Unit for air to water heat pump system

Using the table below, determine if the expansion vessel pre-
pressure requires adjustment.

3

Using the table and instructions below, determine if the total
water volume in the installation is below the maximum allowed
water volume.

Calculating the pre-pressure of the expansion vessel

The pre-pressure (Pg) to be set depends on the maximum
installation height difference (H) and is calculated as below:

Pg=(H/10+0.3) bar

Checking the maximum allowed water volume

To determine the maximum allowed water volume in the entire circuit,
proceed as follows:

1

Determine for the calculated pre-pressure (Pg) the
corresponding maximum water volume using the graph below.

2

Check that the total water volume in the entire water circuit is
lower than this value.

If this is not the case, the expansion vessel inside the unit is too small
for the installation.

figure "Maximum allowed water volume"

Example 1

The unit is installed 5 m below the highest point in the water circuit.
The total water volume in the water circuit is 100 l.

In this example, no action or adjustment is required.

Example 2

The unit is installed at the highest point in the water circuit. The total
water volume in the water circuit (no glycol used) is 350 l.

Result:

Since 350 l is higher than 280 l, the pre-pressure must be
decreased (see table above).

The required pre-pressure is: 
Pg=(H/10+0.3) bar=(0/10+0.3) bar=0.3 bar

The corresponding maximum water volume can be read from
the graph: approximately 410 l.

Since the total water volume (350 l) is below the maximum water
volume (410 l), the expansion vessel suffices for the installation.

Setting the pre-pressure of the expansion vessel

When it is required to change the default pre-pressure of the
expansion vessel (1 bar), keep in mind the following guidelines:

Use only dry nitrogen to set the expansion vessel pre-pressure.

Inappropriate setting of the expansion vessel pre-pressure will
lead to malfunction of the system. Therefore, the pre-pressure
should only be adjusted by an installer.

Connecting the water circuit

Water connections must be made in accordance with the applicable
legislation and the outlook diagram delivered with the unit, respecting
the water in- and outlet.

NOTICE

When circulation in each space heating loop is controlled
by  remotely controlled valves, it is important that this
minimum water volume is kept even if all the valves are
closed.

(a)

(a) Installation height difference: height difference (m) between the highest point of 

the water circuit and the unit. If the 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 

decreased, calculate 
according to 

"Calculating the 

pre-pressure of the

Actions required:

• pre-pressure must be 

increased, calculate
