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.

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.

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)

•

in. strain relief (2)

• 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)

Table 1 — Accessory Package Usage

Be sure power to equipment is shut off before performing

maintenance or service. Lock out and safety-tag all

disconnects.

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.
