Spillover Level

Hose Retaining Ring

25 mm minimum

The supplied hose retaining ring should meet the majority of user requirements for shower installations with flexible outlet fittings. However, there will be occasions when the hose retaining ring will not provide a suitable solution. In these instances an outlet double checkvalve must be fitted. This will increase the required supply pressure typically by 0.1 bar.

Double checkvalves, fitted in the inlet supply to the appliance, cause a pressure build-up, which could exceed the maximum static inlet pressure for the appliance.

16.Avoid layouts where the shower hose will be sharply kinked. This may reduce the life of the hose.
