Safety instructions
Please follow these safety instructions closely to prevent accidents and
material losses.
Safety regulations
Installation, commissioning,
inspection, maintenance and repairs
must only be carried out by a
competent person (heating
engineer/installation contractor).
Observe all current safety
regulations as defined by DIN,
EN, DVGW, TRGI, TRF and VDE or
locally applicable standards.
See also the "Safety instructions" in
the "Vitotec technical
documentation" folder.
Before working on the equipment/
heating system, isolate the power
supply (e.g. by removing a separate
mains fuse or by means of a main
isolator) and safeguard against
unauthorised reconnection.

DHW cylinder installation and levelling
¨Install the DHW cylinder in a
room that is free from the risk of
frost and draughts. Otherwise it
must be drained when not in use
and there is a risk of frost.
Level the DHW cylinder with its
adjustable feet.
!Please note
The thermal insulation must
not be able to come into
contact with naked flames.
Exercise caution when welding
and soldering.
Note
Never extend the adjustable feet
further than 35mm of their total
length.
Connecting the earth bonding
Connect the earth bonding in
accordance with the requirements
stipulated by your local power supply
utility and current local regulations.
Fitting the cylinder temperature sensor
Insert the cylinder temperature
sensor until it bottoms out inside the
sensor well and secure with the
strain relief sleeve.
Affix the type plate on the back of the
DHW cylinder.

1. For heating water flow
temperatures above 95ºC:
Remove the cover bezels from the
heating water side pipe outlets
(bezels have l.h. threads).
2. Install the return line with an
incline and fit an air vent valve at
its highest point.

Connecting the domestic hot water side
HFor the connection on the DHW side, observe DIN1988 and DIN4753
[or local regulations].
HEquip the DHW circulation line with a circulation pump, check valve and a
time switch. Only a limited gravity operation is possible.
HConnect all pipes with detachable fittings.
HUse red brass caps to seal connections that are not required.

Connecting the domestic hot water side (cont.)
Safety valve
Equip the system with a type−tested
diaphragm safety valve as protection
against overpressure.
Permiss. operating pressure: 10bar.
The connection diameter of the
safety valve should be R½" (DN15).
Consequently, the max. permissible
heating load would be 75kW. If the
heating load of the DHW cylinder is
above 75kW, select a larger safety
valve that is large enough for the
actual heating load (see DIN47531,
issue3/88, section6.3.1).
Install the safety valve in the cold
water pipe. It must not be able to be
isolated from the DHW cylinder.
The pipework between the safety
valve and the DHW cylinder must not
be restricted in any way. The safety
valve blow−off line must not be able
to be closed. Expelled water should
be safely and visibly drained into a
waste water facility. It is advisable to
place a sign close to the safety valve
blow−off line or on the safety valve
itself with the following inscription:
"For safety reasons, water may be
discharged from the blow−off line
during heating. Never seal off."
Install the safety valve above the top
edge of the DHW cylinder.
