Condenser Modulating Valve - Cornelius 1000 - Series Service Manual

C M
ONDENSER ODULATING
The reason for using a water modulating valve is to supply the correct amount of water to the condenser.
and to maintain a proper operating pressure to refrigeration system high side.
The flow of water through the valve is increased as the high side pressure rises and is decreased as high
side pressure lowers.
To calibrate the amount of water flow with the refrigeration system high side pressure, turn adjustment
screw located on end of valve opposite of bellows. Turn screw counterclockwise to raise opening point or
clockwise to lower opening point. Opening point of valve should be set to maintain proper operating
pressure in refrigeration system high side. Refer to Pressure Chart on. Closing point of valve should be
set low enough to close valve during compressor stand–by periods.
NOTE: Cold water will absorb heat faster than warm water. The water flow will therefore
automatically increase as inlet temperature increases.
