Enter service test mode from unit Human Interface.
Navigate to the compressor condenser fan submenu.
Under head pressure control, use manual control.
Close drain valve and energize water inlet solenoid
valve until water reaches nominal level. Once level is
achieved, de-energize fill solenoid. Open drain valve
and time how long it takes for the water level to drop
one inch, make sure to take into account the closing
time of the valve.
Chemical Water Treatment Tree
The Trane evaporative condenser comes with a PVC
tree to allow easier inputs for third party water
treatment. The tee labeled A is a 3/4 inch NPT threaded
input, see
Figure 67, p. 95 . Tees B and C are 1/2 inch
NPT threaded inputs. The ball valve can be used to stop
the water flow through the tree to allow the customer
to add hookup of water treatment, or to change and
update water treatment with the unit running.
Units with a conductivity sensor will have the
conductivity sensor installed into the 3/4 inch tee with
the other tees plugged. For all other units, A, B and C
will be plugged, see
Figure 67, p. 95 . Ensure the ball
valve is in the open position when water treatment is
being operated in the system to make sure water flows
through the tree and transports treatment to the unit
sump.

Conductivity Controller
Upon start-up, the conductivity controller must be
calibrated and setup for operation. Below are the
necessary steps to accomplish those tasks. The
controller has two setpoints that control two relays.
Both of these setpoints will need to be set by a local
water treatment expert.
1. The first setpoint is the standard point blowdown
point. When the setpoint is exceeded, the relay (K1)
will be energized and a blowdown request will
close the Water treatment request binary input on
the MCM.
2. The second setpoint will be the emergency point.
The second setpoint will open the normally closed
K2 relay, which will interrupt the sump proving
circuit which will generate a manual lockout. This
second setpoint will be used to protect the unit
from extremely high conductivity that would
indicate a failure in the system.
3. Inside the enclosure for the controller, there will be
