INTRODUCTION

These instructions cover installation of 30XV140-500 air-
cooled liquid chillers with Greenspeed
tronic controls, and units with factory-installed options
(FIOPs). See Fig. 1.

INSTALLATION

If the unit is to be stored for a period of time be-
Storage —
fore 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. Follow these
storage guidelines:
• Store the unit in a clean and dry location.
• Avoid contamination.
• Maintain storage temperature of –13 to 149°F (–25 to
65°C).
• Before applying power, perform complete physical
inspection. Check for carbon deposits inside drive,
burned or damaged components, and blown fuses.
• The unit can be stored for 3 years maximum without
power. If the unit is stored for long periods of time with-
out use, special procedures must be performed to ensure
the safe and efficient operation of the VFD capacitor
banks. If the unit has been stored for more than 3 years
without power applied to the drives, contact Carrier Ser-
vice to obtain information and instructions for reforming
the capacitor banks.
• Perform a static test before applying power.
• Ensure a proper operating environment before applying
power: clean and dry; 5 to 100% humidity, non-condens-
ing; maximum temperature 126°F (52°C). If the tem-
perature is below 14°F (–10°C), the drive must be started
with 50% load for 10 minutes.
• When removing from storage, apply power for 3 to 4
hours to exercise capacitors.
Step 1 — Inspect Shipment —
age upon arrival. If damage is found, immediately file a claim
with the shipping company, and contact your local 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, pip-

NOTE: To facilitate refrigerant vent piping, all units have fus-

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 clearance on the sides or ends without
control boxes or VFDs can be reduced to 3 ft (1 m) without
sacrificing performance as long as the remaining three sides
are unrestricted. Acceptable clearance on the side with a
control box or VFD 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 evaporator. See Fig. 2-
20 for required clearances. Local codes for clearances take
precedence over the manufacturer's recommendations when
local codes call for greater clearances.
If multiple units are installed at the same site, a minimum sepa-
ration 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 Table 1. Mounting holes are pro-
vided for securing the unit to the pad, mounting rail or vi-
bration isolation springs. Bolt the unit securely to pad or
rails. If vibration isolators (field-supplied) are required for a
particular installation, refer to unit weight distribution in
Fig. 23 to aid in the proper selection of isolators. Once in-
stalled, the unit must be level to within
per meter) along the long axis of the unit. This is required
for oil return to the compressor(s). For more details about
physical data, see Tables 2 and 3.
NOTE: For units that are point loaded, such as those using rub-
ber and shear isolators, the base rail must be supported with a
24 x 4 in. (610 x 102 mm) plate at each mounting location, or
base rail deflection may result. Fasten the unit to the plates
using the mounting holes.
