Mounting
Install HPAC 40 using the supplied mounting brackets,
which should be screwed into place first, see the follow-
ing illustration.
Then mount HPAC 40 on the brackets. HPAC 40 can
now be easily moved sideways, which facilitates pipe
installation.
NOTE
Install the accompanying securing plate any-
where at the bottom rear of HPAC 40 for fur-
ther fastening.
Inspection of the installation
In accordance with current norms, the heating/cooling
installation must undergo an installation check before
being used. The inspection must be carried out by a
suitably qualified person and should be documented.
The above applies to closed heating/cooling installa-
tions. If the heat pump or the HPAC module are re-
placed the installation must be inspected again.
Control
The cooling supply to the building is controlled by the
flow temperature settings in menu 1.9.5.
When the cooling requirement is large and passive
cooling is not sufficient, active cooling is engaged at
the set degree minute value.
When the demand for cooling has stopped and the
heat pump is to return to heating mode or vice versa,
there is at least a 2 hour delay (adjustable in menu
1.9.5) before switching.
Passive cooling
When passive cooling is required, the circulation pumps
in the heat pump start, to circulate fluid from the sur-
face soil/rock collector through the building's distribu-
tion system and cool the building. Cooling comes from
the surface soil/rock collector.
Active cooling.
With active cooling the compressor in the heat pump
starts and the resulting cold medium circulates to the
building's distribution system and the heat circulates
out to the surface soil/rock collector.
Supply pump exercise
The circulation pump exercises 12 hours after last op-
eration.
