Okofen 600, Руководство по установке

Страница: 29 / 32

Date of the test
1 Has the DHW mixer been installed correctly?
2 How high is the maximum static pressure (below 10
bar)?
3 How high is the flow pressure? (between 0.2 and 5
bar)
4 How high is the hot water feed temperature (tempera-
ture range between 52 and 80°C)?
5 How high is the cold water feed temperature (temper-
ature range between 5 and 20°C)?
6 How high has the mixed water temperature been set?
7 How high is the mixed
water temperature at
higher flow velocities?
(maximum opening of the
water consumer) Flow velocity:
Max. mixed water temp.:
Final mixed water temp.:
8 How high is the mixed
water temperature at low
flow velocity?
(small opening of the
water consumer) Flow velocity:
Max. mixed water temp.:
Final mixed water temp.:
9 Make a note of which water consumer was opened for
the test and which temperature measuring device was
used.
The final temperature of the mixed water must be determined and set on a building-
specific basis.
Parameters such as scalding protection, piping protection and energy-saving settings
must be considered.
Higher temperatures than the final temperature may only occur momentarily.
Malfunction of the DHW mixer
A test must be conducted in the same way as during initial startup (as described
above). Use the same water consumers and temperature measuring devices.
If the temperature of the mixed water differs substantially from the previous results
(e.g. > 1 K), the following points must be checked before any settings are changed:
1
.
Cleanliness of all in-line filters and integrated sieves.
2
.
Proper function of all in-line stop valves and integrated stop valves.
3
.
Complete opening of the stop valves.
