! NOTE !
If the backup immersion heater is to be used ensure that
the two semi-pierced knockouts are removed BEFORE the
external volumiser is fitted and piped up to the heat pump.
3. Fit the external volumiser onto the AV mounts, ensuring that
the flow and return connections are facing upwards and the
removable cover is at the right-hand end of the volumiser
when facing the heat pump from the front.
Refer to Figure 3-4.

Figure 3-5: Volumiser mounting brackets
4. Ensure that the base of the External Volumiser is correctly
located between the two upward facing flanges on both of the
mounting brackets. Refer to Figure 3-5.
5. Position the Aerona³ heat pump on the AV mounts, with the
front feet at the end of the metal channel of the mounts.
Tighten the four fixing screws to secure the heat pump feet to
the AV mounts.
The gap between the rear of the heat pump and the front
of the External Volumiser should be approximately 100mm.
Refer to Figure 3-6.
If not, then slacken the four screws securing the heat pump
to the AV mounts and adjust its position to achieve approx.
100mm. Then ensure that the four screws are re-tightened to
secure the heat pump to the AV mounts.
