UNPACKING THE SYSTEM
−Remove top of large box. Remove box's outer walls. Remove enclosure from
packing bag. IMPORTANT: Save all packing materials for subsequent use.
−Place enclosure on rigid desk or table. CAUTION: The enclosure is heavy (95+ lbs);
two people should lift the enclosure using handles on side. NOTE: Do not support
enclosure weight with the door, as doing so can adversely affect the door’s
alignment.
−Disengage latch and open enclosure door. Remove accessory wrench.
SWITCHING DOOR ORIENTATION
−The door can be hinged on the right or left side,
depending on which orientation is preferable for
continued use. The switch can be easily accomplished
using the 2.5 mm hex wrench provided in the
accessory bag. Remove the hex wrench from the
accessory bag.
−Use wrench to detach fill screws from door and body of enclosure. There are twelve
fill screws total. Keep fill screws for subsequent reattachment

Latch Attachment Screws
−Use wrench to detach latch attachment screws. Note
orientation of latch parts. Keep screws and latch parts for
subsequent reattachment.
−Support weight of enclosure door from below. Use
wrench to detach screws which attach the hinge to the
enclosure body. Remove door.
−Use wrench to detach hinges from door. Use wrench to
attach hinges to enclosure body on opposite side.
−Put enclosure door back into place and support weight
from below. Use wrench to attach hinge to door.
−Use wrench to reattach door latch. Use wrench to
reattach fill screws.
INSTALL INSTRUMENT
At this point, install the instrument to be used inside the enclosure. Please refer to
instrument manual for instructions on installing instrument.

CABLE MANAGEMENT
−There are cable ports on both sides of the enclosure. Upon installing instrument,
decide which side of the enclosure the instrument cables should be ported
through. If necessary, remove port cover and place in port which will not be
used.
−Remove damping foam from cable port to be used. Feed instrument cables out
through port.
−Outside of enclosure, compress two pieces of damping foam around cables.
Push foam and cables into cable port (see picture above). Adjust as necessary to
ensure a good seal around the cables.
MAINTENANCE
−The enclosure can be cleaned using general cleaning agents and a soft cloth. Do
not use abrasive cleaning materials as it may degrade the paint.
−Keep enclosure door closed and latched when the enclosure is not in use to avoid
undue strain on hinges.
−Contact Herzan for replacement parts.

BEST PRACTICES
−When choosing a location for the enclosure, avoid rooms in close proximity to
noise-generating machines, such as production machines, large HVAC systems,
or elevator shafts. If possible, choose a room on the ground floor. Avoid
rooms with raised floors.
−Avoid places within the room that are near open doors, open windows, HVAC
ducts, and high foot traffic areas. To reduce overall vibration levels, place the
enclosure near a load-bearing wall.
−Place the enclosure on a rigid table or desk. Tables or desks which lack rigidity
may impart additional noise into the system.
−Don’t place noise-generating equipment such as CPUs or pumps on the
enclosure or on the supporting table. If possible, place noise-generating
equipment in a separate room.
−Cables entering the enclosure should be slack. Stiff cables transmit parasitic
vibrations. If the cables connect to noise-generating equipment, weight should
be added to cables to dampen transmission of noise.
−Before beginning sensitive measurements, close and latch the enclosure door.
UPGRADES

of your enclosure. Please contact Herzan to learn more. Upgrades include:
−Air-based vibration isolation
