Operating Environment

VEN ILA ION REQUIREMEN S: When installing the product in a cabinet,
Caution
the convection into and out of the product must not be restricted. he
ambient temperature (outside the cabinet) must be less than the maximum
operating temperature of the product by 4 C for every 100 watts dissipated
in the cabinet. If the total power dissipated in the cabinet is greater than 800
watts, then forced convection must be used.
o meet the speci cations listed in chapter 1, you must operate this instrument within the
following limits:
Temperature
0 to +55 C (+32 to 131 F)

Altitude
4572 metres (15,000 feet)
Humidity
5 to 95% at +25 to +40 C (+77 to 104 F)
Protect the analyzer from temperature extremes which can cause internal
condensation.
Cooling
Leave 10 cm (4 in) of room at the rear of the cabinet and 7.6 cm (3 in) at
the sides of the cabinet. In bench stacking, the plastic feet provide adequate
clearance for the top and bottom surfaces. In rack mounting, ller strips
provide the clearance.
he rear-mounted fan moves air into the instrument and out through the
sides. Clean the fan regularly.
