Installation Considerations
• For best results, Hansgrohe recommends that
this unit be installed by a licensed, professional
plumber.
• Please read over these instructions thoroughly
before beginning installation. Make sure that
you have all tools and supplies needed to
complete the installation.
• This pressure balance valve is for use with shower
heads rated at 1.1 GPM (4.2 L/min) or higher.
• #26478xx1 only: this showerhead is
intended for use with an automatically
compensating valve rated at 1.9 GPM
(7.2 L/min) or less.
• To prevent scald injury, the maximum output
temperature of the shower mixing valve must be
no higher than 120°F (49°C). In Massachusetts,
the maximum output temperature can be no
higher than 112° F (44°C).
• The pressure balance trim with diverter is
suitable for a two-function installation, such as a
showerhead and tub spout, or showerhead and
handshower.

Do not use this trim in a one-function
installation.
Do not use a diverter tub spout.
Do not install a shut-off device on
either outlet of this valve. Use of such
a device can defeat the ability of the
valve to balance the hot and cold water
pressures.
• Keep this booklet and the receipt (or other proof
of date and place of purchase) for this product in
a safe place. The receipt is required should it be
necessary to request warranty parts.
The rotational limit stop (see page 23)
Adjust the rotational limit stop if:
• The maximum output temperature is greater
than 120°F (49°C) or that permitted by local
plumbing code
• The temperature of the incoming hot or cold
water supply changes seasonally, or if changes
are made to the water heater.
