. Connect one end of the nipple into the pump discharge, threading it until it is watertight. (DO NOT OVERTIGHTEN)
3. Connect the 1” Female end of the complete barrel union onto the protruding end of the 1” Nipple until it is watertight (DO NOT OVERTIGHTEN)
4. Wrap a reasonable amount of thread seal tape around the 1” end of the union nipple. Thread it into the base of the Rain2Main until watertight
(DO NOT OVERTIGHTEN). If you are unable to screw the Rain2Main on top due to space limitations, unscrew the barrel union nut releasing the
nipple from the union, then thread the nipple into the Rain2Main (Make sure the Union nut remains on the nipple). Rejoin the union to complete
the connection.
Mains Inlet Connection
Rain2Main has a 1” BSP Female fitting to connect the incoming mains supply water. This end is marked with an arrow pointing into the unit
(showing water flow direction). Brace this fitting to prevent movement while connecting to the mains supply. Any movement of this fitting may
disturb internal seals and cause leakage.
Water Outlet Connection
Rain2Main has a 1” BSP Female fitting to connect to household plumbing for uses such as filling toilet cisterns, the washing machine, and garden
taps. This end is marked with an arrow pointing out of the unit (showing water flow direction). Brace this fitting to prevent movement while
connecting. Any movement of this fitting may disturb internal seals and cause leakage.
Pipe Marking
In accordance with AS/NZS 3500.1:2003, pipes and outlets connected to Rain2Main must be marked as follows:
Outlets that are connected to your Rain2Main must be marked with the wording “RAINWATER”. The piping system connected to Rain2Main must
be clearly marked at 1m spacings with the wording “RAINWATER”
Rain2Main Electrical Connection
To avoid dangerous or fatal electrical shock, turn OFF power to the Rain2Main before working on any electrical connections. The supply voltage for
the Rain2Main must be within the stated parameters.
If the power supply cord or pump interconnection cord is damaged, it must be replaced by a qualified person or return to place of purchase in
order to avoid hazard.
Before connecting Rain2Main to an electrical power supply, connect the pump to the Rain2Main using the provided IEC appliance connectors on
the end of the interconnection cords. Ensuring there are no traces of water on the connectors, push them firmly into each other to ensure splash
proof protection. This connection should only be separated for servicing purposes, and only after the power supply of the Rain2Main is removed
either through an isolation switch or by unplugging.
Rain2Main is supplied with a standard Australian 10A plug and cord, and connection to the power supply is a matter of inserting the plug into the
suitable socket outlet. If local authorities require the Rain2Main and pump to be hard wired, the electrical connection must be done by a qualified
electrician with pump knowledge according to the National Wiring rules (AS/NZS 3000) and/or any local council requirements.
We recommend to connect Rain2Main to a socket outlet protected by a Residual Current Device - RCD (Also known as an Earth Leakage Circuit
Breaker – ELCB) with a rated tripping current not exceeding 30mA. Contact a qualified electrician if you cannot verify that the socket outlet is
protected by RCD. RCD tripping indicates an electrical problem. If the RCD trips and will not reset have a qualified electrician inspect and repair
electrical system.
Do not apply power to the system until the pump has been primed and the water level in the tank is above pump suction inlet. Refer to pump manual
for further installation details.

Operation
Commissioning
Put a small amount of water in the tank (just above the level of the pump inlet). Prime the pump if surface mounted. Turn power to the rain2main
on. Open a tap on the outlet side of the Rain2Main (or have someone flush the toilet). The pump will start. Turn off the tap, and the pump will stop
(after a run-on period of 15 seconds). Temporarily close the valve between the tank and pump inlet, or drain the tank to below the pump inlet. This
indicates to the Rain2Main that there is no water in the tank, and it will switch to mains supply operation after 5 failed attempts to draw water from
the tank. Again, open the tap or flush the toilet. Mains supply water will fill the cistern. Close the tap, open the tank valve and restart the Rain2main.
If there are any variations to these outcomes, please see the troubleshooting section.
VADA - Rain2Main Automatic Rainwater Controller
MAINS SUPPLY MODE
Rain2Main has a mechanism to prevent the pump from running with no water. If the tank is empty or there is a blockage or partial blockage
somewhere in the system the following process will occur:
1. If Rain2Main is supplying water and is operating normally, it will activate the pump to supply rain water.
2. If the Waterswitch detects no flow of rain water from the tank after approx 30 seconds of pump operation it will shut the pump off and revert to mains
water supply.
3. Mains water will then be supplied for approx 30 seconds after which the Waterswitch will revert back to the pump to check for rain water supply.
4. The pump will then operate for approx 20 seconds during which time the Waterswitch will be checking for rain water flow from the pump. During this
period the Waterswitch will also allow 2 five second bursts of mains water to flow through the system to keep water flowing to thesource of demand.
5. If after this 20 second period the Waterswitch detects no flow of rain water from the pump it will then lock the pump out of operation for a period of
24 hours. During this lock out period only mains water will be supplied.
7. Automatic Lockout Reset Feature
Event Reset Time
1st lockout 24 hours
2nd lockout 160 hours (Rain2Main will check for mains water every week following, until water is available in the tank)
This feature can be over ridden by switching the unit off for 10 seconds.
General Operation
Your Rain2Main operates entirely automatically without intervention. If electrical supply is cut in your neighbourhood, Rain2Main will automatically
revert to mains supply water, as there is no power to drive the pump. When power resumes, Rain2Main will continue to operate normally.
If town supply water is shut off in your area, Rain2Main might not be able to detect water demand in the household (e.g. if the toilet cistern needs
refilling). By pressing the manual override button, you can override normal control and start the pump to supply water out of the rain water tank.
SERVICE AND MAINTENANCE
Rain2Main is a warm, dry environment for hibernating insects. These can cause electrical malfunction. Ensure that your property is vermin free.
Rain2Main is electrically connected. Ensure that it is isolated from electrical supply during installation and any subsequent service work.
Rain2Main should only be serviced by a Pentair Water service agent.
Rain2Main Service To reset from ‘loss of prime’ mode:
Before removing Rain2Main for service: a) Turn off power for 10 seconds
1. Switch off power to Rain2Main before proceeding. b) Turn power supply back on
2. Close shut off valves at inlet, outlet and water tank gate valve. c) Reprime the pump. Check for blockages in suction line.
3. Carefully release all pressure from the pump and piping system.
4. Never tighten or loosen fittings while the pump is operating. Rain2Main should resume normal operation.
6. The LED onthe Waterswitch will flash red during this period to indicate that the tank water is not available.
