Section 6: Installation of the Heat Pump
Page 21
6.2.2 Pipework connections
Make the flow and return connections between the boiler and heat
pump, using the fittings provided with the boiler, as follows:
1. Using a suitable thread sealant or PTFE tape, screw one of
the two flexible hoses into the 1”BSPF ‘Heat Pump Flow’
connection on the boiler.
2. Repeat the above process to fit the second flexible hose to
the1”BSPF ‘Heat Pump Return’ connection on the boiler.
3. Using a suitable thread sealant or PTFE tape screw the
1”BSPM x 28mm tail into the 1” x 1¼” elbow. Then fit the elbow
to the flow connection (the higher of the two connections) on
the rear of the heat pump.
4. Fit the 28mm compression connection on the end of the flexible
hose from the heat pump flow connection (on to the boiler) on
to the tail fitted to the heat pump flow connection. Tighten the
compression connection.
5. It may be necessary to adjust the angle of the elbow/tail on the
flow connection to align it with the compression connection on
the end of the flexible hose.
6. Repeat steps 4 and 5 above to connect the heat pump return
on the boiler with the flow connection on the heat pump.
7. Fill the sealed heating system as described in Section 10 of
these instructions.
8. Vent the system to remove trapped air using the manual air
vents located inside the boiler enclosure (refer to Figures 8-2
and 8-3) and also the automatic air vent in the heat pump (refer
to Section 1 of the Installation Instructions supplied with the
Aerona³ heat pump.
6.3 Installing the Heat Pump – Separate from Oil
Boiler (Internal oil boiler)
6.3.1 Electrical connections
1. Move the heat pump into the required final position. Ensure that
it does not obstruct the flue terminal and that the flue terminal
position complies with the necessary clearances. Refer to
Section 2.8.
2. Remove the wiring cover from the right hand end of the
heat pump. Refer to Section 6 of the Installation Instructions
supplied with the Aerona³ heat pump for details.
3. Remove the access panel from the front of the boiler casing.
Unscrew and remove the eight screws that secure the access
panel to the casing. Refer to Figure 12-1.
4. Make the heat pump electrical supply connection between the
heat pump electrical supply terminal block in the hybrid control
panel (in the boiler) and the electrical supply terminal block in
the Aerona³ heat pump.
Refer to Section 12 for electrical connection details. Figure 12-
10 shows the location of this terminal block and Figure 12-11 is
the connection diagram.
5. Make the heat pump controls connection between the heat
pump controls terminal block in the hybrid control panel (in the
boiler) and the Terminal PCB in the Aerona³ heat pump.
Refer to Section 12 for electrical connection details. Figure 12-
12 shows the location of this terminal block and Figure 12-13 is
the connection diagram.
6. Replace the wiring cover on the right hand end of the heat
pump and secure in place with the three fixing screws.
7. When all wiring connections have been made, re-fit the upper
cover panel at the rear of the control panel and secure it using
the two screws at the top of the cover. Refer to Figure 12-3.
8. Then replace the lower cover panel at the rear of the control
panel and secure it using the two screws. Refer to Figure 12-3.
9. Replace the access panel on the front of the boiler casing. Re-
fit and tighten the eight screws to secure the access panel to
the casing. Refer to Figure 12-1.
6.3.2 Pipework connections
Make the flow and return connections between the boiler and heat
pump, using the fittings provided with the boiler, as follows:
1. Using a suitable thread sealant or PTFE tape screw one of
the 1” x 1¼” elbows (supplied with the boiler) on to the flow
connection (the higher of the two connections) on the rear of
the heat pump.
2. Repeat the same process for the return connection (the lower
of the two connections) on the rear of the heat pump.
3. Using a suitable thread sealant or PTFE tape, screw the
1”BSPM thread on one of the two flexible hoses (supplied with
the boiler) into the elbow on the heat pump flow connection.
4. Connect the other end of this flexible hose to the flow pipe from
the boiler using the 28mm compression connection.
5. Repeat the above process to fit the second flexible hose
between the elbow on the heat pump return connection and
the return pipe to the boiler.
6. It may be necessary to adjust the angle of the elbows on the
heat pump flow and return connections to align it with the end
of the flexible hoses.
7. Fill the sealed heating system as described in Section 10 of
these instructions.
8. Vent the system to remove trapped air using the manual air
vents located inside the boiler enclosure (refer to Figures 8-2
and 8-3) and also the automatic air vent in the heat pump (refer
to Section 1 of the Installation Instructions supplied with the
Aerona³ heat pump.
6.4 Heat Pump Parameter Settings
When connected to the boiler as part of the VortexAir Hybrid unit,
some of the Control Parameter factory default settings must be
changed. Refer to Section 15.11 of these Installation Instructions for
details of the Control Parameters to be re-set.
Also, refer to Section 9 of the Installation Instructions supplied with
the Aerona³ heat pump for guidance on how to access and change
the Control Parameters.
