General Start up

Start Up Preparation
Carry out all operations on check list so that the unit is
correctly installed and ready to operate. The installer
must check all the following points before calling in

• On start-up of each motor in the system, check
the direction of rotation and operation of all the
components they drive.
• Check that there is enough demand for cooling on the
day of the start-up (around 50% of the nominal load as
minimum).
• When ball valve is present on the refrigerant suction
line, to check if the valve is open before starting the
unit.
• Check and set, as required, all Tracer™Symbio800

Technical Data
Water System Flow Rates
Establish a balanced chilled water flow through the
evaporator. The flow rates must fall between the
minimum and maximum values. Chilled water flow
rates below the minimum values will result in laminar

flow, which reduces heat transfer and causes either loss

precautions when exposed to live electrical components

CAUTION! When using freeze inhibitor, never fill the
system with pure glycol. Always fill the system with
diluted solution. Maximum concentration of Glycol is
40%. Higher glycol concentration will damage pump
seal.
CAUTION! The pump must not run dry. Dry-running will
damage the mechanical seal.
CAUTION! Proper Water Treatment! The use of
untreated or improperly treated water in the chiller 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.
CAUTION! Strainer should be cleaned after water flow
has been established for the first time, as it is likely that
it collects all the particles left after field installation.
