cleaning and rinsing of unit components
CAUTION!
Unit components may be cleaned and
rinsed only by customer service personnel
authorized by the manufacturer. Use only
liquids recommended by the manufactur-
er.
Rinsing of the liqueer with chemical
cleaning agents must be followed by neu-
tralization of residue and intensive rinsing
with water. Always observe the technical
data of the manufacturer of the heat ex-
changer.
rinsing and filling the heat source
Contamination and deposits in the heat source can cause
malfunctions.
Proceed as follows:
Rinse heat source system thoroughly…
Thoroughly mix the anti-freeze agent, available
as an accessory, with water at the required ratio.
Add only anti-freeze mixed with water to the heat
source…
Check concentration of anti-freeze in the mixture…
ATTE NTION
The concentration of anti-freeze in the water
must be at the level specied for your model.

water quality of the fill and additional water
in hot water heating systems
according to vdi 2035 part i and ii
Use of modern, energy-efcient heat pump systems
is becoming increasingly widespread. Their ingenious
technology enables these systems to achieve very good
efciencies. The decreasing space available for heat
generators has led to the development of compact
units with increasingly smaller cross-sections and high
capacities. This means the complexity of the systems and
the material diversity are also increasing, which plays an
important role especially in their corrosion behaviour.
Alpha InnoTec ensures continuous technological
advances, but all these technical renements require
the system to be operated with correctly lled heating
water. The heating water not only affects the efciency
of the system, but also the life of the heat generator and
the heating components of a system.
The guide values of VDI 2035 Part I and Part II must
therefore be complied with as minimum requirements
for proper operation of the systems. Our practical
experience has shown that the safest and most trouble-
free running of the systems is achieved with so-called
low-salt operation.
VDI 2035 Part I gives important information and
recommendations regarding scaling and its prevention in
heating and domestic hot water heating systems.
VDI 2035 Part II primarily deals with the requirements
for reducing heating water corrosion in hot water
heating systems.
principles of part i and part ii
The occurrence of scaling and corrosion damage in hot
water heating systems is low, if
- proper planning and commissioning is carried out
- the system is closed in corrosion terms
- adequately dimensioned pressurising is integrated
- the guide values for the heating water are complied
