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
subsitute for regular water treatment by a
qualified water treatment professional. If a
water treatment system is not operating on
the unit, do not proceed.

Thermostatic Expansion Valves
The reliability and performance of the refrigeration system
is heavily dependent upon proper expansion valve
adjustment.Therefore, the importance of maintaining the
proper superheat cannot be over emphasized.
On air-cooled units, the expansion valves shipped
installed were factory set to control between 14-18°F at the
ARI full load rating conditions (approximately 45°/125°F saturated suction/discharge). On evaporative condenser
units, the...

Note:The burner capacity is controlled by the movement
of the air damper. This has been preset at the
factory and normally does not need field
adjustment. The combustion quality (air/gas) is
controlled by the setup of the air damper and
butterfly valve linkage relationship.
