Carrier 16DF013-050 Installation Instructions Manual

Absorption liquid chiller/heaters provide safe and reliable
service when operated within design specifications. When
operating this equipment, use good judgment and safety pre-
cautions to avoid damage to equipment and property or in-
jury to personnel.
Be sure you understand and follow the procedures and safety
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 test pressures. For the 16DF ma-
chine, the maximum pressure is 12 psig (83 kPa). For the
chilled/hot water and condensing water piping, the maxi-
mum pressure is stamped on the machine.
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 maching 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 and operate the machine. Also, never operate the
machine when any safety devices are not adjusted and func-
tioning normally.
DO NOT REPEAT unsuccessful ignition attempts or restart
after flame failure without assurance that post-purge and pre-
purge have eliminated combustible gas or oil vapors from
the combustion chamber. DO NOT EVER ATTEMPT IG-
NITION 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 absorp-
tion machine, some noxious fumes may be produced. Ven-
tilate the area thoroughly to avoid breathing concentrated fumes.
Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.

Hermetic Absorption Liquid
DO NOT perform any welding or flamecutting to a machine
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 necesary
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, bleed off 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
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 indus-
trial 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 NOT ALLOW UNAUTHORIZED PERSONS to tamper
with burner equipment or machine safeties, or to make ma-
jor 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.
