Maximum Water Volume - Samsung EHS AE050RXYDEG/EU Manual

6. Piping installation

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.
Installation height
difference
a)
≤ 7 m
> 7 m
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.

No pre-pressure adjustment required.
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
