For 3, 4 and 6 row systems, screw the valves on to the threaded 

tees and elbows as shown. 9, 12, 15, 16 & 18 pot systems use 19mm 

threaded tees & elbows, 21 pot systems upwards use 25mm.

Place the valves as shown and connect them with blue pipe. Use the 

smaller size of jubilee clips to secure.

Use silver 16mm pipe to install the reducing tees in line with the lid 

clip and attach pieces of 4mm pipe through the slot in the lid clip.

The silver 16mm pipe runs the length of the system from the valves 

to the last pot. Fit 16mm blanks at the end of each line.

 Tank

Assemble the tank using the leaflet provided. The tank can be 

located inside or outside of the grow room. If located outside, 

depending on distance, more pipe may be required.
RAIN™ Pump
Fit the blue pipe to the RAIN™ pump and secure with a Jubilee clip. 

4 - 18 pot systems use 25mm pipe. 21 pot systems upwards use 

40mm pipe. The pump sizes are shown here.
Place the RAIN™ pump at the bottom of the tank and fit the 

25mm/40mm siphon tee as shown just underneath the lid. Put a 

piece of pipe through the hole in the tank lid and fit 2 x elbows.  

Use hose clips to secure all connections on the blue feed line. 

The drain siphon tee is 19mm and is connected in the same way  

but without clips. Black 19mm elbows and pipe are used here.
Connect the blue feed line and black drain line to the fittings on the 

header. Secure feed line with clips.
Secure the RAIN™ Brain to a wall, away from possible water contact. 

Connections to “Power” and “RAIN™ pump” are shown.
Connect the cable from the red drain pump in the header pot to the 

ALIEN

 adaptor by pushing the connector in and securing the lock 

nut. You may have a different style of adaptor than the one shown.

This should remain powered 24/7. Whenever the pump senses 

water it will engage and drain the header.
