Installation Instructions
For use with Absorption Liquid Chillers
SAFETY CONSIDERATIONS
Absorption liquid chillers provide safe and reliable service
when operated within design specifications. When operat-
ing this equipment, use good judgment and safety precau-
tions 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 to purge lines or to pressurize a ma-
chine for any purpose. Oxygen gas reacts violently with many
common substances. Use nitrogen.
NEVER EXCEED specified test pressures. VERIFY the allow-
able test pressure by checking the instruction literature.
DO NOT VALVE OFF any safety device.
BE SURE that any pressure relief devices are properly installed
and functioning before operating any machine.
DO NOT USE eyebolts or eyebolt holes to rig machine sections
or the entire assembly.
DO NOT work on high-voltage equipment unless you are a quali-
fied 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 solid-state com-
ponents.
LOCK OPEN AND TAG electrical circuits during servicing. IF
WORK IS INTERRUPTED, confirm that all circuits are de-
energized before resuming work.
DO NOT syphon lithium bromide or any other chemical by mouth.
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.
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 absorption
machine, some noxious fumes may be produced. Ventilate the
area thoroughly to avoid breathing concentrated fumes.
NEVER APPLY an open flame or live steam to a refrigerant
cylinder. Dangerous overpressure can result. When neces-
sary to heat refrigerant, use only warm (110 F/43 C) water.
DO NOT REUSE disposable (nonreturnable) cylinders nor 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.
CAREFULLY INSPECT rupture discs AT LEAST ONCE A
YEAR. If machine operates in a corrosive atmosphere, inspect
the devices at more frequent intervals.
USE CARE when working near or in line with a compressed
spring. Sudden release of the spring can cause it and objects in
its path to act as projectiles.
IMMEDIATELY wipe or flush the floor if lithium bromide or
octyl alcohol is spilled on it.
DO NOT climb over machine. Use platform, catwalk or stag-
ing. Follow safe practices when using ladders.
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 open-
ing them.
Be aware that certain automatic start arrangements CAN EN-
GAGE THE STARTER. Open the disconnectahead of the starter
in addition to shutting off the machine or pump.
USE only repair or replacement parts that meet the code re-
quirements of the original equipment.
DO NOT VENT OR DRAIN water boxes containing industrial
brines, liquid, gases or semisolids without permission of your
process control group.
DO NOT LOOSEN water box cover bolts until the water box
has been completely drained.
DOUBLE-CHECK that coupling nut wrenches, dial indicators
or other items have been removed before rotating any shafts.
DO NOT LOOSEN a packing gland nut before checking that
the nut has a positive thread engagement.
PERIODICALLY INSPECT all valves, fittings, and piping for
corrosion, rust, leaks or damage.
PROVIDEADRAIN connection in the vent line near each pres-
sure relief device to prevent a build-up of condensate or rain
water.
