set shaft adapter to 0 degrees
Set Drain Duration Timer
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
TheTrane evaporative condenser comes with a PVC tree to
allow easier inputs for third party water treatment.The tee
labeled A is a ¾ inch NPT threaded input, see
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 Dolphin WaterCare or conductivity sensor will
have the conductivity sensor installed into the ¾ inch tee
with the other tees plugged. For all other units, A, B and C
will be plugged, see Figure
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 startup, 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 Dolphin or a local water
treatment expert.
• The first setpoint is the standard point blowdown
point.
To hold during power loss,
set shaft adapter to 90 degrees
