10. FITTING THE RISER RAIL AND HANDSET 

1.  

Establish height of riser rail to suit users 

requirements (Fig 1).

2.  Remove 

caps and covers for the riser rail wall 

brackets, mark the position of the holes and drill, 

plug and screw to fit the two wall brackets

 (Fig 2).

3.  

With the handset height adjuster on the left hand 

side, fit the soap dish and then the hose retaining 

ring, onto the bottom of the rail assembly 

(Fig 3).

4.  Replace the rail assembly through the lower 

bracket and clamp. Fix the top bracket to wall 

and then loosen lower bracket and fit rail into top 

bracket ensuring the slot locates into the notch and 

retighten the lower bracket. Refit caps (Fig 4).

5.  

To fit the handset, connect one end of the double 

interlock hose to the outlet on the mixer valve, 

making sure that the sealing washer is in place 

(Fig 5).

6. 

 Screw the remaining end of the double interlock 

hose to the handset making sure the sealing 

washer is in place, then locate the handset into the 

handset height adjuster Fig 6).

NOTE: It is the conical end of the double interlock 

hose which grips into the handset height adjuster.  

The handset will not fit in the height adjuster without 

the double interlock hose attached.

TIPS

•    A piece of insulating or masking tape applied 

to the wall before marking out the fixing 

holes will help stop the drill from wandering, 

particularly on tiled surfaces.
