GC, GC/MS, and ALS Site Preparation Guide 23
USA fast heating oven, 240 V
The 240 V fast heating oven requires 240 V/15 A power. Do not use 208 V
power. Lower voltage causes slow oven ramps and prevents proper
temperature control. The power cord supplied with your GC is rated for
250 V/15 A, and is a two- pole, three- wire cord with grounding (type
L6- 15R/L6- 15P).
Canadian installation
When installing a GC in Canada, make sure your GC’s power supply
circuit meets the following additional requirements:
• The circuit breaker for the branch circuit, which is dedicated to the
instrument, is rated for continuous operation.
• The service box branch circuit is marked as a “Dedicated Circuit.”
