General Installation Notes
The Hooded Combination Macro-Kjeldahl System is shipped in two sections. The
top exhaust bonnet and glass sashes will need to be installed after the main body
has been installed in its final location. Exhaust duct work, 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 2-9.
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. Hooded Combination Macro-Kjeldahl Systems are heavy and can not 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.
Bonnet Assembly
The hood bonnet must be installed on top of the substructure of the hood. This is
accomplished by elevating the bonnet up onto the top of the substructure. It is not
required to bolt the bonnet in place, as its weight on the foam gasket seal will hold
it in its proper place.
