General Specifications and Site Readiness
The Vial Heater Module should be placed in a
work area with adequate room for normal use,
including loading and unloading of vials, and
sufficient room for fan cooling behind the
module.
The fiber optic probes are attached on the left
and right sides of the module as shown in the
photo. Leave room for an adequate bend radius
of the fiber bundles. Fiber bundles should not be
kinked, and should not be bent in a radius of less
than 15 cm (6”).
The Metrohm NIRSystems instrument should also have adequate room for fan circulation. The system
should be mounted on a bench or work location free from vibration, direct sunlight, drafts, and
sudden changes in temperature or humidity.
The Vial Heater Module is supplied with AC power cords for both North American and international
use. The cord for international use is a “Harmonized International Power Cord” with color-coded,
stripped leads for use with approved local wiring connectors. A User Manual and a Spare Fuse
(T5A-250) are supplied.
If vials are loaded in the immediate vicinity of the equipment, care should be taken to avoid spills or
drippage onto the Vial Heater Module. A lab sink or other facilities should be provided.
