Installation
Final Water Piping Connections
1. All water piping to the system should be flushed thoroughly before mak-
ing the final connections.
CAUTION
Pump Damage!
If using an acidic commercial flushing solution, construct a temporary
bypass around the pump and unit. Failure to do so may lead to
equipment damage.
2. Connect the water pipe to the EVP chiller.
3. Ensure the drain shutoff valve is closed.
4. While filling the chiller system with solution, vent the air from the system
at the highest points.
CAUTION
Proper Water Treatment!
The use of untreated or improperly treated water in an Air-Cooled Cold
Generator may result in scaling, erosion, corrosion, algae or slime. It is
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.
Evaporator Water Piping
The unit's water connection sizes and locations are shown in Figure 4.
CAUTION
Component Damage!
Evaporator pressure should not exceed 150 psig (i.e., maximum working
pressure). Failure to do so may lead to equipment damage.
CAUTION
Pump Damage!
Do not reverse system water piping connections to the unit or pump.
Failure to follow these instructions may result in pump or unit damage.
Water entering the evaporator is pre-piped to the discharge of the pump. If
the pump is not required, open bypass valve and close inlet and discharge
valves on pump. "Water Inlet" to the evaporator must enter on inlet
connection to pump. Leaving water must exit the evaporator through the
designated "Water Outlet" connection.
