8.4 WATER-COOLED CONDENSER WATER CIRCUITS CONNECTION (ACCESSORY)
For machines with incorporated water-cooling condenser it is necessary to set up the condenser supply and discharge
lines. The diameters of the pipes and the inlet and outlet ttings are identied in the order conrmation or in the following tables for
standard models (identied by the code number sequence).

For models with several circuits the gures are intended per circuit
If the water supply is obtained from a well or river, two lters of suitable characteristics for the type of water must be in-
stalled in parallel, (one as backup for the other) to prevent the condenser from becoming dirty from impurities in the water.
The maximum pressure of the water supply to the water-cooled condensers is 16 bar (1.6 MPa), the minimum is 1 bar (1
MPa).
8.4.1 CONDENSATION PRESSURE ADJUSTMENT MODULATING VALVE (ACCESSORY)
The condensation pressure adjustment modulating valve is indispensable in case of well, river, mains water supply and in
all cases where water temperature might drop during the winter time at such low temperatures (below 15°C) that the machine's
condensation temperature is excessively lowered. The valve is factory-installed on the condenser water outlet.
The positions of the water inlet and outlet connections are indicated in the gure below. The connections can also be iden-
tied by the adhesive labels applied on the panel of the unit near the connections. The maximum pressure of the water supply to the
water-cooled condensers is 16 bar (1.6 MPa), the minimum is 1 bar (1 MPa).
The maximum pressure dierence between the water inlet pipe and the outlet pipe is 1.8 bar (180 kPa), as at pressure
dierences greater than this value the return spring would not be able to shut o the water ow. In the event of greater pressure
dierences, it will be necessary to install pressure reducing valves upstream of the valve.
