Compressor mounted on a horizontal receiver. Semi-hermetic, air-cooled
4-cylinder reciprocating compressor in compact design. The suction gas is not
heated up by the motor, but rather drawn in directly from into the compressor.
The motor is cooled by means of a compact, integrated ventilation unit, which
cools not only the motor, but also the compressor and in particular the cylinder
heads, by means of targeted air cooling. The best possible serviceability is
provided by means of a replaceable drive motor, among other things. The
compressor stands out due to its outstanding running comfort and efficient
operating performance. Dependable mechanism lubrication is guaranteed by means
of an oil pump which is independent of rotating direction, as well as a
large-volume oil sump. The optional oil sump heating is carried out using an
immersion sleeve and can therefore be replaced without intervening in the
refrigeration cycle. An additional connection facility for an oil level
regulator is available as a standard. The electrical connection is simplified by
means of a large-volume electric terminal box. The electronic motor protection
MP10 with optical status indication uses PTC sensors in series to monitor the
winding temperature and, if desired, the discharge gas temperature.

| 1) | Tolerance (± 10%)
relates to the mean value of the voltage range. Other voltages and current types

All data are based on voltage rms values |
| 2) | - The stated value for the max. power consumption is valid
for the adjusted power supply.
- Starting current (rotor blocked):
- Part winding (PW) motors: Winding 1 / Winding 1+2
- Delta/Star (Δ/Y) motors: Δ / Y
- Take account of the max.
operating current / max. power consumption for designing motor contractors, feed
lines, fuses and motor protection switches. Motor contractors: Consumption

| 3) | The maximum permissible working current of the compressor
(Imax) must not be exceeded. Take account of the guidelines for use of frequency
inverter (see compressor assembly instruction or selection software).

| 5) | Declared dual-number noise emission values are in
accordance with ISO 4871. The corresponding uncertainty to the sound power level
is KWA = 2,5 dB and to the sound pressure level is KpA =
2,5 dB. The values are valid for 50 Hz with the refrigerant R404A at the
standard rating points according to EN 12900.
- A-weighted sound power level LWA (re 1 pW), in decibel. To
determine the values, measurement methods of the ISO 3740 standard with
accuracy class 2 or higher were used .
- A-weighted sound pressure level LpA (re 20 µPa), in decibel.
The values are calculated from the sound power level in accordance with ISO
11203: LpA = LWA - Q2 at a distance of d = 1m
to the reference box.
