Proper Water Treatment!
The use of untreated or improperly treated water in a CenTraVac

recommended that the services of a qualified water treatment
specialist be engaged to determine what water treatment, if any,
is required. Trane assumes no responsibility for equipment
failures which result from untreated or improperly treated water,
or saline or brackish water.

is circulating, inspect all piping for leakage. Make any necessary repairs
before starting the unit.
6. While the water is circulating, adjust the water flows and check the water
pressure drops through the evaporator and the condenser. Refer to
"Water System Flow Rates" and "Water System Pressure Drop" .
