Installation Instructions
SAFETY CONSIDERATIONS
Absorption liquid chillers provide safe and reliable
service when operated within design specifica-
tions.Whenoperatingthisequipment,usegoodjudg-
ment and safety precautions to avoid damage to
equipment and property or injury to personnel.
Be sure you understand and follow the procedures
and safety precautions contained in the chiller in-
structions as well as those listed in this guide.
DO NOT USE OXYGEN or air to purge lines, leak test, or
pressurize a chiller. Use nitrogen.
NEVER EXCEED specified test pressures. For the 16JT chiller,
the maximum pressure is 12 psig (83 kPa).
WEAR goggles and suitable protective clothing when han-
dling lithium bromide, octyl alcohol, inhibitor, lithium hy-
droxide, and hydrobromic acid. IMMEDIATELY wash any
spills from the skin with soap and water. IMMEDIATELY
FLUSH EYES with water and consult a physician.
DO NOT USE eyebolts or eyebolt holes to rig chiller sec-
tions or the entire assembly.
DO NOT work on high-voltage equipment unless you are a
qualified electrician.
DO NOT WORK ON electrical components, including con-
trol panels or switches, until you are sure ALL POWER IS
OFF and no residual voltage can leak from capacitors or solid-
state components.
LOCK OPEN AND TAG electrical circuits during servic-
ing. IF WORK IS INTERRUPTED, confirm that all circuits
are deenergized before resuming work.
NEVER DISCONNECT safety devices or bypass electric in-
terlocks while operating the chiller. Also, never operate the
chiller when any safety devices are not adjusted and func-
tioning normally.
DO NOT syphon lithium bromide or any other chemical by
mouth.
BE SURE all hydrogen has been exhausted before cutting
into purge chambers. Hydrogen mixed with air can explode
when ignited.
WHEN FLAMECUTTING OR WELDING on an absorp-
tion chiller, some noxious fumes may be produced. Ventilate
the area thoroughly to avoid breathing concentrated fumes.
DO NOT perform any welding or flamecutting to a chiller
while it is under a vacuum or pressurized condition.
NEVER APPLY an open flame or live steam to a refrigerant
cylinder. Dangerous overpressure can result. When neces-
sary to heat a cylinder, use only warm (110 F [43 C]) water.
DO NOT REUSE disposable (nonreturnable) cylinders or at-
tempt to refill them. It is DANGEROUS AND ILLEGAL.
When cylinder is emptied, evacuate remaining gas pressure,
loosen the collar, and unscrew and discard the valve stem.
DO NOT INCINERATE.
DO NOT ATTEMPT TO REMOVE fittings, covers, etc.,
while the chiller is under pressure or while chiller is
running.
DO NOT climb over a chiller. Use platform, catwalk, or stag-
ing. Follow safe practices when using ladders.
DO NOT STEP ON chiller piping. It might break or bend
and cause personal injury.
USE MECHANICAL EQUIPMENT (crane, hoist, etc.) to
lift or move inspection covers or other heavy components.
Even if components are light, use such equipment when there
is a risk of slipping or losing your balance.
VALVE OFF AND TAG steam, water, or brine lines before
opening them.
DO NOT LOOSEN waterbox cover bolts until the water box
has been completely drained.
DO NOT VENT OR DRAIN waterboxes containing indus-
trial brines, liquid, gases, or semisolids without permission
from your process control group.
BE AWARE that certain automatic start arrangements can
engage starters. Open the disconnects ahead of the starters
in addition to shutting off the chiller or pump.
USE only repaired or replacement parts that meet the code
requirements of the original equipment.
DO NOTALLOW UNAUTHORIZED PERSONS to tamper
with chiller safeties or to make major repairs.
PERIODICALLY INSPECT all valves, fittings, piping, and
relief devices for corrosion, rust, leaks, or damage.
PROVIDE A DRAIN connection in the vent line near each
pressure relief device to prevent a build-up of condensate or
rain water.
IMMEDIATELY wipe or flush the floor if lithium bromide
or octyl alcohol is spilled on it.

INTRODUCTION
General — The 16JT chiller is factory assembled, wired,
and leak tested. Installation (not by Carrier) consists prima-
rily of establishing water, steam, and electrical services to
the chiller. Rigging, installation, insulation, field wiring, and
field piping are the responsibility of the contractor and/or
customer. Carrier has no installation responsibilities for the
equipment.
