Be careful not to deform the unit’s piping by 

using excessive force when connecting the 

piping. Deforming the piping can cause the unit 

to malfunction.

CAUTION

Selecting the additional expansion vessel
If the expansion vessel of the unit is too small for the 

installation, an additional expansion vessel is needed.

calculate the pre-pressure of the expansion vessel: 

Pg(bar)=(H(m)/10+0.3) bar

the expansion vessel equipped in the unit should 

adjust the pre- pressure also.
calculate the volume needed of the additional expan-

sion vessel:

V1=0.0693*Vwater/(2.5-Pg)-V0

Vwater is volume of water in the system, V0 is volume 

of expansion vessel which the unit is equipped(8L).

9.4.3  Water circuit connection

Water connections must be made correctly in 

accordance with labels on the outdoor unit, with respect 

to the water inlet and water outlet.

Use clean pipes only.
Hold the pipe end downwards when removing burrs.
Cover the pipe end when inserting it through a wall to 

prevent dust and dirt entering.
Use a good thread sealant for sealing the connec-

tions. The sealing must be able to withstand the 

pressures and temperatures of the system.
When using non-copper metallic piping, be sure to 

insulate two kind of materials from each other to 

prevent galvanic corrosion.

If air, moisture or dust gets in the water circuit, problems 

may occur. Therefore, always take into account the 

following when connecting the water circuit:

For copper is a soft material, 

use appropriate tools for 

connecting the water circuit. 

Inappropriate tools will cause 

damage to the pipes.

Pre-pressure = pre-pressure of the expansion vessel

Maximum water volume = maximum water volume in the 

system
A1  System without glycol 
A2 System without 25% propylene glycol

Example 1

The unit is installed 5m 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 is 250 

L.
Result:

Since 250 L is more than 230 L, the pre-pressure 

must be decreased (see table above).
The required pre-pressure is: Pg(bar) = 

(H(m)/10+0.3) bar = (0/10+0.3) bar = 0.3 bar
The corresponding maximum water volume can be 

read from the graph: approximately 310L.
Since the total water volume (250L) is below the 

maximum water volume (310L), 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 (1.0 bar), following guidelines:

Use only dry nitrogen to set the expansion vessel 

pre-pressure.
Inappropriate setting of the expansion vessel 

pre-pressure will lead to malfunctioning of the 

system. Pre-pressure should only be adjusted by a 

licensed installer.

Determine the calculated pre-pressure (Pg) for the 

corresponding maximum water volume using the 

graph below.
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.

NOTE

Never use Zn-coated parts in the water 

circuit. Excessive corrosion of these parts 

may occur as copper piping is used in the 

unit's internal water circuit.
When using a 3-way valve in the water circuit. 

Preferably choose a ball type 3-way valve to 

guarantee full separation between the 

domestic hot water and floor heating water 

circuit.
When using a 3-way valve or a 2-way valve in 

the water circuit. The recommended 

maximum changeover time of the valve 

should be less than 60 seconds.

The unit is only to be used in a closed water 

system. Application in an open water circuit can 

lead to excessive corrosion of the water piping:

9.4.4  Water circuit anti-freeze protection

Ice formation can cause damage to the hydraulic system. 

As the outdoor unit may be exposed to sub-zero 

temperatures, care must be taken to prevent freezing of 

the system.

All internal hydronic parts are insulated to reduce heat 

loss. Insulation must also be added to the field piping.

The software contains special functions using the heat 

pump to protect the entire system against freezing. When 

the temperature of the water flow in the system drops to 

a certain value, the unit will heat the water, either using 

the heat pump, the electric heating tap, or the backup 

heater. The freeze protection function will turn off only 

when the temperature increases to a certain value.

In event of a power failure, the above features would not 

protect the unit from freezing.

Do one of the following to protect the water circuit 

against freezing:

Add  glycol  to  the  water.  Glycol  lowers  the  freezing 

point  of  the water.

Install freeze protection valves. Freeze protection 

valves drain the water from the system before it can 

freeze.

1. Freeze protection by glycol

About freeze protection by glycol

Adding glycol to the water lowers the freezing point of water.

Types of glycol

The types of glycol that can be used depend on whether the

system contains a domestic hot water tank: 

    If the system contains a domestic hot water tank, then only

use propylene glycol*;

    If the system does NOT contain a domestic hot water tank, 

then you can use either propylene glycol* or ethylene glycol;

*Propylene glycol, including the necessary inhibitors, classified as 

 Category III according to EN1717.

Required concentration of glycol

The required concentration of glycol depends on the lowest 

expected outdoor temperature, and on whether you want to 

protect the system from bursting or from freezing. To prevent 

the system from freezing, more glycol is required.

Add glycol according to the table below

:

If you add glycol to the water, do NOT install 

freeze protection valves. Possible conse-

quence: Glycol leaking out of the freeze 

protection valves.

WARNING

Ethylene glycol is toxic.

WARNING

Due to the presence of glycol, corrosion of the system is

possible. Uninhibited glycol will turn acidic under the

influence of oxygen. This process is accelerated by the

presence of copper and high temperatures. The acidic

uninhibited glycol attacks metal surfaces and forms

galvanic corrosion cells that cause severe damage to the

system. Therefore it is important that:

 ▪  the water treatment is correctly executed by a qualified

water specialist,

 ▪ a glycol with corrosion inhibitors is selected to counteract

 acids formed by the oxidation of glycols,

 ▪ no automotive glycol is used because their corrosion

inhibitors have a limited lifetime and contain silicates which 

can foul or plug the system,

 ▪ galvanized pipes are NOT used in glycol systems since

the presence may lead to the precipitation of certain

components in the glycol's corrosion inhibitor.

Glycol absorbs water from its environment. Therefore do

NOT add glycol that has been exposed to air. Leaving the

cap off the glycol container causes the concentration of

water to increase. The glycol concentration is then lower

than assumed. As a result, the hydraulic components

might freeze up after all. Take preventive actions to ensure

a minimal exposure of the glycol to air.
