SAFETY CONSIDERATIONS
Absorption liquid chiller/heaters provide safe and reliable
service when operated within design specifications. When
operating this equipment, use good judgment and safety precautions to avoid damage to equipment and property or injury to personnel.
Be sure you understand and follow theproceduresandsafety
precautions contained in the machine instructions as well as
those listed in this guide.
DO NOT USE OXYGEN or air to purge lines, leak test, or
pressurize a machine. Use nitrogen.
NEVER EXCEED specified testpressures.Forthe16DF machine, the maximum pressure is 12 psig (83 kPa). For the
chilled/hot water and condensing water piping, the maximum pressure is stamped on the machine.
WEAR goggles and suitable protective clothing when handling lithium bromide, octyl alcohol, inhibitor, lithium hydroxide, 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 maching sections or the entire assembly.
DO NOT work on high-voltage equipment unless you are a
qualified electrician.
DO NOT WORK ON electrical components, including control panels or switches, until you are sure ALL POWER IS
OFF and no residual voltage can leak from capacitors or solidstate components.
LOCK OPEN AND TAG electrical circuits during servicing. IF WORK IS INTERRUPTED, confirm that all circuits
are deenergized before resuming work.
NEVER DISCONNECT safety devices or bypass electric interlocks and operate the machine. Also, never operate the
machine when any safety devices are not adjusted and functioning normally.
DO NOT REPEAT unsuccessful ignition attempts or restart
after flame failure without assurance that post-purge and prepurge have eliminated combustible gas or oil vapors from
the combustion chamber. DO NOT EVER ATTEMPT IGNITION of a burner if there is shutdown leakage of gas or
oil through the fuel shutoff valves or from the fuel lines.
DO NOT syphon lithium bromide or any other chemical by
mouth.
BE SURE all hydrogen has been exhausted before cutting
into pure chambers. Hydrogen mixed with air can explode
when ignited.
WHEN FLAMECUTTING OR WELDING on an absorption machine, some noxious fumes may be produced. Ventilate the area thoroughlyto avoid breathing concentrated fumes.

DO NOT perform any welding or flamecutting to a machine
while it is under a vacuum or pressurized condition.
NEVER APPLYan open flame or live steam to a refrigerant
cylinder.Dangerous overpressure can result. When necesary
to heat a cylinder, use only warm (110 F [43 C]) water.
DO NOT REUSE disposable (nonreturnable) cylinders or attempt to refill them. It is DANGEROUS AND ILLEGAL.
When cylinder is emptied, bleed off remaining gas pressure,
loosen the collar and unscrew and discard the valve stem.
DO NOT INCINERATE.
DO NOTA TTEMPTTOREMOVE fittings, covers, etc., while
machine is under pressure or while machine is running. DO
NOT OPERATE or pressurize a machine without all cover
plates or bolts in place.
DO NOT climb over a machine. Use platform, catwalk, or
staging. Follow safe practices when using ladders.
DO NOT STEP ON machine 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 water box cover bolt until the water box
has been completely drained.
DO NOT VENT OR DRAIN water boxes containing industrial brines, liquid, gases, or semisolids without permission
of 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 machine or pump.
INVESTIGATE THE CAUSE of flame failure or any other
safety shutdown before attempting a restart.
KEEP EYES sufficiently away from sight tubes or burner
openings, and wear a protective shield or safety glasses when
viewing a burner flame.
USE only repaired or replacement parts that meet the code
requirements of the original equipment.
DO NOTALLOWUNAUTHORIZED PERSONS to tamper
with burner equipment or machine 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.
BE SURE combustion air inlets to the equipment room are
open and clear of any blockage.
Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.

INTRODUCTION
General—
and leak tested. Installation (not by Carrier) consists primarily of establishing water, fuel, exhaust, and electrical services to the machine as well as mounting and connecting the
burner. Rigging, installation, insulation, painting, field wiring, and field piping are the responsibility of the contractor
and/or customer. Carrier has no installation responsibilities
for the equipment.
The 16DF machine is factory assembled, wired,
RECEIVING THE MACHINE AND BURNER
NOTE: The chiller/heater machine and the burner are shipped
separately from different sources.
Identify Machine and Burner — The machine and
burner model numbers and serial numbers are stamped on
machine identification plates. Check this information against
shipping papers and job data.
Inspect Shipment — (Fig. 1). Single-piece machines
are at a deep vacuum when shipped. Do not open any valves
until the vacuum has been noted. Refer to Check Shipping
Vacuum section, below. Machines shipped in 2 pieces are
under nitrogen pressure.
Inspect for shipping damage while machine and burner
are still on shipping conveyance. If either appears to be damaged or has been torn loose from its anchorage, have it examined by transportation inspectors before removal. Forward
claim papers directly to transportation company. Manufacturer is not responsible for any damage incurred in transit.
Check all items against shipping list. Immediately notify
your Carrier office if any item is missing.
To prevent loss or damage, leave all parts in original packages until installation.
Check Shipping Vacuum — To check for leaks that
have occurred during shipment on single-piece machines:
1. Connect an absolute pressure gage to a service valve.
2. Record the absolute pressure of the assembly. If vessel
pressure is greater than 0.28 in. (7 mm) of mercury, the
machine has acquired a leak in shipping, and must be leak
tested. Refer to the Machine Leak Test procedure for instructions.
Check Shipping Pressure — To check for leaks that
have occurred during shipment on 2-piece machines:
1. Connect a pressure gage (30 psig [200 k Pa]) to a service
valve on each piece.
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 Machine LeakTest section for
instructions.
Provide Machine Protection — Ifthe machine will
not be installed immediately, it is very important to use a
drop cloth or plastic covering to protect the machine from
construction dirt and moisture before installation. Also, do
not remove protective shipping cover on control panel until
ready to use.
Job Data — Necessary information consists of: ma-
chine location drawings, piping drawings, field wiring diagrams, and rigging guide.

RIGGING AND POSITIONING
Rigging procedures vary depending on whether the ma-
chine is shipped in one or 2 pieces.
Rigging 2-Piece Units
PREPARATION — Two-piece units must be prepared for
installation before they can be rigged.
1. Open auxiliary evacuation valves to relieve pressure in
absorber-evaporator shell.
Lifting machine from points other than those specified
may result in serious damage and personal injury. Rigging equipment and procedure must be adequate for
machine weights and sizes. Refer to Table 1 for
machine weights, Fig. 2 and Tables 2 and 3 for overall
dimensions.
2. Open shipping valve on generator assembly to relieve
pressure.
3. Remove all piping end plates by flamecutting the end plate
and weld flange around their outer diameter. Cut these
pieces as shown in Fig. 5 for proper reconnection.
4. Grind the cut pieces smooth for a close fit when the machine pieces are assembled.
Carefully position cables on machine to avoid damage to
small piping, controls, or wiring.
contact the floor at the same time.
Keep shell horizontal when lifting or lowering so all legs
To avoid contaminates and debris getting into chiller,
do not leave machine open any longer than necessary.
RiggingOne-PieceUnits — Lift entire assembly with
cable hooks and shackles connected to the 3 lifting holes on
the absorber-evaporator assembly (lower part of machine),
and with the center balance point location, as shown in
Fig. 3 and 4. Lifting from other holes or locations can damage the machine. See Mounting the Burner section for burner
rigging instructions.
Do not remove any stock from pipe ends. Do not get
slag inside machine while flamecu<tting.
