*1: The specifi cation determines the number of Explosion proof enclosures. No enclosures is needed for FM-Y
type.
*2: If an analyzer base sampling unit is provided, most applications require no external sampling equipment.
In addition, optimum sampling systems are prepared depending on various conditions. (For details, consult
Yokogawa. Optimal sampling systems will be offered.)
*3: For air purge piping, use stainless steel pipe of 1/2 inch or more.
*4: Power and contact output for system alarm 1 or annunciator are connected to control unit in case of FM-Y
type.
*5: Dehumidifi er can be optionally provided by Yokogawa. Other wiring cables, piping and installation materials
should be supplied by the user.
*6: Circuit breaker (30 AT or less) shall be suitable for the item of the power supply described in the
specifi cation, and located near the analyzer.
*7: Drain tank is needed only for GCs using FID/FPD. This is not used for GCs using TCD.
*8: Fix venting pipes properly so that the load of the venting pipes does not apply to the assembling vents of
this analyzer.
*9: The number of streams including one for calibration standard sample is as follows, in case of using GCSMP.
Type 1: Maximum of 7
Type 2: Maximum of 4
*10: Signal interrupters (disconnects) are required depending on the specifi cation.
