6.9.2.2 Filling the heating and cooling circuit
Perform the following steps to ll and vent the heating or cooling circuit:
1. Open the quick vent valve (1), by turning the valve cap (2) of the quick vent valve one
full turn in an anti-clockwise direction (→ 4.6.2.1 Components (split systems), p. 32,
→ 4.6.3.1 Components (compact systems), p. 47).

2. Turn up all thermostat valves of the heating system and possibly all other stop valves.
3. Connect a lling hose which has been vacuumed as far as possible to the water return
of the system (→ 4.6.2.1 Components (split systems), p. 32, → 4.6.3.1 Components
(compact systems), p. 47).
4. Fill water until the manometer shows that the set pressure has been reached.
5. Vent the system as follows:
a. Open the indoor and outdoor unit or the compact device (→ 6.5 Opening devices,
p. 148).
b. Place the lever (2) of the pressure relief valve (1), located in the indoor unit or compact
device (→ 4.6.2.1 Components (split systems), p. 32, → 4.6.3.1 Components (compact
systems), p. 47) in the horizontal position (3 – open). The included air can now escape
audibly (hissing sounds).

3 Setting horizontal in the opening position
c. Set the lever of the pressure relief valve after a few seconds in the home position
(closed).
d. Repeat the sequence until there are no audible sounds of escaping air.
e. Check the system pressure on the manometer. In normal operation, the system pressure
should be between 0.5 and 3 bar. Adjust the set pressure if necessary.
6. Then again check the pressure and top up the uid if necessary.
7. Check whether there are any leakages in the pipeline connections, and repair them if
necessary.
6.9.2 Filling and venting the water system
6.9.2.1 Filling hot water tank
i
Note
The following method describes exclusively how the combination hydro-modules are lled by
Panasonic.
At the time of commissioning split systems with hydro-module or compact systems, which are
used in combination with hot water tanks from third party suppliers, when topping the hot water
tanks, follow the installation instructions of the third party supplier, supplied with the tank. In
such a case, continue with section → 6.9.2.2 Filling the heating and cooling circuit, p. 195.
When commissioning split systems with hydro-module and compact systems which are used
without hot water tanks, you can skip this section. In this case, too continue with section
→ 6.9.2.2 Filling the heating and cooling circuit, p. 195.
Perform the following steps to ll the hot water tank of the combination hydro-module:
1. Set the venting valve on the outlet socket of the hot water tank (→ 4.6.2.1 Components
(split systems), p. 32) to the closed position.
2. Open all hot water taps in the heating system (water and shower taps)
3. Fill the hot water tank through the cold water entry (→ 4.6.2.1 Components (split
systems), p. 32). After 20 to 40 minutes, water should come out of the hot water taps. If
this does not happen, please contact your specialist dealer.
4. Check whether there are any leakages in the pipeline connections, and repair them if
necessary.
