Environmental

Temperature and humidity ranges

Operating the GC within the recommended ranges insures optimum
instrument performance and lifetime.
Recommended temperature range
20 to 27° C
Recommended humidity range
50 to 60%
Recommended altitude range
Up to 2000 m
After exposing the GC to extremes of temperature or humidity, allow 15
minutes for it to return to the recommended ranges.

Ventilation requirements

The GC is cooled by convection: air enters vents in the side panels and
underneath the instrument. Warmed air exits through slots in the top, rear,
and side panels. Do not obstruct air flow around the instrument.
Caution For proper cooling and general safety, always operate the instrument with
cover panels properly installed.

Venting oven exhaust

Hot air (up to 450°C) from the oven exits through a vent in the rear. Allow at
least 20 cm (10 inches) clearance behind the instrument to dissipate this air.
