Technical Data

Functioning Principle

The Grohsafe pressure balance valve is a
safety mixer designed to compensate for
fluctuations in the water supply pressures,
which would otherwise affect the mixed
water temperature.

This product is supplied with connectors to fit
ø 15mm pipework. Connection should be hot

left, cold right as viewed from the operating
position. The product is preassembled, as
standard, with the outlet up.
For bottom outlet installation refer to
page 7 and 10.

Plumbing Systems

Suitable for use with multi-point gas water
heaters or combination boilers with a modu­lating hot water output. To maintain suf ficient
hot water output ensure the combination
boiler temperature setting is on high. Also
suitable for mains pressure unvented and
instantaneous thermal hot water storage
systems.

Not suitable for instantaneous hot water
displacement heaters or gravity-fed plum­bing systems with an open vented hot water
cylinder and cold water storage cistern.

Supply Pipework

Ensure the supply pipework is thoroughly
flushed before installing the mixing valve.
GROHE recommends installing isolating
valves upstream of the mixing valve for
servicing purposes, and in-line strainers to
prevent the ingress of water borne debris.

New Water Regulations

This GROHE-product is designed to comply
with the current Water Bylaw 17 and the new
Water Regulations covering back-flow pre­vention. It must be installed in accordance
with local authority bye-laws. Incorrect instal­lation could contravene bye-law installation
requirements.
