SECTION 3 – HANDLING, STORAGE, INSTALLATION AND REASSEMBLY
INSPECTION
The unit must be inspected prior to customer use by a
Johnson Controls Service representative. All damage
or possible damage must be reported to the transporta-
tion company. For more information, see
INSPECTION WINDOW
The inspection window of the exhaust gas duct or
chimney must not be in an area that is easily accessible.
If the exhaust gas duct or chimney has a problem from
a unit failure or exhaust gas deterioration, it may affect
the window. If the window must be installed, install a
guard fence around it.
If you need to use the inspection window,
please make sure the chiller-heater and
exhaust gas generator system (such as a
gas engine) are NOT operating.
INSTALLATION GUIDELINES
Exhaust gas duct fittings must be installed by a quali-
fied contractor. Defective exhaust gas duct work can
cause an oxygen-deficient accident or a fire.
When evacuating the nitrogen charge from
the factory, be sure the area is properly ven-
tilated. Failure to do this could result in suf-
focation.
When exhaust gas is emitted from the smokestack, do
not let it mix with the cooling water in the cooling tow-
er. Lower quality cooling water may result in corrosion
and scale formation.
As sulfides and carbides in the exhaust gas condense,
low temperature corrosion may occur. This may result
in tube perforations. Complications or serious injury
may occur.
The smokestack and cooling tower must be placed at
least 5 meters apart. Wherever possible, the smoke-
stack should be positioned downwind of the cooling
tower.
Each chiller-heater MUST have its own
chimney or exhaust gas duct. If two or
more chiller-heaters share a chimney,
there is a significant risk of exhaust gas
getting into a stopped chiller-heater, or
rust getting into a heat exchanger's parts.
When storing the absorption chiller unit after it has
been delivered, note the following potential issues:
1. Problems with machine in storage:
a. Breaking of thin pipes caused by freezing of
the refrigerant (water) sealed in the machine
and resulting air leak
b. Breaking and air leak due to external damage
c. Deterioration of electrical parts caused by
soot and dust
d. Deterioration of electrical parts caused by
rainwater (moisture)
e. Rusting of the machine body caused by rain-
water (moisture). Air leaks can cause serious
damage and are costly repairs. Therefore,
use diligence in keeping the machine body
free from moisture at all times.
2. Problems and Preventative Measures
PROBLEM
PREVENTATIVE MEASURE
Freezing of
refrigerant in
machine
Store the machine where the ambient
temperature is higher than 0°C. If the
ambient temperature drops below 0°C,
use a heater to warm the machine. If a
heater is not accessible, the following
options are also available to prevent
freezing:
• Extraction of the refrigerant
• Addition of antifreeze to the refrigerant
• Installation of a band heater
For further instruction, contact your
nearest authorized Johnson Controls
Service Center.
External
Damage
Avoid storing the machine in a place which is
easily accessible or near a construction site.
If this is unavoidable, provide the machine
with suitable protection.
