Water-Cooled Condenser Connections (Water-Cooled Machines Only)
The water regulating valve is not installed on the condenser when it is shipped from the factory. Install the
regulating valve on the condenser water inlet connection (bottom connection on condenser). Connect the
condenser water outlet line to the top connection on the condenser.

Cooling Tower (Water-Cooled Machines Only)
When selecting a cooling tower, pay careful attention to operating wet bulb conditions. Check with your local
cooling tower distributor for their recommendations based on actual operating conditions in your area. An
average wet bulb temperature of 78°F (25°C) is typical in the United States, but many localities have design wet
bulb temperatures as low as 72°F (22°C) or as high as 82°F (28°C). All standard Vogt-supplied cooling towers are
sized for 78°F (25°C).
The cooling tower water pump must be capable of delivering the required volume of water through the
condenser. The pump must be sized for each installation, which depends on cooling tower location, pressure
drop through water lines, and water regulating valves. The water piping for the cooling tower and the
installation of the pump must be in accordance with the manufacturer’s instructions.
Proper water treatment for the prevention of mineral and foreign matter accumulation in the condenser or
cooling tower is recommended. A water analysis by an independent laboratory should be completed to
determine the proper chemicals to use.
