General Information
General
All Trane Products are identified by
a model number that Precisely
identifies the unit. An explanation of
the alphanumeric identification codes
for CGAT units is provided on the next
page.
Its use will enable the owner /operator,
installing contractors and service
engineers to define the operation,
components and options for any
specific unit.
When ordering replacement parts or
requesting service, be sure to refer to
the serial number and specific model
number stamped on the unit name-
plate.
Unit Nameplate
The unit nameplate specifies the unit’s
specific model number, serial number,
electrical characteristics, type of
refrigerant and other pertinent unit
data.
General Information
All model CGAT air-cooled chillers are
designed for outdoor installation with
vertical air discharge. Each refrigerant
circuit is provided with an operating
charge of refrigerant and refrigerant
oil, a filler drier, high and low pressure
schraeder valve and externally
equalized thermostatic expansion
valve. All units are dehydrated, leak
tested, charged and tested for proper
control operation before shipment. An
access panel(s) provides access to the
compressor section(s), and a remov-
able cover allows access to the
control box.
The brazed plate heat evaporators
used in these units are with integral
distributor. Each evaporator is fully
insulated. Standard capacity and
safety controls are provided. Unit
operation is governed by chilled water
temperature entering the evaporator.
Rigging
WARNING: To prevent injury or death
and unit damage, observe handling
cautions and procedures given in
Figure 1 when lifting the unit. Always
test-lift the unit to determine actual
centre of gravity.
Before preparing the unit for lifting,
estimate the approximate centre
of gravity for lifting safety. Due to the
placement of internal components,
the unit weights may be unevenly
distributed. Unit shipping weights
are provided in the table below.
Lifting Recommendations
Before preparing the unit for lifting,
estimate the approximate center of
gravity for lifting safety. Because of
placement of internal components,
the unit weight may be unevenly
distributed. Approximate unit weights
are given in Table 1.
WARNING : On-sight lifting equipment
must be capable of lifting the unit
weight with an adequate safety factor.
The use of under-capacity lifting
devices may result in severe personal
injury or death and can seriously
damage the unit.
The crated unit can be moved using
a forklift of suitable capacity. For lifting
the unit, attach lifting straps or slings
securely to the lifting holes at each
corner. Use spreader bars to protect
the unit casing from damage. Test lift
the unit to determine proper balance
and stability.
CAUTION : Use spreader bars to
prevent lifting straps from damaging
the unit,. Install bars between lifting
straps. This will prevent the straps
from crushing the unit cabinet or
damaging the unit finish.
