The unit includes an ion generator for generating negative ions.
High levels of negative ions may be found in mountain regions, near
waterfalls or in forests. Humans perceive such air to be "pure" when
they are breathing it in. In contrast, indoor rooms usually contain low
concentrations of ions. The ion generator enriches the oxygen molecules
in the circulated air to improve the air quality for humans. Suspended
particles and dust are bound in the air to facilitate natural air purification.
Ionisation causes the dust to settle on smooth surfaces where it can be
wiped away. Ensure the housing and filter are cleaned on a weekly basis
when using ionisation. This function is available in all operating modes.

It may be necessary to fit a reducer
or flared adapter to the indoor
unit.
These fittings are included as
standard.

Once installed, the connections
should be made tight against
vapour diffusion.

2. Open the display cover(Fig 6)
and remove the four screws
below the filter(Fig 7).

Condensation connection

If the temperature falls below the
dew point, condensation will form
on the vaporiser of the indoor unit
during cooling.

The collection tray below the
vaporiser should be connected to
the drain.

■

The condensation pipe should
have a fall of min. 2 %. This
is the responsibility of the
customer.(Fig 10). If necessary,
fit vapour diffusion tight
insulation.

■

The condensation pipe from
the unit should run freely
into the drainage pipe. If the
condensation runs directly
into a sewer pipe, fit a trap to
prevent any unpleasant odours.

■

When operating the unit at
outdoor temperatures below
0 °C, ensure the condensation
pipe is laid to protect it
against frost. If necessary, fit
supplementary pipe heating.

■

Once the pipe has been laid,
check the condensation drains
off and permanently seal it.

NOTE

The condensation pump
cannot be built into the unit.

Electrical connection

A protected mains supply and
control cable should be connected
to the outdoor component and
indoor unit respectively.

CAUTION

All electrical installation
work should be performed
by specialist contractors.
Isolate the voltage supply
when connecting the electrical
terminals.

■

We recommend that customers
install a main/repair switch
in the vicinity of the outdoor
component.

■

The terminal blocks for making
the connections are located at
the rear of the unit. When the
unit is installed, measurements
can be made from the front by
removing the cover.

Connecting the indoor unit

Make the connection as follows:

1. Dismantle the front of the unit
as described in the chapter
"Installing the unit".

2. Select the cable cross-section
according to the relevant
standards.

3. Connect the mains supply to
the unit and the control cable
to the outdoor component
(see electrical connection
diagram).

4. Re-assemble the unit.
