Prior to Initial Operation
After the pressure has been tested, the vacuum pump
must be connected to the valve connections of the out-
door part (see section “Impermeability Check”) by means
of the manometer station and a vacuum created.
Prior to initial operation of the unit and after the cold cy-
cle has been serviced, the following checks must be
performed:
à Check all refrigerant lines and valves for leaks with a
leak locator spray or soapy water.
à Check that the connection lines did not get switched
by mistake (especially for the RKM series 600 and
700).
à Check the refrigerant lines and the insulation for
damage.
à Check that the electrical connection between the in-
door unit and the outdoor part has the correct polar-
ity.
à Check all fixtures and suspended parts to ensure
that they are in the proper position and at the correct
height.
à If the refrigerant line is longer than 5 m, more refrig-
erant should be added to the system.
Procedure:
1. Remove the vacuum pump and connect the filling
cylinder.
2. Place the open cylinder on a scale and calibrate the
scale to zero.
3. Create a vacuum in the hose at the height of the ma-
nometer distribution pipe.
4. Determine the required amount based on the infor-
mation in the table above and open the suction pres-
sure side of the manometer to begin the filling proc-
ess.
5. Close the manometer valve when the appropriate
amount has been added.
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.
3. 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 normalises.
4. Keep in mind that the pump automatically switches
off once the water has been pumped out of the res-
ervoir.
5. If, upon initial operation, there is a lot of noise from
vibrating hoses, insulate these hoses using foam
hoses.
Condensation buildup is prevented when using insu-
lated hoses sealed against diffusion.
6. Check the function of the alarm contact by drastically
increasing the amount of water.
The alarm contact should switch off the unit.
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 con-
densation 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 form-
ing.
The 6 mm (inner diameter) thick hose is placed at a
maximum height difference of 6 meters to the drain.
The condensation line should be as vertical as possible
to guide the condensation.
If the pump is installed outside the unit, a maxi-
mum height difference of 3 m between the lower
edge of the unit and the pump mounted above
may not be exceeded.
Adding refrigerant
The additional refrigerant amount required is based on
the length and the diameter of the pressure line.
