Replacing a Cordset
To replace the heater or sensor on an applicator, replace the entire cordset
with a new or rebuilt cordset. You will need the following items:
S appropriate tools
S small rod for loosening a heater or sensor
S replacement cordset (new or rebuilt)
S heater lubricant for heaters
NOTE: Cordsets may be rebuilt by qualified personnel. To rebuild a cordset,
refer to http://emanuals.nordson.com/ or contact your Nordson
representative for a cordset rebuild instruction sheet (P/N1081985).
1. Disconnect and lock out electrical power to the system.
2. Disconnect the cordset that supplies power to the heater and/or sensor to
be replaced.
CAUTION! Risk of equipment damage. Disconnect electrical power to the
applicator before removing a sensor. Exposing a sensor to ambient air can
create a runaway heater condition, which can result in high temperatures that
could damage the applictor or attached components.
3. See Figure 11‐13. Replace the cordset, including the heater(s) and
sensor, as shown in the following table. Refer to the applicator reference
drawing provided in Applicator‐Specific Reference Drawings in Section8,
Parts, as needed.
Component Replacement Procedure
Heater(s) a. Loosen the heater retainer screw(s), rotate the heater retainer(s) to
free the heater(s), and remove the heater(s) from the manifold.
NOTE: If a heater does not easily slide out of its bore, locate the small
access hole on the bottom of the applicator. Insert a small rod in the
access hole and gently push or tap on the rod to loosen the heater.
b. Coat the new heater(s) with heater lubricant and insert the heater(s) in
the manifold.
c. Rotate the heater retainer(s) over the heater and tighten the screw(s).

NOTE: If the applicator has an access hole in the applicator body
directly behind the sensor, insert a rod into the access hole and gently
push or tap the sensor to loosen it. If the applicator does not have an
access hole, loosen the sensor by placing a small punch against the
center of the sensor and carefully tapping on the punch with a hammer
to loosen the seal between the sensor and the applicator body.

and turn the adapter about
