The long-standing Engineering sym-

bol for efficiency, η, is now Carrier’s
symbol for air-cooled chiller efficiency.
The standard efficiency ECOLOGIC
and high efficiency ECOLOGIC η
30GXN,R air-cooled chillers are
designed from the ground up to meet
the needs of today and tomorrow.

Features/Benefits
Easy installation
The 30GXN,R unit has a compact
design that is up to 50% smaller than
earlier air-cooled chillers. The compact
footprint can yield substantial installa-
tion savings by requiring less structural
steel, concrete, security fencing or
architectural screening. The 30GXN,R
unit is delivered as a complete package
for easy installation.
A quick start-up is assured once
installation is complete, since each
30GXN,R unit is manufactured at an
ISO 9001:2000 listed manufacturing
facility to ensure quality. In addition, all
units are factory run tested under full
load to provide reliable start-up.
Easy to live with
The 30GXN,R units have a quiet, low-
vibration design featuring rotary screw
compression and AeroAcoustic™ fans
that reduce sound levels and
improve sound quality. Lower sound
levels help avoid the need for costly
sound barriers that may be needed
with other screw compressor chillers.
The 30GXN,R controls are fully auto-
matic. The leaving-fluid temperature is
directly controlled, and the entering-
fluid temperature is continuously
monitored to detect load and flow
changes. This combination (an exclu-
sive ComfortLink controls advantage)
provides the most precise temperature

LEGEND Determine maximum deviation from average voltage:

ICF — Maximum Instantaneous Current Flow (AB) 243 – 239 = 4 v
MCA — Minimum Circuit Ampacity (for wire sizing) (BC) 239 – 236 = 3 v
MOCP — Maximum Overcurrent Protection (AC) 239 – 238 = 1 v
Rec Fuse Size — Recommended Dual-Element Fuse Amps (150% of largest Maximum deviation is 4 v. Determine percent voltage imbalance:
compressor rated load amps [RLA] plus 100% of remaining 4
compressor RLAs and sum of condenser fan full load amps % Voltage Imbalance = 100 x
[FLAs]. Choose next largest standard fuse size.) 239
WD — Wye-Delta Start = 1.7%
XL — Across-the-Line Start
This amount of phase imbalance is satisfactory as it is below the maximum allowable 2%.
*Circuit A/Circuit B.
†Wye-delta start is standard. Across-the-line start is not available.
**Amperages in ( ) are for units with cooler heaters installed. IMPORTANT: Contact your local electric utility company immediately if the supply
voltage phase imbalance is more than 2%.
NOTES:
1. Main power must be supplied from a field-supplied fused electrical service with a (factory or
field-installed) disconnect located in sight from the unit.
2. Cooler heater, oil heater, and control circuit power must be supplied from a separate source
through a field-supplied disconnect. The control circuit power transformer accessory may be
applied to power from the main unit power supply.
3. Maximum incoming wire size for each terminal block is 500 kcmil.
4. Maximum allowable supply voltage phase imbalance is voltage 2%.
5. Never operate a motor where a phase imbalance in supply voltage is greater than 2%. Use
the following formula to determine the percent voltage imbalance.
Percent Voltage Imbalance
max voltage deviation from average voltage
= 100 x
average voltage
Example: Supply voltage is 240-3-60.
AB = 243 v
BC = 236 v
AC = 238 v
243 + 236 + 238
Average voltage =
3
= 239 v

LEGEND Determine maximum deviation from average voltage:

ICF — Maximum Instantaneous Current Flow (AB) 243 – 239 = 4 v
MCA — Minimum Circuit Ampacity (for wire sizing) (BC) 239 – 236 = 3 v
MOCP — Maximum Overcurrent Protection (AC) 239 – 238 = 1 v
Rec Fuse Size — Recommended Dual-Element Fuse Amps (150% of largest Maximum deviation is 4 v. Determine percent voltage imbalance:
compressor rated load amps [RLA] plus 100% of remaining 4
compressor RLAs and sum of condenser fan full load amps % Voltage Imbalance = 100 x
[FLAs]. Choose next largest standard fuse size.) 239
WD — Wye-Delta Start = 1.7%
XL — Across-the-Line Start
This amount of phase imbalance is satisfactory as it is below the maximum allowable 2%.
*Circuit A/Circuit B.
†Wye-delta start is standard. Across-the-line start is not available. IMPORTANT: Contact your local electric utility company immediately if the supply
**Amperages in ( ) are for units with cooler heaters installed. voltage phase imbalance is more than 2%.
NOTES:
1. Main power must be supplied from a field-supplied fused electrical service with a (factory or
field-installed) disconnect located in sight from the unit.
2. Cooler heater, oil heater, and control circuit power must be supplied from a separate source
through a field-supplied disconnect. The control circuit power transformer accessory may be
applied to power from the main unit power supply.
3. Maximum incoming wire size for each terminal block is 500 kcmil.
4. Maximum allowable supply voltage phase imbalance is voltage 2%.
5. Never operate a motor where a phase imbalance in supply voltage is greater than 2%. Use
the following formula to determine the percent voltage imbalance.
Percent Voltage Imbalance

Example: Supply voltage is 240-3-60.
AB = 243 v
BC = 236 v
AC = 238 v

LEGEND Determine maximum deviation from average voltage:

ICF — Maximum Instantaneous Current Flow (AB) 243 – 239 = 4 v
MCA — Minimum Circuit Ampacity (for wire sizing) (BC) 239 – 236 = 3 v
MOCP — Maximum Overcurrent Protection (AC) 239 – 238 = 1 v
Rec Fuse Size — Recommended Dual-Element Fuse Amps (150% of largest Maximum deviation is 4 v. Determine percent voltage imbalance:
compressor rated load amps [RLA] plus 100% of remaining 4
compressor RLAs and sum of condenser fan full load amps % Voltage Imbalance = 100 x
[FLAs]. Choose next largest standard fuse size.) 239
WD — Wye-Delta Start = 1.7%
XL — Across-the-Line Start
This amount of phase imbalance is satisfactory as it is below the maximum allowable 2%.
*Circuit A/Circuit B.
†Wye-delta start is standard. Across-the-line start is not available.
**Amperages in ( ) are for units with cooler heaters installed. IMPORTANT: Contact your local electric utility company immediately if the supply
voltage phase imbalance is more than 2%.
NOTES:
1. Main power must be supplied from a field-supplied fused electrical service with a (factory or
field-installed) disconnect located in sight from the unit.
2. Cooler heater, oil heater, and control circuit power must be supplied from a separate source
through a field-supplied disconnect. The control circuit power transformer accessory may be
applied to power from the main unit power supply.
3. Maximum incoming wire size for each terminal block is 500 kcmil.
4. Maximum allowable supply voltage phase imbalance is voltage 2%.
5. Never operate a motor where a phase imbalance in supply voltage is greater than 2%. Use
the following formula to determine the percent voltage imbalance.
Percent Voltage Imbalance
max voltage deviation from average voltage
= 100 x
average voltage
Example: Supply voltage is 240-3-60.
AB = 243 v
BC = 236 v
AC = 238 v
243 + 236 + 238
Average voltage =
3
= 239 v

NOTES:
1. Main power must be supplied from a field-supplied fused electrical service with a (factory or
field-installed) disconnect located in sight from the unit.
2. Cooler heater, oil heater, and control circuit power must be supplied from a separate source
through a field-supplied disconnect. The control circuit power transformer accessory may be
applied to power from the main unit power supply.
3. Maximum incoming wire size for each terminal block is 500 kcmil.
