SAFETY CONSIDERATIONS
Installing, starting up, and servicing this equipment can be hazard-
ous due to system pressures, electrical components, and equip-
ment location. Only trained, qualified installers and service me-
chanics should install, start up, and service this equipment.
When working on the equipment, observe precautions in the liter-
ature, and on tags, stickers, and labels attached to the equipment.
• Follow all safety codes.
• Wear safety glasses and work gloves.
• Use care in handling, rigging, and setting bulky equipment.
WARNING
DO NOT USE TORCH to remove any component. System
contains oil and refrigerant under pressure.
To remove a component, wear protective gloves and goggles
and proceed as follows:
a. Shut off electrical power to unit.
b. Recover refrigerant to relieve all pressure from system
using both high-pressure and low pressure ports.
c. Traces of vapor should be displaced with nitrogen and
the work area should be well ventilated. Refrigerant in
contact with an open flame produces toxic gases.
d. Cut component connection tubing with tubing cutter and
remove component from unit. Use a pan to catch any oil
that may come out of the lines and as a gage for how
much oil to add to the system.
e. Carefully un-sweat remaining tubing stubs when neces-
sary. Oil can ignite when exposed to torch flame.
Failure to follow these procedures may result in personal inju-
ry or death.
WARNING
Electrical shock can cause personal injury and death. Shut off
all power to this equipment during installation. There may be
more than one disconnect switch. Tag all disconnect locations
to alert others not to restore power until work is completed.

30XA080-501
Air-Cooled Liquid Chillers

INTRODUCTION
These instructions cover installation of 30XA080-501 air-
cooled liquid chillers with electronic controls and units with
factory-installed options (FIOPs). See Fig. 1.
INSTALLATION
Storage
If the unit is to be stored for a period of time before installation or
start-up, be sure to protect the machine from construction dirt.
Keep protective shipping covers in place until the machine is
ready for installation.
Step 1 — Inspect Shipment
Inspect unit for damage upon arrival. If damage is found, immedi-
ately file a claim with the shipping company, and contact your lo-
cal Carrier representative.
Step 2 — Place, Mount, and Rig the Unit
When considering a location for the unit, be sure to consult NEC
(National Electrical Code, U.S.A.) and/or local code requirements.
Allow sufficient space for airflow, wiring, piping, and service. See
Fig. 2-23.
NOTE: To facilitate refrigerant vent piping, all units have fusible
plugs with 1/4 in. SAE (Society of Automotive Engineers) flares
and pressure reliefs with 3/4 in. NPT fittings (if required by local
codes).
NOTE: The 30XA501 units are shipped as two separate pieces re-
ferred to as the 501A module (section including cooler and com-
pressors), referred to on the unit nameplate as 30XAB50A, and
the 501B module, referred to on the unit nameplate as
30XAB50B. These two pieces must be field combined prior to in-
stalling cooler piping and electrical connections (see the section
30XA501 Unit Assembly on page 88).
PLACING UNIT
Locate the unit so that the condenser airflow is unrestricted
both above and on the sides of the unit. Airflow and service
clearances are 6 ft (1.8 m) around the unit. Acceptable clear-
ance on the sides or ends without control boxes can be reduced
to 3 ft (1 m) without sacrificing performance as long as the re-
maining three sides are unrestricted. Acceptable clearance on
the side with a control box can be reduced to 4 ft (1.3 m) due to
NEC regulations, without sacrificing performance as long as
the remaining three sides are unrestricted. Provide ample room
for servicing and removing the cooler. See Fig. 2-23 for re-
quired clearances. Local codes for clearances take precedence
over the manufacturer’s recommendations when local codes
call for greater clearances. Units are suitable for outdoor use
only.
If multiple units are installed at the same site, a minimum separa-
tion of 10 ft (3 m) between the sides of the machines is required to
maintain proper airflow and minimize the chances of condenser
air recirculation.
MOUNTING UNIT
The unit may be mounted on a level pad directly on the base rails,
on a raised mounting rail around the unit, or on vibration isolation
springs. For all units, ensure placement area is strong enough to
support unit operating weight. See Tables 1-8. Mounting holes are
provided for securing the unit to the pad, mounting rail or vibra-
tion isolation springs. Bolt the unit securely to pad or rails. If vi-
bration isolators (field-supplied) are required for a particular in-
stallation, refer to unit weight distribution in Fig. 24-26 to aid in
the proper selection of isolators. The 30XA units can be mounted
directly on spring isolators. Once installed, the unit must be level
to within 1/8-in. per ft (1 cm per meter) along the long axis of the
oil separator. This is required for oil return to the compressor(s).
CAUTION
DO NOT re-use compressor oil or any oil that has been ex-
posed to the atmosphere. Dispose of oil per local codes and
regulations. DO NOT leave refrigerant system open to air any
longer than the actual time required to service the equipment.
Seal circuits being serviced and charge with dry nitrogen to
prevent oil contamination when timely repairs cannot be com-
pleted. Failure to follow these procedures may result in dam-
age to equipment.
IMPORTANT: This equipment generates, uses, and can radiate
radio frequency energy and if not installed and used in accor-
dance with these instructions may cause radio interference. It has
been tested and found to comply with the limits of a Class A
computing device as defined by FCC (Federal Communications
Commission, U.S.A.) regulations, Subpart J of Part 15, which
are designed to provide reasonable protection against such inter-
ference when operated in a commercial environment.
