Samsung EHS AE080BXYDEG/EU - Maximum Water Volume

6. Piping installation
Installer reference guide / Mono tank integrated type 60
Maximum water volume
NOTE
The maximum water volume depends on whether glycol is added to the water circuit. For more information
on the addition of glycol.
Use the following graph to determine the maximum water volume for the calculated pre-pressure.

No pre-pressure adjustment required.
Actions required:
Pre-pressure must be decreased, calculate
according to “Calculating the pre-pressure of the
expansion vessel”.
Check if the water volume is lower than maximum
allowed water volume
> 7m
Actions required:
Pre-pressure must be increased, calculate the
appropriate value following by “Calculating the
pre-pressure of the expansion vessel”.
Check if the water volume is lower than maximum
allowed water volume
Expansion vessel of the unit too small for the
installation.
a) Installation height difference: height difference(m) between the highest point of the water circuit and the indoor unit. If the indoor unit is located at
the highest point of the installation, the installation height is considered 0m.
