PROBLEM SOLUTION
THREADED ADAPTER DOES NOT FIT
INOT THE CONDUIT.
1. Wrong size threaded adapter was
selected
MISSILE GOES INTO CONDUIT A
DISTANCE BUT WILL NOT EXIT AT
OTHER END.
1. If air is escaping at the exit end, the
air is bypassing the missile. The
missile is either worn out or is the
wrong size for the conduit in
which it is being used. The missile
will have to be pulled back out of
the conduit and replaced. Follow
the removal process for the seal-off
body assembly as listed in the
previous section and use the winch
truck to pull back the missile.
2. If no losses are found at either end
of the conduit run, the missile may
have stopped due to a conduit
obstruction or due to an unsealed
conduit run. In the latter case, the
Condux Winch Line Blower will
not properly function. In this
instance, the seal-off body
assembly must be removed from
the conduit as described in the
previous section, the missile must
be pulled back out of the conduit
by the winch line, and another
method of inserting the winch line
into the conduit must be used.
