Absorption liquid chillers provide safe and reliable serv-
ice when operated within design speciﬁcations. When op-
erating 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 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 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 machine sec-
tions or the entire assembly.
DO NOT work on high-voltage equipment unless you are a
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-
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-
DO NOT syphon lithium bromide or any other chemical by
BE SURE all hydrogen has been exhausted before cutting
into purge chambers. Hydrogen mixed with air can explode
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.

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 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
machine is under pressure or while machine is running.
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
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
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.
USE only repaired or replacement parts that meet the code
requirements of the original equipment.
DO NOT ALLOW UNAUTHORIZED PERSONS to tamper
with 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
IMMEDIATELY wipe or ﬂush the ﬂoor if lithium bromide
or octyl alcohol is spilled on it.
