Installation

Site Selection for the 3P Controller Unit

We recommend installation be carried out by a qualified electrician.

The Control Unit and Solenoid Valve must be mounted indoors in a dry place. Do not install in a

location subject to freezing temperatures.

It can be wall mounted using the supplied fittings.

NOTE: It is not a waterproof unit. DO NOT install in a tank turret.

3P strongly recommends wiring the unit on a dedicated circuit, protected by a 10A Type C circuit

protective device, in accordance with current best practice and regulatory requirements as defined by

BS 7671, current IEE wiring regulations, and Part P of Building Regulations (where applicable). If in any

doubt consult a qualified electrician.

There are a wide variety of pumps supplied in the UK rainwater market, some with 2 pin "Schuko", and

some with 3 pin UK plugs. A 2 pin "Schuko" plug can plug directly into the plug socket on the face of

the unit. If your pump has a 3 pin UK plug there are two options available.

•

Change the pump's plug to a 2 pin Schuko plug (one is supplied with this kit).

•

Use an earthed 2 pin Schuko to 3 pin UK socket adapter to plug into the Control Unit's pump

socket (not supplied).

SAFETY NOTE – European style Schuko plugs are not protected with a fuse, therefore it is vital the

controller is installed on a 10A fused outlet to protect both the pump and controller.

If in any doubt you MUST consult a qualified electrician.

The 3P Tundish and bracket assembly

The 3P Tundish acts as a Type AA air gap to comply with BS EN 13076: Devices to prevent pollution by

backflow of potable water. The 3P Tundish itself and its' ½" feed nozzle are both freely rotatable in the

wall mounting bracket.

Install the 3P Tundish so that the potable water feed can gravity flow freely into the tank. Check the

rate of delivery of potable water does not exceed the capacity of the connected hose/pipework to

reach the tank at your site, without backing up. This is part of the Commissioning of your rainwater

harvesting system installation process.

The 3P Tundish outlet to the tank (Nominal OD 47mm, ID 39mm) can be connected using 2" hose or

with a 50mm MDPE Compression fitting, usually reducing to 32mm minimum, or using Waste Pipe at

50mm.
