Unpacking and
preparation
All units are carefully inspected
at the factory throughout the
entire fabrication and assembly
processes under Zehnder
Rittling’s stringent quality
assurance program.
Each unit is carefully packaged
in a cardboard container and
filled with kraft paper padding
for shipment to avoid damage
during normal handling in the
shipment process. It is the sole
responsibility of the customer
to provide the protection
necessary to prevent vandalism
and weather deterioration
of the equipment. Under no
condition should the units be left
unprotected from the elements.
If the equipment is not needed
immediately at the job site, it
should be left in its shipping
carton and stored in a clean,
dry area of the building or in a
warehouse. Do not remove any
equipment from its shipping
package until it is needed for
installation. The equipment
is NOT suitable for outdoor
installations.
After determining the condition of
the cardboard container exterior,
carefully remove each unit from
the container and inspect for
hidden damage. At this time,
check that all shipped loose
items are accounted for and
placed in a safe area. Any hidden
damage should be recorded
and immediately reported to
the carrier and a claim should
be filed. In the event a claim for
shipping damage is filed, the
unit, cardboard container, and all
packing must be kept for physical
inspection by the freight carrier.
Once the equipment is properly
positioned on the job site,
cover the units with either a
shipping carton, vinyl film, or an
equivalent protective covering.
Cap open ends of piping that is
stored on a job site. Take special
care to prevent foreign materials
from entering the units in areas
where painting, dry walling, or
spraying of fireproof material,
etc. has not yet been completed
as these materials may
accumulate on the coil. Foreign
material that accumulates
within the units can prevent
proper start-up, necessitate
costly clean-up operations,
or result in immediate or
premature component failure.
Before installing any of the
system components, be sure to
examine each pipe, fitting and
valve, and remove any dirt or
foreign material found in or on
these components. Some job
conditions may require some
form of temporary unit covering
during construction.
DO NOT store or install units
in corrosive environments or in
locations subject to temperature
or humidity extremes (e.g.,
attics, garages, rooftops, etc.).
Corrosive conditions and high
temperature or humidity can
significantly reduce system
performance, reliability and
overall service life.
