2.12.2 Condensation control with well water

If ground water is used to cool the condenser, install a normally regulating control valve, direct drive, at condenser outlet.

This regulating valve must ensure an adequate condensing pressure in the case where the water temperature entering the

condenser is less than 20° C.

A service valve with pressure outlet is provided on the condenser shell for this purpose.

The valve must modulate its opening according to condensing pressure. When the machine shuts down, the valve will

close preventing the condenser from emptying.

2.13 Chilled water control sensor

The water cooled EWWD(H) VZ unit is equipped with a microprocessor. Be careful when working around the unit to avoid

damaging cables and sensors. Check cables before starting the unit. Prevent rubbing of the cables on the frame or other

components. Make sure the cables are securely locked. If the temperature sensor is removed for maintenance, do not

eliminate the conductive paste in the well and replace the sensor correctly. After replacing the sensor, tighten the lock nut

to prevent accidental slipping.
