TABLE OF CONTENTS

1. Important notes
1.1 Safety instructions
Installation and maintenance work can – due to the high
system pressures and high temperatures – be associated
with hazards and may only be performed by specialists.
Moreover, all safety instructions in the respective docu-
ments must be observed.
1.2 Key to symbols used
i
Notice:
Provides important information
Safety information:
Indicates an immediate hazard to persons
Warning information:
Indicate danger to machines and installa-
tions.
1.3 General information
With this purchase you have made a decision for a mo-
dern system. Continuous quality control and enhance-
ments, as well as function tests in the factory, guarantee
a technically awless device.
Please read these instructions through carefully. Our
sales and service personnel will be happy to provide you
with any further information you may require.
Service and maintenance
Regular maintenance and cleaning of the calorier is
necessary for reasons of hygiene and cost-effectiveness.
The cleaning intervals will depend on the water quality,
the operating temperature and the hot water consump-
tion.
Cleaning
If necessary, the system can be cleaned with a damp clo-
th. The usage of cleaning agents is not recommended.
Installation of additional components
The installation of additional components which have not
been tested as a part of the system can cause functional
impairment. Hoval will assume no warranty or liability co-
verage for any resultant damages.
Warranty
With the purchase of the Hoval calorier, you have a com-
prehensive warranty in accordance with our terms of sale
and warranty. Please note that this warranty only applies
if the following work is performed exclusively by an au-
thorised specialist company:
• Set-up, installation, connection and commissioning
• Modications to the installation
• Maintenance and cleaning (interior) and opening of the
ange
• Draining, taking out of operation, putting back into op-
eration

IMPORTANT INFORMATION

2. Asembly
Please note that the calorier may only be
set up, connected and commissioned by
an authorised specialist company.
Modications to the calorier, to the wa-
ter and heating connections as well as to
the electrical connections may only be
carried out by trained technicians. The
safety valve and the exhaust line must not
be modied in any way.

3. Commissioning
The rst time the water is heated and where the system
has been switched off for longer periods, hot water and
the full calorier output only become available after expiry
of the heating-up time. While the water is being heated,
some water will emerge from the exhaust line of the tank
safety valve. This is normal and no cause for concern.
The exhaust line of the safety valve must
remain open at all times.
3.1 Temperature setting
For reasons of economy and hygiene, we recommend
that the hot water temperature is set to 60 °C. A hot water
temperature of 60 °C prevents the formation of legionel-
las and ensures maximum cost effectiveness in line with
the Energy Ordinance. Where the water contains high
levels of calcium carbonate (hard water), the formation of
limescale in the tank and the overall hot water installation
and armatures is delayed.
In addition, there is a danger of scalding
at higher hot water temperatures.
The temperature is normally set at the boiler control pa-
nel of the heat generator. The temperature can also be
set via an adjustable thermostat installed on the calorier
(available as an accessory).
If the calorier is equipped with an electrical heating inset,
the temperature is set via the thermostat dial of the elec-
trical heating inset. In the case of combined systems, e.g.
solar plants, the temperature can also be set via other
control devices.

4. Care and maintenance
4.1 Maintenance, cleaning and inspection
Regular maintenance and cleaning of the calorier is
necessary for reasons of hygiene and cost-effectiveness.
The cleaning intervals will depend on the water quality,
the operating temperature and the hot water consump-
tion.
Cleaning work may only be performed by the Hoval custo-
mer service or an authorised specialist company.
We recommend that you conclude a maintenance cont-
ract with Hoval customer service or an authorised speci-
alist company.
4.1.1 Cleaning the outer jacketCleaning is best perfor-
med with a cloth moistened with a soap solution.
4.2 Taking out of operation / frost protection
• If there is a frost hazard, the calorier must be kept in
operation.
• If it is taken out of operation, the calorier must be com-
pletely drained.
• Hot water may emerge during draining!
Where there is a frost hazard, it is also important to note
that not only the water in the calorier and in the hot water
pipes can freeze, but also that in the cold water pipes and
the armatures. For this reason, it is advisable to drain all
pipes and armatures containing water. The heating water
must also be drained completely on the heating side.
Only an authorised specialist company may drain the
tank and the heating system, take the heating system out
of operation or put it back into operation.
