Installation Instructions
Part No. 30GT911050
50/60 Hz
SAFETY CONSIDERATIONS
Installation of this accessory can be hazardous due to system pressures, electrical components, and equipment location
(such as a roof, or elevated structure).
Only trained, qualified installers and service technicians
should install, start up, and service this equipment.
When installing this accessory, observe precautions in the
literature and on any labels attached to the equipment, and all
other safety precautions that may apply.
• Follow all safety codes.
• Wear safety glasses and work gloves.
• Use care in handling and installing this accessory.
ELECTRIC SHOCK HAZARD
To avoid the possibility of electrical shock,
open and tag all remote disconnects before
installing this equipment.
INTRODUCTION
The remote cooler mounting accessory permits indoor relocation of the cooler from 30GTN, GTR, G UN, GUR units up
to 75 ft (22 m) away from the base unit. Relocating the cooler
introduces minimal line losses if correct piping practices are
followed. See Table 1 for the number of accessory packages required for each unit and for the package contents.
In addition to the parts supplied with the accessory package,
the following material must be field-supplied:
• refrigerant-grade liquid and suction line piping (length
determined by installation). See Table 2 for connection
sizes.
• pressure relief valves and fittings
• suction flange gasket
• suction line tubing insulation (length determined by
installation)
5
•
/8-in. strain relief
• conduit (length determined by installation)

INSTALLATION
1. Inspect package contents for any missing or damaged
parts. File a claim with the shipping agency if parts are
damaged. Notify your Carrier representative if any
item is missing.
2. Determine the new location for the cooler(s). Ensure
that the new location supports the cooler weight and
that there is enough room for service access and tube
removal. See Table 1 to determine the model numbers
and quantities of coolers in each unit. See Table 3 for
cooler weights and Fig. 1 for cooler dimensions.
NOTE: Steps 3-20 below describe how to relocate and
reinstall one cooler. For units with two coolers, perform these for each cooler.

enough room to install the EXV or TXV (if used),
sight glass, filter drier, and service valve. See Fig. 2.
Also ensure that there is sufficient room to remove
cooler tubes if required for future service.
New cooler location and supporting structures must be able
to support the weight of the filled cooler.
6. At the base unit control box, (see Fig. 3) disconnect
the other ends of the thermistor leads; make sure to
label the leads. If applicable, disconnect the other ends
of the EXV cables that came with the unit and discard
them.
7. At the base unit, remove the liqui d li n e pi ping bet ween
the manual shutoffs and the old cooler conections. The
piping includes EXVs or TXVs, sight glasses, and filter driers. See Fig. 2.
8. Reinstall the piping at the cooler; install the shutoff
valves (supplied with the accessory) immediately
upstream from the filter driers. See Fig. 2.
9. Following Carrier-recommended piping practices,
install additional field-supplied liquid line piping in
the required lengths to reconnect the cooler and base
unit. As shown in Fig. 2, the new liquid lines between
the service valves must each have a field-supplied and
installed pressure relief valve.
3. Open and tag all electrical disconnects.
4. Remove the cooler from the base unit, following the
directions in the base unit Installation, Start-up and
Service Instructions. If required, strip back the insulation on the cooler tube sheets and use the 2 large holes
in the top corners of the tube sheets for lifting. Make
sure to label the thermistors with corresponding thermistor numbers for reinstallation. For u nits with electronic expansion valves (EXVs), disconnect the
electrical cables from the EXVs. For units with thermostatic expansion valves (TXVs); note the locations
of the equalizer lines and sensor bulbs and detach
them.
5. Transport the cooler to its new location, and bolt it in
position according to the instructions for replacing a
cooler in the base unit Installation, Start-Up and Service Instructions. Make sure the new location has
Do not shut off both service valves in either liquid line.
Pressure can build within the trapped area. To avoid the
possibility of personal injury or property damage, a fieldsupplied pressure relief valve must be installed in each liquid line between the two shutoff valves. See Fig. 2.
10. Following Carrier-recommended piping practices,
replace the suction flange gaskets and install additional
field-supplied suction line piping in the required
lengths to reconnect the cooler and bas e unit. For units
with TXVs: Replace the sensor bulbs and equalizer
lines according to their original positioning. Make sure
to insulate the TXV bulbs.
11. Following the instructions for replacing a cooler in the
base unit Installation, S tart-up an d S ervice in struction ,
reinstall the thermistors in the cooler.
