located in the top of the operator panel
a) Separate power switches are provided for the main and auxiliary oil mist generators in
NEC configured units. The auxiliary oil mist generator switch is located on the right side.
Move the switch to the OFF position.
b) For ATEX configured units, power is supplied through a three-position selector switch. To

the air pressure regulator in the full counter clockwise position places it in the closed
position. The mist pressure will bleed to zero.

Mist Outlet Switching Valve
The Model IVT Oil Mist Generator console is equipped with a pneumatically operated switching
valve that automatically connects the mist outlet of either the main or auxiliary oil mist generator
to the mist outlet pipe. When the air pressure is being supplied to the main oil mist generator the
mist outlet is open to the main oil mist generator and closed to the auxiliary unit. When the
auxiliary oil mist generator is operating the mist outlet valve automatically opens to the discharge
of the auxiliary oil mist generator and blocks the outlet to the main oil mist generator. If air is
being supplied to both the main and the auxiliary units, both outlet connections are open and both
units discharge mist into the distribution header system.
NOTICE:
The main and auxiliary oil mist generators should not be operated in
parallel. The fail open design is intended to safe guard against
unintentional improper switching between the main and auxiliary oil
mist generator. Failure to properly follow instructions may result in a
high mist pressure condition.
