Connections of the condensation pump on the wa-
ter side
The reservoir is attached to the condensation collection
tray connection of the indoor unit via a customer-
supplied hose (20 mm Ø). The factory-installed flexible
hose of the condensation tray must be disassembled.
The supplied ventilation hose must be used for the res-
ervoir to function properly.
The end of the ventilation hose must at least be at the
same height as the condensation tray to prevent water
from overflowing. The supplied metal wire clips are
used to secure the hose in a vertical position
Keep the hose from being suspended which will prevent
an air pocket from forming.
Prior to Initial Operation
After the pressure check has been performed, the vac-
uum pump must be connected to the valve connections
of the outdoor part (see section “Impermeability Check”)
by means of the manometer station and a vacuum cre-
ated.
Prior to initial operation of the unit and after contact with
the cold cycle, the following checks must be performed
and documented in the initial operation log:
à
Check the refrigerant lines, the outdoor part and the
indoor unit to ensure that any remaining moisture
has been completely removed.
à
Check all refrigerant lines and shut-off valves for
leaks with a leak locator spray or soapy water when
the unit is not in operation.
à
Check that the electrical connection between the in-
door unit and the outer part has been correctly at-
tached.
à
Check the electrical control line to ensure that it is
securely attached in the terminals.
Loose lines in the terminals can cause fires.
à
Check the refrigerant lines and insulation for dam-
age.
à
Check all fixtures and suspended parts to ensure
that they are in the proper position and at the correct
height.
G
If the refrigerant line is longer than 5 m, more re-
frigerant should be added to the system
.
Electrical connection of the condensation pump
There is an electrical connection area located under the
hose connections. This area also a cover that can be
taken on and off.
The pump is equipped with an alarm contact that
switches off the indoor unit and can also control a cus-
tomer-installed malfunction/alarm system.
The electrical connections may only be made by author-
ised service personnel in accordance with the relevant
regulations.
Local guidelines for operation as well as the require-
ments established by local energy supply companies
must be observed for setup and initial operation.
Initial operation of the condensation pump
Before putting the pump into operation, the lines that
have been laid must be checked to ensure that they are
functioning properly and leakproof.
1. Switch the power supply of the pump on.
2. Pour distilled water into the condensation tray until
the pump switches on from the reservoir.
Pump operation can be heard when it is being oper-
ated for the first time or being put back into opera-
tion. After it has run for short period, the noise nor-
malises.
3. Keep in mind that the pump automatically switches
off once the water has been pumped out of the res-
ervoir.
4. If upon initial operation there is a lot of noise from vi-
brating hoses, insulate these hoses using foam
hoses.
Condensation buildup is prevented when using insu-
lated hoses sealed against diffusion.
5. Check the function of the alarm contact by drastically
increasing the amount of water.
The alarm contact should switch off the unit.
G
Always use a contactor or relay to switch off the
outdoor part!
The 6 mm (inner diameter) thick hose is placed at a
maximum height difference of 6 meters to the drain.
If the pump is installed outside the unit, a maximum
height difference of 3 meters between the lower edge of
the unit and the pump mounted above may not be ex-
ceeded. The condensation line should be as vertical as
possible to guide the condensation.
The reservoir and pump are connected to one another
with the long suction hose and the plugable sensor line
from the reservoir. To ensure that the pump operates as
quietly as possible, the suction hose should not be
shortened.
