II. INSTALLATION
The MX170C is designed to be an exact replacement for the KING KX170A and similar
units. As a replacement unit, the MX is inserted directly into the mounting tray for the
KX170A and tightened down with an allen wrench
(9/64).
For new installations, the installation instructions for the KX170A should be used.
Equipment removal is accomplished by rotating the clamp screw counterclockwise a
few turns until it can be felt that the clamp screw is disengaged. Excessive torque on the
clamp screw will result disassembly of the clamp. After the clamp has been disengaged
the unit may be extracted by rocking the unit from side to side. The knobs should not be
used as extraction handles. A King Extraction tool # 071-6045-00 is also an acceptable
extraction device. Another method for extraction of a tight unit would be to rotate the
clamp screw counterclockwise until significant resistance is noted, the clamp screw can
then be pulled forward to expose the screw head. Grasp the screw head with a suitable
device and extraction force can be applied. Excessive side to side motion should not be
applied to the clamp screw.
