SAFETY CONSIDERATIONS
Installing, starting up, and servicing air-conditioning
equipment can be hazardous due to system pressures, electrical
components, and equipment location. Only trained, qualified
installers and service technicians should install, start-up, and
service this equipment.
When working on air-conditioning equipment, observe
precautions in the literature and on tags, stickers, and labels
attached to the equipment. Follow all safety codes. Wear safety
glasses and work gloves. Use care in handling equipment.
Be sure power to equipment is shut off before performing
maintenance or service. Lock out and safety-tag all
disconnects.
GENERAL
The remote cooler accessory allows for the indoor reloca-
tion of the cooler on 30XA080-350 units as another means of
freeze protection. When the cooler is located in a heated space,
an anti-freeze solution is not needed and the performance
degradation associated with antifreeze solution can be avoided.
Maximum separation of the 30XA base unit and cooler is
limited to 50 lineal ft (15.25 m) or 75 equivalent ft (22 m) of
piping. For more information, refer to the Carrier Piping De-
sign manual.
The liquid and economizer lines between the exterior-
installed unit and the remote, interior-installed cooler must
have pressure relief devices installed in accordance with
ASHRAE 15 (American Society of Heating, Refrigeration, and
Air Conditioning Engineers) and local codes.
Units to be modified for a remote cooler application must
have the following options:
• Factory-installed suction service valve option.
• Condenser coil type:
— Aluminum fin and copper tube
— Pre-coat aluminum fin and copper tube
— E-coat aluminum fin and copper tube
— Copper fin and copper tube
— E-coat copper fin and copper tube
NOTE: The microchannel heat exchanger option can NOT use
the remote cooler accessory.
Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.

Installation Instructions

Printed in U.S.A.
Remote Cooler Accessory
The application is limited to the following constraints:
• Operating chilled water temperature is between 40 and 55 F
(4.4 and 12.8 C). When the remote cooler is applied, the
cooler heaters will not function, so it is critical to maintain the
water temperature above the freezing point at all times. If the
water temperature falls below the freezing point, the cooler
does not have protection to keep the water from freezing.
• The interior space temperature where the cooler will be
installed must be maintained at a minimum of 50 F (10 C).
• Underground refrigerant piping is NOT permitted for this
application.
See Table 1 for accessory package usage and see Table 2 for
accessory package contents. In addition to the parts supplied
with each accessory package, the following material must be
field-supplied:
• Refrigerant grade liquid and suction line copper piping for
30XA080-120: circuits A and B and 30XA140-160: circuit
B (length determined by installation). See Tables 3A and 3B
for pipe sizes.
• Schedule 40 steel pipe for 30XA140-160: circuit A and
30XA180-350: circuits A and B (length determined by
installation). See Tables 3A and 3B for pipe sizes.
• 350 psig pressure relief valves and fittings (2 per circuit)
• Suction line tubing insulation (length determined by
installation)
• Economizer line tubing insulation (length determined by
installation)

• Conduit (length determined by installation)
• ASME (American Society of Mechanical Engineers) B16.9
stub end (4 in. [102 mm]), Schedule 40 Steel (one needed
for 30XA140-160, two needed for 30XA180-350)
• ASME B16.5 Class 600 pipe flange (4 in. [102 mm]) with
field-modified extra mounting hole (one needed for
30XA260-300, two needed for 325, 350)
• Flange mounting hardware
• Extra flange gaskets (if necessary)
The 30XA units use R-134a refrigerant. No other refriger-
ant may be used in this system. Suction tubing design pres-
sure is 220 psig (1517 kPa). Economizer and liquid tubing
design pressure is 350 psig (2413 kPa). Failure to use gage
set, hoses, and recovery systems designed to handle
R-134a refrigerant may result in personal injury and equip-
ment damage. If unsure about equipment, consult the
equipment manufacturer.
