Step 6 — Install Accessories —
sories are available to provide the following optional features
(for details, refer to the Controls, Start-Up, Operation, Service
and Troubleshooting guide shipped with the unit).
ENERGY MANAGEMENT MODULE — The energy man-
agement module (EMM) is used for any of the following types
of temperature reset, demand limit and ice features:
• 4 to 20 mA inputs for cooling set point reset and capacity
limit (requires field-supplied 4 to 20 mA generator)
• 0 to 10 v output for percentage total capacity running
• 24 v discrete outputs for shutdown and running relays
• 10k space temperature input
The EMM provides discrete inputs for occupancy override,
demand limit switch 2 (step 1 demand limit is wired to the
base board, requires field-supplied dry contacts), remote
lockout switch, and ice done switch (requires field-supplied
dry contacts).
UNIT SECURITY/PROTECTION ACCESSORIES — For
applications with unique security and/or protection require-
ments, several options are available for unit protection.
Security grilles and hail guards are available. Contact your
local Carrier representative for more details. For installation
details, refer to separate installation instructions supplied with
the accessory package.
COMMUNICATION ACCESSORIES — A number of com-
munication options are available to meet any requirement.
Contact your local Carrier representative for more details. For
installation details, refer to separate installation instructions
supplied with the accessory package.
SERVICE OPTIONS — A ground fault convenience outlet
(GFI-CO) accessory is available to aid in servicing 30XV units
with Greenspeed intelligence. The GFI-CO is a convenience
outlet with a 5-amp GFI receptacle.
Contact your local Carrier representative for more details. For
installation details, refer to separate installation instructions
supplied with the accessory package.
Step 7 — Leak Test Unit —
Greenspeed ® intelligence is shipped with a complete operating
charge of R-134a and should be under sufficient pressure to
conduct a leak test.
A number of acces-

Perform a leak test to ensure that leaks have not developed
during unit shipment. Dehydration of the system is not
required unless the entire refrigerant charge has been lost.
There are several O-ring face seal fittings utilized in the oil
line piping. If a leak is detected at any of these fittings, open
the system and inspect the O-ring surface for foreign matter or
damage. Do not re-use O-rings. Repair any leak found follow-
ing good refrigeration practices.
CAUTION
DO NOT OVERTIGHTEN THESE O-RING FACE
SEAL FITTINGS. Over-tightening will result in O-ring
damage and a potential refrigerant leak.
Refer to the Controls, Start-Up, Operation, Service and Trou-
bleshooting manual for additional information.
DEHYDRATION — Refer to Carrier Standard Service Tech-
niques Manual, Chapter 1, Refrigerants, Sections 6 and 7 for
details. Do not use compressor to evacuate system.
REFRIGERANT CHARGE — The 30XV chiller with Green-
speed intelligence is shipped from the factory with a full
charge of R-134a. The unit should not need to be charged at
installation unless a leak was detected in Leak Test Unit sec-
tion. If dehydration and recharging is necessary, use industry
standard practices or refer to Carrier Standard Service Tech-
niques Manual as required.
IMPORTANT: These units are designed for use with
R-134a only. DO NOT USE ANY OTHER refrigerant
in these units.
CAUTION
When evacuating or charging, circulate water through the
evaporator at all times to prevent freezing and a potential
refrigerant leak. Failure to follow this procedure will
impact or otherwise negatively affect the warranty should
damage result from freezing.
CAUTION
DO NOT OVERCHARGE system. Overcharging results
in higher discharge pressure with higher power consump-
tion and possible compressor damage.
