Tap water connection
Hot and cold water are connected to pos (74) (hot water)
and (73) (cold water).
The enclosed expansion vessel (107) must be connected to
the hot water system.
The heat pump should be supplemented with an electric
water heater if a bubble pool or other significant consumer
of hot water is installed.
Cleaning the system / Flushing out of
the hot water and the heating sys-
tem
The pipe work must be flushed before the heat pump is
connected, so that any contaminants do not damage the
components parts.
After flushing, an inhibitor should be used for long term
corrosion protection. Ensure all cleanser is removed from
the system before adding the inhibitor.
NIBE Energy Sytems Limited recommends Fernox and
Sentinel water treatment products for heating and cooling
systems.

Setting the pump speed
To set the correct flow in the heating system, the correct
speed must be set for the circulation pump in the differ-
ent operating conditions.
Compare the planned heating with the available capac-
ity for the circulation pump (16) and set the lowest pos-
sible pump speed.
You set the speed for the circulation pump with the help
of the switch on the pump. Choose speed I, II or III. You
can see the chosen speed to the left, above the switch.
The display to the right, above the switch, should not be
lit.