Job Data — Necessary information consists of chiller lo-
cation drawings, piping drawings, field wiring diagrams, and
a rigging guide.
RECEIVING THE CHIILLER
Identify Chiller — The chiller model number and serial
number are stamped on the chiller identification plate. Check
this information against shipping papers and job data. For
information on model number nomenclature, see Fig. 1.
The 16JT comes with either electro-mechanical controls
or Product Integrated Controls (PIC), depending on when it
was manufactured.
If the last five digits of the serial number are 80XXX (where
XXX stands for the last three digits of the serial number),
the model comes with fusible plug drain piping and rupture
disc piping; if the last five digits are 92XXX, the model comes
with rupture disc piping only.
For 16JT chillers sizes 810 to 880, the evaporator and ab-
sorber are located side by side; for sizes 080 to 150 and 080L
to 150L, the evaporator is located above the absorber.
Inspect Shipment (Fig. 2) — One-piece chillers are
at a deep vacuum when shipped. Do not open any valves
until the vacuum has been noted. Refer to One-Piece Chill-
ers: Check Shipping Vacuum below.
NOTE: Chillers shipped in 2 pieces are under nitrogen
pressure.
Inspect for shipping damage while chiller is still on ship-
ping conveyance. If chiller appears to be damaged or has
been torn loose from its anchorage, have it examined by trans-
portation inspectors before removal. Forward claim papers
directly to transportation company. Manufacturer is not re-
sponsible for any damage incurred in transit.
Check all items against shipping list. Immediately notify
the nearest Carrier Air Conditioning office if any item is
missing.
To prevent loss or damage, leave all parts in original pack-
ages until installation.
One-Piece Chillers: Check Shipping Vacuum —
To check for leaks that have occurred during shipment on
one-piece chillers:
1. Connect an absolute pressure gage to a service valve.
2. Record the absolute pressure of the assembly. If the ves-
sel pressure is greater than 0.28 in. (7 mm) of mercury,
the chiller has acquired a leak in shipping and must be
leak tested. Refer to the Chiller Leak Test section for
instructions.
Two-Piece Chillers: Check Shipping Pressure
—To check for leaks that have occurred during shipment
on two-piece chillers:
1. Connect a pressure gage (30 psig [200 kPa]) to a service
valve on each piece. Two-piece chillers are pressurized
with nitrogen to 5 psig (34 kPa).
2. If the vessel has lost its pressure, it has acquired a leak
during shipping and must be leak tested after positioning
and assembly. Refer to the Chiller Leak Test section for
instructions.
Provide Chiller Protection — If the chiller will not
be installed immediately, it is very important to use a drop
cloth or plastic cover to protect the chiller from construction
dirt and moisture before installation.Also, do not remove pro-
tective shipping cover on control panel until ready to use.

RIGGING AND POSITIONING
Rigging procedures vary depending on whether the chiller
is shipped in one or 2 pieces.
Lifting the chiller from points other than those specified
may result in serious damage and personal injury. Rig-
ging equipment and procedures must be adequate for
chiller weights and sizes. Refer to Tables 1 and 2 for
chiller weights, and Fig. 3 and 4 for overall dimensions.
Rig One-Piece Units (Fig. 5) — Lift the entire as-
sembly with cable slings placed under the lower shell, as
shown in Fig. 5, to distribute and balance the weight.
Rig Two-Piece Units (Fig. 6)
If the chiller is assembled before it is rigged, to avoid
damage to the chiller, do not lift under the generator
shell or waterboxes. The chiller should be lifted under
the absorber-evaporator shell.
PREPARATION — Two-piece units must be prepared for
installation before they can be rigged. Refer to Fig. 7-10.
1. Open the auxiliary evacuation valves to relieve pressure
in the absorber-evaporator shell.
2. Open the shipping valve on the generator-condenser as-
sembly to relieve pressure.
To keep foreign particles out of the chiller, do not leave
chiller open any longer than necessary.
Do not remove any stock from pipe ends. Do not get
slag inside chiller while flamecutting.
3. Remove all piping end plates by flamecutting the end plate,
and weld the flange around each outer diameter as shown
in Fig. 7. Cut these pieces, as shown in Fig. 8, for proper
reconnection.
4. Grind the cut pieces smooth for a close fit when the chiller
pieces are assembled.
