For The Installer; Installation - Nibe PKM 10 Montageanweisung

GB
General
PKM makes it possible to obtain passive cooling from
rock, groundwater or surface soil collectors. When using
a surface soil collector the quality of the ground may
limit the possibility to recover passive cooling.
The distribution system is preferably a floor system,
which then becomes a cooling and heating emitter.
Cooling starts when the outdoor temperature exceeds
the set temperature and is then controlled by the selec-
ted cooling curve. A room sensor, RG 10 (accessory), can
be used to give the best comfort. The lowest permitted
flow temperature should be chosen to prevent conden-
sation precipitation.

For the Installer

The cooling module is mounted on the wall.
NOTE! Make an extra check to ensure that all couplings
are tightened, both inside and outside of the PKM, after
the PKM is installed and mounted.
NOTE! Do not use the pipes as a handle.

Installation

When installing on a wall use the supplied mounting
brackets, these are screwed to the wall first, see the pic-
ture below. The cooling module is then mounted on the
bracket. The cooling module is now easy to shift to the
sides, which makes pipe installation that much simpler.
NOTE! Fit the supplied securing plate as a tip guard in
an optional position at the base of the cooling module's
rear to provide additional fixing.

Heating/cooling mode Shuntventil
The circulation pump only runs in cooling mode. The
factory setting for the speed of the circulation pump is
at the MAX position.
Cooling mode is activated when both the shunt and
shuttle valves are open as illustrated.

In cooling mode "PC" is shown on the bottom row in
the heatpump display.
When cooling has been activated, heating mode is
blocked for 3 hours to prevent self-oscillation between
cooling and heating. Quick start can be set to "Yes" in
menu 9.3 to bypass the time block and activate heating
mode directly.
