Centrifugal Fan Air-Cooled Condenser
Installation Instructions
09FA
INTRODUCTION
The 09FA Centrifugal Air-Cooled Condensers
are designed for indoor installations. If outdoor
installation is desired, a weather enclosure must be
constructed around the unit.
UNIT LOCATION
Allow sufficient clearance for:
1. Removal of fan shaft and coil.
2. Service of fan motor, bearings, damper motor
and linkage (at least 30 inches)
3. Unit air supply (minimum distance of 4 feet
from ceiling, wall, or floor when supplied from
one side only).
PRE-INSTALLATION
1 File claim with shipping company if shipment is
damaged or incomplete.
2. Examine unit nameplate to verify that electrical
requirements match available power supply.
3. Rotate fans by hand. Check for freedom of
rotation and secureness to fan shaft.
4. Remove shipping straps from skid and unit.
INSTALLATION
Observe the following-
1. When rigging, do not support unit weight by
fan shaft extension or coil connections Put
rigging medium completely around unit, using
spreader bars to ensure that sling lifts at the
skid without touching the unit sides.
2. Remove coil piping connection protective caps
only when ready to connect piping.
3. Exercise reasonable care not to bend or muti
late coil fins.
4. On bypass units, where bypass is not desired,
block off opening with a strip of sheet metal
(field-supplied) and secure.

2. Bolt suspension clips (supplied), one near each
corner of fan section and one near each end of
coil section. Tighten bolts (supplied) securely.
3. Lift unit into position.
4. Pass threaded hanger rod (field-supplied) thru
each suspension clip.
5. Fasten with nuts (field-supplied).
VERTICAL ARRANGEMENT
1. Bolt legs (accessory) to inlet side of coil
section, using 5/8 in. - 11 captive nuts (located
on inward flanges of coil section) and bolts
(supplied). Tighten securely.
2. Rotate motor end bells 90 degrees so drain
holes are at bottom. Rotating end bells must be
performed by an authorized vendor’s motor
repair shop.
Refrigerant Piping
GENERAL — All field leak and pressure testing
should be in accordance with local code require
ments. If no local code exists, use American
Standard Safety Code for Mechanical Refrigeration
(A.S.A. B9.1).
Eor leak testing procedures, refer to the Carrier
Standard Service Techniques Manual, Chapter 1,
Section 1-6.
Refrigerant line sizing depends on length of
lines between various sections of the refrigerant
system. Consider the amount of liquid lift and
drop in the system as well as proper compressor oil
return. Consult Carrier System Design Manual, Part
3, for proper piping sizes and design.
Liquid and hot gas connections for any one
split are same size so coil may be reversed for
opposite-hand connection, but must be piped for
counter flow in any case.
LIQUID SHUT-OEF VALVE AND SIGHT GLASS
— Shut-off valve is not supplied with units. It is
strongly recommended that a full line size liquid
shut-off valve be field supplied near condenser to
allow for servicing parts of the refrigerant circuit.
A field-supplied, moisture-indicating sight glass is
recommended for use in charging and servicing the
system. Refer to Fig. 2 for location.
The American Standard Safety Code for
Mechanical Refrigeration (A.S.A. B9.1, 1964, para
graph 12.1) states as follows: “Every refrigerating
system shall be protected by a pressure relief
device unless so constructed that the pressures due
to fire conditions will be safely relieved by some
part of the system.” Since the 09FA units have no
pressure relief device, it should be field supplied
and installed. When the split coil is used with
multiple systems, each system must have a pressure
relief.
COIL CONNECTIONS - Refer to Eig. 2, 3. Make
connections.
