Installation Instructions
SAFETY CONSIDERATIONS
Absorption liquid chillers provide safe and reliable
service when operated within design specifica-
tions. When operating this equipment, use good judg-
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 NOT ALLOW 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.
