Wiring Diagram

Connecting the outdoor part

The connections of the outdoor part are located inside
the unit above the connection valves. Proceed as fol-
lows to connect the lines:

1. Remove the cover of the terminal strip on the right-

hand side of outdoor part.

2. Guide the lines through the strain relief.
3. Connect the customer-supplied connection lines of

the units to the outdoor part and the indoor unit as
shown in the figure below.

4. Also connect the sensor line of the RKS 350 H unit

to the corresponding connections on the outdoor part
and indoor unit.

5. Secure the control lines in the strain relief and re-

place the cover of the terminal strip.

Condensation


Condensation flow to the outdoor part

Condensation forms during heating operation on the
plate fin exchanger of the outdoor part because tem-
peratures below the dew point are reached.
The lower housing panel of the outdoor part is designed
to function as a drain tray. A condensation connection
has been supplied beneath the condenser or in the cen-
tre of the tray to be used by means of the seal.
If the unit is used for heating in areas susceptible to
frost, the lower housing panel must be kept free of frost
to ensure that the condensation can always drain out.

Condensation drainage on the indoor unit

Condensation forms during cooling operation on the
plate fin exchanger of the outdoor part because tem-
peratures below the dew point are reached.
The drainage trays of the indoor units are equipped with
a condensation hose. This hose must be placed at an
incline to ensure that the condensation drains.

Condensation hose on the outdoor part

Condensation can be guided over longer distances us-
ing a customer-supplied condensation hose.
Ensure the following before laying the condensation
hose:

à

Make sure that there is an adequate incline for drain-
age.
Minimum of 2 %.

à

When the unit is in operation at an outside tempera-
ture of below 0 °C, the hose must be protected
against frost.
If necessary, use a hose heating mechanism.

à

Always use suitable hose clips.

à

After the hoses have been put into place, you must
check that the condensation flows freely.

1. Place the seal on the hose

connection piece.

2. Press the connection piece

into the opening for this pur-
pose.
