INSTALLING THE LAMP AND ARC
SENSOR OPTIONS
The optional K1706-1 Work Lamp package provides
a lamp and convenient hood-mounted switches for
both the light and Mobiflex 400-MS fan. The optional
K1706-2 Work Lamp with arc sensor package
includes a built-in Automatic start/stop arc sensor to
automatically switch the Mobiflex fan on and off when
the sensor detects an arc flash. This arc sensor is
built-in to the lamp housing. (The K1670-1 is available
to retrofit an arc sensor into the K1706-1)
GENERAL PREPARATION
1. Pop out the sealing plate (Fig. 7, Item A) on the top
of the hood with a screwdriver.
2. Remove the six screws (Fig. 7, Item C) and the air-
flow focus vanes (Fig. 7, Item B).
3. Open the airflow throttle valve (Fig. 7, Item D).
MOUNTING THE LAMP HOUSING IN THE HOOD
Feed the lamp (and sensor leads, if used) through the
hole (Fig. 8, Item A) in the top of the hood; push the
top leg of the lamp housing into position, then snap in
the bottom leg. Remount the airflow focus vanes in
the open end of the hood, using the six screws (Fig. 7,
Item C).
MAKING THE CONNECTIONS AT THE HOOD
