General Installation Notes
The Open Combination Macro-Kjeldahl System is shipped fully assembled.
Exhaust duct work, remote blower (if required), electrical service, water supply
and drain connections should be completed by a licensed contractor.
The customer will need to purchase their preferred size of Kjeldahl Flasks, with
one-hole-rubber-stoppers and distillate receiving flasks. The glass Connecting
Bulbs and Delivery Tubes are provided with each Kjeldahl System.
Connecting Bulbs and Delivery Tubes
are included with Macro Kjeldahl Systems.
For installation of the Connecting Bulbs
and Delivery Tubes see section on Glassware
Installation and Figure 2-8.
Use caution when you remove the protective packaging material taped to the
heater runways as fragile components are involved. Levelers are shipped
installed, as are the distillation cooling water thermometers.
Location
If possible, the apparatus should be uncrated in the room in which it is to be
placed. Open Combination Macro-Kjeldahl Systems are heavy and cannot be
disassembled to reduce their overall size. Special arrangements should be made in
advance for moving the systems to their final location within a facility. Special
instruction tags are attached to the apparatus; they must not be removed until the
installation has been completed.
The Open Combination Kjeldahl System does not include a safety enclosure. It is
strongly advised to install this Kjeldahl in a location segregated away from
normal Laboratory personnel traffic. High heats along with boiling acids and
caustics present a safety hazard to personnel in close proximity to the Open
Combination Kjeldahl System. Also recommended is spot exhaust ventilation for
the final installation location to remove excess heat produced by the Kjeldahl
digestion and distillation heaters.
