Unit Start Up
Evaporative Condenser Startup
Important:
Water treatment by a qualified water treatment expert is required to ensure proper
equipment life and product performance. Dolphin Water Care is an option offered by
Trane that is NOT a substitute for regular water treatment by a qualified water
treatment professional. If a water treatment system is not operating on the unit, do
not proceed.
Startup for evaporative and air-cooled condensers is initially the same. In addition, the following
is required for evaporative condensers prior to startup:
•
All water and drain connections must be checked and verified
•
Evaporative condensers will ship with a fan support bracket to reduce damage caused by
vibration during shipment. The shipping support brackets must be removed prior to unit
startup. See
“To remove shipping brackets,” p. 140
and
Figure 60, p. 141
for removal
instructions.
•
Verify that inlet water pressure is 35-60 PSIG, dynamic pressure (measured with the valve open)
•
Verify that drain valve is set to “drain during power loss” or “hold during power loss” per job
specification
•
Upon a call for cooling, the sump will fill with water. Verify that the sump fills to a level within
the slot on the max float bracket as shown in
