Technical data

• Flow pressure min 7.25 psi / recommended 14.5 – 72.5 psi
• Operating pressure

max. 145 psi

• Test pressure

232 psi

If static pressure exceeds 72.5 psi, a pressure-reducing valve 
must be fitted.
Avoid major pressure differences between cold and hot water 
supply.
• Flow rate at 43.5 psi  flow pressure:

Spout

approx. 26 l/min or 6.9 gpm/60psi

Shower

approx. 8 l/min or 2.5 gpm/60psi

• Temperature:

Hot water supply

max. 176 °F

Recommended

(energy economy) 140 °F

Notes

• Installation of backflow protection must comply with local 

codes and regulations.

• An access panel must be provided for access to diverting 

unit and hose connections.

• Major pressure differences between cold and hot water 

supply should be avoided.

Note the installation position of hose (C).

Connection

1. Connect enclosed hoses (E) to the supply lines,

see Fig. [9].

2. Fit hoses (E) to pipes (D).

Open cold and hot water supply and check connections 
for leakage.

Operation

- Lever (I)

,

see fold-out page III, Fig. [10].

- Diverter (K)

Pulling lever (I) releases the water supply.
Water will emerge from the bath inlet first.
Pull diverter knob

= flow is diverted from bath inlet to 

shower outlet

Press diverter knob

= flow is diverted from shower 

outlet to bath inlet

Flow is diverted automatically from shower outlet to bath inlet 
when the fitting is closed.

Maintenance

Inspect and clean all parts, replace as necessary and lubricate 
with special grease.

Shut off cold and hot water supply.

I. Cartridge

, see fold-out page III, Fig. [11].

Assemble in reverse order.

When installing the cartridge, ensure that the seals are 
correctly seated.

Tighten the screws evenly and alternately.

II. Shower hose and filter

, see fold-out page III, Fig. [12]. 

Secure the shower hose against slipping down again.
Assemble in reverse order.

III.Diverter

, see fold-out page III, Fig. [13].

Assemble in reverse order.
When screwing in (left-hand thread) the sleeve (A), make sure 
that the internal groove aligns with the position of the set
