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. All major
components and subassemblies
such as motors, blowers,
coils, controls, valve packages
and paint quality are carefully
tested for proper operation,
visually inspected and verified
for full compliance with factory
standards. Operational testing
for some customer furnished
components such as pneumatic
valves and DDC controllers may
be a possible exception.
Room Fan Coils are usually
shipped on pallets of up to 5
units. Each unit is factory tagged
according to the customer’s
purchase order. This allows the
unit, upon removal from the
pallet, to be taken directly to its’
assigned space for immediate
installation. Units should not be
installed at locations other than
that designated on the tag.
Each unit is carefully packaged
in a polyethylene plastic bag
for surface protection, placed
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
components. All manufacturer’s
warranties are void if foreign
material is allowed to be
deposited in the drain pan or on
the motor or blower wheels of
any unit. 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.
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 such as wall
mounted thermostats, changeover
switches, remote temperature
sensors, auxiliary drain pans, valve
packages, etc. 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 in
the drain pan or on the motors and
blower wheels. 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
