 The actuator tube should be tilting down 
to the left (brass end lowest). 

note:

 the 

chain is not connected at this stage.

Rotate the tail of the valve with a wrench 
until the spirit level indicates that the 
valve is 

absolutely level

. The actuator 

tube is actually angled 26º from horizontal 
at this point.

  Using the 4mm Allen key supplied, fit the 

discharge assembly (referring to Diagram 
5 for the direction).

  Remove and discard the protective cap 

from the discharge assembly, before 
adjusting closing level, testing and use.

  The length of this chain determines the 

opening water level and the position of 
the float on the chain determines the 
closing level and the delay.

closing Water level (tWl)

 When the 

actuator tube is held horizontal, the 
closing water level is indicated by the 
base of the closing float. Identify the 
desired maximum water level & measure 
the distance from the centre line of the 
valve; this is X.

oPening Water level (lWl)

 When the 

actuator tube is held horizontal, the 
opening water level is indicated by a line 
on the opening buoy. Identify the desired 
minimum water level & measure the 
distance from the centre line of the valve; 
this is Y.
