Steps - commissioning, inspection and maintenance

5692 891 GB

Filling the heating system

1. Check the pre-charge pressure of the

diaphragm expansion vessel.

If the pre-charge pressure is lower

than the static system pressure, top

up with nitrogen until the pre-charge

pressure has risen 0.1 to 0.2 bar.

Adjust the pre-charge pressure

accordingly if it is too high.

2. Open the check valves.

3. Top up your heating system with

water and vent until the charge pres-

sure is 0.1 to 0.2 bar higher than the

pre-charge pressure of the dia-

phragm expansion vessel.

Permiss. operating pressure: 3 bar

Test pressure: 4 bar

4. Mark the charge pressure at pressure

gauge A.

5. Return the check valves to their oper-

ating position.

Switching the power on

After switching the power on, a commissioning sequence commences:

■ Select language

■ Set time and date

■ Supply system configuration

■ Supply system commissioning
