Important
—
Although the heat pump is electrically isolated from the rest of the unit, this only prevents
the passage of electricity to or from the pool water. Grounding the unit is still requi r e d t o p r o t e c t
yourself from short circuits inside the unit. Make for adequate ground connection.
Check if the electrical mains voltage corresponds with the
operating
voltage of the heat pump prior to
hooking up
the unit.
It is recommended to use a separate fuse
(
slow type

-
curve
)
as well
as
adequate wiring
(
see
table
below
) .
For horizontal models : remove the panel on the right of the fan opening.
For vertical models: remove the curve panel in the front side.
Connect the electrical wires with the terminal block labelled “Power
Supply”
.
Next to this connection, there is a second terminal block labelled “Water
Pump
”,
to
which
the
filter
pump
(
max
.
5A
/
240V
)
can be
connected
.
This connection
makes it possible to control filter
pump operation with the heat pump. See further at Parameter setting table (Parameter 9) for the
different possibilities.
Remarks
—
for models with 3 phases, switching 2 phases may cause in inversion in the rotational direction
of electrical motors, which could damage the unit. Therefore, a protection device has been built in, which
will interrupt the circuit if the connection has not been performed correctly.
