1. Operating instructions for the user and the qualied installer
Description
The EHS 15-150 unvented (pressur-
ized) wall-mounted water heater can
heat potable water up to about:
EHS 15-150 = 75°C to suit demand
and supply a number of draw-off
points. Thewatercontentisautomatically
heated to the preset temperature.
The device is adjusted at the works to
75°C.

Important notes:
High temperatures present
the risk of scalding.
– Arrange to have the wall-mounted
water heater and the safety valve
or safety group checked regularly
by a qualified installer.
– Check the fittings regularly; clean
limescale off outlets using
conventional commercial descaling
products.
The device is under water
pressure. During heating,
water will drip from the safety valve
for reasons of safety; if dripping
continues after heating-up has
concluded, contact your installer.
Risk of freezing
The device is protected against freez-
ing at every temperature setting,
but not the safety valve or the safety
group and the water pipe.
Temperature adjustment
EHS 15 - 150
The temperature adjustment may be
altered by the user directly at the
temperature knob.
Care
A damp cloth is all that is needed for
care and cleaning the outer housing.
Do not use any foaming or caustic
cleaning agents.
Instructions for use and installation
Keep these instructions in a
safe place, and give them to
the new owner if you move house; if
maintanace or repair work is required,
let the qualified installer have them
for reference.
